Size and connectivity make sense for both gaming and work; getting the most from it requires choosing the color mode and controlling light reaching the screen.<\/p><p class=\"wp-block-paragraph\">Its practical advantages are uniform brightness, 90 W USB-C, and panel-protection options. HDR modes, reflections from the glossy finish, and price relative to the equivalent MSI most influence the choice.<\/p><h2 class=\"wp-block-heading\" id=\"review-montaje-construccion-y-conexiones\">Assembly, construction, and connections<\/h2><p class=\"wp-block-paragraph\">Asus usually puts considerable care into packaging, and does so again here. It is more than simply taking the monitor out of the box. Presentation and accessories show attention, including a cable pouch and a fairly complete set of extras.<\/p><p class=\"wp-block-paragraph\">The stand is the same one Asus uses on other models, which honestly seems a good choice. Some brands change things for the sake of it, but when something works, it is better not to alter it too much.<\/p><ul class=\"wp-block-list\"><li><strong>Base with a phone slot<\/strong><\/li><li><strong>Threaded mount on the back<\/strong> for attaching a camera, for example<\/li><li><strong>Full ergonomic adjustment<\/strong>: height, forward tilt, backward tilt, swivel, and portrait pivot<\/li><li><strong>Swivel without moving the base<\/strong>, always welcome on a desk<\/li><\/ul><p class=\"wp-block-paragraph\">Build quality is good. It feels solid and well finished, with Asus&#8217;s gaming styling without going overboard. There is also rear RGB for those who value it.<\/p><p class=\"wp-block-paragraph\">Connectivity is well covered. It is not one of those monitors that falls short and forces adapters from day one. The highlight is <strong>USB-C with up to 90 W charging<\/strong>, very useful for connecting a laptop and handling practically everything with a single cable.<\/p><ul class=\"wp-block-list\"><li><strong>USB-C with 90 W<\/strong><\/li><li><strong>HDMI 2.1<\/strong><\/li><li><strong>PIP and KVM features<\/strong><\/li><li><strong>Joystick for menu navigation<\/strong><\/li><\/ul><p class=\"wp-block-paragraph\">The OSD joystick is another simple but important detail. An expensive monitor with awkward menus leaves you adjusting fewer settings than you should. Navigation is comfortable here.<\/p><figure class=\"wp-block-gallery has-nested-images columns-2 wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\"><figure class=\"wp-block-image size-large\"><a href=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/asistente-rog-xg27ucdmg-peana-unboxing-1.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" data-id=\"2039\" src=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/asistente-rog-xg27ucdmg-peana-unboxing-1-1024x576.jpg\" alt=\"ASUS XG27UCDMG assembly and stand\" class=\"wp-image-2039\" srcset=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/asistente-rog-xg27ucdmg-peana-unboxing-1-1024x576.jpg 1024w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/asistente-rog-xg27ucdmg-peana-unboxing-1-300x169.jpg 300w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/asistente-rog-xg27ucdmg-peana-unboxing-1-768x432.jpg 768w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/asistente-rog-xg27ucdmg-peana-unboxing-1.jpg 1280w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">ASUS XG27UCDMG assembly and stand<\/figcaption><\/figure>\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/asus-rog-xg27ucdmg-panel-de-puertos-usbc-90w-1.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" data-id=\"2078\" src=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/asus-rog-xg27ucdmg-panel-de-puertos-usbc-90w-1-1024x576.jpg\" alt=\"Monitor connections, including 90 W USB-C\" class=\"wp-image-2078\" srcset=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/asus-rog-xg27ucdmg-panel-de-puertos-usbc-90w-1-1024x576.jpg 1024w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/asus-rog-xg27ucdmg-panel-de-puertos-usbc-90w-1-300x169.jpg 300w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/asus-rog-xg27ucdmg-panel-de-puertos-usbc-90w-1-768x432.jpg 768w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/asus-rog-xg27ucdmg-panel-de-puertos-usbc-90w-1.jpg 1280w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">Monitor connections, including 90 W USB-C<\/figcaption><\/figure><\/figure><h2 class=\"wp-block-heading\" id=\"review-glossy-y-4k-definicion-con-luz-controlada\">Glossy and 4K: definition with controlled lighting<\/h2><p class=\"wp-block-paragraph\">The <strong>Asus ROG XG27UCDMG<\/strong> uses the classic glossy finish found on practically every QD-OLED on the market. It has a clear advantage and an equally clear drawback.<\/p><p class=\"wp-block-paragraph\"><strong>Advantage:<\/strong> colors look spectacular, very vivid, with a beautifully clean image.<\/p><p class=\"wp-block-paragraph\"><strong>Drawback:<\/strong> reflections are unforgiving.<\/p><p class=\"wp-block-paragraph\">Direct light on the panel can also give blacks a magenta tint. That is not specific to Asus, but to this technology. If you plan to buy the <strong>Asus ROG XG27UCDMG<\/strong>, some control over the environment is advisable.<\/p><p class=\"wp-block-paragraph\">In other words, a window behind you or a lamp aimed at the panel does no favors to this model or almost any QD-OLED.<\/p><p class=\"wp-block-paragraph\">OLED text clarity often raises concerns because of subpixel layouts. On QD-OLED panels, that can be more noticeable compared with traditional IPS, but here there is a decisive factor: <strong>27 inches and 4K resolution<\/strong>.<\/p><p class=\"wp-block-paragraph\">Pixel density is so high that text looks really good. In fact, within QD-OLED, this class of monitor offers some of the best text definition.<\/p><p class=\"wp-block-paragraph\">If text concerns were holding you back for desktop use, productivity, or reading, you can feel quite reassured here.<\/p><figure class=\"wp-block-image size-large\"><a href=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/asus-rog-xg27ucdmg-reflejos-panel-glossy-qdoled-1.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/asus-rog-xg27ucdmg-reflejos-panel-glossy-qdoled-1-1024x576.jpg\" alt=\"Reflections on the glossy QD-OLED finish\" class=\"wp-image-2081\" srcset=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/asus-rog-xg27ucdmg-reflejos-panel-glossy-qdoled-1-1024x576.jpg 1024w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/asus-rog-xg27ucdmg-reflejos-panel-glossy-qdoled-1-300x169.jpg 300w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/asus-rog-xg27ucdmg-reflejos-panel-glossy-qdoled-1-768x432.jpg 768w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/asus-rog-xg27ucdmg-reflejos-panel-glossy-qdoled-1.jpg 1280w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">Reflections on the glossy QD-OLED finish<\/figcaption><\/figure><h2 class=\"wp-block-heading\" id=\"review-color-en-sdr-escoger-la-gama-adecuada\">SDR color: choosing the appropriate gamut<\/h2><p class=\"wp-block-paragraph\">The monitor includes a mode that is <strong>calibrated for sRGB<\/strong>. It defaults to around 115 nits, although brightness can be changed without disrupting the gamut too much. That is well implemented and flexible.<\/p><p class=\"wp-block-paragraph\">Color accuracy is decent, grayscale balance acceptable, and color temperature somewhat warm, without straying too far from the 6500K target. sRGB gamma tracking, as is common on QD-OLED, is not perfect. There is a somewhat high peak, but nothing dramatic.<\/p><p class=\"wp-block-paragraph\">Outside that professional mode, the monitor can also be limited to sRGB while other parameters are adjusted manually. That is very useful if you like fine-tuning panel behavior to taste.<\/p><div class=\"wp-block-group mg-review-evidence\"><div class=\"wp-block-group__inner-container is-layout-flow wp-block-group-is-layout-flow\"><figure class=\"wp-block-gallery has-nested-images columns-2 wp-block-gallery-2 is-layout-flex wp-block-gallery-is-layout-flex\"><figure class=\"wp-block-image size-large\"><a href=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-404.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" data-id=\"7092\" src=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-404-1024x576.jpg\" alt=\"Coverage \u00b7 sRGB mode\" class=\"wp-image-7092\" srcset=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-404-1024x576.jpg 1024w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-404-300x169.jpg 300w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-404-150x84.jpg 150w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-404-768x432.jpg 768w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-404.jpg 1920w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">Coverage \u00b7 sRGB mode<\/figcaption><\/figure>\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-406.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" data-id=\"7094\" src=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-406-1024x576.jpg\" alt=\"Grayscale \u00b7 sRGB\" class=\"wp-image-7094\" srcset=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-406-1024x576.jpg 1024w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-406-300x169.jpg 300w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-406-150x84.jpg 150w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-406-768x432.jpg 768w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-406.jpg 1920w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">Grayscale \u00b7 sRGB<\/figcaption><\/figure><\/figure><p class=\"wp-block-paragraph\">sRGB mode combines a useful gamut clamp with adjustable brightness. Grayscale distinguishes that good saturation control from the slightly warm white tendency and gamma deviations.<\/p><p class=\"mg-review-evidence-link wp-block-paragraph\"><a href=\"https:\/\/monitorgarage.com\/en\/monitor\/asus-rog-xg27ucdmg\/#mg-fiche-4862-1galeria\">View all tests in the gallery \u2192<\/a><\/p><\/div><\/div><p class=\"wp-block-paragraph\">There is also a clamp for <strong>DCI-P3<\/strong>. Compared with Racing mode, the result is good. Coverage is around <strong>97,5%<\/strong> and accuracy is again good.<\/p><p class=\"wp-block-paragraph\">Grayscale balance behaves similarly to sRGB. Color temperature follows the same pattern and gamma attempts to track 2.2. If measurements show unusual shapes in RGB balance, that is not strange for OLED. Some irregularity comes from the panel&#8217;s own flickering during measurement.<\/p><p class=\"wp-block-paragraph\">To get all the monitor&#8217;s colors for gaming, use <strong>Wide Gamut mode<\/strong>. There, the <strong>Asus ROG XG27UCDMG<\/strong> exceeds <strong>99% DCI-P3 coverage<\/strong> with settings similar to those above.<\/p><p class=\"wp-block-paragraph\">The trade-off is the usual one: some oversaturation, particularly in red, because the panel extends beyond that gamut. Honestly, for gaming I do not see that as a major problem. In fact, many people will like the extra visual punch.<\/p><p class=\"wp-block-paragraph\">Adobe RGB also exceeds <strong>95% coverage<\/strong>, although there is an important caveat: <strong>there is no dedicated Adobe RGB mode<\/strong>. Manual calibration can get it quite close, but out of the box it is not specifically designed for that space.<\/p><p class=\"wp-block-paragraph\">A professional meter and ICC profile can get even more from the <strong>Asus ROG XG27UCDMG<\/strong>. Manual DCI-P3 D65 calibration further improves grayscale balance and color accuracy.<\/p><p class=\"wp-block-paragraph\">In fact, post-calibration results are among the best I have seen on tested monitors with this type of panel. But remember: even copying another unit&#8217;s settings will never produce an identical result. Even within the same model, every panel has small variations.<\/p><p class=\"wp-block-paragraph\">To get it ready for gaming without overcomplicating things, this is a sensible setup:<\/p><ul class=\"wp-block-list\"><li><strong>Wide Gamut mode<\/strong><\/li><li><strong>Racing mode<\/strong><\/li><li><strong>Gamma 2.2<\/strong><\/li><li><strong>Color temperature at 6500K<\/strong><\/li><\/ul><h2 class=\"wp-block-heading\" id=\"review-brillo-uniforme-para-escritorio\">Uniform brightness for desktop use<\/h2><p class=\"wp-block-paragraph\">With those general-use settings, the <strong>Asus ROG XG27UCDMG<\/strong> delivers around <strong>261 nits on a full white screen at 100% APL<\/strong>. Here is one of my favorite features on the monitor: <strong>uniform brightness control<\/strong>.<\/p><p class=\"wp-block-paragraph\">Enable this option and brightness remains constant regardless of content. It also improves both brightness and color uniformity. If you plan to use the monitor for work, this feature makes a lot of sense.<\/p><p class=\"wp-block-paragraph\">Disable it, and brightness becomes variable while color uniformity also worsens. I would not recommend that for work, but it can be appealing for content and games, because you can see <strong>peaks around 450 nits in SDR<\/strong>. Essentially, it behaves like a kind of True Black 400 in SDR.<\/p><h2 class=\"wp-block-heading\" id=\"review-hdr-cuando-compensa-cada-modo\">HDR: when each mode is worthwhile<\/h2><p class=\"wp-block-paragraph\">In HDR, the <strong>Asus ROG XG27UCDMG<\/strong> offers several modes. One is <strong>DisplayHDR True Black 400<\/strong>. There are also <strong>three modes with a 1000-nit peak<\/strong>. Some parameters can also be unlocked and customized, although excessive changes are usually not worthwhile because they worsen calibration.<\/p><p class=\"wp-block-paragraph\">As on almost all QD-OLEDs, the best calibration from 10% APL upward is usually in the mode <strong>True Black<\/strong>. The problem is that it is limited to around <strong>450-460 nits<\/strong>.<\/p><p class=\"wp-block-paragraph\">TrueBlack 400 calibration is decent for this panel type. The other modes fall somewhat behind.<\/p><p class=\"wp-block-paragraph\">For maximum peak brightness, switch to the 1000-nit modes. In small windows, around 2% APL, most do approach those 1000 nits. In my view, the best-balanced mode is <strong>HDR Console<\/strong>. Gaming is also good, but Console seems the most refined in calibration.<\/p><p class=\"wp-block-paragraph\">In that mode, the monitor reaches around <strong>1015 nits peak<\/strong>, exactly what you would expect from this type of QD-OLED.<\/p><p class=\"wp-block-paragraph\">However, do not confuse peak brightness with a brighter overall image. In many scenes,\u00a0<strong>True Black 400<\/strong> mode can look slightly brighter overall. That is why no mode is universally best. It depends considerably on the content.<\/p><p class=\"wp-block-paragraph\">There is also a <strong>brightness boost<\/strong> setting that makes the overall image brighter, but affects HDR calibration in exchange.<\/p><div class=\"wp-block-group mg-review-evidence\"><div class=\"wp-block-group__inner-container is-layout-flow wp-block-group-is-layout-flow\"><figure class=\"wp-block-gallery has-nested-images columns-2 wp-block-gallery-3 is-layout-flex wp-block-gallery-is-layout-flex\"><figure class=\"wp-block-image size-large\"><a href=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-421.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" data-id=\"7106\" src=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-421-1024x576.jpg\" alt=\"HDR Gaming \u00b7 10%\" class=\"wp-image-7106\" srcset=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-421-1024x576.jpg 1024w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-421-300x169.jpg 300w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-421-150x84.jpg 150w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-421-768x432.jpg 768w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-421.jpg 1920w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">HDR Gaming \u00b7 10%<\/figcaption><\/figure>\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-423.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" data-id=\"7108\" src=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-423-1024x576.jpg\" alt=\"HDR Gaming \u00b7 100%\" class=\"wp-image-7108\" srcset=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-423-1024x576.jpg 1024w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-423-300x169.jpg 300w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-423-150x84.jpg 150w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-423-768x432.jpg 768w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/09\/asus-rog-xg27ucdmg-prueba-p2-423.jpg 1920w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">HDR Gaming \u00b7 100%<\/figcaption><\/figure><\/figure><p class=\"wp-block-paragraph\">These two windows show why illuminated area matters: higher-peak modes can emphasize small lights while darkening some midtones in larger scenes.

Despite incomplete gamut coverage, HDR calibration seems quite acceptable to me.<\/p><p class=\"wp-block-paragraph\">Color volume, which accounts for brightness as well as gamut, reaches <strong>almost 72% BT.2020<\/strong>. That is a wide result and fits QD-OLED expectations: intense, highly saturated colors.<\/p><h2 class=\"wp-block-heading\" id=\"review-movimiento-a-240-hz-y-elmb-a-120-hz\">Motion at 240 Hz and ELMB at 120 Hz<\/h2><p class=\"wp-block-paragraph\">There are few surprises here, which is good. This is a <strong>4K 240 Hz OLED<\/strong>, so gray-to-gray transitions are virtually instant. Response is excellent, without transitions showing excessive overshoot.<\/p><p class=\"wp-block-paragraph\">In motion, the <strong>Asus ROG XG27UCDMG<\/strong> performs as a monitor at this level should.<\/p><p class=\"wp-block-paragraph\">Asus also includes <strong>ELMB<\/strong>, meaning a system of <strong>black frame insertion<\/strong>. Set the monitor to <strong>120 Hz<\/strong> and enable this mode, and you can achieve motion clarity very similar to 240 Hz.<\/p><p class=\"wp-block-paragraph\">There is one small catch: with uniform brightness enabled, ELMB cannot be activated. You must disable uniform brightness first.<\/p><p class=\"wp-block-paragraph\">The mode works quite well and seems especially useful in two scenarios:<\/p><ul class=\"wp-block-list\"><li>When your PC cannot reach 240 fps<\/li><li>When using a device limited to 120 Hz, such as PS5<\/li><\/ul><p class=\"wp-block-paragraph\">The drawback is the usual one with these technologies: <strong>brightness drops somewhat<\/strong>.<\/p><p class=\"wp-block-paragraph\">For input lag, the <strong>Asus ROG XG27UCDMG<\/strong> delivers completely normal values at both <strong>240 Hz<\/strong> and <strong>120 Hz<\/strong>. At <strong>60 Hz<\/strong> it is slightly above other models such as the MSI I compared recently, but in practice the difference is very few milliseconds. You will not notice it.<\/p><p class=\"wp-block-paragraph\">There is also support for <strong>VRR<\/strong>, so it can be used with Adaptive Sync, FreeSync, or G-Sync. I tested it with an Nvidia graphics card. However, it is not officially certified by Nvidia.<\/p><p class=\"wp-block-paragraph\">As you would expect from a QD-OLED monitor, there is <strong>some flicker with VRR<\/strong>. This is not unique to this model. It is fairly common across OLED monitors.<\/p><p class=\"wp-block-paragraph\">The interesting part is that Asus has added <strong>OLED Anti-Flicker<\/strong> technology with two levels: <strong>Middle<\/strong> and <strong>High<\/strong>. It does not eliminate the problem entirely, but it does reduce it.<\/p><p class=\"wp-block-paragraph\">The tradeoff is that the VRR range changes depending on the selected mode. In High mode, there is also a specific refresh-rate band where VRR does not work. Middle mode strikes me as the best balance.<\/p><p class=\"wp-block-paragraph\">It also changes how <strong>LFC<\/strong>behaves, triggering it at higher refresh rates than when this technology is disabled.<\/p><p class=\"wp-block-paragraph\">It is no miracle cure, but it is a useful addition. And in a market where many models simply accept flicker as a given, it is nice to see Asus at least trying to mitigate it.<\/p><figure class=\"wp-block-image size-large\"><a href=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/avisos-osd-asus-rog-xg27ucdmg-elmb-2.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/avisos-osd-asus-rog-xg27ucdmg-elmb-2-1024x576.jpg\" alt=\"OSD warning when setting up ELMB\" class=\"wp-image-2721\" srcset=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/avisos-osd-asus-rog-xg27ucdmg-elmb-2-1024x576.jpg 1024w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/avisos-osd-asus-rog-xg27ucdmg-elmb-2-300x169.jpg 300w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/avisos-osd-asus-rog-xg27ucdmg-elmb-2-768x432.jpg 768w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/avisos-osd-asus-rog-xg27ucdmg-elmb-2.jpg 1280w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">OSD warning when setting up ELMB<\/figcaption><\/figure><h2 class=\"wp-block-heading\" id=\"review-consolas-productividad-y-cuidado-del-oled\">Consoles, productivity, and OLED care<\/h2><p class=\"wp-block-paragraph\">Good news here. The <strong>Asus ROG XG27UCDMG<\/strong> is fully compatible with <strong>PlayStation 5<\/strong> thanks to HDMI 2.1. That means:<\/p><ul class=\"wp-block-list\"><li><strong>4K at 120 Hz<\/strong><\/li><li><strong>VRR<\/strong><\/li><li><strong>ALLM<\/strong><\/li><\/ul><p class=\"wp-block-paragraph\">If you play games that reach 120 fps, enabling ELMB can improve motion clarity. For console use, I consider it a real benefit, not just a marketing feature that never makes it beyond the spec sheet.<\/p><p class=\"wp-block-paragraph\">The <strong>Asus ROG XG27UCDMG<\/strong> goes beyond gaming. It has several features that also make it a sensible multipurpose monitor:<\/p><ul class=\"wp-block-list\"><li><strong>PIP<\/strong><\/li><li><strong>KVM<\/strong><\/li><li><strong>USB-C with 90 W<\/strong><\/li><\/ul><p class=\"wp-block-paragraph\">Asus also includes its usual set of burn-in prevention measures:<\/p><ul class=\"wp-block-list\"><li>Pixel shifting<\/li><li>Pixel refresh<\/li><li>Logo dimming<\/li><\/ul><p class=\"wp-block-paragraph\">Here is one of the monitor&#8217;s coolest features. The <strong>Asus ROG XG27UCDMG<\/strong> includes a <strong>proximity sensor<\/strong>. You can configure the time and distance, and the monitor turns off or on depending on whether you are sitting in front of it.<\/p><p class=\"wp-block-paragraph\">I found this feature works really well. I cannot say how well it distinguishes a person from an object, as another, more advanced MSI monitor with an integrated NPU did, but it is more than adequate for most uses.<\/p><p class=\"wp-block-paragraph\">Also, if anyone has experienced odd behavior with this feature, my recommendation is clear: <strong>update the monitor&#8217;s firmware<\/strong>. In my experience, it has worked quite well.<\/p><figure class=\"wp-block-image size-large\"><a href=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/ps5-informacion-hdmi-conectado-vrr-48-120-hz-hdr-asus-rog-xg27ucdmg-1.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/ps5-informacion-hdmi-conectado-vrr-48-120-hz-hdr-asus-rog-xg27ucdmg-1-1024x576.jpg\" alt=\"Signal features recognized by PS5\" class=\"wp-image-2755\" srcset=\"https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/ps5-informacion-hdmi-conectado-vrr-48-120-hz-hdr-asus-rog-xg27ucdmg-1-1024x576.jpg 1024w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/ps5-informacion-hdmi-conectado-vrr-48-120-hz-hdr-asus-rog-xg27ucdmg-1-300x169.jpg 300w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/ps5-informacion-hdmi-conectado-vrr-48-120-hz-hdr-asus-rog-xg27ucdmg-1-768x432.jpg 768w, https:\/\/monitorgarage.com\/wp-content\/uploads\/2026\/05\/ps5-informacion-hdmi-conectado-vrr-48-120-hz-hdr-asus-rog-xg27ucdmg-1.jpg 1280w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">Signal features recognized by PS5<\/figcaption><\/figure><h2 class=\"wp-block-heading\" id=\"review-que-elegir-frente-a-los-otros-oled-4k\">How it compares with other 4K OLEDs<\/h2><p class=\"wp-block-paragraph\">The price of the <strong>Asus ROG XG27UCDMG<\/strong> is hardly a bargain. It sits at <strong>under 900 euros<\/strong>, putting it at virtually the same level as the<strong> MSI MPG 272URX<\/strong>\u00a0 , which uses the same panel.<\/p><p class=\"wp-block-paragraph\">And, naturally, that raises the question: if they use the same panel, which is the better buy?<\/p><p class=\"wp-block-paragraph\">In terms of color, baseline calibration, and overall image performance, the two are very similar. The real differences are in their features.<\/p><ul class=\"wp-block-list\"><li><strong>98 W USB-C<\/strong> instead of 90 W<\/li><li><strong>DisplayPort 2.1<\/strong>, which this Asus lacks<\/li><\/ul><ul class=\"wp-block-list\"><li><strong>A stand I prefer<\/strong><\/li><li><strong>SDR uniform brightness control<\/strong> that can be enabled or disabled<\/li><li><strong>Higher peak SDR brightness<\/strong> with uniform brightness disabled<\/li><li><strong>Proximity sensor<\/strong><\/li><li><strong>Anti-flicker technology for VRR<\/strong><\/li><\/ul><p class=\"wp-block-paragraph\">Regarding <strong>DisplayPort 2.1<\/strong>, I already mentioned at the time that, in practice, it currently offers no clear improvement in everyday use. In theory, and looking ahead, it could have value. If a technology that depends on DisplayPort 2.1 arrives tomorrow, the MSI will have that extra capability. But when it comes to things you can actually notice right now, the Asus feels more fully featured to me.<\/p><p class=\"wp-block-paragraph\">That is why, between the two, <strong>I slightly prefer the Asus<\/strong>. That said, the price difference is decisive. If the MSI is considerably cheaper, choosing it would make perfect sense. And if the reverse is true, the same applies in favor of the Asus.<\/p><p class=\"wp-block-paragraph\">If you want the most fully featured version in this family, Asus offers a higher-end model with the same panel and more extras.<\/p><p class=\"wp-block-paragraph\">That model includes:<\/p><ul class=\"wp-block-list\"><li><strong>DisplayPort 2.1<\/strong><\/li><li><strong>Dolby Vision<\/strong><\/li><li>A more premium stand<\/li><\/ul><p class=\"wp-block-paragraph\">However, its price also approaches <strong>1200 euros<\/strong>. At that point, you need to decide how much it is worth paying extra to have absolutely everything.<\/p><p class=\"wp-block-paragraph\">Although the <strong>Asus ROG XG27UCDMG<\/strong> strikes me as a very good monitor, I still feel the same way as I do about other similar models: personally, I prefer <strong>32 inches<\/strong> for all-around use.<\/p><p class=\"wp-block-paragraph\">That does not mean 27 inches makes no sense. Quite the opposite. Saying you cannot notice 4K at 27 inches is simply false.<\/p><ul class=\"wp-block-list\"><li>The <strong>text definition<\/strong> looks better<\/li><li>The <strong>overall sharpness in games<\/strong> is also better<\/li><\/ul><p class=\"wp-block-paragraph\">The advantage of 32 inches is different: the extra size is welcome for work and lets you organize your workspace better. So, if the monitor will be used for everything, I am firmly on <strong>Team 32<\/strong>.<\/p><p class=\"wp-block-paragraph\">Even so, if you want maximum pixel density, a more compact size, and a very refined experience for desktop use and gaming, the <strong>Asus ROG XG27UCDMG<\/strong> makes a lot of sense.<\/p><p class=\"wp-block-paragraph\">The <strong>Asus ROG XG27UCDMG<\/strong> does not reinvent the segment, since it shares its panel with some very serious competitors, but it does stand out through details that make a real difference.<\/p><p class=\"wp-block-paragraph\">These are its clearest strengths:<\/p><ul class=\"wp-block-list\"><li><strong>Excellent image quality<\/strong> in SDR and HDR<\/li><li><strong>Very good factory calibration<\/strong>, with real room for improvement using a colorimeter<\/li><li><strong>240 Hz OLED<\/strong> with instant response<\/li><li><strong>Very good text clarity<\/strong> for a QD-OLED<\/li><li><strong>Useful extra features<\/strong>: proximity sensor, KVM, PIP, 90 W USB-C<\/li><li><strong>SDR uniform brightness control<\/strong><\/li><li><strong>Anti-flicker for VRR<\/strong> that at least helps<\/li><li><strong>Full PS5 compatibility<\/strong><\/li><\/ul><p class=\"wp-block-paragraph\">Its drawbacks? The usual ones for this technology:<\/p><ul class=\"wp-block-list\"><li><strong>Reflective glossy finish<\/strong><\/li><li><strong>Magenta-tinted blacks under direct light<\/strong><\/li><li><strong>Some flicker with VRR<\/strong><\/li><li><strong>High price<\/strong><\/li><li><strong>No DisplayPort 2.1<\/strong> on this particular model<\/li><\/ul><p class=\"wp-block-paragraph\">With all that considered, my assessment is fairly straightforward: the <strong>Asus ROG XG27UCDMG<\/strong> strikes me as a very solid purchase if you want a high-end 27-inch 4K QD-OLED and value both gaming performance and everyday extras. It is not the cheapest, but it is one of the most complete and well-balanced options in its category.<\/p><p class=\"wp-block-paragraph\">And ultimately, that is exactly what makes it feel so well rounded.<\/p>","protected":false},"excerpt":{"rendered":"<p>The ASUS ROG XG27UCDMG combines the definition of a 27-inch 4K panel with the response of a 240 Hz QD-OLED.
