27-inch 1440p 500 Hz QD-OLED aimed at high-end competitive gaming. It stands out for outstanding motion clarity, a glossy finish, very good color, 98 W USB-C, KVM, DisplayPort 2.1 UHBR20 and a presence sensor.
PanelQD-OLED
A glossy surface. Reflections tend to look more defined; avoid windows or lights facing the screen.
IMartz verdict
Pros
- Top motion clarity thanks to 500 Hz and the QD-OLED panel.
- Very good sRGB mode, extremely wide color gamut coverage and better text clarity than many WOLEDs.
- Very comprehensive connectivity and extras: DisplayPort 2.1 UHBR20, 98 W USB-C, KVM and a presence sensor.
Things to consider
- High price, especially compared with MAG versions using the same panel and fewer extras.
- Typical OLED VRR flicker, especially visible in gray patterns, loading screens or large FPS changes.
- The glossy finish adds plenty of visual impact, but shows sharper reflections and needs more care.
A good fit if…
- Competitive gamers seeking one of the best high-refresh-rate 1440p OLED experiences.
- Those seeking a genuine 500 Hz, instant response and maximum motion clarity.
- Users who value premium extras such as high-power USB-C, KVM, DisplayPort 2.1 and a presence sensor.
Consider another option if…
- You want the best possible value, because the MAG version with the same panel may make more sense.
- Glossy reflections bother you or your room has a lot of direct light.
- You are very sensitive to VRR flicker and want the best possible G-Sync gaming experience.

Test note · EOTF tracking
TrueBlack 500 and Peak 1000 track the reference quite well, with slightly darker midtones. EOTF Boost brightens midtones and compresses highlights: it increases apparent brightness but loses fidelity. Available brightness decreases as the lit area grows.
