Gigabyte MO27Q28G
27-inch QHD 280 Hz OLED with a 4th-generation Tandem WOLED panel, matte finish, very good HDR brightness for OLED and fairly comprehensive connectivity
PanelTandem WOLED
A matte surface that diffuses reflections. Light can spread over a larger area; the finish does not eliminate reflections completely.
IMartz verdict
Pros
- New-generation Tandem WOLED panel with clear brightness and color improvements over previous WOLEDs.
- Virtually instant response and 280 Hz
- Very competitive price against other Tandem OLEDs, especially around €500-550.
Things to consider
- Reduced-bandwidth HDMI 2.1, with 4K limitations on PS5 and 4:2:0 chroma.
- Typical WOLED banding / DSE.
- Needs a firmware update to fix HDR.
A good fit if…
- Users who want a fast, bright 1440p OLED at a relatively balanced price.
- Competitive gaming and single-player HDR games on PC.
- Modern OLED with a matte finish
Consider another option if…
- You dislike a matte finish
- Refresh rate is your priority; 360 Hz QD-OLED models are available at this price.
- You cannot tolerate even a little DSE / banding.

Test note · EOTF tracking
With F06 firmware, HDR mode keeps midtones close to the reference but darkens shadows. HDR Game and HDR 1500 Peak brighten some midtones and compress highlights, producing a brighter but less faithful image. The high peak is reserved for small details and falls as the lit area grows.
