GIGABYTE MO27Q28GR 27″Glossy WOLED QHD 280Hz Gaming Monitor

The glossy screen is one of the most important reasons to consider the MO27Q28GR.

GIGABYTE uses its RealBlack Glossy surface with an anti-reflective coating to reduce the hazy appearance associated with some matte displays.

This can make dark scenes appear clearer and colours more defined, particularly when gaming in a room with controlled lighting.

Unlike traditional LCD monitors, the WOLED panel controls light at the pixel level, allowing pixels to switch off for deep blacks without conventional backlight blooming.

The fourth-generation panel uses Primary RGB Tandem OLED technology, which GIGABYTE associates with improved brightness and colour performance.

A glossy display can be particularly appealing for gamers who prioritise image clarity and contrast.

However, the ideal coating depends on the environment.

Glossy WOLED: Particularly attractive for vivid images and clear dark details, although direct reflections may still be visible.

Matte WOLED: Can be preferable in environments with difficult lighting or where diffuse reflections are a priority.

If you're comparing GIGABYTE's closely related models, the MO27Q28GR uses a glossy surface, while the MO27Q28G uses a matte surface. Their core resolution and refresh-rate specifications are otherwise closely aligned. GIGABYTE Download Center

At 280Hz, the MO27Q28GR refreshes its image approximately every 3.57 milliseconds.

For comparison:

Refresh Rate	Time Between Refreshes
144Hz	6.94ms
240Hz	4.17ms
280Hz	3.57ms
360Hz	2.78ms

The monitor's 0.03ms GtG response time helps reduce visible pixel-transition blur.

This makes it relevant for fast-paced games such as Counter-Strike 2, Valorant, Apex Legends and Call of Duty, where motion clarity and responsiveness are important.

However, the benefit of 280Hz is greatest when your gaming PC can consistently produce high frame rates.

For players building a competitive setup, suitable gaming mice and PC accessories can complement a high-refresh-rate monitor.

The MO27Q28GR supports three important adaptive-sync technologies:

• NVIDIA G-SYNC Compatible
• AMD FreeSync Premium Pro
• VESA Adaptive-Sync

These technologies help synchronise the monitor's refresh rate with compatible graphics hardware, reducing tearing and improving smoothness when frame rates fluctuate.

This is especially useful in demanding games where maintaining a constant 280 FPS may not be possible.

Tactical Gaming Features

GIGABYTE includes several gaming-focused tools that distinguish the MO27Q28GR from a basic OLED display.

Tactical Switch 2.0: Provides access to gaming-oriented display adjustments, including supported resolution and display-mode switching.

Black Equalizer: Helps adjust visibility in darker game environments.

Crosshair: Provides optional on-screen aiming references.

Ultra Clear: Uses a motion-clarity enhancement technique to reduce perceived blur in supported modes.

PiP/PbP: Supports displaying content from multiple sources using picture-in-picture or picture-by-picture modes.

These features allow players to customise the display for different games and preferences. Some functions may depend on firmware or specific display settings.
