GIGABYTE G27Q26 vs ASUS ROG Strix OLED XG27AQDMES Comparison
ASUS ROG Strix OLED XG27AQDMES
The ASUS ROG Strix OLED XG27AQDMES is the better overall monitor for image quality and gaming, thanks to its QD-OLED panel, 0.03ms response time, 1,500,000:1 contrast ratio and 99% DCI-P3 coverage. The GIGABYTE G27Q26 has the advantage in refresh rate at 275Hz versus 240Hz, plus 500 cd/m² peak brightness, HDMI 2.1 and useful features such as Black Equalizer. ASUS also adds Motion Blur Reduction, Shadow Boost, Dynamic Crosshair and other gaming controls. For competitive gaming at the highest refresh rate, choose the G27Q26; for OLED picture quality and a more premium gaming experience, choose the ASUS XG27AQDMES.
The G27Q26 uses a conventional IPS panel with Edge LED backlighting, while the ASUS ROG Strix OLED XG27AQDMES uses a Samsung QD-OLED panel with self-emissive pixels. Both are designed for gaming and offer QHD resolution, but ASUS has a much higher listed 1,500,000:1 contrast ratio compared with 1300:1 on the GIGABYTE.
The G27Q26 has the higher refresh rate at 275Hz, while the XG27AQDMES reaches 240Hz. However, ASUS lists a much faster 0.03ms response time compared with 1ms on the G27Q26. Both support AMD FreeSync and NVIDIA G-Sync, while ASUS adds Motion Blur Reduction, Shadow Boost, Dynamic Crosshair, FPS Counter, AI Gaming Features and GameFast Input.
The ASUS monitor has the OLED advantage with 1,500,000:1 contrast and 99% DCI-P3 coverage, while the G27Q26 offers higher listed peak brightness at 500 cd/m² and wider 125% sRGB coverage. ASUS supports HDR10 and DisplayHDR 400 True Black, whereas GIGABYTE lists HDR10. For deep blacks and OLED contrast, ASUS is the stronger specification.
ASUS provides a broader set of premium features, including gamma and color adjustment, OLED Care, custom heatsink, desktop and monitor management software, Aura Sync and a proximity sensor. The G27Q26 still offers 130mm height adjustment, swivel, 90-degree pivot and portrait mode, while both support VESA 100 × 100mm mounting.
