You're competing at a level where 240Hz isn't enough. Your opponent sees the flick before you do because their panel refreshes faster and their pixels switch before your eye finishes tracking.
The Q27G4SD is built for that gap. 26.5-inch QD-OLED with anti-reflection coating. 360Hz over DisplayPort 1.4 (with DSC) or HDMI 2.1 (with DSC). 0.03ms GtG. That's the fastest response AOC puts in a QD-OLED panel, and it means zero perceptible smearing at competitive frame rates.
Contrast is 1,500,000:1 because every pixel is its own light source. No backlight bleed. True blacks. 1000 nits peak in HDR (3% APL), DisplayHDR True Black 400 certified. 99% DCI-P3 and 100% sRGB with Delta E under 2.
The stand goes where you need it: 130mm height adjustment, full pivot, swivel, and tilt. Two HDMI 2.1 ports plus one DP 1.4. Flicker-Free and Low Blue Light for the long sessions after 9pm.
