This monitor might look like every other OLED gaming display, but in this video I break down why the Asus XG27AQWMG is actually one of the most interesting developments in monitor tech in a while: it’s using a Tandem OLED panel. I’ve been reviewing monitors for over a decade, and I build my own testing tools, so when something genuinely new lands on my desk, I get properly excited. Tandem OLED stacks four emissive layers (instead of the older three-layer WOLED setup), which lets it push more light with less stress per layer—meaning more brightness and, in theory, better longevity. I go through colour performance (my Spider X2 showed basically 100% DCI-P3 and 82% Rec.2020), accuracy (average delta E under 2), and the big trade-off: WOLED text clarity. It’s improved versus older WOLEDs I’ve tested, but Windows still doesn’t love the RWGB subpixel layout, so picky people will notice fringing. Brightness is also a mixed bag: I saw peaks around 530 nits in a small window, but ABL quickly pulls it down, and 50% window brightness lands around 350 nits. You can enable Uniform Brightness to disable ABL behaviour, but you’re capped around ~320 nits. Gaming performance is exactly what you’d expect from OLED done right: response times are functionally instant (my OSRT tool struggles to keep up), latency is excellent, and the contrast makes dark detail pop. I also cover ASUS’ anti-flicker behaviour, OLED care features like the proximity sensor, and whether this is better value than LG’s own tandem model—or cheaper QD-OLED alternatives.
