Asus has introduced some of the best OLED gaming monitors in recent years, and with each generation, it makes incremental improvements in performance, features, and technology. Its latest panel type is Tandem RGB Stripe, bringing higher brightness, a wide color gamut, sharper imagery, and lower power consumption.
The latest ROG Swift display to hit my test bench is the PG27UCWM. It’s a 27-inch 4K panel with 240 Hz (480 Hz in FHD), HDR10, Dolby Vision, DisplayHDR 400, and Adaptive-Sync. Let’s take a look.

I’ve reviewed a few Tandem RGB Stripe OLEDs of late, most recently, Asus’ 32-inch version of this screen, the PG32UCWM. There’s no denying the extra sharpness that this tech brings. Though I never saw much color fringing around text as discussed online, these new panels are clearly sharper than single-layer OLEDs. By sandwiching two layers and making the pixels’ physical shape narrower, you get more clarity, more color, and more brightness at a given wattage. And by driving the panel less aggressively, its lifespan is extended.

The PG27UCWM’s color volume is greater than that of single-layer OLEDs but not quite as large as that of Quantum Dot displays. I measured just over 102% coverage on my sample, whereas you’ll get closer to 110% with a QD monitor. Asus includes factory calibration with each monitor, and you can find that stored in firmware and accessed through the comprehensive OSD.
Peak brightness is just under 500 nits when measuring a 25% window pattern with uniform brightness turned off. That number holds for both SDR and HDR content. The PG27UCWM supports HDR10 and Dolby Vision, with VESA DisplayHDR 400 certification. Asus’ TrueBlack Glossy screen coating keeps reflected light from spoiling those deep black levels.
