Our take on the ASUS ROG Strix OLED XG27UCDMG 27-inch

The ASUS ROG Strix OLED XG27UCDMG is a 27-inch 4K gaming monitor built on a QD-OLED panel. It pairs 3840 x 2160 resolution at 166 PPI with a 240Hz refresh rate and a 0.03ms gray-to-gray response time, so fast motion stays sharp without the blur of LCD panels. Connectivity covers two HDMI 2.1 ports, DisplayPort 1.4 and a USB-C port, which suits PC and current-gen console setups. It is aimed at gamers who want 4K sharpness and OLED contrast in a desk-friendly size, and it competes with larger 4K OLED monitors on pixel density rather than screen area. Reviewers rate it very highly, though its 250-nit SDR brightness is modest next to brighter LCD rivals.

Questions and answers

Is 27 inches too small for 4K?
No. At 27 inches, 4K works out to about 166 PPI, which makes text and fine detail very sharp. The trade-off is a smaller screen than 32-inch 4K monitors.
Does it work well with a PS5 or Xbox Series X?
Yes. The two HDMI 2.1 ports support 4K at high refresh rates, which matches current-gen consoles. DisplayPort 1.4 is there for a PC.
Is the brightness enough for a bright room?
The 250-nit SDR peak is modest. It looks best in a dim or controlled room, and bright daylight will wash out the picture more than on a brighter LCD.
What is the difference between this and a 32-inch 4K OLED?
The panel technology and 240Hz speed are similar. This one gives higher pixel density in a smaller footprint, while a 32-inch model gives more screen area at lower PPI.
Should I worry about OLED burn-in?
OLED panels can retain static images over long periods. Varying content and using screen-saver features lowers the risk, but it is not zero.
What connections does it have?
Two HDMI 2.1 ports, one DisplayPort 1.4 and one USB-C port. HDCP is supported for protected content.
