Our take on the ASUS ROG Strix OLED XG27UCDMG

The ROG Strix OLED XG27UCDMG is a 27-inch 4K QD-OLED gaming monitor with a 240Hz refresh rate and a 0.03ms response time. Its quantum-dot OLED panel delivers near-instant pixel response, deep blacks and full 10-bit color, which puts it ahead of most 4K IPS and VA monitors on motion clarity and contrast. It suits competitive PC and console players who want 4K sharpness and high frame rates in one screen. The trade-offs are typical of OLED: modest SDR brightness and the risk of burn-in with static content.

Questions and answers

Is 240Hz worth it at 4K?
Yes if your GPU can push high frame rates at 4K. The 240Hz panel and 0.03ms response make motion much clearer than 60Hz or 144Hz 4K screens.
Does it work well with a PS5 or Xbox Series X?
Yes. The two HDMI 2.1 ports support 4K at high refresh rates, so current consoles can use their 120Hz modes.
Is the brightness enough for a bright room?
The 250-nit SDR rating is on the low side. It is best in a dimmer room or with curtains drawn; HDR highlights go brighter than the SDR figure.
Should I worry about OLED burn-in?
There is a risk with static elements like HUDs, taskbars and icons. Use the built-in OLED care features and vary content to reduce it.
What connections does it have?
Two HDMI 2.1 ports, one DisplayPort 1.4 and one USB-C port, plus HDCP support for protected content.
Is 27 inches too small for 4K?
No. At 166 PPI the image is very sharp, but text and UI can look small, so plan on display scaling in your OS.
