ASUS ROG Strix OLED XG27AQDMG: Specs, Price, Pros & Cons
A bright glossy OLED with one port specification that decides how you should connect it: the HDMI here is version 2.0, which does not have the bandwidth to carry this panel's full refresh rate.
On a PC that is a non-issue — use DisplayPort and you get everything. On a games console, which outputs over HDMI, you will not reach the headline number on the box. Check that against how you actually intend to use it before reading any further down the page.

Editor’s note
The XG27AQDMG is a bright glossy WOLED, and there is one port specification that decides how you should connect it.
HDMI here is version 2.0. The panel runs 240 Hz at 1440p, but HDMI 2.0 does not have the bandwidth to carry that, so the full refresh rate is available over DisplayPort 1.4 and not over HDMI. For a PC that is a non-issue — use DisplayPort. For a current console, which outputs over HDMI, it means you will not get the monitor's headline figure. Check that against how you intend to use it.
The panel itself is strong. 1,300 nits peak makes it one of the brighter OLEDs here, with quoted contrast of 1,500,000:1, 99% DCI-P3 coverage and 0.03 ms response. It also lists backlight-strobing motion blur reduction, which is uncommon on OLED and gives an alternative route to motion clarity at fixed refresh rates.
The coating is glossy, so blacks look their deepest and a lit room behind you will show. There is a USB hub but no USB-C and no KVM, and the stand adjusts fully including pivot. Variable refresh runs from 40 Hz upward, a slightly wider window at the bottom end than the usual 48.
Buy it for PC gaming over DisplayPort in a room you can control, where its brightness and motion handling are genuinely near the top of this group. Look at an HDMI 2.1 panel if a console is the main source.

The bottom line
The ASUS ROG Strix OLED XG27AQDMG earns a VS Score of 56, a solid mid-pack result among the 102 monitors we compare here. It stands out for a much higher contrast ratio, a much faster response time and much higher peak brightness. Just be aware of the missing uSB-C and the missing picture-by-picture before you buy. Weigh those trade-offs against what matters most to you.
The VS Score is calculated from the weighted specifications above, compared with every other monitor we track — a shortlisting guide, not a substitute for your own priorities. See how we score.
