Price and rating as shown on Amazon when we collected them. Both change.
The ASUS ROG Strix XG27ACDNG is the sixth entry in this guide and the genuine OLED of the set: at £548.99 it sits £51 below the 49-inch Gawfolk at £599.99, whose own feed lists 'Display Type: LED' and 'VA Panel'. The ASUS spec table says OLED twice, under Display Type and Display Technology, and pairs it with a 360 hertz refresh rate and a 0.03 ms response time.
Its own listing disagrees with itself in two places. The product name and the Screen Size field read 27 Inches, while the very first bullet describes a 26.5-inch QD-OLED. Image Brightness is given as a bare '1000' with no unit at all, and Contrast Ratio as '> 400:1' — a figure far below what OLED listings usually quote. Everything on this page is taken from the Amazon listing, not from any testing of ours.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Once you go OLED it is very difficult to go back, The colour accuracy and overall screen quality is miles ahead of any other monitor on the market, with a 360Hz refresh rate you are getting the most out of your FPS - If your not consistently hitting these frames then this won't matter so much. I did a lot of research before pulling the trigger on one of these and this is one of the best value for money options for quality and spec in it's size, there may be better if your sizing up or looking at curved options. After about a year of daily use, sometimes active for up to 8 hours, I've yet to see any burn in, although it does have regular pixel refresh built in, and highly recommend power saving screen off after 5 minutes max”
Verified purchase“I bought this following a return of an MSI MPG 271QR X50, which had terrible issues with brightness and washed out colours even after hours of calibration and messing with settings.The XG27ACDNG was set up and running in under 20 minutes, with brightness and colour accuracy matched with my other monitor as near as possible.Packaging is fine, but non-descript, but it's clear the care was placed in other areas. The build quality of the monitor is fantastic, and feels sturdy and the monitor looks great with nice looking RGB on the back that is not over the top. The OSD settings are easy to use and expansive. There is little in the way of AI settings which I am thankful for as they never really tend to help the picture overall.The monitor can get incredibly bright, and while it does have instances where ABL can kick in, while gaming this hasn't been an issue so far.The real sweet spot of 1440p shows, as coming from a 4k monitor I was finding that my 4070super was struggling with recent games such as 007 First Light and Forza Horizon 7 to maintain a good framerate without the use of multiple DLSS Features. the 360hz refresh rate is crisp, and can provide a built in framerate counter that isn't massively intrusive.The monitor comes with a nice fabric pouch that contains all the cables needed to connect to a PC, including a 5gbps USB B to A cable to get the best from the built in USB hub which provides enough power and bandwidth for a capture card to run through the monitor without issue, and has 3 USB ports and a built in KVM if you require that.All in all, I couldn't be happier with this monitor and would easily recommend it to anyone looking for a great quality QD-OLED panel.”
