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.
