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.
