The LG UltraGear OLED GX7 tops our 27-inch gaming monitor ranking because it is the only OLED in the group, and the listing backs that up rather than just asserting it. The panel is described as WOLED with MLA+, quoted at 240Hz at QHD with a 0.03ms grey-to-grey response, and the spec table lists a 1300:1 contrast ratio alongside DisplayHDR True Black and a 98.5 colour gamut value. Two HDMI 2.1 ports plus DisplayPort are listed, so current consoles can drive the higher frame rates, and the stand is listed as height, tilt, swivel and pivot adjustable.

The two figures worth reading carefully are brightness and evidence. The marketing copy quotes 1300 nits peak while the specification table lists 275 candela per square metre, and those are different measurements rather than a contradiction. At 13 ratings the sample is small for a GBP 399 purchase. Everything here comes from the Amazon listing rather than our own testing.
