LG 27GX704A-B vs ASUS ROG Strix OLED XG27AQWMG

Two 27-inch 1440p WOLED monitors from the same generation, close enough on panel that the ports decide it.

The ASUS uses a Tandem WOLED, two emissive layers stacked, which is how it reaches 1,500 nits peak against the LG's 1,300. Both are large figures by OLED standards, where 1,000 nits was the ceiling until recently, and the gap matters less in practice than on paper: the ASUS is brighter in small highlights, and neither looks flat in HDR. ASUS also quotes marginally wider colour, 99.5 per cent DCI-P3 against 98.5, and a faster refresh, 280 Hz against 240.

The LG's case is the back panel. It has two HDMI 2.1 inputs to the ASUS's one, plus a USB hub the ASUS does not have. If a console and a PC both live on this monitor, that second input is the difference between swapping cables and not. Neither has USB-C and neither has a KVM, so a laptop still needs its own dock.

Everything else is shared: 110 pixels per inch, 0.03 ms response, a quoted 1,500,000:1 contrast, 10-bit colour, a glossy coating, and full height, tilt, swivel and pivot adjustment on a 100 mm VESA pattern.

Buy the ASUS if this is a PC-only desk and you want the brighter, faster panel. Buy the LG if a console shares the monitor, or if you want somewhere to plug a keyboard and a dongle. At 110 ppi neither is a text monitor first - these are gaming panels that happen to be very good at film, and both will show the same glossy reflection of a window behind you.
