Alienware AW2725DF

i'd do a 27gx790a-b or aw2725df the LG is 480hz and matte woled while the Dell is 360hz glossy qd-oled, meaning it'll have better colour vibrancy.

if you want 27 inches there's AW2725D (360hz) or AW2725DF (280hz)

The AW2725DF is likely the best spec-wise out of the lot, with a generous burn-in warranty & the best factory calibration (it even comes with its own calibration sheet). ... If you're playing in a dark room though, that's definitely the panel I'd recommend. I've had it for 18 months now, and there's *zero* sign of burn-in, even on test patterns, despite regular use at high brightness with bright crosshairs in the centre of the screen.

A lot of the QD-OLED's are calibrated at factory with very accurate colors out of the box. Check out AW2725DF for an example.

I originally had my mind set on the AW2725DF for the 360HZ

If you're willing to spend a bit more, you can get the AW2725DF for around £540, i got it this week and absolutely in love with it

AW2725DF maybe. It's a 27 inch 4k 240Hz OLED. The new 27 inch 4th gen panels. In the US it's quite a bit cheaper than the competition because it's only DP 1.4. On my monitor that uses the same panel, the text fringing issue is basically non existent now.
