It’s nearly impossible to find a bad OLED monitor. They all have perfect blacks and infinite contrast. The 27-inch QHD category is particularly rich in options, all of which are excellent. Only a few tiny elements separate the excellent from the really excellent.
LG’s 27GX790A stands out in a few areas. It’s brighter than most with 415 nits for SDR and 763 for HDR, the highest I’ve seen from a 27-inch OLED screen. It has two levels of variable brightness and constant brightness too. And it ties my record for lowest input lag of any screen I’ve tested with 10ms. It’s only equaled there by Philips’ 27M2N8500. The deciding factor there is that the Philips tops out at 360 Hz, so when you get that next-gen PC, the 27GX790A will have 480 Hz to offer.
Image quality and gaming ability are accompanied by a premium build, a full feature set and plenty of flexibility. The 27GX790A is one of the few monitors with adjustments for sRGB and HDR modes with color temps and brightness controls. Though I noted room for accuracy improvements out of the box, it calibrated to the same high standard as any premium OLED.
For $800 at this writing, the LG 27GX790A is priced competitively and has standout features and performance. If you have the budget, and plan to keep your video hardware on the bleeding edge in the future, this is a monitor that should be on your shortlist.
