The LG UltraGear 27GX790A-B monitor combines image quality and gaming comfort! With its large 27-inch 2.5K screen, OLED panel, 480 Hz frequency and ergonomic stand, it guarantees high image quality and perfect comfort.

High image quality
The OLED display on this LG screen offers colours with a vibrancy that's taken to a whole new level. With a standard brightness of 275 nits and a maximum brightness of 1300 nits, this screen keeps visuals bright and vibrant. Certified to VESA DisplayHDR True Black 400, this LG monitor brings all scenes to life, whether bright or dark, thanks to lifelike detail with a 1.5M contrast ratio and 98.5% typical DCI-P3 colour coverage. What's more, with an anti-glare surface and Flicker-Free, Discomfort Glare Free, and Low Blue Light technologies, this LG screen offers enhanced eye comfort.
A clear, fluid image
Enjoy a particularly fluid display with a maximum display frequency of 480 Hz (via DisplayPort 2.1) and an ultra-fast response time of 0.03 ms! With a response time of 0.03 ms (GtG), which reduces the inverted image process and gives objects a clear rendering, enjoy gaming with smoother movements and surreal visual fluidity.
What's more, with G-SYNC Compatible certification and FreeSync Premium Pro technology, enjoy a smooth, fast gaming experience with no screen tearing. This monitor has also received VESA ClearMR 21000 certification, guaranteeing that you'll see movement with the same sharpness as still images, with motion blur during gaming considerably reduced.
Ergonomic and elegant
Enjoy a sleek, almost edge-to-edge four-sided design with backlighting for a resolutely Gamer look! This LG monitor also benefits from a fully adjustable base offering rotation, tilt, height and swivel. The clutter-free L-shaped stand and wide-range rotation adjustment are designed to maximise space on your desk and minimise unusable areas.
