Gamers on the lookout for a new high-speed gaming monitor will be pleased to note that the 27-inch LG UltraGear 27GX790A-B gaming monitor is now available for an all-time low price. The QHD OLED gamer sports 480 Hz refresh rate, and a peak HDR brightness of 1,300 nits.

Gamers looking to upgrade their monitor will likely have LG's UltraGear range on their radars. Those eyeing a 27-inch ultra-high-refresh rate gaming monitor will be pleased to note that the well-reviewed 27GX790A-B is now available with a substantial discount on Walmart, dropping its price down to a lowest-ever of just $468.

A lower-end variant with a peak 280 Hz refresh rate is also on sale, priced at around $383 on Amazon.

This 26.5-inch gamer sports a beautiful OLED panel with a resolution of 2560 x 1440. While its resolution is nothing special, the LG 27GX790A's refresh rate of a whopping 480 Hz makes it a solid choice for fast-paced gaming and competitive e-sports titles.

With a peak brightness of 1,300 nits in small areas, HDR performance should be simply excellent, as corroborated by TomsHardware's detailed review of the monitor. However, full-screen brightness peaks out at only 250 nits, which necessitates a controlled lighting environment for the best experience.

TH also found that the panel covers an impressive 96% of the DCI-P3 color gamut with acceptable color accuracy out of the box, which can be improved substantially with some calibration.

Being an OLED gaming monitor, there were no complaints whatsoever regarding the UltraGear 27GX790A-B's input lag or response times. VRR is also well-supported, as is G-SYNC compatibility. 

That said, there is some noticeable VRR flicker, which is common with OLEDs. This is easily fixable, however, simply by setting a frame cap, or by turning off VRR when gaming.

The gaming monitor features a striking design that is typical of LG's UltraGear lineup.

The I/O on offer is pretty decent, detailed below:

  • DisplayPort 2.1
  • Dual HDMI 2.1
  • 3.5 mm audio
  • USB 3.0 (upstream), dual USB 3.0 (downstream)

Ergonomic adjustment capabilities include 5 to 15-degree tilt, 30-degree swivel, 90-degree pivot, and 110 mm or 4.4 inches of height adjustment.
