LG has just challenged all manufacturers of e-sports monitors! The UltraGear 27GX790B model has gone on pre-sale, boldly combining two worlds for the first time: OLED picture quality with a record refresh rate of 720 Hz! This is equipment designed to settle the eternal debate about whether for “serious” gaming it's better to choose the fastest TN panel or a beautifully glowing OLED.
720 Hz and Dual-Mode: No More Compromises
The most interesting feature in the new UltraGear is the Dual-Mode function. LG understood that gamers need different parameters for playing AAA games such as The Witcher or Cyberpunk 2077, and different ones for Counter-Strike or LOL. Instead of buying two monitors, we get one that switches between two modes:
QHD (2560 x 1440) at 540 Hz – for those who want the best image quality
HD at 720 Hz – a mode designed for professional e-sports.
The OLED matrix with an almost instantaneous response time of 0.02 ms (GtG) makes motion blur virtually non-existent. Regardless of what is being played, the image remains razor sharp.

Tandem OLED
The biggest issue with OLED screens has always been their low brightness. LG has solved this with the Primary RGB Tandem OLED technology. It’s a multi-layered panel structure that allows for an impressive 1500 nits of brightness. As a result, the HDR effect finally "hits" as it should, and the monitor should easily cope in bright rooms. On board, we’ll find DisplayPort 2.1, which is essential for refreshing at 720 Hz.
Availability and Price
The LG UltraGear 27GX790B monitor is priced at 3599 PLN (around $990 in the US). Considering that it is currently the fastest OLED panel on the market, the price seems to be set very aggressively for its launch.
