Based on numbers and the volume of products I’m reviewing, it’s safe to say that OLED is the hot technology in gaming monitors. Although it remains a premium-priced category, the market is responding enthusiastically to the incredible image quality and smooth motion that distinguish the best OLED gaming monitors from other panel types.

Within the broader scope, the best bang for the buck and highest performance are achieved with QHD OLEDs featuring high refresh rates. I’ve looked at many 240 Hz screens that are a competitor’s dream, boasting extremely low input lag and perfect motion resolution. You might say they can’t get better, but a few companies try anyway with displays that run at 360 and 480 Hz. I’m looking at the latter here with a new LG monitor, the 27GX790A. It delivers all the goods with 2560 x 1440 resolution, 480 Hz, Adaptive-Sync, HDR, and wide gamut color. For around $1,000, it promises to be a benchmark for gamers looking to hit high frame rates with the lowest possible input lag. Let’s take a look.
