Our Verdict

LG 27GX790A-B

LG 27GX790B-B

The LG 27GX790A-B and the LG 27GX790B-B are both high-end OLED gaming monitors, with a few differences. The 27GX790B-B uses an RGB Tandem OLED panel that allows it to get brighter and display more vivid colors than the older panel of the 27GX790A-B. They each have high refresh rates, but the 27GX790B-B has a dual-mode feature to raise it to 720Hz with a 720p resolution, giving it more versatility for playing different types of games. The 27GX790B-B even offers a more accurate sRGB mode, which is worth considering for content creation.
