Our Verdict
LG 27GX790A-B
LG 27GX700A-B
The LG 27GX700A-B is a newer OLED gaming monitor than the LG 27GX790A-B. They have many of the same features, but have WOLED panels from different generations. The 27GX700A-B utilizes the newer RGB Tandem OLED panel, which offers brighter performance and improved color purity compared to the 27GX790A-B. However, the 27GX700A-B is less accurate in HDR because it overbrightens content. The 27GX790A-B is more well-rounded for gaming because it has a higher refresh rate for a smoother feel, and it comes with DisplayPort 2.1 bandwidth to take advantage of modern graphics cards, which the 27GX700A-B doesn't have.
