Is the LG GX a good gaming TV for the PS5, Xbox Series X and other consoles?

The GX is a new premium television set released by LG in 2020. So how does this television set fare when it comes to playing videogames on the PlayStation 5, Xbox Series S, Xbox Series X as well as other consoles? You can find out in this buyer’s guide.

Quick Summary

The LG is a good television set for the PlayStation 5, Xbox Series S and Xbox Series X. The TV has four HDMI 2.1 ports that will enable next-generation display features like 120 frames per second at up to 4K resolution along with variable refresh rate. The TV also supports Dolby Vision HDR (which is being used by the Series S and Series X) in addition to having extremely low input latency in game mode.

The main drawback is the inconsistent HDR brightness levels. HDR games will look great in scenes that won’t require a lot of lighting. In large areas with a lot of lighting, however, the brightness will look noticeably dimmer.

For older consoles, the GX’s low input should make it a great television set for playing non-HDR games on HDMI systems like the PS4, Switch and Xbox One. You can also connect retro home consoles that uses the composite and antenna/cable inputs.
