LG A1 vs. LG BX: Which is the Better Gaming TV?

The A1 is a new entry level OLED released by LG in 2021. So, how does it compare LG’s 2020 entry level BX OLED when it comes to playing videogames on the PC, PlayStation 5, Xbox Series S, Xbox Series X and other systems?

You can find out in this comparison guide between these budget friendly OLEDs.

Quick Summary

For the most part, the LG BX is a better television set for gaming when compared to the LG A1 as the BX is the only of these two TVs to support HDMI 2.1, 120 frames per second, FreeSync, GSYNC and Variable Refresh Rate.

The BX is also slightly brighter than the A1 when you are playing HDR-enabled game. With that said, the HDR brightness is unimpressive for both of these TVs when compared to the higher end OLEDs.

The lone advantage of the A1 is that is features lower input lag than BX.

When it comes to HDR brightness, the older BX is a slightly brighter than the A1.

According to tests conducted by RTINGS.com, the BX can reach 450 nits when playing an HDR-enabled videogame using the TV’s game mode setting while the A1 can reach 444 nits.

To show off HDR, we recommend getting a TV that can output a minimum of 500 nits of HDR brightness. So, both of these OLED televisions struggle in this department, especially if you are planning to spend a majority of time playing a game in a well-lit room.

Native Refresh Rate

The LG A1 has a native refresh rate of 60 Hz as it can output a maximum of 60 frames per second.

The LG BX has a higher native refresh rate of 120 Hz as it is capable of outputting a maximum of 120 frames per second.

Adaptive Sync Support

As for adaptive sync, which helps with eliminating screen tears and stutters in games, the BX supports FreeSync (for PCs with AMD graphics cards), GSYNC (for PCs with NVIDIA graphics cards) and Variable Refresh Rate (for Xbox Series S, Xbox Series X and, eventually, PS5).

On the other hand, the A1 does not support any of the three adaptive sync features.

Input Lag

The A1 does have lower input lag when compared to the BX in the same resolution and refresh rate combinations.

However, we still consider the BX to be a pretty responsive television set when it comes to gaming.
