H8G vs. U8G: Which is the Better Gaming TV?

Hisense released the U8G in 2021. So, how does the new model compare to H8G, which came out in 2020, when it comes to playing videogames on PC, PlayStation 5, Xbox Series S, Xbox Series X and other systems?

You can find out in this comparison guide between the H8G and U8G.

Quick Summary

The Hisense U8G is a much better television set than the Hisense H8G due to the higher contrast ratios and brighter HDR brightness levels. The U8G model is also the only one to support HDMI 2.1, 120 frames per second, FreeSync, GYSNC and Variable Refresh Rate.

The only advantage the H8G has over the U8G is slightly lower input lag.

Native Refresh Rate

The Hisense H8G is a 60 Hz television, which means you are limited to playing games at a maximum frame rate of 60 frames per second.

The Hisense U8G is a 120 Hz TV. As a result, you can play games at up to 120 frames per second in 1080p and 1440p when using the HDMI 2.0 port if you have a PC, PlayStation 5, Xbox Series S and/or Xbox Series X. If you are using the HDMI 2.1 port, you can play games at up to 120 frames per second in 4K.

Adaptive Sync Support

The H8G does not support any sort of adaptive sync. On the other hand, the H8G supports FreeSync, GSYNC and Variable Refresh Rate.

FreeSync is used by AMD graphics cards while GYSNC is used by NVIDIA graphics cards. Variable Refresh Rate is currently being used by the Xbox Series S/Xbox Series X consoles and is expected to be added to the PlayStation 5.

For the uninformed, adaptive sync will help remove any stutters and screen tearing when playing a game.

Input Lag

The H8G does have slightly lower input lag when compared to the newer TV. However, we consider both to be very responsive television sets when you use the game mode setting as the input delays do not come anywhere close to reaching the 30 ms upper threshold.
