What’s the difference between the U6G, U7G, U8G and U9DG for gaming?

In 2021, Hisense released the U6G, U7G, U8G and U9DG. So, which of these ULEDs is the best when it comes to gaming on PC, PlayStation 5, Xbox Series X, Xbox Series S, Nintendo Switch and other systems?

You can find out in this comparison guide between these four Hisense televisions.

Quick Summary

Out of the 2021 Hisense ULED televisions, the U8G is the best overall gaming TV as it supports HDMI 2.1, 120 frames per second, FreeSync, GSYNC and Variable Refresh Rate. The Hisense U8G also comes with the best HDR brightness output.

The U7G is also a good gaming TV as it supports HDMI 2.1, 120 frames per second, FreeSync and Variable Refresh Rate. Moreover, the U7G has better contrast than the U8G.

The U6G is not suitable for the new PS5, Xbox Series S and Xbox Series S consoles as it only supports HDMI 2.0 and 60 fps. However, it does have the lowest input lag out of this group.

While the Hisense U9DG easily has the best contrast out of this group, it also has the lowest HDR brightness output in addition to highest input lag (unless you use VRR). So, although the U9DG supports the same next-gen gaming features as the U8G, it is a worst gaming TV.

Native Refresh Rate

The U6G has a native refresh rate of 60 Hz, which means that it is capable of displaying videogames at a maximum of 60 frames per second.

The other three sets in this comparison have a 120 Hz native refresh rate. Therefore, the U7G, U8G and U9DG can display up to 120 frames per second at 1080p, 1440p and 4K on the Xbox Series S and Xbox Series X. With the PS5, these TVs can display games at 120 fps at 1080p and 4K.

Adaptive Sync Support

You can find a breakdown of the supported adaptive sync modes for these four televisions below:

U6G:

  • None

U7G:

  • FreeSync
  • Variable Refresh Rate

U8G:

  • FreeSync
  • GSYNC
  • Variable Refresh Rate

U9DG:

  • FreeSync
  • GSYNC
  • Variable Refresh Rate

For PC gaming, FreeSync is mainly used by modern AMD graphics cards while GSYNC is utilized by NVIDIA graphics cards.

For console gaming, Variable Refresh Rate is currently supported by the Xbox Series S and Xbox Series X. The PS5 should also be adding VRR through a future firmware update as well.

These adaptive sync modes are for games that aren’t able to run at a stable and consistent frame rate as they will remove most stuttering and screen tearing.

Input Lag

When it comes to input lag, the U6G has the lowest when you compare the same resolution and frame rate settings, according to tests from RTINGS.com.

The U8G has slightly lower latency than the U7G at 60 frames per second and 120 frames per second. However, the U7G has lower delay than the U8G with variable refresh rate enabled.

Overall, the U6G, U7G and U8G are all considered to be pretty responsive televisions for gaming.

The U9DG, unfortunately, can get noticeable lag in all resolution and refresh rate settings unless you use variable refresh rate. With VRR, it does have the lowest input delay out of the 2021 ULEDs.
