Update 10/05/2020: We remeasured the input lag outside of Game Mode following a firmware update. The input lag is slightly lower.
Update 09/21/2020: A few users have mentioned that the 43 inch model has an issue with brightness when Game Mode is automatically enabled. This appears to only affect the 43 inch model, and it seems like disabling and then reenabling Game Mode fixes the issue.
Update 07/22/2020: We made a mistake in the way we measured the input lag at 4k @ 60Hz + 10-bit HDR. We remeasured the input lag and updated the text.
The Samsung TU8000 has a remarkably low input lag at all resolutions with Game Mode enabled. It’s higher with motion interpolation enabled, but overall, it responds quickly to your inputs. You can only get low input lag at 4k @ 60Hz with chroma 4:4:4 when it’s in ‘PC’ mode, but the TV can usually detect when a PC is connected and switches to ‘PC’ mode automatically.
There’s an Auto Low Latency Mode, which automatically turns on Game Mode when the TV detects a game being launched from a compatible device. To use it, Game Mode Auto and CEC must be enabled.
