Specs
Pros
Pro No input lag issues
This is one of the best TVs that can be used for gaming as it manages to deliver absolutely excellent motion control with no noticeable motion blur problems. Input lag measures around 20 ms in FullHD, 4K or 4K+HDR modes. This means that the action on the screen will not be blurred out nor will it lag behind the actual controller input.
Pro Superb contrast and color reproduction
The Samsung KS800 does not disappoint when it comes to picture quality. The TV has a 10 bit panel with excellent color gamut coverage, meaning that the picture will look detailed and colors will look natural without any banding issues, especially if HDR content is displayed. Contrast and color uniformity is also excellent for a LCD TV making it a good choice for very dark rooms, as no backlight blooming will be visible.
