Whether you use it for gaming or not, all good TVs are built on the same foundations. You want a 4K resolution, high-enough brightness to overcome glare and make HDR content pop, a relatively high contrast ratio with deep and uniform black tones, colors that find the right balance between accuracy and saturation and wide viewing angles. For video games specifically, you want a TV with minimal input lag and fast motion response, with no blur or other unwanted artifacts behind quick-moving objects.
The updated format promises 'authentically cinematic' use of motion smoothing, and settings that automatically make content look the best depending on your TV and lighting. More than 10 years after the launch of Dolby Vision, the next generation of the HDR format is here, and it aims to do more than just optimize tone and brightness level for different scenes.
