All ToX Players support 4K resolution over HDMI port and HDR
HDR stands for High Dynamic Range. Actually refers to a collection of traits that lead to a better overall image. On a TV that supports HDR, bright parts of an image will appear brighter than before, while dark parts of an image will be darker than on older TVs. This gives TV shows and movies better contrast and can make some scenes feel more real. HDR also expands the range of colors your TV can display beyond what you’re used to seeing on previous generations of TVs.
