I have never seen a 1080p display advertised anywhere that says it is HDR 10/12 compliant.Ĭare to send me a link to either a 1080p HDR file or 1080p display that is HDR compliant?!? -)" In any event, I am quite sure you would notice a difference playing these files through a devise that supports 10 bit colour depth (is this HDR?) as opposed to one that only supports 8 bit. The HEVC codec allows for 10 bit color depth encodes at 1080p. I have never seen a 1080p video file that is actually HDR compliant (I.E., I would see a notable difference in the colour depth of a 1080p movie being played on a HDR compliant display as opposed to it being played on a non-HDR compliant display" I have yet to figure out what HDR exactly is. Currently, all HDR content is 10-bit, with black mapped at the 64 value, middle gray at 512 and peak luminance at 940/960. The reason HDR standards are 10-bit or higher is because the additional values are needed to prevent the banding which would occur if 8-bit depth was used with an HDR gamma curve. You would have only four shades to work with, but the image would technically be "high dynamic range". For example, theoretically, you could have a 2-bit image (four tone values) that was "HDR" if the correct gamma curve was applied to it. First, dynamic range and bit depth are not related. There are a few misconceptions that I have seen presented in this thread. He tends to believe that when it comes to gaming consoles (Xbox One X and PS4 Pro), that you can get a game to run in 1080p with HDR 10bit / 12 Bit being effective (I.E., noticeable difference to standard 1080p).
My son and I have been having a bit of discussion RE: HDR (primarily 10bit/12bit) and whether it can be applied at the 1080p resolution.
