Hi, all... I'm trying to find anyone who actually owns Z9X media player (preferably with the V6.4.42 FW installed (also newer beta FW (than V6.4.42) is fine)) and is willing to help me find out, if Z9X is actually capable of correct reproduction of HDR10+ encoded stream(s). I currently have three devices claiming they can correctly play HDR10+ encoded streams, but in fact only one can really do that. Please note, that notification "HDR10+" on screen is not proof that the device is actually capable of decoding and applying HDR10+ metadata (my OLED TV Philips 55OLED805/12 (and UHD media player Orbsmart R81) also shows notification that they're playing HDR10+, but in reality they don't (despite what PR material on both claims)). I'm posting here three screenshots from my device capable of correct HDR10+ reproduction (tablet - Lenovo Tab P12 Pro), so you can check and compare with results from Z9X media player. View attachment 10229 View attachment 10230 View attachment 10231 I will be really thankful if you can install on your Z9X app Codec Info, open it, switch to "Video" tab, and find row with title VIDEO/HEVC (OMX.realtek.video.hevc.dec): View attachment 10226 tap on it, and see if on the right part of the screen at the very end is listed this profile: View attachment 10227 If it is there, everything is as it is supposed to be and the device Z9X is very probably capable of correct HDR10+ reproduction - the important part is HEVCProfileMain10HDR10Plus - the rest can be different and at this point is not important. You can double-check with installing second app Device HW info, open it, choose SCREEN tab, and look for HDR row and there should (hopefully) be this: View attachment 10228 Obviously HDR10+ part is crucial, if it is there - everything is as it should be. If it's missing ... well ... both of my OLED TV or Orbsmart R81 don't list HDR10+ on SCREEN tab in Device HW Info, and they are not playing test HDR10+ stream correctly (they are also both missing required profile HEVCProfileMain10HDR10Plus in HEVC HW decoder). If HEVC HW decoder on Z9X is missing HDR10+ profile and SCREEN tab from HW Info only shows DolbyVision. HDR10, HLG (but not HDR10+) - Z9X media player will also not be able to correctly play HDR10+ encoded stream - you can check it by yourself by downloading and playing this HDR10+ stream: original file (size cca 500 MB) - available here ff.de/hdr10plus-metadata-test/ transcoded file with HDR10+ metadata intact (cca 25 MB) - see attachment While watching this test video, it's important to expect that the screen should react to decoded dynamic metadata and do what is showing all the time at the bottom of the screen (video has sound and every time you hear it, the screen should react in a specific way described in the video). So, anyway, thanks in advance to everybody willing to participate in the findings of whether is the Z9X really able to correctly reproduce HDR10+ stream, please post your findings in this thread preferable with the screenshots (positive or negative) - you will help me decide what to do - return Orbsmart R81 (a derivate of Z9X media player) to Amazon and ask my money back or to replace it with Z9X... Thanks again.
