I have HDR enabled on the PC and the projector and a quality 4K complaint HDMI ran directly from PC to projector. I also have a GTX 1050 ti video card with resolution set at 3840x2160, and just installed the latest driver. I just installed the latest patch for your software. I also downloaded a free trial of a competitor's software, and the file plays fine with that software. However I truly love the interface of Powerdvd and really want to get this to work. Can someone please help me figure this out?
