I’ve been unable to get the HDMI output to recognize my TV as a HDR display. Seems not to matter which resolution, so that rules out a bandwidth limit, and I’ve tried the various emulation methods.
Worth noting, I’m currently running with only the HDMI output, and nothing connected to the DP output. I have a 4k HDR monitor around but not in use in case it requires the DP display to specify a HDR signal?
Also worth noting, I’m using HDMI cables specc’d for HDR and have had no trouble running 4k HDR from PC → TV via these HDMI cables. The DP cable going to the repeater is 1.4.
Any tips on getting the HDMI to output HDR would be much appreciated.
