A:Answer I was the same as you. after much research, the 750D does support HDR but on a limited effect. HDR is best if its on a 10-bit panel and support for wide color gamut. the Sony 750D only had a 10bit panel and does not have a wide color gamut. so it does not have the full HDR experience. however a 4k Blu-ray player and a ps4 pro will register it as a HDR capable TV. Also, one important thing. to enable HDR on the 750D, you need to update its firmware and in the settings you have to set the HDMI inputs to "enhanced". Also, on the 750D, only HDMI ports 2 and 3 support HDR. the rest don't.
