WIndows/Nvida HTPC setting for 2019 Samsug (Q70R) with HRD and without?
 
Laymen here trying to figure out the isims of implementing HTPC setting with HDR 4k Tv.

My current thinking is for normal windows SDR I should NOT select the HD option in the Windows HD Color settings. Nvidia options set to 3840X2160 Native, 60Hrz, 32 bit/8bpc/RGB/full. TV set to PC which I believes gives 4:4:4 and input signal plus and HDMI CEC enabled. Graphic card connected to TV for visual and Receiver for audio

THE ? is there a way to keep above settings and at the same time watch full 10bit color HDR 4k movie files , preferably with SVP, and if not how do you guys ensure you are watching movie files in full 4k HDR 10bit glory. What is the best way to use the computer for SDR and HDR content.

What standard is your TV supporting over HDMI ports? What about the video card?

Note that HDMI 2.0 doesn't support the bitrates needed for RBG 4:4:4 10bit HDR and the TV's that support HDMI 2.1 are... big league boys price-wise.

In my experiments with my HTCP having nvidia GeForce GT730 video card (HDMI 1.4) and my Vizio PX65-G1(4K HDR HDMI 2.0) I can get only those combinations:
1080p, 60Hz, 12 bit RGB / 4:4:4
1080p, 120Hz, 8 bit RGB / 4:4:4
4k, 60Hz, 8 bit 4:2:2


Note that most 4K media is only 4:2:0 anyway...


I have tried my Quadro P620, but all my miniDP adapters are doing only 1080p 60Hz (165MHz BW passive adapter) or at the most 4K 30Hz (adapter-cable with HDMI 1.2a/1.4)... I have ordered an active 4K/60Hz adapter (600 MHz BW), waiting and see how that goes.
