I am sorry if these questions have been asked and answered before; I found answer to similar type questions but I could not fully grasp most of them; my understanding of PQ settings is very juvenile. I would be very grateful if someone here could guide me on the following four Q5Pro PQ settings.
My TV is model LG 65UH650T http://www.lg.com/my/tvs/lg-65UH650T
65inch, 4K, HDR10 (Pro). The LG website claims that the display refresh rate on this TV is 100hz. It also has 4K up-scaling capability.
Here are my four Q5 PQ settings questions with the relevant snapshots attached:
1. Display format. Default was 1080P 60Hz. Should I change it up to 2160 since my TV already has up-scaling capability? If yes, which refresh rate should I use? MY LG TV has a claimed refresh rate of 100hz.
2. HDMI Auto Adaptation. Default was off.Should I leave it off?
3. Video Color Space & HDMI Deep Color. Default was YCbCr444 8BitI changed it to YCbCr444 10Bit since the TV is HDR10 capable. Is this correct?
Or should I change it to another selection such as YCbCr420 10Bit? I have no clue what the differences are between all these.
4. Display Advanced Options - TV HDR ModeDefault was AUTO. I changed it to HDR10 since the TV is HDR10 capable. Is this correct?
If yes, I guess I also need to go into the LG TV settings to turn on HDMI deep color for that HDMI input.

Thank you for your help.
