Question Gigabyte AD27QD: RGB? YCbCr422? YCbCr444? 8 bpc? 10 bpc?

[King Mustard]

I have a Gigabyte AD27QD, which contains a 144 Hz 1440p IPS panel.

As it's a 144 Hz monitor, I've used ran at that refresh rate since I bought it a few months ago.

However, I noticed that, in the NVIDIA control panel, whilst I always get various options in 'Output color format' (RGB, YCbCr422, YCbCr444) and 'Output dynamic range' (Full, Limited), I only get the 8 bpc option for 'Output color depth'.

My questions are:

1. Which 'Output color format' should I be using?
2. Should I switch from 144 Hz to 120 Hz in order to choose 10 bpc? (it's a 8-bit + FRC panel)

Always use RGB full range for computer monitors.

8 bpc vs 10 bpc really makes no difference itself, but you won't be able to use HDR unless you select 10 bpc.
