My Bit Depth is reduced to 6 from 8, If I set monitor resolution to 3440*1440 at 144Hz
This is my HW/SW below
Intel UHD770 with latest driver 30.0.101.1404 / Intel GCC 1.100.3407.0 latest
Mi 34 Monitor Ultrawide screen that supports 3440*1440 Max 144Hz with DP 1.4
MB Asus B660A Gaming Wifi D4 (Support DP 1.4 in back I/O)
Windows 11 with the latest update
Question
1. If I set monitor resolution to 3440*1440 at 144Hz, My Bit Depth is reduced to 6 from 8
But If I change the refresh rate to 120Hz, It works fine and shows with 8-bit Depth in the system PC and Intel GCC tray.
Can anyone give me some answer or explain this problem?
Because Is it limited by HW or something?
2. While I found an article for detail, So I found that We can't set Bit Depth in Intel GCC if use a Display port, It must be connected by HDMI only if you want to set this.
Am I understanding correctly?
Intel will be adding this future as a Display port same as HDMI in Intel GCC?
Thank you
