Hi there! What a fantastic guide. Must have taken ages with all the superb formatting. Thanks a lot!
I've got a couple of questions that I hope somebody can help me with. The first has to do with getting the most out of a monitor by using all of the cable bandwidth:
I’ve considered monitors like the LG 38GL950G-B where the max performance would push it past cable limitations, meaning you’d have to scale down refresh rate in order to get full RGB / 4:4:4.
Normally I see articles saying that in order to stay within cable limitations at full RGB, you’d have to lower the refresh rate to something like 120/144/160hz or other standard refresh rates, but then some performance would be lost.
Couldn’t you just set a custom resolution in nvidia control panel that maximizes cable bandwidth, and squeeze every possible refresh rate out of it?
For this monitor, 8bit full RGB would maximize DP 1.4 at 159hz, and 10bit at 129hz according to the calculator.
I’m not an expert though, so I don’t know if anything would get in the way of it, forcing you to use one of the standard refresh rates I always see mentioned.
Would it work, and would anything need to be sacrificed with a custom resolution / refresh rate, like VRR?
I also wanted to ask about DSC: where does it need to be supported? Is it both GPU, cable, and monitor? And could a monitor be firmware updated to support it?
I hope anyone knows. Thanks!
