My question is about bandwidth limits and setting custom resolutions and refresh rates to achieve a better result than the default available on certain monitors.

My situation is with a Samsung Odyssey G7 2020. This monitor is 2560x1440 @ 240Hz DisplayPort 1.4 powered by a 3080Ti.
1440p @ 240Hz with 10 bit HDR bandwidth needs exceed DP 1.4 capabilities. The next lowest option in NVCP is 144Hz. I believe the max limits should be about 205Hz for 10bit 1440p.

If I set a custom resolution with the only changing factor being the refresh to lets say 200Hz, will I be getting uncompressed 10bit HDR 1440p @ 200Hz or will there be some form of compression still happening since I am above the next lowest default in NVCP of 144Hz?

@Inle Could you possibly shed some light on this?

Anybody have a clue?

@Inle @W1zzard you two are the ones I figured could best answer this.

Is there a tool or something in NVCP that could show me if DSC is enabled or if the signal is uncompressed?

The information in GPUZ couldn't quite tell me the answer I was looking for, I did learn its capabilities which was helpful in knowing it's limits.
What I'm looking for really is just to know whether the signal is uncompressed or using DSC with an easy indicator ie; DSC Mode - on or off

I wonder if anything from the VESA test tools site could tell me.
