My assumption has been that I can force a given resolution and refresh rate. Since 4k/160Hz/8bit needs less than 48 Gbps with CVT-RBv2 and CVT-RB timings I thought that it would be at least possible to test and see how the monitor would handle it. It's interesting that a few 4k 160Hz monitors with full bandwidth HDMI 2.1 have been released now and all of them that do not have DSC support over HDMI seem to have a 144Hz limit for HDMI 2.1 connections. Any explanation for this would be greatly appreciated. Thank you.

You should be able to. Either the monitor is not actually 48 Gbps, or there's some limitation on NVIDIA's end with EDID overrides. Did you try CVT-RB2? 160 Hz with CVT-RB exceeds 40 Gbps but CVT-RB2 should fit within 40 Gbps. "Exact" would be even lower in this case. What about with NVIDIA control panel custom resolutions?
