NVIDIA does not currently support DSR with display stream compression (DSC). In theory, 3840x2160 @ 144 Hz at 8/10 bpc should be possible without DSC with HDMI 2.1 at 48 Gbps, but not with DisplayPort. Were you using DisplayPort or HDMI with the M32U? Export a file for each monitor using CRU and post them here.

I can not raise the frequency above 75 hertz, through the graphics driver or nvidia amd writes that the display is not supported, through the CRU can not be added due to the fact that the display has already entered 4 profiles with a hertz and their CRU can not change in any way, in this case, how can you raise the hertz frequency or it's display locked from the factory to increase the hertz?

P.S Freesync was disabled when trying to overclock

I'm not sure what you're saying. You mentioned several things that have nothing to do with each other. Export a file using CRU and post it here.

M32U was with DP cable and the TV has only HDMI 2.1

I dont have the M32U anymore but i have make some screenshots from cru before.

4k 144hz 8bit were great for me with DSR. But when iam set this DSR is not showing directly. I can try to restart or using cru reset64.exe.

edit: i have test 100hz, 4.2.0, 8bit but DSR is not showing :-(

The thing is I try to add or edit a hertz frequency higher than 75 hertz, but the hertz profiles display in Windows 10 just does not change, just static display 4 profiles and it is 50/59/60/75 hertz, CRU settings are just ignored

I need you to export a file for the TV using CRU and post it here. 4:2:0 probably won't work with DSR either. Try RGB and YCbCr 4:4:4.

What GPU? You said NVIDIA AMD. You should read the part about pixel clock limits in the first post.

I have an RX 470 GPU and the latest amd driver at the time of writing this post, also the monitor and GPU are connected via HDMI 1.4, hence I need to add an extension unit for hdmi manually which would increase the frequency limit from 165mhz I understand correctly?

i have upload the file here: https://drive.google.com/file/d/1Rswxx0p...sp=sharing

I have also test Rgb and 4:4:4 before i set 4:2:0
Thanks for your help.

That's not the full EDID. The extension blocks are missing. Does CRU not show the extension blocks?

No, it already has an HDMI data block. "AMD/ATI's driver also listens to the maximum TMDS clock in the "HDMI support" data block. Make sure it's enabled and set to 340 MHz."
