Yes.

how? i don't know how to do this. can u please explain me like for not advanced user?

Just delete the refresh rates you don't want.

I don't know what options Intel has because they keep changing the control panel and I don't use Intel GPUs. As long as it's not display scaling, it should work.

If I am then able to somehow set that 384x128 resolution, then it would use that only for Desktop and keep the full HD resolution for Signal?

Yes. Also the pixel clock might need to be at least 25 MHz for the resolution to be available with DVI or HDMI, but I don't know if Intel enforces that. NVIDIA and AMD do, so you would have to change the totals to something higher like 800x525. The totals won't affect the actual resolution, and the numbers won't matter with GPU scaling.

So it is somehow possible that lower (than 640x480) resolutions show up there. I feel that is not fully reliable, though, and I don't understand when.

Windows will list the resolution if it's the native resolution, but then GPU scaling won't work correctly. That would only work if the display itself can handle 384x128.

Is there a formula for determining the required vertical blanking / maximum bandwidth to keep memory clocks down (amd)?

1920x1080@144 freesync, CVT-RB/CVT-RB2 sets vblanking at 77 lines.
2560x1440@60, CVT-RB sets vblanking at 41 lines. Setting this to 77 allows clocks to come down. This monitor does not like CVT-RB2.

I have a third monitor, 1920x1080@60, that I'm also trying to drive off the gpu. Tried setting it to CVT-RB2 with vblanking at 77 lines, but no luck. Currently have it hooked up via displaylink adapter.

Thanks

i edited vrate to 120 and i still have 144 in games and win cp.

I didn't say edit the vrate.

CVT-RB should be sufficient. CRU won't have any effect with DisplayLink.

Ok so what shoud i do step by step? I don't have avaliable resolutions list.

Honestly, if you can't figure it out, you shouldn't use this program. It's not that hard. Edit the extension blocks. 144 Hz is probably in the DisplayID extension block.

Right, I meant that because I can't achieve low memory clocks with all 3 monitors, I have the 3rd using displaylink at the moment. Unfortunately, this causes all my windows to shuffle after resuming from standby while the usb displaylink reconnects.
