Just delete the refresh rates you don't want.

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

I didn't say edit the vrate.

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.

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.

With multiple monitors, the issue is not only the amount of vertical blanking, but all the monitors need to be synchronized so that the vertical blanking happens at the same time, but that's hard to do when all the monitors are different resolutions and refresh rates.

Hi all,

Having some problems using DLDSR to upscale from 3840x2160, in HDR on a Samsung QN85B. Using a 4090 with last version of Game Ready drivers (haven't updated yet as I do it through clean install and haven't prioritised getting around to it)

My active signal resolution defaults and locks to 4096x2160, which DLSDR then adds the 1.78 factor multiplier to. This results in a stretched image in 17:9 aspect ratio. I've tried using CRU to delete out all instances of this resolution but end up with a black screen and have to system restore to fix it

Any advice or assistance would be greatly appreciated, I'm happy to just learn to see in 17:9 lol but would prefer not to if there's a workaround

Hello Mr. Toasty,

I just got an Alienware AW2725DF. Nice QD-OLED with a little bit G-Sync-Flicker. There should be a fix (guru3d.com) for it. They used CRU for the fix. The Problem is: Every change I make with CRU, my Windows/Driver/Monitor just ignores. I got a RTX 3060 Ti and the AW2725 got an DP 1.4 DSC. Do you know a way to help me? I want to change the max Hz from 360 to 350 and the G-Sync-Range/FreeSync-Range to 349.

Greetings

If the changes are not taking effect, that's a driver bug that needs to be reported to NVIDIA.
