So how do I get Windows to show it? With my four slots, I guess I could do 120.000 (default), 143.856 (24FPS video), 89.910 (30FPS video) and something else, but that's a bit cumbersome. Maybe the absolute highest my screen can go? How would I find that out? It's a 144HZ screen, but how much of an upper bound is that?

EDIT: And do games with a 120FPS cap, for example, output EXACTLY 120.000FPS, or 119.88FPS? What are they expecting the display to be? Or does it depend on the game? If they output 119.88 then I can just set my display to that.

The display on this laptop doesn't seem to be G-SYNC, so unless I'm wrong, I'd need to set exact refresh rates for everything.

Windows doesn't have a way to list multiple refresh rates that round to the same value. Some laptop screens can be overclocked. You would have to try and see, but I wouldn't bother since it already supports 144 Hz.

Game frame rates are not exact and can vary depending on load. You can't make the refresh rate match the frame rate perfectly without VSync or FreeSync/G-SYNC. Even if the game's frame rate was perfectly stable and the refresh rate happened to match exactly, there's no guarantee the frame would be updated between refreshes, so you would have a perfect line of tearing that never moved.

Thanks for CRU developer. I feel so fluent.

Hi guys. So I read that one can use an AMD card and on a G-Sync monitor (with a module) from a few years ago and get freesync working on it using the CRU tool. Is there any truth to this? If so is there a guide or any documentation? Thank you.

No, that's not true.

I'm trying to follow this guide to fix an issue I'm having with games

https://steamcommunity.com/sharedfiles/f...=806615157

However, after making the changes and running restart.exe, I'm getting no display and have to F8 to reset.

Any idea what the issue could be? I'm only making the changes outlined in that guide.

What GPU? Can you export the changes to a file and attach it here?

I had a problem I haven't found anywhere in the internet:

After using CRU to delete a detailed resolution and restart the graphics device, I can't open Nvidia Control Panel anymore. Nothing happens when I try to open it.

Relevant specs: (please feel free to ask for more info, I've put only what I felt was relevant for this)

CRU version 1.4.1
Windows 10 Pro x64 build 19042.572
RTX 2080ti
NVIDIA Driver 452.06 (DCH)
NVIDIA Control Panel version 8.1.958.0


If I monitor the processes in Windows Task Manager, I can see nvCplUI.exe process actually appears during 5 seconds, and after that, it closes silently with no error messages, no apparent logs saved, and no recorded events in Windows Event Viewer.

The app just closes silently.

Restarting Windows, or reinstalling NVIDIA Drivers and Nvidia Control Panel application doesn't help.

After further investigation, it turns out the problems arise not because a resolution was deleted, but because CRU saved something. I've come to this conclusion because before changing anything using CRU, I'd exported the settings using the "Export" button in CRU.

After deleting the resolution and realizing NVCPL wasn't opening anymore, I've used "reset-all.exe" and restarted the GPU.

NVCPL then opened.

Then, I've imported the configuration backup I'd done using CRU, and after restarting GPU, NVCPL stopped opening again.



The same problem happens if I use "reset-all.exe", restart the GPU, move some resolution up (inside CRU) and save, open CRU again, move that same resolution down (in order to keep everything "unchanged"), save, and restart GPU.

Note I did two changes using CRU, and restarted the GPU only once, but as changes consisted in moving a resolution moved up and then down, at least I expected nothing weird should happen.

As a final note, the resolution I've deleted and moved up and down in the tests weren't the one Windows were set to.

Does anyone know what might be happening here?

A few people have reported this, but I have no idea what could be causing the problem. CRU doesn't touch anything related to the NVIDIA driver, so it has to be a driver bug. Does the problem also happen with non-DCH drivers? What about older drivers? Can you attach the exported settings?

[botounacruzeta]

I haven't tried other drivers, because older drivers gave me small issues in some games, and 452.06 is fine.

I'll test the non-DCH version of 452.06 as soon as I can.

I've attached the default settings I'd exported from CRU right after using "reset-all.exe". (.inf format)

As a side note, I noticed when I import these settings (that should be the default ones) and restart the GPU, CRU shows a "*" to the right of the monitor name, meaning (at least I think so) the current settings are not the default ones.....but they are.

That's not a problem. CRU always sets certain bits a certain way, so that may be different than the default. That shouldn't break the NVIDIA control panel. What happens if you delete the vendor-specific data block from the extension block?

Another thing you can try, install this: https://www.entechtaiwan.com/util/moninfo.shtm

Run reset-all.exe and reboot. Then run MonInfo and create an INF file. Then install the INF file using the instructions here: https://www.monitortests.com/forum/Threa...-inf-files

That will install an EDID override with absolutely no changes. If that breaks the NVIDIA control panel, then that means simply the presense of any EDID override is triggering the problem, not necessarily the content of the EDID override.

Attach the INF file created with MonInfo so I can see what differences there are.
