What did you try? You can't just add vertical blanking to one monitor. The monitors have to be synchronized. Changing the memory clock has to be done during the blanking period to avoid corrupting the screen contents, but if the monitors aren't synchronized, the blanking periods won't happen at the same time, so the memory clock can't change without affecting one of the screens.

Issue is that if I edit anything with CRU on that monitor, when I restart the display drivers or restart the PC, my screens (I got 2 screens connected) blink a bit and then windows crashes, mouse cursor frozen and nothing reacts.
Unplugging the TV, rebooting the PC, then deleting the modified driver in CRU solves the issue, but then if I edit again it comes back.

I bet it has something to do with the extension blocks reading/writing?
It's mentioned in the first post that there is an issue with Nvidia and reading the extra extension blocks, but I really don't understand how to fix that issue

After deleting these resolutions, closing CRU, and restarting the computer or running the restart tool I get no signal on all monitors connected. I have to forcibly shut down the computer, disconnect the HDMI, boot back up, and run the reset tool before reconnecting the HDMI to get the TV displaying again. How can I get this to work? My video card is a 3070ti and current drivers are 471.41.

Edit: Looks like I’m having the same exact problem as JayBee, also with an LG set.

Driver crashes are always a driver bug, so it should be reported to NVIDIA. This sounds like a new problem, so try an older driver like 466.77.

I went back to 471.11 and it worked. Thanks for all the work you do and the help you give, you rule.

Hello there,

I just stumbled upon CRU for adjusting my headless ghost's supported resolutions.. well more precisely.. frequencies (for a headless / display-less server with a physical RTX card in it) and I was wondering, given that the headless ghost dongle actually does support writing edid values to it, if that's something that's planned for CRU? I mean.. it's already an awesome tool nevertheless, but if I could just persist the rewrite on the dongle itself, it would be even more awesome.

Thanks!

Hello if anyone is reading this I need help, when I try to use CRU to overclock my monitor from 60hz to anything above, when I restart my computer like the instructions say there are no options to change my refresh rate it is only at 60hz.

My computer is a laptop.(Gigabyte Aero 15, GTX 1060, I7-7700hq, 16GB Ram)
Now the monitor is xrite pantone calibrated, so I don't know if that has something to do with it. Also since there is aa dedicated GPU is it that cru is trying to use the integrated GPU?

If you don't know of a solution I can screenshare add my discord: Kutanna#7611

I wanted to make a separate program for writing the EDID. If you have another way to write the EDID, you can use CRU to export a .bin file to get the raw data.

Hello, 6900 XT with a Dell s3220dgf freesync flickering issue. One of the fixes is to set the freesync range to 80-164 from 48-164. However it does not appear to be working. Range remains 48+, connected via DP port, and set V range via both "detailed resolution" (which weirdly shows the current refresh rate at 59.950, even with the monitor and drivers both telling me its at 164 Hz) and via the Extension Blocks. Any ideas?

I have Lenovo Ideapad 5 14ITL05. And a graphic card is intel iris xe. I tried overclock my monitor but the maximum is 67hz and more is black screen issue. How can I do more?

Thanks for this invaluable utility. I made custom resolution 1368 x 912 for Surface Pro 4 and some games work well, but most just shows black screen with audio. Any idea is appreciated.

I'm using (CAC-1331) Hdmi 2.0 to Displayport 1.2 Active Adapter. I have a displayport 1.4 monitor 1440p 144hz, trying to get 2560 x 1440 resolution 120hz with the adapter (using intel gpu). When I used adapter it would only let me choose 1024 x 768 and 800 x 600 resolutions.
I tried CRU and read the start but still don't really get it, when I added 1080p to standard resolution it worked, but it wouldn't let me type 2560 x 1440 in custom resolution or whatever. I also remember reading the starting post that I don't add it there but in detailed resolution instead? But it was already at 2560 x 1440 by default there but for some reason that resolution doesn't show up on windows options.
Can anyone help me on how I'm supposed to do this exactly?

I don't understand what you're saying. The lower end of the FreeSync range isn't set with a detailed resolution, and CRU doesn't show the current refresh rate. The FreeSync range for DisplayPort is set using the range limits (use the "Edit..." button at the top).
