Custom Resolution Utility (CRU)

Quote:What happens if you delete the vendor-specific data block from the extension block?

I've tested it now. Just ran "reset-all.exe", and deleted the vendor-specific data block from the extension block. After restarting GPU, the same problem happened: NVCPL doesn't open.

Quote: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.

I'll do that later, and post the results.

Thanks!

Done.

Steps I did:

-Ran reset-all.exe;
-Rebooted PC;
-Disabled driver signature enforcement in Windows before it restarts;
-Opened MonInfo, and created inf file (attached);
-Installed inf file (right click -> Install. Windows asked if I really wanted to install the unsigned driver, I answered "Yes", and then got "Operation Completed Succesfully" after that);
-Restarted GPU;


After doing that, NVCPL actually worked.

If you open CRU, do you see "(active)" and "*" next to the monitor name? What happens now if you import the CRU-exported settings and restart?

Yes, I see "(active)" and "*" next to monitor name.

In this condition, NVCPL works.

If after doing the steps:

-Restarted GPU;

, I import the CRU-exported settings and restart GPU, NVCPL doesn't work anymore.

I did other two experiments:

-Ran reset-all.exe;
-Restarted GPU; (NVCPL worked after doing this)
-updated monitor driver using "CRU exported settings - default.inf" (default settings I'd previously exported using CRU);
-Restarted GPU

NVCPL stopped working after doing this.


After this:

-Ran reset-all.exe;
-Restarted GPU; (NVCPL worked after doing this)
-Opened CRU, and imported "Monitor Asset Manager.inf" (default settings generated by Monitor Asset Manager);
-Restarted GPU

NVCPL stopped working after doing this.

What happens if you click the "Edit..." button at the top and enable "Include if slot available" under "Range limits"?

I have a Samsung c27fg70 which I can´t set at 144 Hz because of a defective firmware https://www.youtube.com/watch?v=Ad4emOwpFEI.

Could this software help me? I'm trying it, no luck so far, can I do something?

-Opened MonInfo, and created inf file;
-Installed inf file (right click -> Install. Windows asked if I really wanted to install the unsigned driver, I answered "Yes", and then got "Operation Completed Succesfully" after that);
-Restarted GPU;
-Imported the CRU-exported settings using CRU;
-In CRU, enabled "Include if slot available" under "Range limits";
-restarted GPU;

NVCPL stopped working after doing this.

I did some other testing (restarted GPU 116 times already), and NVCPL worked after doing above steps, but only after enabling both "Include if slot available" under "Range limits" and under "Serial number";


If only "Serial number" is enabled, NVCPL doesn't work.

I could also open NVCPL after doing these simple steps:

-run reset-all.exe;
-restart GPU;
-In CRU, enable both "Include if slot available" options under "Range limits" and under "Serial number";
-import the CRU-exported settings (default ones) using CRU;
-restart GPU;

However, when trying to do my final goal (delete a detailed resolution from CEA-861 extension block without blocking NVCPL), there's no way NVCPL will open after this.
I tried the steps above that worked with CRU-exported (default) settings, replacing the inf file with the one that I exported after deleting the resolution, but there's no combination I did that enabled NVCPL to actually open.

I also tried that option "Import Complete EDID" (that ALSO worked alone for CRU-Exported default settings), but for the CRU-Exported "Edited" settings, no way. NVCPL doesn't open.

Don't import anything. Just run reset-all.exe and restart. Then enable the range limits and serial number. Does that work? Then try deleting the resolution from the extension block.

Does that still happen with FreeSync disabled?

I've tried this.

If I run:
-reset-all.exe;
-restart GPU;
-only enable the range limits and serial number in CRU;
-restart GPU;

Then NVCPL doesn't work.


I noticed something in CRU I don't understand: it shows the monitor two times. (see attached picture, that corresponds to clean default settings). I don't know if it's due to GSYNC module, or if it's normal for every monitor. (There's only one monitor plugged to my PC).

Anyway, I tried to enable and disable the range limits and serial number also for this "second" monitor, but it doesn't help.
