Is that happening even if you're just using the NVIDIA control panel to add custom resolutions? The NVIDIA control panel doesn't use EDID overrides, so it shouldn't trigger that problem. I haven't heard of that happening with just the NVIDIA control panel.

When you stopped using CRU, did you make sure to delete the override first? Make sure there isn't a * next to the monitor name.

The qnix.inf file has no effect on the problem. It's not needed with CRU, but having it installed won't hurt.

NVIDIA's driver has a bug where EDID overrides don't work properly if something does a hardware scan. GeForce Experience does a hardware scan when it starts, which triggers the bug in the driver. Samsung Magician is also known to trigger this problem.

The problem only seems to happen if the monitor has the extension block enabled while the override doesn't, but NVIDIA's driver has another problem where EDID overrides are ignored if the extension block is enabled without an extension block override, so the blank-extension.dat is just a dummy extension block with nothing in it.

If the problem still happens after enabling the extension block and importing the blank-extension.dat file, then there must be some other way to trigger the bug that I don't know about. I don't know any other way around the problem other than to uninstall GeForce Experience and Samsung Magician.

That will stop the bug from triggering on startup, but the bug might still trigger when you load GeForce Experience manually. I think disabling the NVIDIA tray icon will stop GeForce Experience from loading on startup.

Hi ToastyX i have 2 stars ** by the monitors name in CRU which ever resolution i click on...how to help with this please...also you have given me some great information by telling me that Samsung Magician which i have installed along with the 2 stars ** could be coursing me this problems...however i am totally unsure of how to get rid of the 2 stars ** next to the monitors name in CRU and what ever resolution i click on in CRU be it the top middle of bottom custom resolution including the 60hz resolution which i am scared of deleting or doing something wrong and deleting that i dont know what to to sort out the star by the monitors name....could you please help me with that as in tell me what to do and then i can uninstall Samsung Magician and just try using the NVCP again....many thanks for your help Lawson
