Hi ToastyX,

I just went into my registry, and the NV_Modes key now has just this: {*}SHV 99999x99999=1 in it

There is another key called "NV_Modes.bak" which has a larger list in it with resolutions divided into sections SHV "resolutions"=1, =1F, =1FFF, =3F, =3FF, =7B, =7F, =7FF, =FFF, and S "resolutions"=1, =8032

Wondering if I can just can delete all this stuff and put in the resolutions by hand, and if I need to remove the .bak file, and/or should delete the 99999x99999=1 entry.

For context, I have 3 displays hooked up; 2 of them are fixed resolutions (1920x1200 and 1920x1080) and the other one is a CRT capable of displaying resolutions up to 1600x1200 in 4:3.

It looks like at least 1 resolution that is available in my Nvidia control panel is not present in the NV_Modes.bak file, so I'm thinking maybe the 99999x99999=1 entry doesn't necessarily refer to that key for it's list. Perhaps it tells it to poll Windows Device Manager or something?

Anyone have any recommendations. Thanks

That means you used SRE at some point and deleted all the resolutions: https://www.monitortests.com/forum/Threa...Editor-SRE

NV_Modes.bak is the default defined by the driver. 99999x99999 is a dummy resolution because NVIDIA's driver will ignore NV_Modes without at least one resolution in it, and 99999x99999 won't show up because it's higher than any resolution currently possible.

I don't know what you're trying to do, but you shouldn't need to edit the list by hand if you're using SRE unless you want to set the refresh rate bits, but that only applies to non-PnP displays.
