Hey, try here:

PowerStrip tray icon > Display Profiles > Configure > Advanced Timing Option > Custom Resolutions

Sometimes you will not see "Advanced Timing Options" button or it will be greyed out or something like that. In such cases you are out of luck. Hopefully you will have it there.

Btw I don't think many W98 games will let you run them in custom resolutions.

That's the procedure I was doing. I'm wondering what to do afterwards, though. I create a custom resolution of 1680x1050 at 60hz, and it asks me to restart, which I do so. But then I don't see anywhere to select the resolution from.

The Powerstrip tray icon should show you your custom resolution to which you can switch to.

Other ideas below are valid for Windows XP but maybe it works the same way in Windows 98 (don't remember now).

Check "List All Modes" button like this one:

and check if you aren't doing "Hide modes that this monitor cannot display" like this:

This is starting to make my head hurt... there's apparently a cloned display on an unknown monitor which shows up in the control panel. Tried disabling from device manager and it's still there. The display disappears when I uninstall the nvidia drivers. And even weirder, the clone display is gobbling up my custom resolutions! I can see the 1280x800 which I created as an option there, but of course setting it does nothing for the real display. Anybody had this bizarre problem before? I'm using the driver version 45.23.

If anyone needs the solution, I modified a setup file (specifically NVAML.inf) to list the resolutions. You can edit the file by unpacking setup.exe with 7zip, changing the needed stuff with notepad, and running setup. Just copy the layout of the existing resolutions in the file but change the res (i.e. 1280x768 to 1280x800)

Great to hear that you got it working now!

For completeness/inspiration, here is similar approach for WINDOWS XP:

You can add custom resolution under the

1[nv_commonDisplayModes_addreg]

section of the driver INF file.

The INF file where you do that probably depends on the sub-brand of the NVIDIA card you use. I edit:

1nv4_dispi.inf

file for my EVGA card, which I think is the most generic file for most/various cards.

I also think the installer then takes that info and puts it into Windows registers where you should also be able to change it, so there might not be a need to edit the drivers for this and reinstall, see:

1HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Videos\xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx\0000

Should be there as:

1NV_Modes

You will need to restart after editing.

Maybe there is a similar setting in the Windows 98 registry as well, might be worth that checking out.
