Custom Resolution Utility (CRU)

[ToastyX]

I struggled with how to implement interlaced support because of the confusion between fields and frames. There's no consistency as to how interlaced resolutions are described. 1080i @ 60 Hz is listed as 30 Hz in Windows and is stored as 1920x540 in the EDID, so it was hard to decide how the dialog should work.

Windows lists the frame rate (30 Hz), but my program uses the field rate (60 Hz), so you'll want to enter 60 Hz. I'm still not sure if I should change that to match. To me, it doesn't make sense to call it 30 Hz. 1080i @ 30 Hz doesn't actually exist as a standard.

"Automatic - Best for LCD" with 1920x1080 @ 60 Hz and interlaced checked will give you the industry standard 1080i @ 60 Hz timing, which will be listed as 30 Hz in Windows. That's probably what you want to use.

If you put in 1920x1080 @ 30 Hz and check the interlaced box, you won't get a standard timing. It will be listed as 15 Hz in Windows if the driver doesn't ignore it. I should probably make it adjust the refresh rate in that case.

If you put in 1920x1080 @ 30 Hz and don't check the interlaced box, you'll get 1080p @ 30 Hz. That may or may not work with your TV.

Make sure you are using version P6 because earlier versions didn't adjust the values.

My program creates EDID overrides, so it's like the monitor supports the resolutions natively. NVIDIA's control panel doesn't do that, so you'd have to create and install a monitor INF file to make custom resolutions work with some games.
