It's weird, I have a couple other resolutions with clocks at 396mHz, like 2880x1800i@105hz, and they show up in display settings. It's also not showing up in QuickRes, which is usually good about showing avaialable resolutions that Windows doesn't (can be found at bottom of this page: https://www.ultimarc.com/download_old.html )

And yeah, this is on a CRT. I'm wondering if AMD drivers have an arbitrary cutoff at 2880 active horizontal pixels for interlaced VGA signals

I don't know. Check if there's a 1000 horizontal blanking limit.
