That sounds weird and fun, although I can't seem to find the pattern that would have resulted in those numbers. 1024×768@144 (8bpc) works out to 340 MB/s, while 800×600@160 (8bpc) works out to just 230 MB/s, should have been able to refresh even faster. Or is that some other limitation that's not bandwidth? [0]

Was a bit surprised by that double A4 thing btw, but I did the math and it checks out - paper is just surprisingly small compared to desktop displays. Both size and resolution wise (1612×1209 would have put you right up to 96 ppi, with regular 1600×1200 being pretty close too). It's kind of ironic even, the typical 1080p 24" 60 Hz LCD spec that's been with us for decades since just barely fits an A4 height wise, and has a slightly lower ppi. Does have some extra space for sidebars at least, I guess.

[0] Update: ah right, it wasn't a pixel clock limit being ran to the limit there, but the horizontal frequency.

That are the resolutions and frequencies I do remember having tested without trouble. Indeed I could go even faster on the lower ones, but didn't dare to for long, because they sometimes produced very weird high-frequent noises, sometimes unsharpness, and I didn't want to break that wonderful piece of kit.

Did care about 1600x1200 at then 75Hz mostly. All that other stuff was just for demonstration purposes for other people coming by, or watching videos fullscreen in PAL.

It seemed to be really made for that resolution at a reasonable frequency, with the BIOS & VGA thing just implemented to be able to see start up, changing settings, and all the rest just a 'side-effect'.
