Here’s a comment from down the rabbit hole:

>Back in the day I spent an afternoon configuring my old 19" CRT like that. I ended up with settings like 800x600x167Hz, 1024x768x133Hz, 1600x1200x89Hz and 1920x1440x73Hz. Many refresh rates were much higher than the stated documentation, and I ran it for years like that.

I’m amazed at that those resolutions and refresh rates were achieved so long ago. LCDs were so thin as to ge unstoppable, but definitely came with trade offs.



Had a 21" Hitachi Superscan Supreme and needed to do the same. Got it from a gamer who couldn't use it because most games at the times programmed the hardware directly, und thus anything you've set up with tools like Scitech Display Doctor/UniVBE/UniVesa got overwritten. Whereas i couldn't care less about that, happily enjoying two pages of DIN A4 in original size next to each other, crisp and clear on that highend monster :)


I used to configure my own non VESA resolutions in the X windows config file.

If the monitor had enough bandwidth you could push it past the standard VESA modes.

I used to run bespoke resolutions like 1600x1200 in the mid 90s on a big Trinitron monitor I bought at a surplus store.

IIRC the only limitation was that the resolutions had to be both divisible by eight.


Honestly RAMDAC was more the limiting factor.


Matrox could do it, later all-in-one Voodoos from 3DFX also, and anything with the shiny transparent blue chips where you could see the die from IBM [1], many better cards with chips from S3 had that. No blurryness at all.
