Odd video modes

I seem to have found a graphics mode that's a combo between 1152x864 and 1024x768: 1152x768! I was attempting to use int 10h to write a coloured screen driver for text mode, but when I tested my code in Virtual PC, the emulated screen went blank and changed to 1152x768. I've attached a screenshot of the properties showing the mode as well as a text file containing the code I was working on at the time.
Anyone find any others that they'd like to share?

this may be a waste of space, but therres a windows 96? and maybe its because the vpc detects it in the os? maybe?

Actually it was my attempt to modify Windows 95's resource files to create a "Windows 96". It was just a project on a bored summer day.

I'm used to setting any mode that is a multiple of eight horizontally...
How about the 416x312 resolution as the largest 4:3 VGA compatible resolution that still allows pageflipping

Well that's not a big surprise. It really depends on the video card; VGA for instance is considered to be a graphics standard and that's why everyone made a big fuss when Mode X and other undocumented modes showed up. Video card designers could also supprot 1x1 (that's right, ONE PIXEL) if they wanted

Hehe - you'd be able to run Quake at 1000000 frames per second!

Speaking of odd video modes, who's still using 40x25 in their OSes? AH=0 [video settings], AL=0 [40x25], INT 10h!

Hmm, never thought about that one. Could be funny!
But that's why I use 80x50, maximum space in a 640x400 or 720x400 resolution!

But people like when it's easier on the eyes... so I provided both 80x25 and 80x50.
