Windows 1.01 running in CGA graphic mode (640*200*1).

Windows 95 running in EGA, made possible by a Windows 3.11 EGA video driver. It looks even stranger on a real video screen as it appears stretched vertically. The EGA pallets don't appear to be matching up with Windows quite right so the colors looks kind of weird.

Windows 95 running in 320*200*32. For some reason Quake II doesn't return my desktop to the correct size when exiting. I ran Quake II at 320*200 (just fiddling with the settings) and wound up with this. I reduced the fonts and you could almost use Windows like this.

I found a way to make Windows 95 and 98 display in monochrome (1-bit color).

What I did to get this mode was add a .REG file with the following to the registry, and then the Monochrome option became available.

REGEDIT4

[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Display\0000\MODES\1]

[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Display\0000\MODES\1\640,480]
"drv"="framebuf.drv"
"vdd"="*vdd,*vflatd"

This is actually added by default with a Cirrus Logic driver included with Windows 95 and 98 which is how I discovered how to do this trick. (Warning: trying this is at your own risk).
