No that would work.
There will be no res and stretch scaling in BIOS, as Dos always uses the default 640x480 at 60hz anyway, and has nothing to do with the BIOS.
I actually meant stretch settings, as in to stretch the monitor out and up to fill the entire monitor area while in this res.
but your monitor should have some buttons to access menus to change stretch and things manually. Like Horizontal shifts, vertical shifts, and horizontal stretches and vertical stretches...
How old is it?!! It should at least have some dials that turn to change settings, or at best, a built in digital menu.
Its stupid if its only within windows, since if you can only change it in windows, I was going to say to change settings to 640x480 and changing refresh rate to 60hz and then changing the stretch settings, though in DOS, windows wouldn't be loaded to affect these changes!
Are you sure theres no buttons or dials anywhere on the monitor??
Hope this helps
