Dual Monitors in DOS? Anyone done this before?

[SuperFreaky]

I need to run 2 cloned monitors each using different refresh rates in DOS 6.22.

I've read that the Matrox G450 can do this...?

If they didn't need different refresh rates I think pretty much any dual-head card would do. In dos aren't they probably going to run at 60hz anyways?

This is for an eye testing program and needs to run at 120Hz on monitor #1. Doesn't really matter what monitor #2 is running at, but its an LCD and maxes out at 75Hz.

Can you run the app in DOSBox? That way you don't have to deal with configuring the video card in DOS at all.

I tried that, it doesn't work in a WinXP DOS box.

I think he's actualy refering to the program named DOS box. It's a program that runs in windows, that fully emulates a DOS machine, not the same thing as the command console in windows xp.

Yep, that's what I was referring to. Here's the link.

It'll do what you want it to if you're doing what I think you're trying to do 😉

i used to run dual monitors in dos back when autocad was still for dos. the monitors will run any refresh rate a program tells them to as long as they support it.

That does look promising, I'll give it a try tomorrow.

I'm really not, but that is awsome. Thanks!
