I was forwarded from Stackoverflow to ask this question here. I am running a psych experiment on an old MS-DOS computer. When I ran the experiment on a different computer that is split via a switch with a computer running Matlab on Windows which uses a different frame rate it seemed to skip some frames. I would like to know the refresh rate from the command line in MS-DOS Version 6.22. Is there a way to do this?

Unlike windows today, there was nothing built in to MS-DOS 6.22 to look-up there refresh rate unless the software/drivers installed with the hardware device added that functionality.

There might be a label on the video card installed stating the spec, or you may need to search (google) for hardware documentation for the video card.

Google for "VBEhz". Works flawlessly with old videocards. GeForce2MX worked, but GeForceFX5700 and Radeon9600XT didn't.
