Looking for DOS based software to calibrate an old CGA CRT monitor

[jesolo]

I have an old CGA monitor that I need to calibrate.
I'm looking for some old DOS based software that could perhaps display a test pattern or something similar on screen so that I can properly align the image.
Must be able to run under DOS on an old XT PC

Trixter's CGA Compatibility Tester has some test patterns that might be useful:

videotst.exe

videotst.exe

I've got a program I wrote years ago. Videotst.exe
It should do the job. Source included, but may be missing some libs.
It's been too many years ago......

I like this! The Bars->"white" is wrong (it should be color #15, you used #7) but otherwise this is a really nice program for convergence and other adjustments.

Glad this thread popped up, I was actually just looking for a CRT calibration tool.
