Hi guys,

Is there a program available that can display all possible 80 column screen modes (resolutions, interlaced etc).

I need to be able to select a screen mode and then test it with a VGA converter.

There's probably a demo that would be better suited to your purpose, but off the top of my head, Craig Bruce's ZED text editor has four or five display modes (including a couple interlaced ones) which change the number of text lines displayed.  It can actually jam 50 lines of text on the screen, although the flicker is atrocious.  I believe the commands to change the display mode are CTRL + 1, CTRL + 2, etc.

I think Nick Rossi's Novaterm 9.6 also had various 80-column modes for the VDC, and that program is now freely available.

Not especially dazzling, but if you're just looking for functionality, they'll do.

Thanks! I'll try them out now.

VDCDEMO offers up a number of screen modes:

Interlaced:
640x720
720x700
750x600
720x400
750x400

Non-interlaced:
640x360
720x350
750x300
640x200

Fantastic. Thanks
