More standard VGA modes

Open thedrip opened this issue 4 years ago • 2 comments

Is it possible to implement a more standard VGA mode like 640x480@60.

For testing purposes really, I have two monitors that aren't supporting either mode. Oscilloscope readings of the vertical and horizontal sync look correct for both resolutions, as does the dot clock on the color lines.

I'm out of Monitors to try!

Thanks

It worked great. My issue was that I re-spun the board from schematics and got Hsync and vsync backwards.

Works great, including in the 640x480 and 720x480 modes!
