Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

The blue text in the image is actually white on the screen. CLS RGB(RED), CLS RGB(BLUE), etc. work as expected. I thought the two little boxes in the upper left corner would be red border around blue fill, and blue border around red fill. Hoping again I've just done something silly.

This is with Peter's Picomite HDMI V1.0 PCB.

Oops, I see that other than with tiles, 1280 is 2-color, default black and white
