Re: Nomad RGB TFT Screen

The issue with LCDDRV is a little complicated.

The LCD panel itself is 320x240, with RGB stripes aligned horizontally.

The LCDDRV's scaling seems to scale things in a 960x240 space, such that data falls into the wrong subpixel! So, unless everything is aligned perfectly to subpixel triad edges, color artifacts appear. This is why I do not like it.

The dot clock is a little higher than that of the Nomad, so you get some borders on the sides, and color artifacts as a result.

I wonder about replacing the crystal with some multiple/division of the Nomad's master clock.
