Reply To: Commodore 128, RGBI & GGLABS’ CGA2RGBv2


Thanks for that video! I had to write my own program to generate a checkerboard pattern for 80-column mode 640×200 which ended up being fun.

I have an absolutely rock solid, vibrant, jitter free image. The only “weird” part is that its absolutely fitted perfectly to the LCD screen – I’ve attached a photo. The colors in photo look bad, but in person the colors are solid and look excellent.

Is there some way to create margins on the edge of the screen at all? So its not so tightly fit to the bezels on the screen? If I adjust H. synclen or H. backport by a value of one, I cut off either side of the screen. If anyone else has a C128 these are settings I am using:

240p / Line2x

H. samplerate 1016
H. synclen 20
H. backporch 241
H. active 640
V. synclen 3
V. backport 36
V. active 200
Sampling Phase 11 degrees
