The LCD with 15KHz support should serve my C128DCF in 80 column 16 Colour Mode. The C128 puts out an digital RGBI-Signal with is mostly like CGA but needs to be converted in an analog VGA like signal. Therefore I have the GGLabs CGA2RGBv2 PCB which transforms the digital output from the C128 in an analog signal which most displays can handle – if they support 15Khz VGA. The CGA2RGBv2 is no scandoubler and keeps the frequency that comes out of the C128DCF.

If you believe it or not: My configuration is working now. 🙂

After your last mail I updated the firmware of my “retrotink 2x pro” from version 1.3 to 1.5 and now everything is fine. I dont need the passthrough mode any more and the C64VE puts out 240p/288p progressive 60Hz/50Hz (leftmost position of the switch if the C64VE-PCB is build in my breadbin C64 and the switch is at the rear edge of the C64). Now I have a 4:3 picture on my LCD-screen without any timing probs even with heavy load demos like “edge of disgrace”. If i want to have a little softer picture or scanline effect i have to use my retrotink and not the C64VE.

The RF-Replacement (my last order) also works flawlessly because of the precision sockets and the ground pin-headers on my C64 mainboard.

The next step is to update the C64VE firmware to the newest version with the USB-Blaster …

Thanks a lot for your help so far!!!
