On the other hand, the monochrome picture is rock steady. I'm still using my green monochrome Philips monitor of almost 35 years with the BBQL! Only drawback is the screen size which is a bit on the small side at 12 inch
Ok, Thank you Jan! You may have just saved me a lot of debugging. That's exactly the picture I got so maybe it's normal. If so then no need to try and run pin 9 of the MC1733 out to pin 1 of the RGB connector. It doesn't give me much other than maybe being able to connect it to projectors since if I'm connecting it to a TV I use RF (which is just as good as color composite) and if a monitor then I would be using some sort of RBG to VGA/HDMI upscaler.
I will still investigate why my monitor said PAL but Martin might be correct that it just got confused.
This was a big help! Sad to think the QL couldn't perfect a good color composite picture. Still, maybe doing that tweak with the resistor then Adrian Black (YouTube link I posted in an earlier part of this thread) showed on improving the color of composite might be worth a try.
