The 5 pin c64 didn't have separate chrominance output, it only had luminance and composite. For those you want a 1701 monitor The 8 pin c64 added chrominance and +5v. For those you want a 1702 monitor https://gona.mactar.hu/Commodore/monitor/Commodore_monitors_by_model_number.html I would expect composite to be delayed compared to luminance, because it's gone through more processing. Putting the delay in the c64 would not be cost effective as commodore sold many times more c64s than monitors. There is a monitor specifically for 5 pin c64's, I would hope it takes it into account. On the 8 pin c64 then I would hope the luminance and chrominance is in sync, however that doesn't stop the user from trying to use a cable from a 5 pin. I vaguely remember trying to use Y/C on a c128 with a philips monitor using a commodore cable and having all sorts of colour bleeding problems. I was probably trying to use the wrong type of cable, I need to dig it out to see whether I figured it out. Message was sent through the cbm-hackers mailing listReceived on 2017-09-04 11:00:03
