hiya buttersoft, you don't do any blanking for PVMs? I've found that my Sony PVMs need blanking. They seem happy with just bridging pin 20 (sync) to pin 16 (blanking) with a small wire, but they do need some voltage there. Or do you mean AV switching at pin 8? Yeah, think they won't need that.
gambaman - love your work!

No no, blanking. Most PVM's don't have SCART to begin with, but the 2730's have an option to turn "superimpose" off for the SCART socket - which means they're always in RGB mode. Unless that's superimpose on, but i think it's off.

Ahhhh, I'll have to fire up my PVM2730QM and try that out. At the moment it is gathering dust in my hot shed. I do recall the "superimpose" switch, but it didn't seem to do anything when I tested it - maybe because my VGA-SCART cable already had blanking voltage!

Hi Gambaman,
Alright, I can get into the file and change the parameter, (to 1000) but i'm stuck on how to compile. I've got an AVR toolchain and Git installed, but there's no makefile in your project. And i tried to install MPLAB X but it says there's a missing platform tool called noID which isn't in the downloadable plugins either... ;?
So, if you have any advice i'm all ears. I cannot believe how hard i'm finding it to compile c code, so any pointers would be awesome :)
I'd prefer to compile myself as that way i can test different values, to save asking you to compile a bunch of hexes for me to program.
Cheers!

Hi, buttersoft. I did not create manually the makefile. Instead, I used MPLAB X IDE.

Sorry, I don't remember if I had to install anything else.

Anyway, in case you can not compile it I updated the source and compiled code. You can download it from the project page. I changed the parameter to 740 and works like a charm.
