A question is will this circuit simple as it is work its pretty much what i can using now apart from the 2 pins connected to ground ...
Or should i go with the on in the first posting in this thread ?i know there's are that adjusts the sync pulses.
My interest in doing all this is to be able to out put different tv standards from my laptop's video card..
This fellow sort of inspired me viewing he's youtube video.

I should also point out i am making a multi system tv non standard above 64 line so 128 256 so on 6hz 12.5hz 25hz 50hz 100hz frame rates a work in progress !
So this graphics card tv system converter would come in handy ,before i knew of this and i am still doing it as its finished i had a PMT multi system camera for the video testing for this monitor ..i have just tested in 32 and 64 line so far as i had no monitor to view say 128 line ! this will i hope change all that .
