Now we get to the experimental stage ,my thinking was i don't have a a 405 line monitor yet but plan to either make one or modify a 625 line monitor shown if i get that far ! depends on mode line and my graphics card cooperating !
But i do have a 625 line monitor to test with if both mode line and graphics card can out put this its a start !
Well this sort of worked i also tried 525 line 60hz this worked also but from the advanced modeline menu as both those are there already i didn't need to paste a mode line for it .
So its a start and a start where the problems start for testing any thing else .
Since i do have mode lines for various tv systems people have posted and can use them to test i gave them a go so far no luck .
i should also mention i have hooked up my scope to view the sync pulses to see if they match mode line results and apart from 625 and 525 no luck .
