Is this do-able ?? I've never tried this before but I wanted to see what Mame looked like on a tube. Right now I have it on a 24" LCD monitor inside the cab by dvi from the PC. Beside the dvi port on the PC is a VGA port (blue). I have a connector that plugs into the VGA (blue) and has a yellow rca video connector on the other end to go to the TV.
Nothing shows up on the TV monitor except blue video screen on video input until I change display settings duplicate display. Then the screen on the TV comes on but it's flickering/jumping heavily so it can barely be read and is black and white from the looks of it.
Should this work or am I doing something that can't be done properly or do I have a bad VGA to rca connector??
Any help would be appreciated :-)
Thanks,
Dash

What video card are you using? Im going to go ahead and assume the panasonic is a tv and not pc vga monitor, the picture is jumping because it is not synching up to the tv.hsync or vsync is missing,your video card cant output composite signal through the vga port, or the tv doesnt recognize the signal coming from your card.for now anyways, you may be able to get it working if you adjust some settings in catslyst,or nvidia control panel.
plug them both back in and duplicate displays,go into the cards control app,go to displays,make sure you click on the panasonic,look for the refresh rate and resolution settings,set it to 640x480 and 85hz.see if that works.doubt it will,worth a shot.
I could be wrong, tvs and input signals and refresh rates get very complicated to explain.
your best bet would be if your video card has an s-video output, most tvs have an s-video input in the rear.see if yours does.the most ideal card for this kind of display is the hd 4000 series ati videocards. I have a hd4850 running a 27 ssmsung via s-video.
you could always buy a video converter that converts the vga signal to composite.but this isnt recommended.

Those blue vga to tv cables only work if they came with the card because those cards are designed to output the correct signal for a TV.
As was said one of those VGA to a video convertors should work.
I have one of these.

Works good and has built in over scan adjustment buttons.
Easiest way to hook a PC to a TV and I cant tell the difference between it and the TV out on the various cards I have.

Yeah thanks, that VGA converter box is what I would have to get I guess. The video card that the person who originally did this cab put in a Ultimarc Vga3000. It doesn't give me much of a choice where the second monitor (actual TV) is concerned. I've tried everything and yes I was originally hoping to do Svideo but the TV doesn't even have that)! Lol
So a shopping we shall go.....
Thanks again to the two of you :-)
