Thread: The Playstation screen->VGA mod update

OK, Last night, got the latest detonator drivers installed with the GF2MX.

Powerstrip under Win2k now offers 640x480i (arcade).

Tried it through the screen.

Lousy picture. Not stable at all, text unreadable. Brightness and contrast good, but that is about all.

Worst thing was, I still got intermittent rolling, and the top of the display was distorted, about 1/5th at the top, just lurched to the left.

Picture was worse than that I got from the DVD player through the composite.

Will try putting the Matrox back in, and compare TVout with the VGA picture. May end up using TVout after all.

Also will try a lower resolution, and also, for Matrox cards I with given this piece of advice by one of the guys on the uk.comp.homebuilt Newsgroup.

"BTW, and I have only just remembered this :-)
Since your Matrox card is a DH, the easiest way to do it is to connect
pins 12 and 15 together to tell the G450 that it's connected to a TV,
this makes pin 4 output composite sync at the correct frame rate which
you connect to the sync input of the LCD instead of the separate H+V
syncs :-)

Connecting pins 12 and 15 on this card tells the card that it's primary
display is a TV and it thus switches to TV out mode - but in RGB.
Simple :-)

Might give this a try too. See if it works out.

I checked all of my connections, any that looked rough I desoldered and reconnected, made sure that none of the colours or the synch lines were touching, and that ground was good. Didn't make any difference.

I think it may be the cable, and my soldering. I'm going to try the Matrox card again, instead of the GF2MX, or maybe try a lower custom resolution.

The picture was clearer and steadier when it was at the wrong resolution/synch/refresh than when set to Arcade 480i though.

May end up going back to composite though.

You can do it! [/B]

Will give it a shot atleast

That looks fantastic.


I have it hooked up with composite at the moment, have a couple of shots of the card at 640x480, and 800x600, with Fonts pumped up (Matrox composite out is particularly good quality).

I post them, and some of the front end I plan to use (Binary Metal Digital Theatre (the free original development version, not the new commercial one)) once I get home tonight.

Still having a weird problem though.

When the Matrox was installed under 98, it wouldn't show arcade as an option (latest drivers, correct build of Powerstrip).

So I pulled it. put it in my PC, and put my GF2MX in the carpc. The Matrox then showed arcade as available in my pc (as it did for the GF2).

When I installed win2k on the Carpc the GF2 with latest drivers showed Arcade available, but I couldn't get the screen setup right. Figured maybe the GF2 output wasn't as good quality as the matrox.

So having seen that the matrox could do Arcade, I pulled it, and put the GF2 back in my PC, and shoved the Matrox back in the now Win2k Car PC.

Bugger me, latest drivers (same as used on XP), no arcade option available (when either one or two heads attached).

Getting annoying. May need to find a different card afterall, or maybe a different Mobo and processor (Maybe a K6-2 400 is a little slow). Give it a few months then do a rebuild.

Fraid so for the moment

You can do it!

I love the Video. Excellent.

I've decided, for the moment, It will be composite because the mobo I have, with the Matrox can't see interlaced resolutions like the GF2 can.

Will fix that later, want to concentrate on making the screen mount/release system at the moment.

Next will be to grab one of Armins touch screens, then when that is done, I can plan for reworking the connector, and seeing if I can get RGB any better again.

I dont understand what Arcade is
