Have you set up the right frequencies using power strip and selected interlaced?

Yes. I have tried every settings on powerstrip but no help. The image on the screen get´s better but not enough.

Hello all,

I got my Joytech PSX2 LCD to work with powerstrip but I can only get 640*480 and 800*600 res to work. I cant get 720*576 to work at all. I have tried starfox`s settings but cant get a stable picture. What would be the native res for this LCD. Anyone have any ideas.

Btw i`m using a Matrox mystique 220 with Csync.
If you need info on how to mod the Joytech screen post or mail me.

Damn unfortunately i didn't knew this website before otherwise i think i could have been helpfull, i made this working since 2002.
I'm using a PS1 lcd display which expects RGB+Sync. Unfortunately mine was damaged when bought but that's why i get it a low price too but it works fine with X server.
I'm using a graphic card, one old S3 3D/2x.
Everywhere where i've been on the net this card is related as not working for driving rgb+sync.
I'm using a little electronics between the card and the lcd one transistor, few resistors and diodes and a little power supply that i lowered at 1.5V just because 5v is really too much.

You have few snapshots here Porsche Gemballa

Here's one really simple interface http://www.sput.nl/hardware/tv-x.html

For those having problems with the display driving, try to have a look here

After reading page after page after page I just had to register to ask if anyone has any solutions as what might be wrong in here.

The attachment is the result after connecting the Sony PSOne LCD to my Matrox G400. I've tried both CSync and also combination with 7486 and the result is the same.

The image is rapidly wobbling sideways, a lot more when the display has just been turned on and looks like the one in the picture after it has been on for like 10 minutes.

Plain composite video works stable, RGB from VGA does not. Getting the adjustments done with Powerstrip was quite easy after Googling for PAL-video frequency values. The only problem now is the shaking sideways.

I'm drawing the power with 8V regulator from the PC PSU 12V line and as the composite video works OK I'm thinking the power is not the issue. I also have another Sony PSOne LCD (those cost only 50 euros piece) and it has the exact same problem.

Any help would be appreciated.

sorry to resurrect this, but I am attempting to mod my PS1 screen. I have a vga cable but pin#1 does not seem to be connected to any wire. I can narrow them all to wires but they dont correspond to what I would expect. I have the same results with two cables. I did look at the pin numbers next to the wires themselves but they just dont seem to be correct. any ideas what I am doing wrong?

haha im an idiot. i didnt realize the thicker cables are actualy 2 cables! doh! I got it now
