Playstaion 1 projector image

[jonbest]

Hi, I am trying to play a playstation one game on my projector (Final Fantasy 9). I get an image but there is a lot of line flicker. I was wondering if there is any way to reduce the line flicker or if its a problem specific to psone games.

My setup is as follows:

Playstation 2 rgb scart to jstechnology rgb to component converter box. This then goes into the BenQ PB2250 DLP Projector. The playstation and game are both PAL so it runs at 50hz.

Thanks very much.

Playstation 2 rgb scart to jstechnology rgb to component converter box.

Why not ditch the converter box and see if that helps ? It can't hurt to try, My ps2 works fine playing ps1 games on my projecter.

All I did is open up the scart connecter and connect some shielded 1core cable from pins 15 (red) 11 (green) 7 (blue), all earthed/shielded on pin 17, put some phono sockets on the end of each, plugged my phono component leads from the pj into these sockets and changed my playstation2 to 'component out' from the main menu (if your scart is still plugged in a tv the picture will have a green hue now on the tv but be fine on the pj)

Only trouble is on a 8ft wide screen ps1 games look really blocky but play fine.

I have tried using composite cables and it works fine. I'm not sure why it doesn't work well through the converter as the playstation 2 games look fine. Perhaps the component to vga cable isn't of good enough quality.

I wasn't refering to composite cables but using Component cables plugged into the added sockets on my scart plug and then setting the ps2 to Component Output

Perhaps the component to vga cable isn't of good enough quality.

I'm getting confused here , your projector (BenQ PB2250 DLP) takes component input so why not use the most straight forward connection ? ps2 in component out mode > component cables > pj component input. No messing with the signal means less problems and the best possible picture quality (although with a ps1 game it's a moot point) so as I originally said ditch the converter box, all this converting from rgb-pal to component to vga is likely to upset the timing signals possibly giving the problems your seeing.

I don't actually have a playstation component cable

However since the projector can only accept a vga connection for its component input I don't think I can actually use one. The only component to vga adapters I have seen have been expensive.

neither do I I took a standard RGB/Scart playstation cable and Added three extra connectors (phono sockets), it was actually a ps1 cable since I already had it and they are just the same as the official ps2 cables. (The only real difference between RGB/Scart and component is where the sync signal is! )

You don't need any adapters, all you need is the correct cable ... 15pin d-sub on one end and 3 phono connecters on the other as shown on page 15 of your pj manual. This then plugs into the phono sockets that I've told you to add to your playstation scart cable and bob's your mother's brother.

Heck you could make one, see http://www.interfacebus.com/Design_XGA_PinOut.html for the pinout of a 15pin d-sub, I bet you only need to connect up pins 1,2,3,6,7,8 cos the sync signal is mixed with the green signal with component.

Your making it more complicated than it needs to be, your ps2 can output component signals and your pj can accept component signals it's just a matter of the right cables between the two. Remember KIS (Keep It Simple) less room for problems and/or mistakes.

I'm happy to help, I only know all this because I was too bloody minded/tight to buy converter boxes that I was sure I could do without when I wanted to connect my ps2 to my pj, so I spent an evening reading up on the internet on video standards & connecters etc until I'd worked out how to connect the two together.
