Sounds good RG! You should get the box! I also use a PS1 LCD screen for testing my RGB mods. For that one I use sync (for the Scart RGB to Component it uses composite video for sync).
PS1 LCD screens can be found cheap, have you seen my posting where I hooked up to a TurboDuo via RGB? Screen looked incredible!
You know I actually got to thinking about the PS1 screens earlier today so it's funny you mention that
I think I remember seeing you had a couple pics posted somewhere...
So the PS1 screen has RGB that can be tapped right? (it's not already outputting it right out of the box)
Do all the PS1 screen have RGB taps, or was it just certain models?
This seems like a good idea as, just like you mentioned, they can be found here in the US and are pretty cheap. And they're light and pretty small so they work great for testing purposes!
