Screen FAQ / useful info

If you're making a portable you probably need something to watch it on. (Unless you want to guess what's happening in the game, but I wouldn't advise that) Anyway, this forum is your "Hacking a pocket TV/screen" one-stop solution. Share your experiences and knowledge here.

Screen Hacks
Below is the psone screen's controller card pinout. It's pretty much self explanatory.

To input composite video plus left and rght audio without using the mini av/in jack do this:

Updated list on screens you can use:

-PSone screen
-hipgear screen
-Gamecube screens (low quality)
-Pocket TV screens with an AV input

-Any screen specifically designed to be used for composite, or possibly s-video/RGB can obviously be used. Any kind of screen that hooks up to a console can be used, as well (like the Xbox 360 one, the PS2 7" one, etc.). Basically, if the screen is intended as just that, a screen (an it comes with an LCD board to convert the composite signal and provide power), or if it's part of something else (like the pocket TV) but has an AV input (or possibly output, though if it's just output it's less likely) then it can be used. The first two screens mentioned are definitely the best, though, followed by pocket TV screens.

I looked and this isn't posted in this thread. It's the screen Ben used in the Phoenix. (Thanks for putting it up earlier, HK-47.)

Not quite...

Gamegear, Laptop, Game Boy (and cell phone :P) screens will NOT work by themselves. You would need to buy/build an adaptor board. I know this is on PoD, but it needs to be said here for simplicity's sake.

Hmmm. Fenway Park... Times Square... the Fuji blimp... Lots of nice screens to use! :twisted:

Ever wonder what it would be like to play NES on a times square screen?

Hahah, that'd be great, if somebody broke in or something, and hooked up a NES.
