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.

Ok, but all of the other RGB mods are in HK-47's post, shouldn't the GCN one be there too? Also, where would you put my post?

I was going to put it in the GCN forum, but since HK has RGB mods in this thread(which I just noticed), I will put it in the first post.

EDIT: Added :D

Thanks! What is to become of the S/PDIF mod, though. Should that be moved to the GC forum?

NEW ADDITION:

I have just added a link to Gamelver's thread which shows how to cut the top of the PS1 screen board off.

don't cut off the bottom, though!!!....perhaps I'll do some more testing on how to get the screen even smaller, though......theoretically, the bottom can be chopped off, but there's probably a couple components or traces I hadn't accounted for....

Yay! I finally got my PSOne screen. Haven't ripped it up yet, but I just finished testing it…a little Metroid Prime and some Pirates of the Caribbean through the A/V input jack powered by a 7.4v Canon Li-Ion battery (about 1400mAH). Damn, those speakers are good.

TrueWarlord wrote:You should add that the Psone/Verge/Zenith game screens are all the same:


Samsung LTS500Q1-GF1
Resolution : 320X240 QVGA
Dimensions : 101.76mm x 76.32mm (5")
Contrast : 300:1
response time : 25ms

Differences from the Psone screen:
It should be noted that the Verge and Zenith screens have power directly wired/soldered to the circuit board. The screens do use 7.5v but some have a voltage adapters in thier bases. I have one for a gamecube which accepts and input of 12v DC (console power) and outputs 7.5v to the LCD. I assume that the LCDs for other systems are similar or come with a power adapter. There are 2 decoupling capacitors added. One is a polarized 16v 1000uf, the other polarized unlabeled (and glued to the circuit board) but both are likely added to supress interference.

All mods available to the Psone still apply. This includeds vga in, rgb in, s-video in, brightness, luminosity adjust, saturation adjust, red adjust, led and so on.

Feel free to add/ adjust the info if you see any mistakes.
The resolution is 640x480.

Edit: And how do you make the screen switch to RGB mode?

er, input RGB into it :P? actually, I think it's already set for RGB, since that's what it uses when it plugs into the psone...
