Making the RGB signal stronger?

That is an excellent build I love it. Well done Fusion-One

Fusion-one. Your build looks great!! After seeing that, I might just have to make myself get 4 or 5 screens. So much stuff to do... so little money

Well, I think I kinda understand what you mean by the NTSC signal, and I made a little diagram (I hope MPro doesn't mind as I kinda borrowed his). I would appreciate it if you could tell me whether or not I am understanding this. Also, how is the quality of your video? Is it comparable to a VGA signal? Here is my rendition of your design... and I can almost guarantee that I have it all wrong

Thanks again!!

That diagram is exactly how I connected mine, and it works great.. I just lopped the end off of my rca cable, and soldered the wires directly.. insted of leaving the fat connector on.

When I was running VGA (in black and white) on the screen, I found it to be slightly clearer.. fonts seemed a little crisper.. but were still too difficult to read. For everything else, though. I noticed no difference between the vga and ntsc.. I dunno how anyone could on such a small screen.. :P

M-Pro-
So do you output a sompletely different signal to your 5" lcd? if so, how?

Fusion:
How do you invert the picture?? Did you somehow turn the whole lcd upside-down inside the case?

Bingo, it was very easy to do. took me less than 5 minutes. no modding at all.. just undo screws, flip screen 180 degrees, screw back in place.

Hi Fusion. I'm using a 5.6" Interact screen, exactly the same as yours. Trying to get it to work using a Ati Rage Fury pro video card, which seems to support that 480i arcade mode. I've used exactly the same wiring as in M Pro's tutorial, and i can't get it to work. Can u explain exactly what u mean by using the ntsc signals on the composite cable ? I'm confused.

U keep that original wiring from the VGA to the LCD, and u connect the Composite on your video card's TV-Out, and on the Sync and Ground on the board ? I'm lost, please help

Thanks in advance.

Cheebster, Fusion is not using the VGA mod. He originally did it so that he could use the AV switch in the back, but found out that he could just use the composite signal and ground from a normal AV cable. There is a picture that I posted 2 or 3 posts above that shows what he did. I also was confused and made the pic so that it could be clarified. Hope it helps.

Alright, thanks for the quick reply. But i'm still hoping to be able to make that interact screen to work with vga input... If anyone managed to get it work, please let me know, thanks !

Tom, I'm pretty sure that with A Matrox card, and some of the TNT ones, plus Powerstrip, or some other detailed display settings prog (like the ones that actually allow you to change chip registers), you can change the synch frequency etc as well.

Has anyone gotten Powerstrip (or something similar) to work on a VIA ITX w/ CLE266 graphics chip?
