i'm attempting to do the psone lcd mod where you put it on your computer case as a secondary display.

i don't want it as a primary display, so how to i add a pci video card and how do you tell windows that's your secondary display and not your primary?

or can i just buy a vga output splitter? do they make those? and i can solder one to the psone lcd? and still have a vga go to my regular monitor?

here is the link to the mod so you know what i mean.

yeah, i have a high end card in my main computer.

it has a dvi and vga... is there a dvi to vga connector that is cheap?

i don't think there are any cards that have two vga's on the back, since you could probably buy a splitter? i'm not positive though.

but i might just try the S-Video to RCA then i could try the psone lcd without trying to solder the vga cord.

i was thinking about trying to solder the vga cables to the board, but when i spliced an extra VGA cord i have, the little wires are so freaking small, that i think they are made of plastic? is this right? i don't see how you could make it solder right.
 
The cable has to contain more than just plastic to conduct a signal, but any metal core might be so fine that soldering will be very difficult. A higher quality VGA cable (with thicker wires) is your best bet if you decide to take that approach.

And video cards do come with dual VGA output, I have a GeForce 4 TI4600 that has dual VGA out. The purpose of it is to run two desktops, so I can game on one monitor and surf the web on the other 🙂
 
svideo all messed up to my 7" car lcd

I tried running the svideo out from my pc to the rca input on my 7 inch car lcd. Now I hear the this lcd does not accept svideo signal just rca or composite. I was getting all messed up image with the svideo input.

I am not however 100% convinced that if i take a rca video output from a video card that the image will be perfect. Perhaps i need to use powerstrip and set the horizontal, vertical scans etc..?
