Dual mode video output? GPS on one screen, DVD on other?

**MikeDeuce** · 02-01-2005, 08:32 PM

Yargh, please help an uninformed newbie here. I can't seem to find any info on this type of setup.

I want to have a touchscreen lcd in front, and a normal lcd in the rear and have it so that both screens can show the same video, like a DVD, or have it so that I can switch the front screen to navigation, or some other type of source, in a single carputer (sorry about the run-on).

Has something like this been done? I know I've seen one of those dvd/lcd/mp3 headunits with the flip out screen that said it could do it, but can't remember the model.

Thanks!

Fist thing you need is a Dual video out video card.
I use Nvidia. In control panel go to Display>settings> advanced.
In my case, I go to Gforce and enable both vga outputs.
then, it gives me the choice on either clone the image on both monitors, or do a horizontal view accross both screens...

Hope this helps,
Danny

well.. actually, i'm hoping to run a 3rd HUD display for the NAV stuff

I was wondering that as well. i was thinking about using a car audio a/v selector. they are made by clarion, farenheit, and some others.

like this the avir-4 or avir-6
souce selector

Ahhh! That's a great idea... I could even see the most simple set up to be like this:

dual head card (set up to be like dual monitor): have one always be for the nav, and one always be for dvd video. SPLIT the dvd video output to a video selector ("a" switch), and run the nav into the selector ("b" switch). Have the selector output to the front display, and run the other end of the split from earlier into the rear screen.

That way you would never have to go into the control panels, or design some other software-based solution and instead have a simple switch box to control everything.

Perfect, thanks everyone!

Well in my Setup (Might not bother with dual display anymore)
I am having a 7" Composite LCD in the back and 2 Snes controllers connected to the PC

I've found a program that was made for dual screen displays

What it does is it pins the program onto either screen 1 or 2 and and keeps it there so each time a program starts up it will be at the exact spot

So i've got frodoplayer or NMC etc as fullscreen on screen 1 which is the 7" Xenarc touchscreen

In the back I have my own special frontend which uses the button presses from the snes Pad to play music watch movies and also play emulators (snes nes mame etc)

and the controllers are setup to only work with the special frontend and with emulators it runs full screen and a small button is used to escape the games to go back to the list.

The audio is used through headphones (i have the main audio turned off on the car speakers and used through there headphones and i have a second soundcard which just outputs D3 navigational commands while i listen to the radio if the back LCD is in use)

The big problem is audio as down here in australia it's illegal to listen to a movie or see the movie in the drivers view thats why i have a soundcard dedicated to GPS

But yeah i reccomend you have 2 frontends running one for you then one for the other screen.

But thats only cause i think it's stupid having a movie playing infront of u while driving

NIN do you think you could hook up a link to the program that lets you open apps in seperate screens every time..I was thinkin sumin along the same lines.

Another question, have you set up two sounds cards?
I wanted dvd to come threw the headphones as well while still being able to hear gps and mp3 and such

had to use it, just to damn funny

If you have an ATI card thier Hydravision program will do it. At least I assume it will only work with ATI cards.
