    Running 3 lcd'S on VIA EPIA m9000

    OK, I want to know if this is possible.

    I want to run 3 LCD screens in my car, one in the front in dash and two in the back of the drivers and drivers passenger seats. Now the question is, is it possible to run one LCD screen thru the VGA (of course this well be the main) but also use the video out also from the VIA M9000 baord and then split that connection to two LCD... Hope this amde since...

    Makes perfect sense, and it's something I plan on doing ... seems though I've been waiting for a shutdown controller for months :-p

    But this is exactly how I would hook mine up, the VGA goes to the front while the RCA gets split to 2 headrest lcds.

    I have a EPIA 800 and can get both outputs working, in windows make sure to set it under the advanced properties in the display tab.

    all 3 monitors will display exactly the same thing, down to the mouse movement.

    Yeah this would work if you video card can drive both outpus simultaneously..

    To save cable you can use the video out ports on the LCDs to "piggyback them" if they have video outs..

    I think my brothers ATI all-in-wonder 64 meg card did video out and vga at the same time.
    Mine needs to be updated.

    The onboard video is only capable of driving one "desktop" so no matter if you use both the vga and the svideo, you'll see the same thing. You'd need a second video card in order to have a display for the front and a seperate display for the rear screens.

    This is interesting as the Eden 800mhz MB I have here in the UK does not support VGA out and TV-Out at the same time. If you have the VGA cable plugged in then you only get a picture on the VGA screen. If you select tv-out in the video card options the VGA screen blanks out until you deselect the TV-Out option again. Easy on a 28inch widescreen, hard on a 5inch display

    Another note, most chipsets with TV-out have a single dac. Which means that you only get one of the two outputs with the full chipsets features. ie. only one output may have video overlay and 3D capabilities. Not a big deal if you aren't playing back videos or using 3D viz plugins for your music. I have tried it with ATI cards and most of theirs have the single dac so the DVD playback window on one of the screens is just black. You could turn of video overlay acceleration, but then you are losing almost halvf of your video decoding speed. Some cards with multiple dac's are GeForce MX2, 4, MX4 and many Matrox cards. Geforce 2 doesn't have it. Just check that the card has dual ramdac's. Another thing to note is that some with dual dac's have different speeds on each making one of your outputs slower to respond. I don't have an ITX board to tell you anything relevent to the onboard video there.
    Another option that might work well is to just get a small cheap scan line converter. That is what I have done on some setups and it works great. Never have to worry if each program will work on all the screens, also you can adjust your converter to fit your two screens perfectly.

    You're righta bout them both displaying the same resolution. It sucks, but it's true, you have to go the multiple vid card route. But if this isn't a problem, and you want a lower end card to display on it's vga and s-vid/rca simultaneously, then your best bet is to download a prog called TVTool @ www.tvtool.de
    It should get you set in the right direction .
