    Installing a second monitor

    I want to install a second monitor on the back of a headrest so my 4 yo daughter can watch TMNT. I currently have a Lilliput Touchscreen in the dash & I'd just like a plain display LCD for her. How to I hook it up to my Voom PC2? I don't think I'd fit a video card inside the case so does that mean I have to succumb to a new case or can I run multiple feeds off the motherboard output? I'm not concerned about having the same picture on the dash monitor as I can just turn it off so it won't distract me from driving.

    Heres a shot of the back of my case:

    I'd suggest a VGA display splitter. They're about $30 on some sites. Make sure to get the right gender connections for what you need. After that, you'll need to run a slightly long vga cable from the splitter to the second monitor in the backseat and then a short one to the main touchscreen in the dash.

    At least, that's how I'd approach it

I have a friend who uses this exact one at work and swears by it, but I was focusing on the forced mirroring aspect. Some of the more advanced USB's allowed non-mirrored displays which is a good solution for doing it without buying a dedicated graphics card. I haven't really looked into it, but it may have a tiny bit of processor usage for such an application.

    Are you wanting the same picture on both screens?

    I'm quite happy to have the same picture on both screens, doesn't concern me.

    Will look into the other 2 options though. Thanks

    OK. Any recommendations on a screen to use? I'm having trouble locating an appropriate monitor with VGA input to use

    There are very few out there. I had to buy headrest with composite only and get a contact in China to program VGA controllers for them.

    But here is the few I found :

    It might just be easier to use Composite only Headrest screens and then just use a VGA-to-composite splitter to run them. Then you can buy whatever size/style headrest monitors you want to.

    Looks like Lilliput is making the 7" with VGA in a headrest but I'll be darned if I can find anyone selling it yet
