    Laptop screen LVDS mini itx mobo

    Hey guys, I have a laptop with a bad motherboard that has been setting in my closet for a year or 2 and I figured I could make something useful out of it. The LCD is a samsung 15" xga part# LTN150VB-L02. I was looking to get a mini itx motherboard and make a panel pc as a net machine. I don't know anything about the LVDS connection and I couldn't find a spec sheet for the lcd. The connector on the LCD looks like it has 30 contacts but only has 13 wires coming from the LCD, is this LVDS? Also what should I be looking for in a motherboard to use this LCD other than it having a LVDS connection?

    Very likely it is LVDS. The resolution of the new motherboard (I mean the original lcd it used) must match. Be careful, because LVDS is not an entire interface. In normal case, it uses a 20-pin ribbon cable. In that case you hev to re-order those wires.
    In more difficult case it has not 4 (3 data 1 clock) but 5 pairs (4 data 1 clock - quite rare), in this case it is not compatible.

    The resolution is 1024x768. I was planning on using this motherboard http://www.globalamericaninc.com/manuals/2804050.pdf which supports the resolution of the LCD. Where can I find a LVDS cable or have one made?

    It depends. Most devices map the extra 2 least significant bits per color channel (24 bit total) on that 4th diff pair while still keeping the same 18-bit mappings on the first three. Some companies don't follow any standard when it comes to bit mappings for LVDS. So ether way, you may need to do a bit of research on which bits get shifted out on which channel and in what order unless you use a LCD known to be compatible.

    I found a guy on ebay that said he could make a cable for my screen but he said it would cost $68 and $6 shipping. Is it worth it? Seems like high price for just a cable.
