I've recently gotten a dead Dell Inspiron 1150 to play with. I've ripped out all the valuable parts like the RAM, and am left with a dead mobo, big heavy battery, and the LCD. I'm thinking, as the LCD apparently has nothing wrong with it, I'm wondering if I could wire it to some kind of VGA or DVI connector, and use it as an extra monitor. My current idea is to build it into a photo frame.

Anyway, I've been googling all day, and haven't found much that has helped me. There's reports that people have been able to do this, but there isn't a clear guide as it seems every LCD is different. There's also lots of forum posts around saying it's impossible, and/or expensive, and/or pointless.

But, I'm really hoping there is something somewhere that can make it happen. Any ideas?

From what I've been able to gather about this LCD: it's a 14.1" display made by Quanta Display Inc. with model QD14XL07. Dell part number is DP/N: 0C4011. The cable coming off the LCD is some wide flat connector with about 22 wires going in a ribbon. It appears to connect to the Intel graphics chip RG82852GMV, since that chip is right next to the connector on the mobo, but this might be a bad inference.

Any help would be great :)

In short: It's a great idea but no.

The longer version: Laptops have proprietary controllers to interface these LCDs and unfortunately it's generally very expensive, very difficult, potentially very long winded and may not work even after all that. You have to find a suitable controller which is the hardest part... it's not always impossible but it's likely hard enough to be prohibitive.

To turn the analog VGA or digital DVI in to signals the LCD can display as an image you'll need quite significant electronic trickery and it's not the same over manufacturers or even models from a manufacturer sometimes. This is why it's expensive. The reason it's so hard even if you do have the parts is that you'll likely need to assemble everything yourself, there's no off the shelf conversion kit unfortunately. It would be great if we could use parts salvaged from the crippled laptop guts but they aren't (usually) compatible with a desktop PC with standard components.

Alternative idea: there are readily made LCD (LVDS) controllers, starting from $72 for example from Kontron.

For old notebook LCD-s, this was far more simple. You had to get and old colour DSTN LCD and you could connect it to the video card's Vesa Feautire Connector interface. The backlight could be operated with an inverter taken out from an old flatbed scanner.
