Like many places, we have a rack with a space for a KVM. Also like many places, the monitor that sits there is a small ancient CRT. I'd like to replace it with an lcd, but I don't have much chance of getting that approved in the budget, and even if I could there's other things more pressing that could use the money. But we do end up with a dead laptop from time to time, and when that happens there's generally nothing wrong with the display. So as something to do in my spare time, I was wondering what it would take to attach a standard vga or even dvi connector to one of these. I'm not talking about using the whole laptop, just the display.

Uhm... There was a similar question in Unfortunately, not a good answer. Googling (when I was curious about it) I recall just finding people who had spent an awful amount of time on it, plus having to purchase other equipment to get get it to work (costing more than $50, not including time/labor). It's a good project, though IMHO I think there are better projects to do own your own time. Really buying a new LCD (from craigslist/ebay or at your local tech store might be cheaper at the end, plus freeing some space on your Rack is also worth something).

Laptop displays use not very standard variants of LVDS signaling. It is not compatible with DVI or VGA.

There is thread about same problem Some LCD controllers (digital signal converters) exist, but are very expensive (200-300$) – osgx Jan 11 '10 at 22:46
Also, there is a success story – osgx Jan 11 '10 at 22:50
That success story is cheating. He uses a vnc-like application to extend the monitor over the LAN. – Mark Henderson Jan 12 '10 at 3:03
