I've read on a couple websites that they're compatible with analog RGB CGA - SVGA, but I don't see anything in the datasheets about the horizontal sync or any mention of what they're compatible with beyond an 800x600 resolution.

I think they were laptop screens and so they only have the ribbon cable connector. Are there cables available that would connect these to more standard size connections, or would I have to hack up something?
 
I'm not very good at reading datasheets, but I *think* what you're looking at is the LCD equivalent to a bare tube. Just the screen, no driving circuitry. You'd need an LCD "chassis" to actually use it, and with modern laptops it's standard practice to build that circuitry directly into the motherboard, so if these were only used in laptops, fat chance you'll find that. Just like with CRTs, the driver board determines the resolutions and frequencies supported, but keep in mind, that since LCD is a pixel array technology, the driver board must either internally scale the input signal to fit the panel, or only use a portion of the panel. As a result, they usually only support certain fixed resolutions -- it takes a specialized arcade-intended driver board, or an intermediary scaler board, to make an LCD in an arcade cabinet practical.
 
You could be right. Although I did a quick search on Ebay and I see one of the sellers has photo of it actually running.

Suppose it could be a stock photo /shrug

Nah, that's too sloppy to be a stock photo. Worth noting, though, that's the only picture -- he doesn't show the connecting boards. He may be driving it from a laptop offscreen, or there might actually be a regular driver board for those units. Send him a message and ask.

Keep in mind you'll still need a custom driver, or a scaler card in the middle, to interface that panel with most arcade boards. Even made-for-TV drivers will only work with 480i (and maybe 480p) games -- they'll reject a 15khz progressive signal.
