Is it possible to use the new apple displays with PCs? I've got a G5 at home, but have to use a PC at work, and I'd like to use my apple display there.

Cheers.

as long as your PC has got DVI on it's graphics card, then it shouldn't be a problem.

Yes, the exception being the 30" cinema display which can be a challenge. Dual-link DVI cards in the Windows world are rare and not consumer friendly. This is likely to change over time, but for now the options are slim and almost completely undesireable unless you have specific, niche needs.

For the other displays which do not require dual-link DVI, they should work just fine.

It requires two things: a video card with the appropriate output (many PC cards are available with DVI), and a compatible driver. In most cases the driver is a non-issue, but it may be a problem with certain displays and certain cards. When in doubt, contact the card's manufacturer.
