I have a 27" Cinema Display that I connect to my Macbook Pro using Mini Display. I'm thinking of building a gaming PC and using the Cinema Display as a monitor. Does anyone have experience doing this? There are video cards with Mini DisplayPorts so that shouldn't be a problem. Mainly I have two concerns: 1. Is there any problem getting audio to play from a PC over the Cinema Display's internal speakers? 2. I've read that there's no way to control a Cinema Display's brightness when you connect it to a PC. Can anyone corroborate this? Are there any ways around this? Thanks for any advice that anyone can offer.
