I have a 2011 21.5" thunderbolt equipped iMac. I do work on both PC and Mac platforms. Thunderbolt equipped PCs are starting to hit the market, and I'm considering building a system with a thunderbolt equipped motherboard. I have used the iMac as a Thunderbolt display with my Macbook Air (mainly just to try the feature out) in the past and it does work beautifully. I was wondering if the iMac would also work in target display mode with a thunderbolt equipped PC. This would allow me to get rid of the second monitor and re-claim some much needed space on my desk. If anyone out there has tried this please let me know if it worked. Thank you.
