Allan Tépper at the Pro Video Coalition has a great solution for monitoring video using thunderbolt and a Sony KDL-40BX420E, which will work with US power and supports, both PAL and NTSC frame rates as well as 23.976 and 24 FPS. Very very cool. The monitor is grey market in the US, so he also recommends a third party warranty. This is a inexpensive and great solution for monitoring.
