Title: Useful but be careful
Review: This is a savior if you have Plasma/LCD and a projector at the same place and you want one source to get displayed on to two places, but be careful if you have two displays that are not of the same quality i.e. high standard projector that can display 1080/24P and TV that can handle 1080i only, the display get forced to the lower resolution. You can get higher resolution but it is not easy and it is annoying process.
