Extended Disply Problem

[stublack]

Well **** I have a new problem. After updating the k lite codec the karaoke video is playing beautifully on my extended monitors in my office. But last night when I got to the venue on their big screen TV half of the screen is completely blocked out when playing the video. I have the same problem on my living room TV. Man I hope there is an easy fix for this. The 2 monitors in my office are both Vizio. I have a Sony in my living room and I have no idea what brand the TV\'s are at the venue.
