I have a screen that is 4:3 that I want to use with the Fullscreen outputs. however we are using the program in widescreen mode. can any one tell me how to change the full screen outputs to 4:3, I actually want to cut off the edges, so a 4:3 source will show like normal and 16:9 source will have the edges cut off. currently the 4:3 screen shows the full with but is compresses to fit

Thank You
