Correct me if I'm wrong, but it sounds like you set up the UI to function for your slaves for the aspect ratio when they are shown on the left, then when you PiP, it changes the frames a bit. Try setting up the UI and locking it when you have them on the right. That way it will look correct when you PiP over. It will look a little off when its on the left now, but easier to deal with. Thats the way I set mine up and and i have no problems. Also make sure that the aspect ratios match between the left and right screens, ie (mine) 1440x900 main, 3x 240x150 (same screen). 1440/6 = 240, 900/6 =150 This allows the ratios to be the same and have minimal distortion between PiP
