I have just bought one of these boxes - very pleased indeed with everything I have seen. When I first installed it, I used my PC monitor (HDMI) and the picture fitted perfectly. However when I moved to my Panasonic TV it does not quite fit the screen - slightly too large. To get it to fit, I have dropped the resolution one notch, but when I needed to do this with my outgoing W7 home entertainment PC, there was an easy to adjust pair of controls on the AMD control panel for me to make it the right size. Am I doing the right thing?
