Hi Can anyone tell me firstly why if I am on youtube veiwing a video, in normal 'youtube' mode everything works fine, then, when i want to view a full screen of the video; and click on the full screen icon on the youtube screen my laptop goes to full screen mode but shows no picture on the sound, the screen is divided diagonally by a line one half of the line is black the other white, to get back to the previous screen I have to use ctrl+alt+del. Can anyone help me with this? Many Thanks JP
