I have recently connected my tv to my pc via a hdmi cable and use it in extended desktop, however when I use iplayer on full screen (on the 2nd desktop, tv), it will go into full screen but the picture doesnt strech to fill the entire screen, it will fill the screen on my other monitor but not on the tv, the tv is 16:9 and the monitor is 4:3 
16:9 screen
