I have a new laptop with Win7 I connect HDMI tv to play a film. When I close a lid, the screen changes its resolution and instead of seeing a film on full screen I see a patch of desktop and half of the movie. Is there a way to set screen size, resolution or whatever is needed, that after closing the lid nothing changes on HDMI?

Which laptop and with lid opened is it working as it should? – Marko Oct 3 '12 at 21:49

After connecting the monitor/TV, press Win+P and select Projector only as shown below. If that doesn't work, try Duplicate:
