Let's see if anyone can answer my questions. This week, I bought a DVI>HDMI cable. I use it to go from my new aluminium MacBook to my 40" Samsung full HD (1080p) LCD TV, using an mDP>DVI adapter. The problem is, I can only get up to 1080i on the TV. the MacBook's Display Preferences don't give me the 1080p setting, which I find very weird. Also, I tried watching a film using Front Row, also on my LCD TV. It doesn't play nice with a second screen, though. How do I set up Front Row so that the TV will be recognized as the screen I actually want it to use? I 'fixed' it by mirroring the two displays. Not an optimal solution, though, as 1280x800 pixels is definitely not the TV's native resolution. (That is 1920x1080 pixels.) Then a third and last question. As I have my MacBook placed under my TV when watching a film from it, I'd like to have the display either turned dark, or the lid closed. How do I use my MacBook in clamshell mode when it's attached to a second display? Any help would be greatly appreciated.
