I keep moving to several places and I always want a second display for my laptop, so I am thinking of buying a pico projector.

What should I look for in a pico projector?

p.s.: I use my second screen for playing movies and TV-series while I work on the main screen.

Pico projectors make great toys, but not all of them produce enough lumen to use in anything but a darkened room. So test it in a room without closed curtains. –  Hennes Nov 24 '12 at 3:16
    
Do you have any recommendations ? –  rajat Nov 26 '12 at 9:44
    
No. I went with a regular projector after all pico projectors failed to live up to my expectations. But that was 5 years ago and I assume that there has been some progress since. –  Hennes Nov 26 '12 at 14:59
