I want to buy an LED projector.

It must support HDMI input. 1080*1920. I want to play video games at that.

It must support large screen size with 120 inch a minimum.

Sound is optional because I will have my own speaker. 3D is very optional.

I will use it to watch movie, play games, and yes work. I like to work at big TV.

Price range is between 500-2000 USD. I know Acer [H6510BD] is good enough and meet the spec. I want to know if there is anything even better.

One of the thing I consider is

I am willing to pay extra for true 3D (I can play diablo with glasses). I want passive 3D.

3D is unnecessary. I prefer higher res thank 3D. I definitely do not want active 3D glasses. It seems that most 3D glasses for projectors are passive am I right?

I also want very long lamp life. I am going to use this projector for most of my waking hour. I work and play and watch movie at the same screen. Yap the screen will run windows.

I am currently comparing these projectors. None of them I like most because I really don't need that 3D feature. But hei, I might as well enjoy it.
