Not sure where to post this, but:

I need help finding a projector for my PC. My primary needs are:

- at least 720p, I game ATM at 1680x1060.
- screen size ~ 1.5m
- fast refresh rate for 3D (120Hz)
- budget of £700.

Is this reasonable?

I play Crysis and Oblivion mainly, but quite a few others too, and think it would look brilliant on a big screen (and in 3D, in time). Can anyone recommend any decent projectors for this?

Not at that budget. The size you gain with the screen will be more than offset by the lost resolution. If you insist, get a 768 not a 720 projector. DLP over LCD to eliminate blur.

Speaking from experience, a projector is great for 360/PS3, but with a PC you give away one of it's biggest asset in gaming, graphics.

Oh, OK. Well, that's that scuppered. just wanted to have a big screen really. I'll just wait 20 years though. Thanks for that.

Do you have any suggestions on how to get a big screen without using a projector (lots of LCDs etc.)?

A big LCD monitor and sit really close...lol.
