What should i look for in a projector? I am planning on running my pc and and digital tv through it, and i want it to be able to at least project a high deffinition image

A few things come to mind.
A pj that is HD compatable. At least 1024x768 resolution.
It should have a DVI or HDMI connection, VGA and component.
The more conections the better.
A good video card for your computer that can match the native res of the pj.
I'm not sure about running your tv through it, but a good HD STB should be adequate.
That's for starters.
I'm sure others will chime in.
