I don't know why he brought the Sharp projector.
My reason of choosing InFocus is because I have used InFocus’ projectors in several companies, and they worked very well. The other reason is the value it provides - with less than $800, it has 1204X768 resolution, 1700 lumens, and DLP.
I do have a small room for TV. If you like, you can connect the cable to projector to watch TV programs.
