I currently own a Sony KP44PX2U RP TV and want to swap it for a projector, probably the Sony VPL-HS10. A few questions: Can you buy a white screen ready made, in various sizes? Does it come on a stand like ones you get in conference rooms etc.? Does the projector itself suffer from either of the common problems with Sony (and other) RP sets, namely: (1) Yellow/nicotine colour staining on right hand side of screen, most noticeable when screen is bright white? (2) Iffy convergence at bottom of screen? i.e. green or pink glow along black border sometimes? Also, is the black level about as good/bad as a RP set? Thanks guys!! I am really curious as to whether a projector would compare well against my PX2U, image size aside.
