Just a quick (easy) question: Given a straight-forward setup (pj centered, right height, correct angle, right distance, etc)... Should the RED and BLUE lenses/tubes be at the same angle wrt the green lens/tube?* At the moment I've got a "professionally set-up" projector with the BLUE tube/lens at a different angle wrt the RED-GREEN angle.... and the BLUE raster shift (in convergence) pretty much at 100%. Is this a big NO NO? And will it actually do any harm (eg: stressing components)? (The blue raster is visibly not the same offset from the tube edges as the red, as well, btw) Thanks for any suggestions/advice/etc... *IE: If the RED-GREEN angle is, say 20 degrees, should the BLUE-GREEN angle be ~20 degrees as well??? At the moment you can see the difference in angle easily just by looking at the front of the projector.
