On the front projector forum there's much discussion about de-focusing LCD projectors to reduce screen door and motion (peekaboo) scanlines.


Can one get at the lens in any of the Sony Grand Wega units? I'd like to recommend one to a friend who doesn't like the front projection aesthetic or the price of plasma if I know he can do the de-focus thing.


Thanks

At normal seating distance (2x the screen width for rear projection TVs) you should not be able to see the actual screendoor.


Besides, since the lower fill factor of LCD tends to soften the picture a bit, I wouldn't recommend defocusing further.

Thanks for the reply, but I'm not sure what you mean. Low fill factor in an LCD gives the appearance of greater sharpness because of a highly visible grid. That's why LCD front projector types often de-focus two or three clicks.


Clearly this is a matter of personal preference, so I repeat my question, " Does anyone on this forum know whether it's possible to change the focus setting on a Grand Wega without dismantling the set?"

The Low fill factor of LCD *supposedly* gives the appearance of greater sharpness, but I simply don't see it on Rear Projection Units. DLP is noticeably sharper with HDTV material.


Have you watched the Grand Wega at a normal seating distance? Again, I don't think visible screendoor is an issue.


But if you just want to soften the picture, I'm sure you can turn down the sharpness...
