JVC DLA-HD250 Projector – Image Quality
Optical lens shift (or lack thereof)
I can live with the lack of interchangeable lenses, but I do believe a 30K projector should have optical lens shift. My own theater environment is an example. I have a 21 foot ceiling, as a result even with my screen being mounted fairly high, I need the projector to be mounted about 7 feet below the ceiling. Now even with a lot of lens shift I doubt that any projector could be flush with the ceiling (the top of the screen is about 11 feet from the floor). Let me refocus.
Most people won’t have that tall a ceiling, but it would be nice to have the lens shift so that, say with a 110” screen in a room with an 10 foot ceiling, and the top of the screen being 3 feet from the ceiling, that the projector could be flush to the ceiling (reasonable with variable lens shift). With the JVC, the projector would have to come down about two feet. (OK, that’s not so terrible anyway, and is no problem with a motorized ceiling lift that hides the projector when not in use, if you are going that route.)
This JVC projector even lacks keystone correction, which, is just fine. No one has any business using keystone correction to get a rectangular image. Digital keystone correction adds distortion, and the whole idea is to the cleanest possible signal. You’ll just have no choice, and have to mount the projector from the ceiling or on a shelf in the back of the room, at the correct height, to properly fill the screen.
If there was one thing that truly surprising, it is the noise levels of the JVC. Without a meter to do the complicated measurements, let’s just say that the JVC is surprisingly not quiet. The noise level is, however acceptable, but I really was surprised, in that it is about the same, maybe a triffle louder than the BenQ projector, and definitely noiser than some very inexpensive projectors like Panasonic’s AE700u. Once ceiling mounted I seriously doubt that it can be heard even if the room is quiet, but if it were to be shelf mounted right behind seating, it might be detectable during quiet scenes.
