PLV-Z4 Viewing Evaluation & Conclusion
I liked this projector - a lot. It had very respectable black levels for LCD. The D5 panel used in the Sanyo has a high fill factor, rendering screen door effect at normal viewing distances almost nonexistent unless you sit on top of the screen. With bright background elements I found 1.75x-2x the screen width was the target seated position to avoid any screen door effect. The real champion, however, was the sharpness and detail of the picture. The optics on the PLV-Z4 are very impressive. You can also defocus the image slightly to achieve a better overall viewing experience should you require a closer seating arrangement, at the expense of some detail. Below is a comparison of the Sanyo PLV-Z4 pixel output and a competing LCD projector product which uses a D4 panel. With the Sanyo providing an extremely sharp picture, and having a decent fill factor (as you can see it is much improved over most D4 panels) the results are predictable.
Here is a side-by-side comparison of the Sanyo PLV-Z4 (left) and a D4 panel projector of the same resolution (right)
DVD: Elizabethtown
Being a member of a DVD rental-by-mail
program helps me to include some of the more recent films on my reviews. Elizabethtown was not the best
quality transfer I've seen in a while. While it didn't have excessive edge enhancement, it
seemed as if the DVD transfer from film was somewhat lackluster (perhaps the guy had something better to
do that night). It did have some good color, however, and I was able to use it to see how well the Sanyo
handled black levels and lots of real world film detail. This is a good example of how HQV scores
don't have much effect on picture quality. Since I was feeding the Sanyo digitally upconverted 720p
video from my Denon DVD-3910 source player, there was no deinterlacing being performed by the projector.
What I was focusing on was color and its ability to render intricate objects in motion and relatively
deep blacks. While I have seen deeper blacks from an LCD projector, the overall picture quality was more
than satisfactory and I was looking forward to a better DVD to check out sharpness and detail (which
seemed to vary by scene in
Elizabethtown
).

DVD: Flightplan
The
Flightplan
DVD was a
home run. It had a TON of dark scenes and a decent transfer quality that gave me a lot of detail to look
at, especially with facial close-ups and clothing. The first thing I noticed was that the post-calibrated
Sanyo was able to peer into the darker parts of the picture without losing resolution or appearing
blocky. There was also no graininess in the deeper blacks. Dark areas of the picture had depth and
retained detail
舑
a visual characteristic that I have seen other projectors do a lesser job at
reproducing. Sharpness and fine detail, once I got a reliable DVD to base my real-world opinions on, was
phenomenal. This is possibly one of the better projectors I've seen in terms of picture clarity and
optics.

Misc HDTV via Digital Cable
We watched plenty of HDTV programs
including
CSI: Miami,
House, and a recent favorite of ours,
Bones
. I was
unable to watch the Oscars this year (or the
"Hollywood self-love-fest"
as I call it), but
the sampling of shows I did see gave me clear examples of the picture this projector is capable of
producing. Consistently color was impressive, blacks and whites were full of detail and sharpness and
detail were above average. Screen door effect during practical viewing was nonexistent at my seated
position.
Conclusion
I believe I may have already said everything there is to say about the Sanyo PLV-Z4. This projector is practical in price, flexible in its functionality, and robust in its capabilities. It can reproduce blacks well for an LCD projector (though it did not strike me as a "DLP-killer") and it can put out color as well as some LCoS displays I've seen. The real strength is in being able to put forth a great amount of sharp picture without significant screen door effect. I was able to watch and enjoy this projector from a very close proximity and only by truly straining my eyes could I pick out the screen door (and I just had my eyes checked, they're fine). The Sanyo is a tough competitor and I now know what all the fuss has been about - it's warranted.

Thanks for all the great information.
native res: 1280x720 pixels
which is also its advertised res. Duh on me.
Anyway, for those who care, here's another in-depth review of the model
http://www.cine4home.com/reviews/projectors/SanyoZ4/Z4Review.htm [cine4home.com]

absent a response, a tentative guess -- L1 = HDMI connection; the other is component? Am I getting warmer?
no , wait, maybe L1 is moving images and L2 is still photos. But that doesn't explain why there are duplicate sets of L1 headers in the review, with different test values. Different inputs?
I suppose I'll get it eventually. Not getting any answers just makes it more fun.
So why not ask a few more --
I now have the HQV test disc, and want to compare varioous modes of my player and projector. Does turning off 'progressive' (i.e. deinterlacing) in the Sanyo also turn off (up)scaling? Or does it still (up)scale an interlaced DVD input? If you feed it a progressive (420p) DVD input via component, is there a way to turn off upscaling to 720p in the projector (or does upscaling only happen with HDMI input)? And what is the 'native' resolution of the Sanyo anyway?
