BenQ PE5120 - Performance: Other
Excellent. This is an "entry level" projector, and it is amazing how far "entry level" has come in the last two years. The overall picture is crisp, very dynamic, and colors upon first viewing, were near dead on. I found flesh tones while watching HDTV to be particularly good. This included viewing Jay Leno, college football, and several shows on the INHD (hi-def) network and Discovery HD.
I probably should mention that I was able to place the BenQ projector where I could fill the entire area of my 140" diagonal 16:9 screen. The BenQ 5120's 1100 lumens were easily up to the challenge. For quic
comparison purposes, it had more punch than either the Panasonic AE700u, or even my own BenQ 8700+. That in itself is most impressive, considering it is rated much brighter than the competition from InFocus and others. I have not worked with the InFocus 4805 recently but I am pretty confident that the BenQ has a definite edge in brightness. (The InFocus is rated at 800 lumens vs 1100.)
Overall that will make the BenQ particularly good for Sports/TV fans, as mentioned earlier.
Over two evenings I spent several hours viewing various favorite DVD's including Lord of the Rings, Bulletproof Monk, Amazing Caves (an IMAX production), Men in Black, etc. Consistantly the BenQ provided a very clean virtually artifact free image, regardless of the source. I did not detect any banding, which seems to (although minor) plague many of those $2000 selling price LCD projectors. Since the BenQ is the same resolution as your recorded DVD's there are no scaling issues which can create some artifacts.
Below are images captured from Lord of the Rings and Bulletproof Monk. As you can see from the images there is plenty shadow detail, thanks to the 2000:1 contrast ratio (that is so typical of DLP projectors). If you are not a perfectionist, the contrast, associated black levels and shadow detail are far more than just acceptable. If you are a perfectionist, you really can't expect real perfection in what is one of the two or three least expensive home theater projectors on the market
As you can see, colors are rich. in fact the image quality, is very balanced, with no inherent weaknesses. Blue skys are natural, fleshtones well done. (If there is any shift at all it is slightly to yellow, and in watching I did adjust the tint (only slightly), to compensate.
Unfortunately BenQ only allowed me the projector for a short time, and I did not get to spend the time I would otherwise spend on calibrating and tinkering with the projector.
The really great thing is, calibrating it really isn't necessary, although you might be able to make a minor improvement. As I have said, it puts a beautiful picture on the screen without having to adjust anything.
The good news, is that the BenQ PE5120 projector is DLP. As a result the pixels for an 854x480 projector are far less noticeable than say the Epson Home-10 which has the same resolution but uses LCD technology
If you are sitting about two times screen with back from the screen, you really can't see the pixels, and at 1.5 times they are visible but very minor. Overall they are a bit more noticeable than the $2000 class of LCD home theater projectors, which have the advantage of being one notch higher resolution (1280x720).
Overall, this is a great little projector, and is likely to be the runaway best seller for the holidays. People who find one under their tree will truly be impressed.
The rainbow effect affects a small percentage of the population. When viewing a DLP projector with a spinning color filter wheel, this appears as sort of "trails" of red, green and blue. To eliminate this problem, DLP projector manufacturers have increased the speed of the filter wheels and put more segments on them. This BenQ model, uses a 2x speed, 5 segment wheel, which should make the rainbow effect a non-issue for all but a very few, still that is slower than higher end DLP projectors. That combination is better than found on any of the business DLP projectors currently shipping, but not as fast as some of the higher end home theater projectors with DLP. For example, my own BenQ 8700+ projector, has a 6 segment 5x color filter wheel.
Bottom line, don't worry about it. If you can detect the rainbow effect, and it bothers you, you will either have to switch to a more expensive model, or to an LCD projector, such as the Panasonic AE700 or Sanyo Z3. My belief is that once you have seen the BenQ 5120, the lower resolution LCD models that are closer in price, due to much more visible pixels, will not be acceptable to you. Overall, few will see the rainbow effect (even occasionally), and even less will actually be bothered by it!
