However, the contrast ratios are fake on a projector more so than on an RPTV.

The light containment, reflective screen, and shorter light path with amplified reflection creates a higher contrast for today's RPTV's. I've seen reviews that state a properly calibrated high-end RPTV can easily maintan average contrast ratios over 5000:1, whereas even the projectors that are stated at 10000:1 have contrast ratios closer to 2000:1 or 3000:1.

According to many things I've read, contrast is the most important feature for picture qualitly, then color realism, then sharpness, and resolution comes in 4th (as long as the resolution is not too far off).

You've stated in the past that you are into a more vivid picture than normal. You should then anticipate that you will be sacrificing the maximum CR from any display if you take that route. What you refer to as color realism, I prefer to call accurate colors. The Z5 will be able to produce a very close 65k color temperature with a professional calibration.

Again, if properly setup, the Z5 will produce an excellent image. Editorial reviews from Projector Central and other highly respected projector sites have already confirmed this. What's subjective is whether you personally agree.

I would take an accurately calibrated 3,000:1 CR projector over an extra vivid 5,000:1 RPTV any day because of the larger, more immersive size to view.

What about the Mitsubishi HD1000U?

I could cancel the Z5 and get that one instead. It would save me around $400.

I wouldn't say a more vivid than normal picture necessarily, but I like a vivid picture to the point of being realistic looking. If you look outside, our eyes view a pretty vivid looking world in real life. I like realism above all else.

The HD1000U is less flexible in lens throw/projector location. It also is less flexible in digital connections...only one.

While it produces a very good image, the $400 savings isn't worth trading the Z5's excellent image. If you had very poor control of ambient light...maybe, but since you can darken your room easily...the Z5 is a better investment, IMO.

That's good to hear. With your room lighting pretty much under your control, I don't think you'll have a problem getting that realism.

econo mode in all.........
the way to go is lcd 1080p.....now getting to 52" in size.......
i have a normal size room (approx. 11' x 12') and don't miss the huge picture.......plus the new lcd flats get 60,000 hrs. do the math bro......thanx

Well there's another Z3 owner in this forum who got over 3,500 hours on his bulb and it still hasn't blown. It's not common that these PJs only get no more than 1k hours.

Do the math bro.

This is why I ordered a bulb replacement warranty for 3 years. I will also buy a spare bulb, and that should hold me over for 3-5 years, at which time I believe some other type of higher bulb-efficiency projector will come out.

My best guess is that you had questionable voltage, dust (did not clean them enough?), or heat issues. Swings in voltage can cause things to run hotter and makes the lamps go out faster. I used to be in the comp. networking business, and let me tell you, offices that had slightly bad voltage (60volt - 140volt pendelum swings for instance), all kinds of things would go wrong (fans will stop turning the right speed, parts will run hotter than normal, etc...). When the problem is not extreme, things just break quicker but do not necessarily show any symptoms right off the bat. Dirty voltage is a huge problem today, especially in certain areas.

LCD 52" isn't bad, but I think it defeats the purpose of watching movies on a huge screen. Going smaller may not bother you, but everyone says the 92"+ screen is very immersive.

Also,

The Sanyo Z5 is the projector I want, but the Mitsubishi HD1000U has less quality control problems. There are quite a few people reporting that the Z5 shipped with an edge coloring issue, where a blue streak appears on the corners and sometimes an orange streak.

The problem is a defect in quality control with the LCD manufacturing process, and when you send the projector to Sanyo for repair, well they won't fix it. They tell you it's within acceptable limits, but I've seen pictures of people's screens with the problem, and the blue was so bad it was unwatchable (take a light blue crayon and color part of the screen). People are having to issue chargebacks on their credit cards, before Sanyo even attempts to do anything, and even then they might not fix it! This is a joke when it comes to warranty service. Sony was hard to deal with for the green blob, but at least they eventually would do something if you keep pushing. With Sanyo, they will do nothing and just stick you with the projector.

Now, not everyone has this, but this definitely scares me enough to keep doing research and see what other projectors can get closest to the Sanyo's image quality.

I will probably order the Sanyo, but god I pray I don't get the blue edge streak or orange discoloration issue.

Sorry for all the posts, but...

I'm now looking at the HC3000U, it beats the Sanyo in contrast pretty badly.

Black levels and contrast are more consistent and generally better on the HC3000U.

I've read all the reviews on the Z5 now, and they aren't much help since they contradict each other. The claim of one review that says the Z5 can beat all the black levels except the Dark Chip 3 DLP is hard to believe, since other reviews contradict this completely. However, if you look in , most people are not that happy with the Z5 as far as a step up from the Z4. They say the differences in PQ are barely noticeable, and the contrast is about the same. Independant expert reviews have confirmed bad contast. It's not bad compared to all other projectors, but it comes nowhere near the HC3000U, which can now be purchased for just $200 more than the Z5.

For the HC3000U
Contrast numbers were impressive at 653:1 ANSI and 1177:1 peak. Thatís largely due to the low black levels of this particular DMD. Note that all measurements were made with the Iris set open Ė closing it reduces brightness about 18 to 20%, but makes those blacks ever richer. The gamma curve I plotted in Video mode, seen in Figure 2, was closer to that of a Film gamma, somewhere around 2.2 to 2.4.

For the Sanyo Z5
Contrast came in at 326:1 ANSI and 438:1 peak, which is certainly an improvement over the PLV-Z4ís readings of 279:1 and 396:1 peak using a single iris system.

As measured above it's an improvement, but only by 10%. The Mitsubishi HC3000U has twice the contrast. Mitsubishi probably has better warranty service, even though the warranty is shorter, and it also does not have the blue-edge blob problem. This is a tough decision, it all goes to the fact of whether or not the place I ordered the projector from allows me to cancel my order.

I bought the PLV-Z2 in July of 05 and I got my parents one a few months later. My parents have already blown 2 bulbs, while I am still on the first bulb at over 1,600 hrs. Mine is ceiling mounted and theirs in sitting on a shelf at the back of the room.

If you mount on a shelf be sure you have plenty of clearance for ventilation. Also if you live in an area that has frequent power outages you may want to purchase a UPS backup power supply so the projector doesn't power down without cooling the bulb down. Also clean the filter often and don't run in a smokey environment. These precautions will help lengthen the life of the bulb.

My parents are waiting till they get it ceiling mounted and a UPS before they buy another bulb. I guess we should have looked into the extended bulb warranty, but like they say hindsight is 20/20.

I love the picture of the Z2 and I hear there have been much improvements in the newer models. I am having a problem with some discoloration and am sending it in tomorrow for warranty repair, but I have not heard of anyone else having this problem.

I don't think you will regret going with front projection, you get a lot more bang for the buck.

Edit: I noticed in your last post that you refered to a blue-edge blob problem with the Sanyo, could you elaborate because this is what I am getting. I hope that the warranty will repair it.

The blue-edge problem is something that a few people had with the Sanyo Z5. The warranty will cover it if it is bad enough, but if it is just showing up on darker scenes, Sanyo will likely deem it within specs. You can probably fight them over it. I wouldn't worry about it too much, it's probably less than 1 in 10 people having the problem, and you can always issue a chargeback to the place you get the projector from if Sanyo refuses.

Just be careful is all.

The bulb warranties aren't full proof though. Their terms are strict and they may refuse to replace the bulb, but we shall see...

Beside the really blue upper left and lower right corner, this projector rock. Anyone can tell me his experience with SANYO warranty service in canada?

I find the blue corners unpleasant, but when I showed the screen to my girlfriend she didn't see it right away, so it's not that apparent. Do you think SANYO will replace my unit? I'm not watching movie anymore because I'm always distracted by the blue black at each dark scene.
