Panasonic's new LED/Laser projector reviewed

Panasonic has begun to ship several new models featuring a 20,000 hour life LED/Laser hybrid light source...

Among these is a 3500 lumen, 1280x800 version known as the PT-RW430U. For those who prefer higher resolution there is a 1920x1080 version called the PT-RZ470U. We have just posted Bill's review of the RW430U. Overall, it is quite a unique product with a combination of features unlike any other projector we've seen and it has earned very high marks in the review.

Last month we posted a review of the Optoma HD25. At the time we did not have the Optoma HD25-LV on hand to evaluate or comment on. The HD25-LV is basically the same product with a higher lumen output (3200 vs. 2000 lumens), more robust speakers (dual 8W vs. dual 5W), and a price tag several hundred dollars higher. To no surprise we received quite a few requests for more information on that unit. It is now in house, and the next projector review to be posted will be the HD25-LV. We expect that to be posted later next week.

Good to hear. Thank you. I don't know what I would do without this website.

Okay, so why would anyone want to get a 1280 x 800 pixel resolution panel projector in July 2013, when the same manufacturer is making the same projector with a 1920 x 1080 pixel resolution DLP chip? I had thought we are moving forward to 4K rez, and not backwards in the resolution ladder.

Any update on the release of the Optoma HD25-LV review? I'm dieing to buy one but want your input first. Thanks

Looking forward to the (hopefully very soon!) release of the Optoma HD25-LV review!

I'm particularly interested in the following:

#1 Noise, noise, noise. I think that's something that's still not given enough attention to by most manufacturers. 26 dB is quite a claim by Optoma for the HD25-LV and somehow, I highly doubt that this value is honest and true. It's particularly suspicious if the HD25 sports the same number (26 dB) in the specs. How is it possible to get +1200 Lumen with nearly the same hardware without more noise? I call BS! I'd love to read that the HD25-LV's audible noise level is 26 dB indeed, but I feel like Optoma is really rather trying to fool potential buyers than to be honest. Same for most other manufacturers. Do we really want more fake/bubble specs throughout the whole industry, like with the mileage of cars or the runtime of notebook and mobile phone batteries? I say no as there's no point. In the end, people will find out and return their projector if they're unhappy with it. So, please post honest, measured numbers about the noise level of the HD25-LV in each mode, like 3D, 2D, eco etc.

#2 How noticeable and how useful in reality are those +1200 Lumen compared to the HD25? I've heard rumors that in 3D mode, the HD25-LV isn't actually brighter than the HD25 - which would be quite a joke, actually. As 3D mode is exactly where one could use +1200 Lumen very well as one usually loses about half of the brightness due to the 3D glasses. So, with the HD25-LV, there's the chance of having 1600 Lumen in 3D instead of 1000 Lumen for the HD25. Why would one need 3200 Lumen in 2D except maybe for business presentations in a bright room? Are there any disadvantages due to the +1200 Lumen? E.g. less deep blacks, less contrast, less vivid colors or that it's simply too bright to still use the HD25-LV as a home cinema projector?

#3 What about the speakers' performance compared to those in the HD25? Are the additional 6 W noticeable? How good is the virtual surround sound?

#4 Speaking of whole industries that fake specs: Unfortunately, that also applies to the specified Lumen for projectors! I don't know a single projector that lives up to its promised/specified Lumens! Usually, the measured values in independent tests are about 20-30% lower than those claimed in the specs and ads. Which is a shame! I can't believe engineers are 20-30% wrong. That would be a catastrophe in most cases. So it's likely the marketing department who polishes (read: fakes) the numbers. I really hope the industry will turn towards more honesty now that we enter an age, where those customers who do care about specs at all, usually do some background research themselves on independent reviewers' sites. Lies will be uncovered anyway, so why not be honest from the begin and gain more trust through honesty in dealing with potential buyers?
