Greetings, A few weeks ago, Ron one of my reviewers mentioned to me that in this thread just about everyone is measuring lower lumens than Mike, our calibrator came up with. It sure does seem like measurements are all over the place. I've been scanning the thread and encountering calibrated measurements from the 700s up to Mike's 1235 lumens. Someone apparently asked about Mike's calibration. I spoke with Mike the other day.
He stands by his calibration numbers, rechecked his work. Mike did, however, change both his calibration software and his meter this year. Mike's old meter was typically reporting about the lowest measurements of any of the reviewers. JVC in fact once gave us a very hard time about that (RS60) a few years ago. However, he's now using one of two identical meters I've been using. His new meter is recording about 10% brighter than his old one, and about 2% brighter than the other "identical" one that I'm still using. (Mike does all of our measurements for home theater projectors - I use my meter for biz projectors only or maybe or rare occasion a $600 gaming projector).
Still when comparing with some other reviewers, sometimes Mike is a bit higher now, sometimes almost identical. So, he's moved from more conservative to less. I'm always amazed though by the differences from one review to the next especially when you compare both different products and different reviewers. This is the only review I can think of though, where he's well above most others. Perhaps a magic lamp inside?
Regarding the calibration software, since someone asked, Mike did move away from Calman, in favor of ChromaPure software. I'm not familiar with it, but Mike really likes it.
The bottom line is I have no idea why our JVC measured 1235 lumens calibrated. I do know that to calibrate it the changes in settings were pretty minor, it was one of the best "out of the box" projectors we've seen, in terms of accurate color, which I should mention was a huge surprise to me. I'd say it was easily more accurate out of the box, than the THX modes of last year's higher end JVCs.
Based on Mike's work, and my viewing, the RS4910/RS49/X500 has to be considered a superb projector for the bucks. I didn't get either of the higher end models in this year, but with the really impressive black level improvement over last year, I'm really wondering whether JVC's higher end models are really worth the price difference. I assume they are better, in the ways expected, but what I saw here, was a projector dramatically improved from last year, and I've seen little to suspect that the higher end models improved as much. Perhaps it's time for JVC to make this their flagship 1080p projector and going forward this fall, make their higher end projectors true 4K. Hey e-shift is nice, but it sure isn't true 4K. My take - the RS4910 and it's "twins" are the best value in terms of cost vs performance JVC has yet to produce. Stunning picture, great price. -art
