This is not true at all. I do lots of research. It is obvious to me you are more concerned about being a "tech bully" than you are about giving advice to others in a respectable fashion. If I post something incorrect, I don't mind being corrected, but you have not even seen a JVC RS-45 yet, the RS-50 had calibration issues and some stuff that the RS-40 didn't even have, so you're jumping the gun.
The Sony wasn't even as good of an option for either of us at its price, both JoesYah and likely would have bought a DLP if we didn't get the JVC at an absurd price, and the DLP pickings are so slim right now.
I didn't ask for your opinion on my purchase, for all you know I am buying 10 different projectors to compare with, are you going to correct me on every purchase? ....
I go by a few select sources of information that I trust, that I know to have been accurate in the past, not by people that typically already favored the Sony from the start. You have also put words in my mouth several times (like the motion thing, claiming I said the JVC was better). You have a right to post opinions, but you need to tone it down a bit, your posts are too aggressive which doesn't add credibility to them, it detracts credibility.
My "excess sharpness" comment was about him seeing a DEMO to make sure the controls are setup correctly, not about what causes the problem. When you have any noise in the image, artificial sharpness increases it, so if it starts out a little more noisy, there are ways to clean it up sometimes.
First, Mike Huffman, a designer of calibration software who's expertise level on this particular issue is much greater than those people you mentioned, and has never stared me wrong on sharpness comparisons, and has seen hundreds more projectors, has said their is a mild focus uniformity issue with the Sony. He doesn't just see one example unit, he sees many. He calibrated a JVC and a Mits hc9000d not long before he saw this projector. People from AVS that I trust and have seen both projectors said the JVC's are sharper, they said it's really mild, but the JVC is sharper. Another source is there are people in the actual Sony hw30 thread that see the uniformity issue and reported about it that are owners themselves and have no reason for bias.
Sharpness is partly convergence luck, so you have to take multiple sources.
Furthermore, nearly every single JVC vs. Sony review from professional sources (like PR or others, even Cine4 sometimes) I've read when comparing low-end JVC's to low-end Sony's going all the way back to the RS-20, the JVC is almost always reportedly sharper. When did Cine4 say the Sony is sharper, I do not believe he said that, and if he did, well then he probably just got an abnormally sharp unit from a basis of luck, it happens.
I have seen multiple units of any model that was NOT SHARP because it had bad convergence, convergence applies in this situation. That is why it is hard to make the comparison. LCOS and LCD are based partly on convergence luck, the pixel correction abilities are not 100% resolute in solving the issue. That is why you have to really be careful about comparing one unit to another, you need multiple sources.
Low-end Sony's are typically reported to be a little softer. This hasn't changed over the last few years.
Measuring sharpness differences between two projectors is not really a simple thing always, but there is a lot of BIAS in this forum tilted one way or another. Some of it is accidental, when someone favors a projector overall they tend to see things that are not really there.
This is why I'll wait to see the projector for myself and make my own conclusions.
I also completely disagree with your comment about other technologies cannot provide the window effect, I have seen it for myself, DLP certainly seems to be the master at this so far, but I'm reserving judgment until after I see the RS-45, and I definitely wouldn't say other technologies can never provide this effect. I have myself noted that LCD lacks this effect at times, although I did see it on the Sanyo several times, and furthermore the RS-45 is not an LCD.
