Well, it's probably a little cheeky of me to start the Owner's Thread, given as how I came by the projector (winning the AVS Cedia Contest), but UPS dropped it off an hour ago, and it's already throwing a fine image, even though the room it's in doesn't have any more light control than closing the curtains and waiting til later.
That's a wall mounted JVC 65S998 behind the boxes in the second of the attached pictures; it's a great three chip LCoS RP set, and very thin due to a folded optical path, but was only on the market for a few months before JVC exited the RP space. We use it for daytime and casual TV use, reserving the front projector for films and other content worth seeing on the big screen (although 100" is at the low end of screen sizes on this forum). The motorized screen drops just in front of the RP set.
It was a little sad to unplug the RS1 after two and a half years of excellent service. The RS15 is narrower, and fit handily on top of the Oppo BDP-83 that I picked up during their Early Adopters program. I found a $3.50 right-angle HDMI adapter at Monoprice (third image) that prevented the HDMI cable from sticking out towards the couch.
The power lens cover is very cool. I had just finished carefully cleaning the RS1's dusty lens a few days ago, using a Zeiss pre-moistened lens cloth.
As soon as the RS15 turned on, I noticed was that the initial image was thrown way high and to the right; I had assumed that the default position would be much closer to the axis. I was quickly able to zoom out a bunch and center the image (I project from near the far end of the range for my 100" screen, which drops lumens, but increases contrast). The power lens shift, zoom, and focus are really nice; I no longer need binoculars to focus! The resolution is fine enough for centering, and the backlash is noticeable but modest.
One thing that I don't understand is that when I center the green grid of squares on the screen, and drop in a Blu-Ray Disc, the movie's image is offset about two inches to the right. Weird.
On reading the manual, I noticed that even though the bulb is the same as that used in the RS10 and RS20 (BHL5010-S), the quoted lifetime has increased 50% from 2000 to 3000 hours! That's good news, but I wonder if the RS15 operates the lamp at slightly lower current, or if JVC has simply amassed enough life test data to raise the number, and RS10/20 users will also experience 3000 hour bulb life.
The image is definitely brighter, although this is probably partly the new bulb and the increase in lumens from the RS1 to the RS15. I can still see hand puppets, but that was expected - even with the gains in contrast ratio, we still have a ways to go until the black bars are truly black, especially given my high Power screen fabric.
I did spot one central and two fainter slightly brighter than background vertical bands in a dark scene in Changling. I had that once before on the RS1, and forget what led to it and how I made it go away. A quick switch to The Fifth Element showed that it was not the projector. Some HDMI quirk?
I have a Lumagen HDP to address the oversaturated primaries. It's not a RadienceXD, and the secondaries are not quite where they belong, but it does the job.
I'll need a few hours before I could make any critical observations, let alone run HCFR, and with a wedding in my wife's family this weekend, time will be hard to come by.
