Well it's finely here and I only got to spend a small amount of time playing because I had to go to work. I will give my quick down and dirty first impressions and add in-depth later. Open the box and I see a small cheap looking remote. My first thought was that it's a secondary remote. It is very small and cheep looking for a $15,000 (or a $59.95 CD player for that matter) projector. I will say that it works well is back lighted and is very ergonomic. The projector itself is absolutely beautiful with great fit and fantastic finish. It truly looks great and extrudes high end by its appearance alone. The hookups are recessed and might be a little tough for people with big fingers. I fired it up feed 1080p 60Hz (from my HTPC) and the picture synced up but it had tears a was very wobbly. Try as I might adjusting porch, sync, and other settings I could not get it stabilized. Finely gave up and tried 48Hz and perfect (50Hz also). Since I plan to use 48Hz 95% of the time I will try to figure out 60Hz later (maybe tonight). Only had a few minutes of screen time and it is still daylight so I can only give basic impressions. The picture is super smooth, very non digital, and film like which is what I like about DILA. It seems to be a fair amount brighter (off axis) than my G11 but since I changed to a HP screen it is hard to tell. Can't wait until I get home to night to fire up and test.
I will also edit this thread and add links and other info to help present (or there any others) and future HD10K owners.
Convergence can only be adjusted on a global basis, not in a zone manner as with CRT's. When you adjust R, G or B shift, you are essentially choosing the 'lesser of two evils'. The tech you spoke with was correct.
Being a fixed pixel display any convergence adjustments are the entire image, in 1 pixel increments, up/down/left/right. If the adjustment is available, this should yield a maximum mis-convergence of ½ pixel (if you're off ¾ pixel to the right, moving one pixel to the left should yield ¼ pixel to the left). If it is off more than ½ pixel, get a replacement (if under warranty) if it cannot be corrected.
There is some interaction with the room, depending on color. The light that can bounce back to the screen can change the white balance slightly. I believe the calibration is for the StudioTek 130 screen, a different screen can affect calibration.
This is not correct! William Phelps Optimization of this projector goes far beyond simple color calibration, as has been discussed elsewhere. The very small adjustments needed to compensate for screens which are not white or for room interactions, if any, are easily done with the user controls in the projector. The calibration is not specific to the StudioTek 130.
As I recall, the image shift is limited to vertical, and not too much. If you are experiencing keystoning, I would look to projector level, then screen, there is no keystone adjustment on the projector (useless anyway on a digital pj).
The HD10K-S (short throw version) of the HD10K exhibits significant keystone at the limit of lens shift, due to the lens itself. I find that the projector must be tilted, NOT level, to compensate. I have recently reported this to JVC; they were not aware of this.
This may also be true of the HD10K with the long throw lens, I have not tested this.

G'day! Way too long since I've visited your wonderful country...
I find with the HD10K projector that with large amounts of image shift it must be tilted to remove keystone. This appears to be due to the lens design.
Try running the image shift to the limit, placing the projector at the top of the screen, and tilting it to get the image square. It looks a bit strange with the projector tilted like this but it doesn't appear to affect the image quality.

If my statement was not correct, why do you mention color correction adjustments???? sounds like a contradiction to me. Field calibration is about white balance/grayscale, among other settings, and yes, they use the Studiotek 130 as a reference for white balance. Whitefield uniformity, gamma and a host of other things are, and can only be done with the factory software.
If in fact you are experiencing image distortion with image shift, I would seriously consider moving the projector to avoid any induced optical distortion of the image. At the cost of that projector, it is worth an optimal setup, not a compromise. It would seem to me, if you are experiencing image distortion through the lens, you probably are experiencing some focus issues too.

I have developed my own software and processes for Optimization of the JVC series of projectors. There are many reports about this including magazine reviews. In this thread the discussion of my "calibration" is far more than what you are used to, and I do not use "factory software".
I think you will find, if you take the time to actually experiment with the projectors rather than just speculate, that the suggestions I make for placement and tilt are not a compromise. It would be a compromise to place the projector in the middle of the room, positioned at screen center, taking up the best seat in the theater!
We see on average 10 projectors a week. I speak from practical experience and actual measurements. My customers can attest to the quality of the work I do.
So if i understand you right there is no differences between the JVC and the Meridian exept for the outstanding calibration that Mr William Phelps does...
If you talk to Meridian/Faroudja, they claim they have changed some of the programming in the projector, in addition to the WP setup. I would like to think that WP has consulted with Meridian/Faroudja to incorporate enhanced picture control.

William, I truly wish I had the opportunity to work with/experiment on the projectors. Unfortunately, I don't get the opportunity.
My recent, only exposure, was just a few hours to setup all the input devices on a DILA-1080pHD, (DirecTV TiVo, 2-DVD players and a laser disc player) in the DVP-1080. The only real issue was the off-white walls in the room, affected black level in higher APL scenes. And yes, my comments were based upon speculation under the premise that induced optical distortion from lens shift was not optimal. If I were to guess, I would imagine you are only talking about ½ or so of keystoning at the screen, which would hardly be noticeable distortion.
I don't think, in theory, I was off, however your experience, practical application and technique, has provided me (others too) with some education in the issue. Knowing that it works, it is now something that can be used as a reference.
I readily agree, your level of optimization is far from a basic calibration (ISF or not), just as a full setup on a CRT projector is nothing like a basic calibration.
I assume the Faroudja projector is "William Phelps Optimized" from the "factory" (my reference to "factory software"), and the JVC is or can be optimized by William Phelps, by appointment.
Can not get my projector to work with the Harmony 880 remote. Using the data base it has lots of commands that the projector doesn't have. However the main problem is it will not power on/off. Have tried to learn these but it doesn't do anything. It also won't learn the arrow keys but will learn all others (and from other remotes) so it is not my technique or the remote. Have tried 2", 1",.05", 3",5", 8".... and get nothing. By far the most important are the on and off because the 880 is useless without them. How can I force the 880 to learn or where can I get the correct profile for my projector. I realize it is a somewhat rare item but there must be a way for it to work.
Is there somthing about JVC's on/off/arrow commands that are not learnable or incompatable? Are others having problems with remotes and the HD10K?e
Does somebody have expirience about repairing broken HD10K?
My one fails at powering up, when i switch on the device everything seems to be ok but then the lamp goes dark, stand-by led flickers fast and glow stady when the fans hafe turned off. I opend the unit already to hav a look for bad caps but all seem to be ok. I changed the bulp but it wasnt helpfull.
I cant find any explanation to this fault in the service manual, the led-indicator tables doesnt describe an fast flickering standby led.
I guess i would need the "service software" for this device to have any chance with repairing the unit
After getting the power supply replaced on my Meridian MF1 (tweaked version of the HD10K) when I unpacked the PJ from UPS shipping, I saw vertical striping in the pictures below, which were not there previously. Reading about striping with the HD10K several users have said they found it to come from loose connections in the machine.
Normally I'd ship it back to shop (the Repair Shop near Atlanta) but I'm in VA and RT shipping is $300 and I think its the shipping and shaking that caused the problem. After talking to The Repair Shop I have disassembled the PJ twice and tried tightening all of the visible wire connections, but gotten no improvement.
QUESTION - Does anyone 1) know any other causes of the striping in pictures below, or 2) know which connections in the PJ are likely to cause striping? I'm happy to disassemble and try tightening connections I may have missed.
Thanks for your help on this - its an excellent projector when its working.
