It's not a dumb question. It seems like every manufacturer places them in a different spot. On the X500, it's on a sticker right beneath the 3D Sync port which is located on the back of the unit.

Which makes it amazing how very visible the brightness pumping of credits is.

Same for me: at 400 hours, the only times the DI becomes noticeable is during credits. It has never bothered me during regular video content. I am using autoiris2. Extremely happy with that...

What month do you guy's think owners of the 4910 will sell their used units to buy the next generation JVC's?

Thanks,
Tom

Maybe just a two month wait then. I'll be keeping an eye on the forums classifieds.

Thanks for the help.

Even better is the grin I get during a fade to black when I can't see my hand in front of my face

Would you guy's consider the 4910 a pretty significant upgrade over the RS55? If I were to purchase a 4910 now, it would probably delay the purchase of a 4k projector for at least a couple of years. The longer I hold on to the R55 the less the it's value will be.

If I can't slow down my movie collecting addiction, I may need to live with 1080p for financial reasons. If I had to choose between 4k or continue with 1080p and collecting films, I would choose the latter.

AVS has a special this month on the 4910. A free lamp is thrown in so I would likely have this puppy for years.

I have only viewed 4k at the theater and the detail is amazing. My 55 is obviously softer but it is detailed enough for me to live with.


Thanks,
Tom

When a person states their projector has excellent convergence is it before or after zone convergence has been applied?
I have to use fine +11 in areas. I am concerned it may be causing some type of distortion. A grid looks fine even a small crosshatch pattern. Does JVC's zone not distort the displayed moving image? Any thoughts are appreciated.

Before any type of electronic convergence correction is applied. For the fine convergence system, integers of 5 are the worst case scenario as far as scaling artifacts go. The closer to numbers that end in 0 are the best for scaling. So +11 isn't too bad. But I think this means that your native convergence isn't too great. I believe every 10 steps in the fine controls shifts the color an entire pixel. This means whatever color you had to shift 11 steps is off more than an entire pixel. I believe this is still well within the quality control limits JVC sets however. For someone to consider their unit having great convergence, out of the box native convergence (before you use the electronic convergence system in the menus) should have less than a quarter pixel of misconvergence and a "golden sample" ideally will only have up to one color being less than a quarter pixel off.

Just had my x500 installed and living it so far but the only issue I am having is on low lamp mode and eshift engaged I get a slight whine noise. Has anyone noticed this?

It should be based on out of box convergence, after warm up.

Mine was pretty much perfect, except for the bottom 1/4 of the screen having some blue mis-convergence. Could be CA. I used values around 10-12 to fix it. I looked at resolution test patterns and I could not see any noticeable loss. I'm sure there is some side effect but I can't see it and it is less objectionable than seeing slight blue at the bottom of scope movies at the border of the image and black bars.


To be honest, with eshift doing it's thing already if you're using it, I'm not sure how much I'd worry about the effect of using the digital convergence anyway.

The noise is the pitch at which the e-shift device is moving. That noise is completely normal.
