I have a question about the DI, when I calibrate the x500 (4910), should I keep the DI on all the way or turn it off when calibrating the projector Then turn on after then. I never own a projector with DI, x500/700 might be my first projector with DI.
I plan to upgrade my X70 to x500 or x700, I already sold the x70.

That was me that posted on avforums but I didn't say it was much better!
I mentioned that the eyelashes didn't thicken as eshift 2 had issues with thickening fine lines. Doesn't mean eshift 3 is better. Still a lot more looking and comparing to be done.....

Sorry about that, guess I got excited. I edited my post and took out the claim part.

I just did krichter's bright corners test (see the RS57 thread) by holding up an index card in front of my RS4910 while it was in "Hide" mode! Eeeekk! It was a kaleidoscope of color!! Don't do this test if you value your sanity -- I bet even if you didn't have visible on-screen bright corners you'd see something while doing this test. It's a good thing we don't watch these projectors on index cards one inch from the lens! wink.gif

As I said, I do have visible bright corners on my 4910 but they're not awful and the only time I'd ever notice them in real viewing is during fade-to-black scenes -- if there's anything else on the screen the bright corners are invisible. It was pretty much the same story with my 4810.

Thanks for your response. Having a DI on a jvc projector is the moment many of us have been

However, it seems to me that the lower your manual iris setting, the darker the APL of the image would have to be for the iris to even do anything. In other words, my iris is manually set to -12, so the APL at which I can see the iris moving (if I look at directly the projector) is pretty low. It does seem to do a good job of dropping the black floor on darker scenes though.
waiting for. Can't wait to hear how the 3d is.

Just got back from picking up my new X500 from Santa's sled which had been running behind. It is replacing my former X55 which had 950 hours on the clock within six months.

Hmmm, should I open it? Yeah, I'm gonna open this sucker up and join in the early owner festivities (or pain, heaven forbid).

I hope I like what I see!

I have just joined and read this thread...my 4910 will arrive at Accucal on Monday for calibration. I am SO excited. My current projector is the RS-50. New will be Eshift (50 had no Eshift), 2D to 3D conversion (well, it will be interesting anyway), new bulb style, Iris, 3 generations of newer panels, brighter picture, and other improvements in the 3 years since the RS-50 came out. I couldn't afford the RS-57 if I wanted calibration, so I went with the 4910, but I still think (and have been told) that the 4910 will beat the RS-50 in most aspects of the picture. The RS-50 had a native contrast of 70,000:1 now I will have 60,000:1 but I don't think this will be anything I will notice much. Everything else has been improved.

I first owned a Sony projector, then went with the original Epson 1980, and then the RS-50. But this will be the very first time I will have calibration done to the projector. I hear so much about it, I am pumped!

I have to wait until it arrives on Wednesday, it's going to be one of those really long weekends and Monday and Tuesday, ugh. I spent some time this week darkening my theater room. I covered the seating in black fabric and painted the ceiling much darker.

I am hoping during the weekend we will get more input from those who already have theirs, but alot of it has to do with everyone's different eyesight and different screens as well. I am using a Da-Lite 2.4 gain 159" screen, so an image that size I am looking forward to the increase in brightness.

Does anyone know why JVC has not been able to increase the lumins on their projectors to a larger degree? Epson is claiming 2200 on their new projector.

Epson claims 2200 lumens but you won't see anywhere near that in a usable mode that gives accurate colour performance. JVC have had a 1700 lumen projector out for quite some time, a brighter version of the current x-series chassis. The extra lumens comes at the price of noise andcontrast which is reduced by at least half for less that a 50% increase in brightness. Its called the F110 or something like that....

I just looked at the specs for the 110, contrast 30,000, half of the 4910. I will be happier with the darker blacks.

Yes - and thats 30k max. You could be in the 4 figure contrast numbers if your shooting for those 1700 lumens (maximum zoom, aperture open) 4 figure contrast and all of a sudden, your native contrast is in amongst everyone else and you've lost your 'ace' card. Thats why JVC haven't went down that path is my guess....

HDMI 1 did not work sending a native 4K signal. The projector didn't recognize the input. 1080p worked fine.

After the box booted up and sent 1080p, I forced it back to 480p and again the projector showed those artifacts.

HDMI 2 nothing works at all. It basically gets no signal no matter what is fed to it. I take the cable which works in HDMI 1, move it to 2 and change the input on the projector and black screen. Normally when I plug/unplug an HDMI cable the sound from my receiver stops a bit while it does the handshake, but plugging and unplugging from the second port doesn't do that. It appears the HDMI chipset on my projector was dead.

The picture was great otherwise in 1080, but it's going to have to be sent for an exchange which is unfortunate because I was going to use it for a new years party.

Just to confirm, what HDMI cable are you using? Is it a directional HDMI cable?

Hi,

I just received my 4910. I have temporarily set it on a table and hooked it up to our Dish Hopper. I adjusted the focus, shift and zoom and it looks great compared to my Panasonic Ae900u. I went through the manual twice at a quick speed. I have noticed that lines are not straight. I turned on a football game and the further to the side of the screen, the worse the effect and in fact the side edge of the picture is bowed inward. Can someone advise if this is simply an adjustment that has escaped my mind or is it a flaw??

I don't believe so. It is a Monoprice cable from the last owner of the house who had it installed through the wall.

 

On the shielding it reads "E139956 (UL) TYPE CL2 SHIELDED 22 AWG AWM 20276 80 Celcius 30 V VW-1"

I am also having handshake issues with the HDMI ports. I fought to get 1080p to work last night and watched a few movies.

Today, I can't get anything to display over 720p on either of the two ports. I have tried two Redmere 30 foot cords and several 5 foot or shorter cords from various vendors.

With the cords, I tried using the following as sources: DTV, Sony BD Player, and a DENON receiver.

Sadly, I exceeded my time limit to return because it actually work for a little bit of time. frown.gif

I have noticed that my 4910 takes longer to lock onto an HDMI signal -- sometimes significantly longer -- than my 4810 did. However, I'm using an Iogear wireless HDMI system and recently added a Darbee Darblet so I figured the additional delays were due to the Darblet. The 4810 was never particularly quick to sync, but I think this was the Iogear's fault. Also, my Onkyo 5008 has never been particularly speedy about locking on, so given all the dodgy devices I have in my signal chain, it's tough to pin down the culprit of HDMI signal issues.

Having said all of this, the 4910 hasn't yet completely failed to lock on...it'll eventually get there. Hopefully if there are common HDMI issues with the new JVCs they can be quickly fixed with a firmware update.

I was able to clear up my HDMI issues with the following.

1) Factory Reset of JVC - Then turn off
2) Unplug It
3) Call AVS Guys wink.gif
4) Plug in - Fixed

So, the first 45 minutes of viewing HD satellite video off my Dish Hopper was looking pretty good while I went through the settings.

Then I switched over to the PS3, popped in a Blu-Ray and then I experienced an apparent HDMI handshake issue as the disc attempted to play. CRAP frown.gif

I then tried to switch back to satellite and got the half and half scrambled screen shown in the attached picture. Still troubleshooting...

Yes, we checked about half a dozen. Here are the preliminary results:
(All measured with minimum throw distance and Iris open)


- Maximum brightness : Between 1200 and 1300 lumens , 1240 lumens average

- Brightness calibrated : Between 940 and 1100 lumens , 1050 lumens average

- Eco mode : Approx -30 %

- Contrast native / calibrated : Between 26,000:1 and 30,000:1 , 27,500:1 average

- Contrast Dynamic: Factor of 13 , between 300,000:1 and 400,000:1

- Gamma: Perfect factory Gamma of 2.2 for all devices. Shadow Detail could use a bit calibration.

- Color temperature : Good presets, can be optimized a bit further

- Color space : Best preset is "Custom 1 " BUT : Not all X500 can be calibrated perfectly in green.
Some have a yellow cast in green, which you can not fully correct using the CMS:





Some X500 have this green-problem, others not. So you need to be lucky.

Ekki

Thanks Ekki.

Something that stuck out:

"Contrast native / calibrated : Between 26,000:1 and 30,000:1 , 27,500:1 average"

That's interesting. The 500's are advertised as being 60,000:1 native contrast. Haven't you measured JVCs to be much closer to advertised native contrast in the past?

Also: Any HDMI handshake issues to report, like so many others here?

I noticed that as well, but I just assumed (?) those contrast readings were taken at minimum throw and long throw would get us closer to spec.

Oh I forgot to mention:

All contrast values measured above with minimum throw distance and Iris open.
Contrast increases with longer throw distance and Iris closed (but therefore brightness decreases)

Overall, you get about 10% contrast more than with the X55...

HDMI handshake Problems did not occur.

What exactly does this mean,and how do you check to see if your unit has this problem?

Is the green calibration issue the same as what we saw on last year's X55 / RS48 / RS4810? it sure looks like it judging by the CIE chart you posted.

I had planned on placing my X500 16feet back from the screen, it will be on a shelf and positioned at vertical center.. It sounds like that may be to close? My room is totally black and my screen is a 115in reference 4K 1.0 gain fixed screen.

That should be fine. Mine's about 13-14 feet back from a 110" 16:9 screen.

I had the same issues and was able to reset the handshake issue.

The problem arose when my dtv box switched resolutions automatically. After the problems started, changing sources and or inputs did not fix it. In fact, the more things I tried seemed to make it worse.

Please try resetting and unplugging. Hopefully that helps.

Got my 4910 today, hooked up and configured no problem (coming from 3 DLPs, 1 Sim2). Watched some mixed content for a couple hours, no problems with synch on either HDMI, no iris pumping though I've watched no torture test scenes. Convergence is very good with red only a half pixel low, coming from a single chip DLP, there's a negligible difference between the sharpness of this unit and an average single chip DLP. Brightness measures an average just short of 1070 lumens on 106" screen from 14 feet (lamp high, non eco, DI#2, 6500, Cinema). I don't really see any advantage to e-shift3, I A-B'd quite a bit on DirecTV HD and Blu-ray...I saw a smoothing effect with some BD material, generally, DTV was softer with it on than off. Just my opinion...
