I assumed it would show some. I'm wonder how much it will strain my eyes this year. JVC 3D really makes me sleep good. It took me about 5 attempts to watch Alice in Wonderland. Matter of fact, I don't think I ever watched it from beginning to the end.

Hi Kraine,

Has the ghosting improved significantly or just slightly from the 45/55/65? Also, how does it compare with the other new projectors you have seen such as the Sony 50?

Thanks!

For zombie10K, the X55 (JVC) has now 5 levels of MPC (E-Shift, the pics show the different names of them). I have use the HD level for the Bond Pic. My little review of the X55 will be online next week, expect some surprise especially on the Brightness level.

Kraine...

what is the Max lumens calibrated in 2D?

This is super important to me with my 150" wide .96 gain AT screen...

I have an RS4810 on order and need to make sure it will work for me.

Hi kraine
I am also intresting to know the brightness co apre to x70 and the flicking, ghosting issue how much JVC improved.
Most important is the e-shift2 compare to e-shift1.

This tells us nothing...

At 470 lux what was the image size?

At 144 lux what was the image size?

Iris full open?

We need lumens, not lux.


Or we need lux and a lot of extra information.

Posted this over on the Sony 50ES thread but maybe it's more relevant here since this is where kraine posted the JVC L/R images from cinetson.org... so apologies in advance for the duplicate post.

I took the liberty of placing kraine's shots of the L/R 3D images on the Sony VPL-HW50ES next to the L/R 3D images on the JVC RS48/X55 from cinetson.org (audiovideo.fr). I couldn't access the L/R images for the Sony VPL-HW50ES from audiovideo.fr as their site seems down right now.

Of course, this is by no means a scientific comparison, since nothing is controlled for (brightness, glasses setting, etc.).

But it seems to me that the JVC is holding up pretty well in terms of ghosting in this pattern:



Full-size image here: http://cl.ly/K9gB/JVC_vs_Sony-3DGhosting.jpg

Of course if the Sony image is much brighter than the JVC (as kraine is claiming, I believe), then this is an unfair (for the Sony) comparison.

The rollseyes makes me think those aren't that great but please give us some context - those numbers don't mean anything without something to compare to

I wouldn't worry about it at all. The real test is when everybody gets their order in December. Brightness shouldn't be a problem, but we'll see.

Might be a dumb question but the Sony looks brighter but a bright blue color is this because of camera flash or something ?

taking the photos behind the glasses can be a challenge, the shutter timing of the glasses and camera exposure can cause it to appear like that in the screenshots. It's not what your going to see in person.

zombie10k: Don't know if you saw this over on the other thread, but I was wondering exactly what your shutter speed is when you do these comparisons. My feeling is that if you stopped down the lens or used a ND filter & exposed for long periods of time through each eye of the glasses, you'd avoid artifacts. See my post: http://www.avsforum.com/t/1420975/official-thread-sony-vpl-hw50es-new-sxrd-projector-ifa-berlin-2012/210#post_22490533

After filled the side of the screen and after calibration in low lamp mode 387 lumens eek.gif

and in high lamp mode 569 lumens

The lamp as 18 hours.

It's definitly less then the HW50ES in the same condtions.

Something is wrong with your unit I think. No way can the lumens be that low. No doubt the final units should be much brighter.

Yes I remember that every told be the same after my firts light measurements of the JVC X7 and after a while end users discovered that there was some lamp issues frown.gif I can only comment what I measure and you're right for a almost new lamp those level of brightness are a bad sign.

Nevermind my earlier questions about shutter speed of camera for the images attempting to measure ghosting.

It seems from the EXIF data that the JVC shots were taken at ~1/8s, & zombie10k's shots were ~1/15s for the HW30 shots.

That's much longer than 1/120s or 1/240s or even 1/24s. So neither of these images from kraine or zombie10k should be subsampling the interval of when the shutter is open for L or R eye, meaning the shots should average out any delays in liquid crystal switching that might otherwise register if you sampled a duration shorter than the entire length of time a shutter may be open for either eye (1/240s for Sony). The longer the shutter speed, the more averaging you do, & the less the chance of such an artifact.

Point is the testing methodology seems sound in which case it seems like the JVC is holding up well.

Thanks for the tests guys.

I agree, everyone should just rush out and buy one and forget about online reviews as this is just a minor quality control issue and with jvcs recent history, will undoubtedly be fixed rolleyes.gif

That is very concerning...

One more review of low lumens and I will have to cancel my Pre-order. frown.gif

I hope the longer lasting slower dimming lamp is not because it's been pre-dimmed.....rolleyes.gifeek.gif

I also noticed that the colorspace is undersaturated which is contrary to JVC's statement that they will be wider this year.

KRAINE,
Which colorspace did you calibrate?
