The image below is exactly how the 4810 looks next to the Sony HW50. The Sony is noticeably brighter and the Epson looks significantly brighter than the JVC.
The X35 in this review is likely a post-firmware update and would expect the same lumen output at the 4810.
Acceptable 3D brightness is a subjective topic which is why we provide the lumen output in 3D. For this comparison, the JVC 4810 was ~ 560 lumens, HW50 @ 1000 lumens, BQ W7000 @ 1100 lumens and the Epson 5020 is around 1400 lumens in 3D mode. All projectors @ 17 feet from my 142" 16:9.

I know for a fact that some stuff looks good on the JVC with a new lamp, but I guaran-freaking-T-u that the JVC ghosts, every non-DLP ghosts. Throw in the right content even on a JVC RS-46 and ghosting will be pretty bad, even on a new lamp. As that lamp ages, it will only get worse, there is no design difference to change this, and no non-DLP has been able to do this yet that I know of (prevent ghosting on aged lamps).
I understand some are happy with the newer JVC 3D performance, and it is perhaps a tad better, but to say any NON-DLP does not ghost is just ridiculous
. I've seen the Epson 5010, and although ghosting is 1/10th what the JVC is, it's still there at times. As the lamp on the Epson ages, the ghosting gets to about half of what a JVC was on a new lamp, maybe even close to equal on a really really old Epson lamp (but haven't seen it on a lamp > 2000 hrs). The Benq I have = 0 ghosting.
It appears that you and others are calling me and others that do not see ghosting, liars.
I know what I see and I see NO ghosting on my DLA-4810, with my eyes, under my conditions.
And I am not trying to justify my purchase to no one - I have no need to do that.
What is obvious is that Zombie and many others like an overly bright image (to my eyes)
Now if the Sony is truly 2x as bright as JVC in 2D and it is projected on 2.4 or 2.8 HP screen, then the image has to be unpleasantly bright (exaggerated BB type image).
Now if that is what one likes, then that is your choice, but it is not mine.
To me it would be unpleasantly bright and I would venture to say it would require me to put on sunglasses.
Remember, not everyone likes a blazing BB image.
Calibrating a TV or projector, always leads to turning brightness levels down from BB image levels.
I had to adjust the aperture to -15 to have a calibrated image that was not overly bright.
Again, please don't get me wrong. If you like that type of brightness, by all means use it
And this may explain why those that crank up brightness (looking to replicate BB) may be seeing ghosting on the JVC, while those that do not care for an overly bright image do not see ghosting.
As far as 2D brightness, all I can tell you is that the DLA-RS4810 is significantly brighter (with aperture at -15) than the DLA-HD250 I had previously, with both in calibrated 2D cinema mode. Opening up the aperture more than -15 started throwing off my calibration and to my eyes was brighter than it needed to be. No review I have seen of the HD250 has shown calibrated cinema mode output of less than 750 lumens. The 4810 is without any doubt, brighter than the 250, it replaced in my HT. Now if you want to call me a liar,that is your prerogative, but I know what I see.
The 3D mode is significantly brighter than the cinema mode.
I did not calibrate the 3D mode as I did not like it and thought the stage mode was more than bright enough.
So why don't we try to show a little respect for one another and not go around calling others liars.
All I was saying, is what I see in my HT, with my eyes, without disputing others, without making definitive statements and without calling others liars.
I have said all that I have to say and will not say any more. I have no intent to argue with anyone.
I just stated what I see, with my eyes, under my conditions.
If you all want to keep on arguing, go ahead.
However, I am going to get back to enjoying movies in both 2D and 3D (ghost free and flicker free), in my HT, under my conditions, with my eyes and not spend any more time in this thread.
Peace to all
