The CMS built in is not all that good compared to an external CMS. If you are going to own your toy until it breaks from old age, buy the better one. You are spreading out thje cost over a longer period.

I don't know if it has been mentioned in this thread or not, but it seems to me that the motion problem I saw with a rs40 is either gone or at least greatly corrected. Some discs that were unwatchable on the rs40 (star wars ep 3 and the last transformers) were pretty darn good on the 4810. At least the small sampling of the discs that I watched were. I am trying to not put any hours on the projector until AVS works out a return with JVC over some of my projector's problems.

.They are the same except the 4810 has a three year warranty instead of a two. Call me if you want the answers to your other questions. I will make certain folks at JVC and AVAD angry if I post them here as well as pissing off certain phone order discounters of JVC.

What motion issues are you referring to? I've seen many things discussed about JVC projectors in the past: motion blur, dithering noise, banding/posterization, color trails/fringing, etc.

Haven't researched it enough to know or care about the exact terminology but, when I watched Star Wars 3 or Transformers DOTM, or certain satellite DTV shows like Grimm there was a certain jerkiness to the picture that made them unwatchable. Kind of like frames were being dropped or lost as the action unfolded. I don't know if this is motion blur or what it is, but it was horrible. The 4810 picture is much smoother with no jerkiness. Maybe I had a bad sample with the rs40, I don't know.

Is CMD off or on? How about on the RS40?
post #667 of 1794
cmd off on the 4810. tried every motion setting on 40 to no avail

can somebody please tell me the 3d performance of 4810?

Im currently looking for a dlp 3d projector to combine with my 4810.The 3d of the 4810 is so bad it gives me a headache.

do you mean picture quality of 3d or the problem is active shutter system?

the active shutter system.the picture quality is ok.I use to own a acer 9500bd dlp projector and the 3d picture was great but too dark.

thank you my last question can you tell someting about its brightness @3d and ghosting/crosstalk performance

happy new year

. It's bright enough on my 130inch 1.0 gain screen with the crosstalk cancelor slider at 0 but theirs more crosstalk visible.If I move slider to -8 it improves ghosting but at the expense of brightness.If you want a do it all projector you should consider the Sony 50es.
post #674 of 1794
Hi All, If anybody has had a chance to compare, how does the PQ of the 4810 compare to the 56? I'm asking because I'm ready to upgrade my projector, and could get a 4810 right now...but if the 56 is worth the price difference, I may consider it.
post #675 of 1794
Quick question guys!

What kinda 3D glasses do you recommend besides the factory RF glasses? Does the Xpand & Monster glasses work out of the box? Are they IR or RF?

Thanks in advance. smile.gif

what about 3d performance?
post #678 of 1794
Check Zombie's shootout thread and comparisons. Best comparative reviews on the entire internet for what we are interested in..... for $10,000 and under projector technology. For the parade I was watching in 2D.

On a related note, are the JVC glasses better/brighter than the aftermarket glasses? Are the JVC's worth the extra money?

Does the Sony 50es have lens memory or I have to zoom every time I have a 2.35 movie? Btw my screen is 2.35 140" one.

The Sony has a manual zoom, so no lens memory. The zoom range isn't as large as the JVC, so check carefully that you'll be in range for it to work in your setup. For me the image would have been too big for me to use my A Lens, so I had to cross it off my list. frown.gif

This topic is more complex than most new JVC owners may think. It first came up two years ago with the introduction of JVC's first generation of 3D projectors (e.g., RS40, RS50, X3, etc.). The JVC projectors put out polarized light with all 3 colors (red, blue, green) aligned horizontally while the JVC active 3D glasses include a polarizing element (as part of the liquid crystal lens) that is also aligned the same direction. However, just about all other brands of 3D TVs and projectors use active 3D glasses with their polarizing element oriented vertically. As a result if your projection screen does not retain the polarization of the projected light then compatible 3D glasses, such those from Xpand, will work OK, but if your screen does retain a significant amount of the polarization then tthe non-JVC glass will lose more light than the JVC glasses resulting in a dimmer image for the viewer. HERE is a link with a lot more details.

Sorry for the dumb question but here goes...the Pixel Adjust On/Off menu setting doesn't behave like I'd expect. Rather than toggle the convergence adjustments on and off, the setting just turns the ability to make adjustments on and off. In other words, even with the setting set to off, existing convergence adjustments remain effective, but additional adjustments can't be made. If you want to turn existing convergence adjustments off, the only option I see is to reset them. Then if you want to turn them back on, you'd have to re-enter them all.

Am I missing something here? Is there a way to toggle the convergence adjustments on and off? This seems like a firmware bug if you ask me.

JVC has improved the CMS performance this year and how it works within the projector. So you should see better results than with previous models.

Yeah, It's just too bad for several us that Green is undersaturated with a hue error (with the RS4810).

Hi Kris ,
That's encouraging information , can you elaborate on what has been improved ?
Have you had a chance to test any of the new JVC Models yet ?

post #687 of 1794
I've seen the green error. The X55 I have here had a hue shift that couldn't be undone without killing saturation. So I had to find the best compromise between the two (which ended up quite good). The X75 I have had nearly perfect colorimetry for all colors and no issues at all with green.

JVC did some tweaks to how they handle the CMS that makes it better this time around. How it interacts with the other adjustments has been changed.

Also, if you want to get a fairly good calibration without as much fuss, don't mess with the basic picture controls (brightness, contrast). If you change them it messes with the rest of the settings and makes it very difficult to get right (gamma, grayscale) because of how JVC handles the math. You're better off leaving the projector in HDMI standard and leaving contrast and brightness both at 0. Obviously this clips above white, but pick your poison.

Yes, I fiddled around and minimized the error as best I could. ∆E is a tad high at 100% saturation but acceptable at 75%. My unit also has a huge Cyan undersaturation (the green under saturation doesn't help this obviously). One poster commented that his lowest green error was with film mode and film CP. I didn't try that particular combo but will next time I calibrate. Do you recall which mode and color profile you tried?

Could you elaborate on this a bit? I didn't see any gamma/grayscale issue using HDMI Enhanced (brightness -7, Contrast 13) and it calibrated beautifully with these settings.

BTW, I'm also curious if you've seen gamma fluctuate at the higher levels. It appears that 100% Y is fluctuating thus causing gamma to fluctuate. I can't see this with real content but it's sure apparent with the test gear. I'm hoping this settles down some as the lamp ages.

Thanks for the link and the info Ron. My screen is listed as a material that retains little or no polarization. If I understand everything correctly, then I should be able to use any of the Xpand and other aftermarket glasses with the 4810, since the orientation of the polarizing element won't matter with my particular screen.

RS 48 just showed up, got a great deal..... finding a mount was not easy.... now waiting for my calibration, next Friday!
