Maybe that is why some get less ghosting?

My first RS40 had serious misconvergence. It didn't affect the ghosting at all. Convergence errors are too small to make any difference.

Joseph - I setup a friends 106" 2.4HP Cinema contour tonight with the Sony HW30. My 142" 2.8HP is noticeable brighter with the same exact projector. It's remarkable how much gain the 2.8 has, I believe some have measure it well over 3.0 with actual tests.

If anything happens to my screen, i'm out of front projection until the 2000+ lumen projectors @ D65 are under 10k.

It's really a shame they ended the 2.8HP run, right on the dawn of the 3D front projection revolution where a 3D projector and the 2.8 IMO are a perfect match.

Yes, it's too bad. The DaLite HP 2.8 is the only piece of home theater gear I've never wanted to upgrade. Projectors, AVRs, disc players, home theater PCs - I change them like socks. My HP? Not a chance.

Are HP's out of the question for top of screen or slightly above projector mounting? How about brightness uniformity with that type of screen?

Hi Ron, I remember contacting you a lot when I was about to choose my screen. Based on my setup and budget, I was ending up with Da-Lite 1.3 Cinema Vision,, so many thanks for information and recommendation

I'm currently at 140 hrs and every movie I watch I fell in love more with the projector. I was watching Shrek 4 yesterday (in 3D) and my friends were very impressed of how sharp and vivid the image was. Anyhow, this is my dummy questions:

-Normally how much the high power mode will affect the lamp life (vs normal mode). I'm fine with normal lamp for 2D but sometimes I wonder what is the affect if I use the high lamp mode all the time. I'm planning for having the lamp at least for 1200 hours!

-Will we notice any improvement wearing the new 3D glasses?

-Is it Ok to keep the projector running for about 6-8 hours,,, Star Wars and Jurassic Park are coming

Just my opinion, but I would not go with a HP in that situation. Brightness uniformity depends on where you sit. At the key spots close to center of projector its great, but off to the sides the uniformity gets worse the further you go out. I would say at the center spots, my ST130 and HP are even as far as brightness uniformity, but off to the sides the 130 was better. Overall my 1.3 screen was/is better in this area.

The farther your eyes are from your projector's light path the lower the gain you'll see from a High Power. The HP 2.4 material has a more relaxed gain roll off as you move off axis compared to the old 2.8 so it still might work in your non-ideal situation. Run your numbers through the following screen gain calc and order a fabric sample to see if the HP would work for you.

Dr. Mark's HP 2.4 screen gain calculator (post 566):
http://www.avsforum.com/avs-vb/showt...213577&page=19

The High Power thread:
http://www.avsforum.com/avs-vb/showthread.php?t=773065

Even if you are so far off axis that the HP gain is equivilant to a standard 1.3 gain screen you still may be better off with the HP. That's because projectors come & go while a good screen can last forever. Your future projectors may accomodate a more optimal mounting location for the HP. If you get a 1.3 gain screen now your future projectors will be gain limited compared to the HP.

I haven't noticed significant brightness uniformity issues with the HP 2.4 even well off axis. I doubt it would be a problem. Check out the High Power thread for more opinions on that concern. (Keep in mind that the old higher gain 2.8 fabric has more uniformity issues than the 2.4. If you read comments on that topic understand which material folks are referring to.)

Not sure if this has been discussed, but do you guys ever look at the JVC 3D glasses when the projector is off... Do you see it slowly alternate between each eye on and off? Not sure if this is what has always happened, didn't notice it before, but it seems to do that now. My xpand set doesnt do that, but then again it has a manual power button.

Ana/Ron,
Just one slight correct on Ron's reply about the new JVC glasses. They are actually the same as far as technical specs, they will not offer less or more ghosting. The key with less ghosting on the RS45/55 is that the 3D synch driver will now allow for the active shutter glasses (whether it's Xpand or new or old JVC glasses) to stay open longer based on synching signals, so the right eye will stat open longer, then the left eye will stay open longer. This is not caused by a mechanism change in the active shutter glasses or IR emitter, but an actual change or improvement in the driver within the new 2012 projectors (45/55/65).

He is 100% correct about this. I sold my 2.8 HP a few years ago as I packaged it with a projector that a friend bought, if I would have known they were going to quit making the 2.8 material I never would've sold it as like Zombie earlier said is alot brighter than the 2.4 material. The one positive like Henrich just stated is that the brightness doesn't drop when you get off-axis as much as it did with the 2.8 material so it does allow for you to mount projector in the non so-called sweet spot and there aren't any sparklies or brightness uniformity issues. I think I may have just said exactly what Henrich said but wanted to say that I have experienced exactly what he said in regard to the 2.4 HP screen especially vs the 2.8 HP screen.

One other note. Just as a test a month ago I put back up my 1.0 matte white gain screen to compare to the 2.4 HP and it was a night and day difference. The 2.4 HP does add so much to a picture and after you have it for a while you almost take it for granted until you see what it is like without it. I like a bright punchy picture and wouldn't think of using my RS40 without the HP screen.

Makes sense. My comments were in relation to the 2.8. While uniformity may be better with the 2.4 as you move off axis (I would agree with this from my experiments with the 2.4 material vs my 2.8) it is also significantly less bright unfortunately. Surprised they dont still offer the 2.8

Mike,

I agree. Even with my minor complaints I cant imagine going back to my 1.3.... I am spoiled with the brightness/ punch of the 2.8

I spoke to Dalite's Marketing VP last year and let her know how sad it was that they discontinued the 2.8. She told me it was because they couldn't source one of the materials necessary for making the screen.

I have no idea if this is true or not, but that 2.4HP I just setup last night for a friend isn't just .4 gain dimmer than my 2.8, it's quite noticeable since I am so familiar with the 2.8HP.

Jason,

Yeah, its almost like the 2.8 HP should be rated a 4.0 gain and the 2.4 HP rated a 2.0 gain. There really is a huge difference between these 2.

It really is a shame the 2.8 was discontinued considering we are at a point where the 2.8 is needed most with 3d and the low lumens it brings.

I found the same thing as you guys did as far as the brightness. I received a 2.4 sample back in Jan that I wanted to compare to my 2.8 and there was a noticeable/significant difference comparing the 2 from my center seat. As I moved over to my far seats, the 2.8 was still brighter, but it was not as big a difference vs my center seat which goes to show the 2.4 does not drop off as fast. In my normal center viewing spot though there was quite a difference to my eyes and more than the supposed .4 difference the specs would suggest. On top of that, I found the 2.4 material to be much flimsier and more prone to screen wrinkles which drive me nuts. Even my 2.4 sample piece arrived with a few wrinkles.

I didn't realize that. The 2.4 material seems paper thin in comparison. I have a sample so I'll try it again or just keep what I have then.

Yep, it is thinner and I can see a few wrinkles every now and then myself which like you drives me nuts. I was thinking of getting a fixed frame 2.35 HP screen to eliminate the wrinkles but the difference in price is too much. Hopefully they will come out with a new material that is a little higher gain and thicker so its the same brightness as the 2.8 screen and zero wrinkles.

Does anyone know if the vertical stretch on the RS45 is the same as the RS40 (80%)? I have a CIH setup and need to figure out if the projector will work for my situation.

Also, any owners willing to give their thoughts about the RS40's frame interpolation (for those who actually like frame interpolation, seems to mostly be a love or hate thing).

I've never met a frame interpolation that I liked.

It's on my two Samsungs, my Panasonic 4000 and the RS40. I try it for a while, get frustrated with the inevitable artifacts and turn it off. I'd rather live with low frame rate judder, and I hate low frame rate judder.

I am having an issue tonight with my RS40. I watched a movie last night, turned off the system as usual. I had a weird random noise image that popped up on the screen after power on. Then it hung on HDMI 1 FOREVER and would not accept a signal and would not display an image. I am assuming it is the projector as my processor was playing sound. I tried once to unplug for 1 min, but now am about to try unplugging for awhile longer.

Any suggestions?

The only thing "special" about 3D mode with regards to the lamp life would be that it puts it into High vs Normal lamp mode. So, what you're really looking for is information on High vs Normal in general, not necessarily whether they used 3D mode.

There are electronic driver circuits as well. This probably isn't a firmware mod.

Could I ask those folks who were experiencing the X3 "lock ups" what was the eventual outcome?. Did a firmware update fix the issue or was the projector eventually repaired or replaced?. The reason I asked is mine has just started doing it and its a real pain! It has the latest firmware(for Australia it's V3). Thanks for replies.

Side note -- are there any 3rd party glasses that are lighter weight, cheaper and work just as well ? Both the JVC and Xpands feel heavy compared to a friend of mine's LG 3D plasma glasses....

We remodeled our dedicated home theater over a month ago, replacing our 8 year old Runco VX-1000C (which played without no down time for 8 years) with the JVC RS-40.

Have watched several 3D movies and about 20 Blu-Ray and/or Netflix movies, in addition to Directv programming. We also repainted, installed new carpet, new ceiling moldings, baseboards and motorized leather recliners.

We are very impressed with the overall performance of the RS-40. The picture is awesome.

I'm in the same boat as you. My X3 has been randomly freezing on the "D-ILA" boot-up image. It won't respond to remote or hard button commands. Unplugging...waiting a while...and powering up again often works. I've just contacted my dealer for advise. Any info from those on here with further insights would be greatly appreciated.

BTW, I'm running the latest firmware as well. Cheers.
