I would not want to sit farther back than 1.3x screen width, which would be 10.5 feet for a 110" screen. So get the biggest screen you can for that seating distance, 120" would be even better or move the seating closer (just IMHO).

Da-Lite HP screen so you can close the aperture to -15. Even on a brand new lamp, I don't find it too bright at -15 aperture with a 106" HP screen, though my projector is not mounted to get the full gain and it is near farthest throw to maximize contrast. You will be fairly close to my setup except I sit closer to the screen.

I sit about 13' back from a Carada BW 110" screen. Seems to be right for me. 120" wouldn't be bad for me either. I am not sure what bulb I have. I have 850 hours on it and did see significant dimming during the first 400 hours, so JVC sent me a new 003 bulb. My projector is 15' away from the screen. I am at -6 (high) on the aperture and am getting 16.5fl. Nice and bright for 2-D, 3-D a little dim. I rarely watch 3-D, but it is nice to have the option.
After a nice calibration, the picture looks amazing. I had a RS-1 before this. The contrast and sharpness is very much improved. I wish I could have stayed on low bulb as it is dead silent. Very nice projector.

JVC just blew me off when I contacted them about a bulb replacement at 1 year for a bulb with 500 hours that's too dim to watch. They simply quoted their warranty policy and offered a "One time courtesy" price of $340 for a new bulb. Now they don't even reply to my emails.

Obviously the original bulb design was flawed; they had to redesign it and are only willing to warranty a $500 part for 90 days as opposed to a 1 year warranty on the new model bulbs.
post #4174 of 4435
Wow, that is a shame (on the warranty of the bulb). My experience was a little different. No response to my first "claim" after about a week of waiting. So I submitted another one, and on that one I received a response within a day, and it was really easy. I had provided them with all of the details in my claim (including my phone number and mailing/shipping address). The just confirmed that they were sending a replacement bulb, when I asked if it was going to cost anything, they said no. Easy peasy...

That was back a couple of months ago on a projector that was just over 1 year old.

Now, I have my front row seats at about 12' (eyes to screen distance) from a 138" 16:9 Seymour XD screen and love it. I was afraid it would seem too big, or that my wife would hate it, but my whole family loves it that size. With 2 rows of seats, you can sit in the back row and still have a nice movie experience.

Now, I went with the Seymour XD screen because I wanted all of my front speakers hidden so that I could fit the larger screen up front. That meant a gain of 1.2 per Seymour's site (I've heard that it is less than that in real-world settings). I do NOT care about 3D at all, so I don't need a light cannon to get an acceptable 3D image. BUT, if I did want 3D or was fine with my speakers being in front (outside of the viewable area of course) of the screen, then I would go with some screen with 1.8 gain or there about. Some people have super high gain screens, but 1.8-2.0 gain mathematically would be great for my completely dark room.

Good luck.

How has your Seymour screen fared with ambient lighting?

First off, let me throw out this disclaimer, all screens look better in a dark (or mostly dark room), so I am by no means saying that it looks as good as when it is fully dark in the room, but it does fine. I say that but I also will mention that I am not a fan of ambient light at all, so I don't really get excited about a picture in a room with ambient light.

I had a Carada brilliant white screen in a previous theater and the Seymour does as well as that does if not a touch better. I don't know how it would do vs. a super high performance (2.0+ gain) screen or a grey high contrast screen though.

Sorry. I wish I was more help.

I know that many screen places will send you material samples. I had my 3 samples from Carada and my sample from Seymour before I made my choice. I wanted a picture as good as what I had before (from a screen perspective) but if I could get acoustically transparent at the same time, then I would be happy. I am totally happy with my Seymour XD.

I m calibrating my x35 atm and I seem to have some trouble with the grayscale calibration. I ve set the mode on USER and color temp on user1 6500k.
I have to lower the GAIN GREEN pretty far down to get a decent overall greyscale. More specific, my settings are now:
GAIN: R 0, G -28, B -51
OFFSET: R 3, G 0, B 10

I always thought/learned that you don t want to change GREEN bias and offset too much (preferable not at all)? If this is true, then I m way off this as you can see!!

I am I doing it wrong or not?
Thxz for input guys
post #4178 of 4435
Hi guys,

Did a quick google search but was unable to find the answer to my question.

I have high def cable box connected to my marantz av7005 pre to my rs45. I have 120 h since this this fall. Pretty pathetic. I've been so busy I've barely had much of a chance to appreciate all the improvements to my mits hc5500.

Sitting here watching nba playoffs and nhl playoofs and I notice that the picture seems to stutter..... not sure if that is jitter or jutter. CMD is shut off. I thought that would get rid of it but it still happens. Not often but enough that I notice it. What is causing it? Do I need better hdmi cables? Is it a settings issue on the pre or the pj?

Edit: watching wwe, sit coms, news, cartoons I don't notice a stutter.

Hi all,

Im getting problems with My JVC RS45. ITs been working fine for the past one year, however today the on screen menu is working but no video is going through. I changed to HDMI port 2 and still no pictures. The projector works and powers up fine but cant recognise any HDMI inputs?? has anyone had this problem before? if so any solutions?
post #4180 of 4435
Power cycle the PJ if you haven't already (unplug the AC power plug from the PJ when the PJ is off of course, wait 10 minutes or so and plug back in)

Does anyone have any recommendations on ceiling mounts for this heavy projector? I am also open to a diy mount.

Many/most universal mounts will not fit this projector.

Chief Mount for the RS45 as mentioned above is GREAT. I wasn't "fond" of the price compared to what I used for my previous (much smaller/lighter) projector, but these JVCs are large and heavy, and the Chief does a great job.

+1. The ease of fine adjustability with a screwdriver is really nice. The good news is that if you do change to a different brand in the future, you only need to change the one attachment plate. The whole mount doesn't have to be changed.

post #4185 of 4435
The Chief mounts seem like a great fit but I do have a concern with regards to my room. My room has vaulted ceilings and is 12' high, but the top of the screen will be at 8' high. I'd like the projector to be as close as possible to the top of the screen in regards to placement. With this being said, are there any mounts with extension poles that would work for this projector? Heck, I'll even consider a diy projector lift.
post #4186 of 4435
Chief uses standard NPT fittings so you can use any length pipe you want to make the drop. They have all sorts of products for this including angled connection points at the ceiling.

Sometimes it's easier to just give them a shout and let them walk you through what you need.

Are you able to mount it on the wall at the back of the room?
I did, went with http://www.chiefmfg.com/Series/WM1
Don't let the picture fool you (like it did me), this thing is a beast. They have models with longer arms too.

The back wall is about 19' from the screen, which is why I have opted not to place the projector there.

+1 on this. I just went to my local home improvement store and picked up a length that I liked. (Since both ends are threaded, you are somewhat limited to specific lengths unless you find a place that can thread a custom length for you.) I took it home, cleaned it up, lightly sanded it smooth, and painted it to match the mount. Worked great, looks 100% professional, and was really inexpensive.
post #4190 of 4435
Thanks for the mount suggestions!

With my projector being mounted above my screen, will a high gain retro reflective screen still work for me? Are there any good angular high gain screens?
post #4191 of 4435
Well fellow X30 / RS45 owners, I've encountered the dreaded premature lamp dimming. Over the last 70 hours or so of use I've had to open the iris and go to high lamp power to keep any sort of watchable picture, amazing how it has really fallen off a cliff in brightness over last dozen hours or so. I'm at 473 hours of mostly normal power use with a ceiling mounted unit with lots of open space on all sides. Next lamp I'm certainly going to try the high altitude mode for more cooling.

Question to you guys is, what is my best plan of attack to try and get a replacement lamp out of JVC? It was bought 3/3/12 so out of warranty, but I am under 500 hours and this is my first request for a replacement.

Any ideas?
post #4192 of 4435
I used the nice but firm method when I talked to JVC a while back about a lamp replacement. Mine exploded with around 700 hours. Not sure if a dimming lamp will get you a new one as I and many others had to take pics of the exploded lamp before one was sent. It probably depends which tech you get to handle your situation.

I know this is painful but STOP using your projector IMMEDIATELY. Once the bulb gets like this it is in danger of exploding. The clean-up mess and risk from mercury is significant. If it is dimming that fast, it likely means a complete blow-up is imminent.

Otherwise all the advice you had on being polite but firm is correct.
post #4194 of 4435
Thanks for the input guys. I opened the door and took the lamp out, the part number ends in -003 but does not have the metal fin in airway I've seen in other pictures. I called and spoke to JVC customer care, he said it is within the 2 year warranty and needs to be sent to their 3rd party repair facility for evaluation. If there is a problem with the projector itself and not the lamp they will repair and send back at no cost. If it is indeed the lamp it will be returned and he said to call back to JVC directly for a discounted "accommodation" lamp. Not what I wanted to hear at all. He spoke to a supervisor twice during my call as I pushed for a lamp to just be sent to no avail. I'll ship it tomorrow but I can't imagine it is anything but lamp knowing what we do about these series of projectors.
post #4195 of 4435
Here is what I did, and I recommended this to someone else here recently and it worked for them too:

I used this link on their "JVC Professional Customer Support" web site:
http://pro.jvc.com/prof/support/index.jsp

And then I not only selected the "E-Mail Support Request Form" option, but a few days later I followed up with a direct email to: proinfo@jvc.com

Worked for me and mine was several months past the 1st year, but I too had less than 500 hours on the bulb and it was dimmer. Not "dropped off the cliff" like you are explaining, so not even THAT bad, but I was sent the replacement bulb pretty painlessly. I did mention that my projector was calibrated (which it was, by me) and I gave them the lumens from calibration originally and at the point in which I asked for a replacement. I don't recall the numbers, but it was enough "on paper" to be dimming too early for less than 500 hours.

I just did the above and all of a sudden received an email from JVC that they were taking care of it. No cost, no hassle, and no sending the projector off for some undetermined length of time to be "evaluated." The replacement bulb does have the little "fin" and is working great.

Good luck!
post #4196 of 4435
That was about the same situation for me. I gave them the lumens I had measured new and then the gradually, too gradually, drop. New lamp on its way. This was after only 5 mos. of ownership though.
post #4197 of 4435
Quick question.

What is the current best low cost way to get 3D on the RS45? I saw a new JVC PK EM1 emitter on eBay for about $43, but no glasses. I know that there were all sort of more preferred (and lower cost) options than JVC glasses in the past.

Thanks!
post #4198 of 4435
Just changed my bulb on my 45. I was at 1000 hours and was down around 14fl. I had a spare lamp. With the original bulb, I was at -15 on the aperture and getting 16fl. With this bulb, which does not have the flapper, I had to go to -4 on low to get 16fl. I have a Colormunki, which I don't know how accurate they are for measuring brightness. There is definetly a big difference in lamps. Both are OEM. The spare came from JVC because I told them how fast my orignal lamp was dimming. I had to switch to high lamp at around 400 hours. I am only lighting a 110" Carada BW, throw is at around 15'. I just hope this lamp lasts the 1000 hours the other got. I am thinking no.
Is there a place to just get the bulb rather than the whole cartridge? It looks easy enough to change.
post #4199 of 4435
So I just set my new RS45 up and over the past few days I've had a few shut downs and some no picture errors. The firmware is the latest. The one error was no picture and just a green blinking standby/power button. The other is the unit shutting down with solid red warning & standby/power button and a blinking lamp button. Just picked this up from AVS and wondering if it's normal to start off like this or should I expect better. Picture seems fine, and I just got through half of the Avengers and some Netflix with no issue after experience both issues after I finally got it mounted. I figure I'll see what happens after the next few uses.

The first time I started it up for a few while it sat on the center piece of the sofa it worked fine, and when I thought I had turned it off it apparently wasn't. Walked in the next day to see some Matrix like green laser like grid pattern on. Had to pull the cord. After that I waited ten minutes and restarted only to get the lamp error mentioned above.

The chief mount is solid by the way. Easy to setup, and I picked up a 12" 1.5" pipe for a few dollars at Lowes so I can return the Chief one I bought.
post #4200 of 4435
I am with a friend who got a refurbished unit (rs45u) from JVC with a new lamp.
We are trying to calibrate the basics for now but i can't seem to set the contrast.
Brightness - no problem.

I am using the Spears & Munsil HD Benchmark and Calibration Disc 2nd Edition BluRay disk with the oppo 103 and no matter how i reduce/change the contrast values i can't see any black around the numbers, the background around ALL numbers are completely white.
iris - (-15)
lamp - normal

Am i doing something wrong? can the projector have a problem?
