Doesn't seem to. Just when the 3-D is engaged.

Saw someone else mention a calibration thread..... I can't seem to find it
post #2163 of 4435
I'm wondering if the lamp fade has improved at all in this year's models.

If anyone already has a couple hundred hours or more on a RSxx, can you post some quick lumen numbers (new vs. now)?

The JVC lamp hour project thread is not showing any much over 30 hrs, so blasting a query here.

You need a significant drop to see it with eye or to measure it with a cheap meter. The accuracy isn't tight enough, you'll have to wait until some people get to 300+ hours. I have a tiny tiny drop in brightness, but it's not visible by eye yet at 80 hours.

I just checked my RS45 and it has absolutely no vertical streaking. None. Each pixel is a pixel with a distinct line around it. Is your lens dirty ?
post #2167 of 4435
No, the lens was spotless. I don't thnk all 45's have this problem. How did you check for streaking? It shows up the most with bright text on a black background.

I don't think lens is an issue. If it was, then it should be more "localized". The streaking actually happened on any bright text that had a dark background. The Oppo Logo to me is the worst, and then the "power-off warning" screen that Steve Posted earlier. Other that that, if you have a black background, bring up the Menu and all the text there showed streaking, and quite apparent even at 8-10 ft away... I actually had the same thing, and contacting my dealer... but I guess I would have to wait as he is out of stock already. BTW, I have a RS55.

I got it straight on the horizontal plane and just a tad tilted on vertical. I added +1 on keystone at the end of the night and the image is square. I may go back to reset the mount, but it is trial and error as tightening the ball joint isn't very precise. I may fix one axis and have trouble on the other.

Ditto !

What are people using for ceiling mounts on this thing ?
post #2170 of 4435
I don't think the lens hour meter is accurate on my RS45. It says its been running for 8 hours. There is no way its been running for 8 hours. More like 5. Anyone else notice this ?
post #2171 of 4435
Are you running on high? That will clock on more hours.

I would suggest that you try to get a replacement something seems very wrong. I have the 45 and have n streaking on the Oppo Logo or the menu. I don't even see it at one foot from the screen. When you first got your unit where was the lens shift? I am wondering if this problem is only with a small number of units.
post #2173 of 4435
Does anyone know of a good source to calibrate an RS45 with ? Like a DVD or BD of images ?

Is there a HOWTO guide somewhere for setting one up ? I was surprised by how little was in the manual.

BTW: I love my RS45 !

I was not aware of that. I was running on Normal. I am running with a color temp of 8500. Does that make a difference ?

BTW: I'm surprised at how loud the fan is on High.

I thought these things were supposed to be virtually silent. Maybe my mount adapter covers the vent too much. Its a plate that sits about 1/4" above it. I could put a spacer in between.

FWIW, my RS45 mounted to the plate with rubber isolators.

Yeah.. I think I need a replacement. When I first got mine, lens shift is way up.. i.e. it is projected to the ceiling (which makes me worry as I see nothing on my screen ).

Can you tell us your full Signal path ? i.e. Source type , output resolution , cabling , HDMI input , etc. ? I'm wondering if a true "1080p" Text is working and a non-1080p Text is giving the lines .

Yes.. Fan noise on HIGH is pretty loud. I don't think there is anything wrong with your mount, unless you are totally blocking it. On the other hand, LOW lamp is pretty quiet...
post #2178 of 4435
On mine, low lamp is dead silent as in can't hear it from 2 feet away, high lamp is a light whirring sound.

Unlikely.. The projector menu item by itself is also streaking... that means it is NOT source, HDMI, cabling issue.

No need to worry about the lens shift being way up. Mine was the same way as were many others. I don't have the streaking issue. How is your convergence?

If you want to calibrate, you need a calibration disc like DVEHD or AVSHD (Free).
If you want to go further, you need a meter and software as well. There is a "dummies for calibration" guide somewhere out there that describe it.

Convergence is OK... not enough that I need to mess around. And it is pretty sharp as well. It is also pretty bright (700/1100 on THX)... So, the only issue is the streaking..

I finally got my new RS45 ceiling mounted, and I've run into a bit of a problem. It's replacing an RS1, so when I got the new Chief plate, I simply put the RS45 in its place.

But it appears that the range of lens shift is more limited compared to the RS1. After much back and forth with shifting and zooming, I managed to get about 90% of my 106" screen filled, but that's as good as I can get. The throw is short: around 12 feet. The screen is fairly low.

I have an angled bracket attached to my slightly vaulted ceiling with large lag bolts right into a ceiling joist. A 14" or so post comes down from there and then the projector bracket. At the time I wanted to be 100% sure that it was solid, though I probably overdid it.

Anyway, it's around 10-12" left of the center of my screen (how do I figure that out anyway?). So, I'm thinking my only option is to re-install the ceiling mount to be centered with the screen. Would I be OK with toggle bolts into the drywall? I'm not much of a DIY person, so I'm not sure what the best solution is.

As far as I know, centering the image, i.e. moving it parallel to the screen, will not give you any increase in image size. I would verify that before you do the work of moving the mount.

Regarding the lens streaking some are experiencing...
Do any of you with this issue watch foreign movies with subtitles?

How noticable or annoying is it in the above scenario?

Toggle bolt weight capacities are not rated for ceilings, only walls. I definitely would not attempt this with something as heavy as the JVC projector.

you might have to open up that part of the ceiling and run a 2x4 cross brace or something similar to secure it properly.

i havent tried this but see it on some credits (at the beginning of movies, i dont really watch the ones at the end) if i look for it at ~9 ft. I havent watched anything with subtitles, but at that same distance I imagine it would be visible and annoying (again, mainly because I am looking for it - i actually doubt any guest would mention it at 9ft+ if they didnt know to look for it).

Clarify a some setup things:
- your screen size is 106" diagonal or horizontal measurement?
- what is your lens height?
- your 12ft throw distance is for sure from the lens front to the screen?
- a good method to verify lens offset is to get a tape and measure from a common side wall to the lens center, then the same thing for the screen middle. Offset is the diff.

As far as hanging from drywall, don't do it. If you have to hang it from a location without direct access to ceiling joists, then cut a rectangle piece of 3/4" plywood long enough to span the two closest joists and screw that to the ceiling (paint the plywood to match the ceiling or mount). Then attach your mount to the plywood.

But then we're assuming the EEPROM Menu was encoded as a 1080p Text ? I believe the AVSHD709 Disk was all recorded at 1080p . Like to see how a known 1080p Text is displayed . Could be something with the individual setup but best to rule out the obvious . Best if they had an external Pattern Generator.

I can try the AVS disk later today. I see that as Oppo screen, so that should be 1080p as well. I have not try PC yet, had anyone try?
