Official JVC RS15/ HD550 Owner's Thread - Page 2

post #31 of 859
I truly think JVC is going to have a hard time selling the RS 25 (950) against their own 15 (550). Especially after reading more initial thoughts. This may be the PJ to beat in terms of price versus performance making it possibly the best bang for the buck PJ available.

What you are showing isn't convergence. Convergence is how well the red, green and blue panels are aligned. You test for this with a crosshatch pattern. One is found on the free downloadable AVS calibration disk.

What you are showing is that the projector isn't properly aligned with the screen (or vice versa - your wall can be slightly bowed). This can be corrected but it can be a PITA. Try shiming the top right corner of the screen and see what effect that has.

If you look at Jason's measurements, there is quite some overlap in contrast/brightness figures between the 15 and 25 depending on IRIS, lamp setting, zoom,etc. So, max performance will likely be best with the 25 in any given situation, but they are close and I wonder how much difference there is in practical terms.

Of course, you get a full blown CMS with the 25. Hoping to save my money and get an external CMS for my 15 down the road. Perhaps they (CMS) will continue to drop in price and exceed the 25 in CMS features within the life of my 15 - or sooner.

Good points but for the average owner they most likely won't think twice about just getting the 15 (550) and calling it a day...

Are the bottom lines still straight but just go to a lower edge at the right? If so, point the pj ever so slightly to the left and use the lens shift to re-center the image on the screen.

EDIT: You make end up having to adjust the "roll" axis of the pj too. It's just some simple fiddling to get it right.

Thanks for the clarification and suggestions. I thought the same thing and spent the morning working on the projector mount alignment this morning. It's down to about a pixel or 2 now. I can live with that and may add a shim later.

I've never had a PJ with full CMS, so I can't say what that would add. I was debating the 15 vs the 25 and decided to go with the 15 and a new BDP-83. I have no regrets on the decision. I have over 20 hours on the RS-15. Very happy new owner.

Have any of you been former owners of a 9" CRT? I am not really trying to start a debate of digital over analog.. Please avoid it.
Is this as good or better than your 9" CRT?
Is there any motion blurr, that is sometimes evident on certain digitals.
I am very sensitive to motion blurr.

I am using a 9" CRT and got one of the first DILA (g10), which I stopped using years ago. Obviously, Rs15 is probably multiple times superior.

Perhaps its time to move.. to JVC again.. is what I am wondering...
Also, has anyone compared rs15 to rs25? I did read the review thread.. wondering if there is a substantial difference, visible in picture, between the 27,000:1 Vs 50,000:1.
I am not very sensitive to the improvement offered by CMS (so I don't need rs25 for that particular option) - I am the "joe america" who is fine with saturated colors etc..

I purchased the RS15 - this is my first projector. How do you calculate the max allowable mount distance ABOVE the screen for this projector without having to make keystone adjustments? I couldn't find this info in the manual. Thanks in advance.

I guess it's implied with the digaram. My interpretation for a CALCULATION is:

Max mount height above screen = (Screen height *.80 ) - (Screen Height * .50) assuming 0 horizontal shift...it appears 80% is the max vertical shift, this range decreases as horizontal shift is applied.

That seems reasonable. I didn't keep the manual as I'm not an owner. But it's a calculation because they can't cover all specific distances and screen sizes for all positional scenarios otherwise.

I reset the brightness and contrast controls on the Lumagen HDP to their defaults (128), and used Spears and Muncil to tweak both in the RS15. I only needed a few clicks to nail the brightness and contrast. I also found that a significant amount of the black floor on the High Power screen was coming from the display of my Oppo BDP-83, which at least from its most recent firmware upgrade (and possibly longer) has been shining at full brightness, pointed directly at the screen. I quickly engaged its "display off" function, which turns on only upon action and just for a few seconds. The baseline black level is now great, especially considering my high gain screen.

Ok. That's funny. So perhaps you can provide a useful answer to my question? I'm new with projectors myself. I always thought the sock puppet test involved projecting a 100% video black image onto the screen, and then you try to see a hand puppet shadow. The harder it is to see a shadow, the better the black level. If that's correct, my question is what source material do you project to the screen when doing this? Do you use the video black field from a calibration disc? If not, then what do you use?

I just used the "black bars" on a 2.35:1 format BD, but yes, projecting an IRE 0 image, from DVE or another calibration disk, would also work.

I can tell you that on every single pj on this forum on home sized screens you will be able to see a very clear shadow.

The shadow pupet test has no value whatsoever.

Not true, there have been pjs that utilized internal masking which does completely block all projected light (I think the old 720p mitsu 3000 DLPs used it), shadow puppets are also useful without the projector on as you can see how much room light your screen is reflecting.

If I put a lens cap on my pj and stick my habd in front of the lens that tells me a lot about the image quality

I guess shadow puppets also have entertainment value!

Just unboxed and installed the RS15. Replaced DLA-HX2. 96" wide Dazian CCC screen. My HX2 was measuring less than 200 lumens at current lamp life.

No need to compare as the RS15 is obviously superior in all respects (although it is larger).

I will say that low lamp seems to have greater contrast and color depth (to my eye) than high lamp, even at smaller iris.

Best setting for my screen seems to be low lamp, iris open. I wonder if stopping down the iris generally increases diffraction and detracts from other aspects of the image.

I was truly amazed at the ability to render low light detail - even concert fog is clear and detailed! Whole family commented at sharpness and ability to render detail.

Many measurements to make.

I would like to say I have joined the RS15 club as of last Friday, what a step up from the AE900! Settings - out of the box with natural selected and Lens Aperture set to 2 in a 100% light controlled room using a 92" Carada Brilliant White Screen (1.4 Gain). Very happy with my upgrade choice. The only thing that upsets me regarding the unit is that when turning over the projector to set up ceiling mount by removing legs there is a loose screw or nut clanging around inside the unit. JVC / quality control should of caught this. Now I have to take the unit back to JVC and have their engineer open up my unit to find out what is causing the rattling. Loose screw has no effect on project but you never know where the screw / nut lands next time when I actually get around to mounting this monster up on the ceiling.

I head a bit of motion inside as well, but did not seem to be something completely loose and rattling around.
post #51 of 859
Got mine and installed it last night. It looks great (am I silly to say I'm glad I got the gold-edged RS15 instead of the silver edged HD550?), and shipped quickly from the AV Science store.

The image is addictive - put on an animated favorite (Meet the Robinsons) and planned to watch 10 minutes with my son, and wended up watching the whole movie. Great blacks, great color, like the frame interpolation (with animation anyway). 100% happy with my purchase, what an upgrade over the Panasonic PT-AE900 it replaces.

Also, the biggest bonus was how well it fits in my space - I was concerned that most new projector models coming out were too wide for my projector space in the back of the room, but this things fits great.
post #52 of 859
Just as a test I tried the RS15 with a 120" wide sheet (rather than my 96" wide screen).

Plenty of light. (low lamp, wide open iris).

Looks like a screen upgrade is in my future. Zoom method CIH, 122" wide 2.4 aspect.

Congrats Kevin on winning the pj.
I don't want to sound like sour grapes, but I still have to laugh at the original purpose of the contest. It was supposed to be for those people who wore their AVS shirt at Cedia. This was to promote AVS in the industry. Since they changed the contest, I ended up seeing only one person wear a shirt at Cedia. I didn't, as I prefer to wash my shirts before wearing them. For the contest, I would have made an exception.

audvid,
I am not sure what to say. CRTs still win in two areas - on/off cr and motion resolution. I still think 20k to 1 is enough to satisfy even a majority of CRT owners. The JVCs have this covered. I spent a lot of time watching the 35 at Cedia and never did I feel the on/off was lacking. Well, maybe a little. On motion, I didn't really feel an issue with it. It was there, but it didn't bother me. Now, I could see were a one chip dlp could bother you with motion. I could be wrong, but it was more apparent with dlp. I am guessing you aren't in the three chip dlp buying camp, but those just don't seem to have the same problem with motion. Except for the lack of on/off cr, the three chip dlp would be my choice. Unfortunately, this is going to be a personal decision and you will probably have to see it for yourself. I don't believe I have seen any ex-CRTers complain about motion on their JVCs. How is that? Do I win your CRT pj?

That's a wall mounted JVC 65S998 behind the boxes in the second of the attached pictures; it's a great three chip LCoS RP set, and very thin due to a folded optical path, but was only on the market for a few months before JVC exited the RP space. We use it for daytime and casual TV use, reserving the front projector for films and other content worth seeing on the big screen (although 100" is at the low end of screen sizes on this forum). The motorized screen drops just in front of the RP set.

It was a little sad to unplug the RS1 after two and a half years of excellent service. The RS15 is narrower, and fit handily on top of the Oppo BDP-83 that I picked up during their Early Adopters program. I found a $3.50 right-angle HDMI adapter at Monoprice (third image) that prevented the HDMI cable from sticking out towards the couch.

The power lens cover is very cool. I had just finished carefully cleaning the RS1's dusty lens a few days ago, using a Zeiss pre-moistened lens cloth.

As soon as the RS15 turned on, I noticed was that the initial image was thrown way high and to the right; I had assumed that the default position would be much closer to the axis. I was quickly able to zoom out a bunch and center the image (I project from near the far end of the range for my 100" screen, which drops lumens, but increases contrast). The power lens shift, zoom, and focus are really nice; I no longer need binoculars to focus! The resolution is fine enough for centering, and the backlash is noticeable but modest.

One thing that I don't understand is that when I center the green grid of squares on the screen, and drop in a Blu-Ray Disc, the movie's image is offset about two inches to the right. Weird.

On reading the manual, I noticed that even though the bulb is the same as that used in the RS10 and RS20 (BHL5010-S), the quoted lifetime has increased 50% from 2000 to 3000 hours! That's good news, but I wonder if the RS15 operates the lamp at slightly lower current, or if JVC has simply amassed enough life test data to raise the number, and RS10/20 users will also experience 3000 hour bulb life.

The image is definitely brighter, although this is probably partly the new bulb and the increase in lumens from the RS1 to the RS15. I can still see hand puppets, but that was expected - even with the gains in contrast ratio, we still have a ways to go until the black bars are truly black, especially given my high Power screen fabric.

I did spot one central and two fainter slightly brighter than background vertical bands in a dark scene in Changling. I had that once before on the RS1, and forget what led to it and how I made it go away. A quick switch to The Fifth Element showed that it was not the projector. Some HDMI quirk?

I have a Lumagen HDP to address the oversaturated primaries. It's not a RadienceXD, and the secondaries are not quite where they belong, but it does the job.

I'll need a few hours before I could make any critical observations, let alone run HCFR, and with a wedding in my wife's family this weekend, time will be hard to come by.

Kevin

Congrats Kevin! Glad to see you won! Any questions don't hesitate to ask me.

Went to JVC today and had their engineer take apart my RS15. He found a floater! an extra loose screw which was probably lost on the assembly line.

Oh, so that's where it went!

Not sure where you are located but it sounds like a very convenient spot for walk in same day service like that. Nice.
post #58 of 859
I am about 30 minutes away from their Toronto service department. While I was waiting I watched a video on the clear motion drive 2 technology very interesting! It helped pass the time. Location of service center was another reason why I chose JVC this time around

I am currently waiting to see if I could grab a JVC RS20 on a close out. Maybe I am better off buying the RS15 instead? Anyone has seen both?
