I am betting this is 100% setup related. This has been identical on BOTH my 40 and 45. I also saw the same thing on Sams 40, but not quite as noticeable which could be due to his lower gain screen, ceiling mount, or other setup variable.

My experience is that's it's not related to setup. The first RS45 I received had really bad vertical streaking which could easily be see from my seating position. It was sent back defective. The second one has very little with the exact same setup and is a huge improvement.

I agree, send it back, guys don't wait so long to question an issue. There is no way as picky as I am that I wouldn't notice the difference between the RS-45 sharpness and my DLP. I have returned 5+ projectors due to lack of sharpness, and one thing the RS-45 has is sharpness, period.

You should be testing your projector first and using it later.

Well, I have two adjustable rear shelves that I use for my theater room. They are installed on a wall bracket 16.7 ft from my screen. My HD250 was on the top shelf which is lined up to the top of screen. So with the length being around 24 inches, my throw was 14.7. I also have a Benq 6000 on the other shelf which is lined up center of screen; about a 15.7 throw on it. I have no issues with streaking on them. I have the painted black walls and ceiling and total light control in this room. I was thinking that the lens shift could be what is wrong with the RS45. When I initially installed it on the shelf that the HD250 is on, I noticed the streaking. I then installed on middle shelf which is dead center and from what I read on here, the preferred spot. It still has the streaking on it. I've already emailed AVS to see what direction I need to go in. I do want this to work because I really want to go back to a one projector setup but I'm not going to keep a projector that the picture is worse than the Benq 6000 and HD 250. I actually watched a few scenes from Planet of the Apes last night on all three projectors and the RS45 was the worst.

Let me try to understand.. so, you will still have streaking even if you have a good unit, right? I think mine is OK, but the Oppo home screen still had quite some streaking (on the p). Is this "normal"?

Wow that does look bad! Mine has very slight streaks coming off some of the white lettering. It's not a big deal here as I would need to get my nose close to the screen to see it. I would definitely send that one back!

Thanks Steve. I stand corrected. That picture in your post is very extreme and considerably worse than the 2 40s and 45 I have seen.

All 3 units I have seen showed what you are talking about on the Oppo home screen.

When I received the projector and power it on for the first time, it had extreme vertical shift applied to it. The picture was on my ceiling. Just wondering if there is any correlation between that and the streaky lines.

Nah, same with most people, although mine was only at 50% lens shift oddly enough. Almost everyone elses was on the ceiling.

There is no way I can move the emitter closer to the screen and have the signal pass over the back row seating at the same time.. unless I'm missing not getting what you are trying to say.

I don't understand this at all. The emitter is supposed to go on top of the projector and point towards the screen. PJ is 17' away so the cord wouldn't be long enough anyways even if this was a solution.

You are trying to shoot the signal 33 feet if I remember correctly and bouncing it off the screen to boot. That is a long way for IR to travel. Are you sure that you have the angle correct on the sensor so that when the signal hits the front screen and bounces off, it is not getting blocked by the front seats?

Did you see this in the first few hours of using it?

I just don't see it. Played COD last night and didn't affect me. Maybe I'm just not susceptible to it.

Don't think the front seats would be blocking the signal as the back seats are on a riser. If I hold the emitter like say beside my ear towards the screen it works perfectly fine. So the distance seems fine.

Maybe I should mount the emitter on the ceiling just off to the side of the PJ and a little bit back. I don't know what else to try. I have adjusted the emitter's angle repeatedly. Maybe it's because the RPAU mount and PJ are so close to the ceiling that it's having an affect on it? But I don't think so because front row is fine.

That tells me that the problem is not the emitter. It is the location and/or angle that is causing the problem. I would rig some thing up so that the emitter can be mounted under the projector.

My emitter blocks the signal of my Samsung Bluray player remote, guess it's a conflict, it only blocks it while in 3D mode, of course when in 3D mode is the only time the emitter should be active.

The Samsung remote can still over-power the emitter if I am close enough to the device, but it is a tad bit of a distraction, nothing major however.

Ok. I think i will try some velcro on it and place it on the bottom of the RS45 then or perhaps the side. I'll report back

Other than CRT no.

Another repeat, but the cheap DLP option as a secondary projector is the only way to get no blur on rendered game textures during fast movement, irregardless of lag response which only FPS gamers will care about. You can't get a projector to do everything right, not yet.

The low lag doesn't help the blur these projectors sometimes get due to slower pixel response speeds, and I see this on both LCD and LCOS, but not on DLP. The blur is not an issue for movies or most video content, but it is in gaming. When I see someone asking about lag on an LCOS, if they are that sensitive to LAG (which IMHO is not nearly as big of a deal as blur in gaming), then I can't imagine they won't be sensitive to the blur even more so, but I suppose anything is possible.

The JVC is fine for gaming, but I am just saying if people are so worried about lag, there are other issues as well and they mise well just go to a DLP for the gaming.

Hi,

I own a JVC X30 (RS 45). It's still sleeping on the floor as i'm not living at home now (can't wait to...). I still hesitate about what kind of DIY screen i should built : 2.35 or 1.77 ?

3D is for my 6 years old daughter... She will only watch anime like Disney, Pixar... So a lot of contents in 1.77 size. Some movies for children like "Karate Kid 2010" (she likes it very much ).
If i choose 1.77 screen size, it will be about 2,1 meters width.

2D is for me. I watch a lot of movies (so 2.35 most of the time) and some of your best series (Dexter, The walking dead, Vampire's diaries, and so...). I still don't know if i will play games (PS3, X360, PC) with the JVC (because of its lag).
2.35 should be fine for me and the screen size would be 2,4 meters width (bigger than the 1.77 one because if i build a 1.77 screen with 2,4 meters width, it will be too big for my wall (because of the eight of the screen).

If i choose the cinemascope size of screen, here comes the problem.
I've seen the lens memory of the JVC X30 working to my dealer's shop. It seemed to be great. But i've heard that some people had problem with the memory lens. It wasn't coming back to the right place after zooming for 2.35 contents...

So i have 2 simples questions :

- 1.77 or 2.35 ?
- those who use the lens memory, does it work fine ? Do you think it's a good idea to use it each time i want to watch a 2.35 movie (i ask because JVC seemed to have problems in a near past with the quality of its units (especially bulbs) ?

By the way, i don't know if this is important or not but i will use an HTPC to feed my JVC. So if i choose a 2.35 width screen, each time the movie will ended, i'll have to use the lens memory to go back to 1.77 width for Windows...

Thanks.

Vincent

I tested the white streaks, the streaks are mostly invisible on my unit, it's hard to see them even with my nose to the screen, it takes white on black more than anything to really see them. Moving back 1 foot or so from the screen and they are completely gone. So I would say if someone can see the streaks even from 1/2 seating distance, that is maybe too much.

@CIH - Lens Memory
It works good enough, you may have to make a very slight correction with the remote afterward, but it is much better than doing it manually, and how often are you really going to go back and forth, I mean it's not something most people do constantly, just at the beginning of viewing and end usually.

I'd go 2.35 if you watch more movies, but also keep in mind that the black bars on the JVC are so dark that even if you do not go 2.35, the black bars really are not very visible at all compared to most projectors. You can still see them a tiny bit, but hardly, it almost looks like masking without masking.

If you run out of height before width, a 2.35 screen would be the way to go especially considering your viewing habbits. It sounds like your 1.78 image will be the same size either way, but with a 2.35 screen you will get a much larger and more dramatic scope image which is the way it is meant to be seen.

The other great thing about a 2.35 screen is the side bars are much less noticeable I find since they are not projected light like you get with the top/bottom bars on a 1.78 screen. Masking was always in the back of my mind with my 1.78 screen, but I have never felt the need with the side bars on the 2.35 screen as they simply do not draw attention.

As far as lens memory, more times than not, I have to tweak the lens shift slightly with my particular 45 since it rarely is dead on. It is not that far off, but I still find I need to tweak it slightly in either the vertical, horizontal or both. I dont find this to be a big deal at all, but the memory function (on my 45 at least) is definitely not perfect.

Prostic, if you are thinking of building a DIY 2.35 screen then once you have it setup and are happy with where you have your lens then you can simply zoom/focus to get a 16X9 setup on the screen and set lens memory.

Best of both worlds!

Coderguy, is your viewing area a batcave-type room, with dark walls, ceiling, etc.? I keep wondering if the better black levels of the RS45 wouldn't matter in a non-batcave room.

It is, but I am not watching the JVC in the same room I set it up in, because I am re-doing the room and had to move stuff out of the way. I thought the room was good to go but it has cooling issues. Right now I have 2 white walls and a partly white ceiling in this temporary room I'm using, but they are pretty far apart. The blacks don't look as good as the other room, but they still look pretty good and the contrast still helps.

My main problem is cooling, I have an AC guy coming to look at it in a couple days and try to make it so that I don't have to close the vents around the house to keep this one room cool. I have another projector in this same room and 2 PC's and this room was always a little warmer than the others, so it's a triple issue.
