Official JVC RS40/X3 Owners Thread - Page 204

I am considering to put RS40 onto the wall instead of hanging over the ceiling for the following reasons.

1. I am buying Dalite HP 2.4 screen. I read that retroreflective screens should be placed just above ears at the center of the screen.
2. I don't have power connector at the ceiling.


Do you agree with me? I don't know what to search on. I am assuming that I need to place some plate on to the wall and put projector on top of it. Is anybody using this kind of mount?

It should like some thing like this


Appreciate any link on where can I buy it.

That's the correct geometry to get the best performance from the HP screens. The AVS Store (link is HERE for phone numbers), that operates this forum, sells Da-lite screens. Just give Mark or David a call for options and pricing.

That's the setup I have. Projector about 9"-12" above and 12"-15" behind my head. Screen center is slightly above eyes. My throw is about 15' to 106" 16x9 screen. Works great. HP is everything users rave about. In my opinion, over 90% of users on this chat can't see the so-called irregularities of the HP.

I have CI on D*. Hockey is great. Don't even have to use the CMD function. Gradients of white ice on the RS40 are very good. Better than my calibrated Sharp 12000MKII in the other video room.

I am glad to read that. Tx

I have a setup similar to this, but use a stand (the PHT-800-1250 from Dalite) that is located just behind the recliners; height can be adjusted from 31" to 49", just right to have the pj project over your heads. And this is even BETTER for the HP screen.

I also have a similar setup, but my PJ...an RS1 (soon to be an RS40) is mounted on a shelf in a closet that can be closed when the PJ is not in use.

My HP 2.8 screen is 106" diagonal and the throw is 15'. The RS1 looks fantastic on this...I am excited to see what the RS40 can do.

Ohh big hockey fan here. Looks awesome but the mini 3D is taking it to the next level. Since they don't give those mini's away, I suggest you try it without. Then, if you think it can be improved order a mini from a company that provides a good return policy in case you don't think it does it for you.

Good luck.

I own the 50, and am a big hockey fan - I won't go very much in depth here since I posted a lot of detail in a separate JVC/Sony comparison thread...

Essentially, I find the the 50's motion handling improved over the HD750 which I owned a few years back, but Sony's prior VPL-VW85, which I also own, is outstanding on sports, especially hockey. The ability to use both their motion enhancer technologies together (if you have the screen gain), lends the unit to incredibly smooth motion.

I owned this years Sony as well, the VPL-VW90, but returned it (for other reasons). It was not as good as the 85 in terms of motion handling, but still a bit better for sports than the RS-50.

The JVC's blur more compared to the Sony's - when I watch the 50 and 85 in an a/b comparison, I see more detail in player's jersey's, board graphics, etc on the Sony during panning. The problem with the 90 is that they changed some of the motion handling options, and I noticed red-green edge fringing with their Film Mode active, which does not occur with the 85. This fringing is also evident on the JVC when activating CMD modes one or two, and I wish they would fix this.

So if you're a big hockey fan, look at this carefully. Another option would be something like the Epson's, which are great for motion handling, but not as good for films and have their quality control issues//

My 126"diag HP2.8 is near min throw to my RS20, lens a bit less than 13 ft from the screen.

Of course all this depends on one's individual room and the limitations for the arrangements. I'm rather fortunate to be able to have things completely optimal for an HP (but I planned things to use the HP from the beginning of my transition to front projection).

I never knew this stand before. I will research on it. Is it sturdy enough to keep projector safe from kids? Curious to know what is the height you set it now?

Did you evaluate any other stands or support that can be attached to wall?

Is anybody here using Da-Lite Cinema Vision, I’m planning to have 114” diagonal with throwing distance of 3.5m. I don’t know how the fabric is & if it have hotspot or other issues. So your feedback is highly appreciated. I’m going to have the project ceiling mount.

I have High Contrast Cinema Vision, that is the gray one.
Ceiling mount works great with it, As there is almost no light dropoff with angle.
The Screen has sparcles and there is a hotspot, but you cant notice any of it during normal movie viewing. I do sit at a great distance from the screen, so maybe at THX recommended distances you would notice the sparcles.
I cant comment on the white Cinema Vision tho.
The worst part with the HCCV is the Smell, i have it for 2 weeks now, i vent the room every day, but it still bites in my nose. However, my GF doesn't notice it.

This is how I do mine:

I received my RS-40 yesterday and hung it from the ceiling last night. I was upgrading from a circa 2004 JVC HX-1. It boasted a "High Contrast Ratio" of 800:1, 1000 lumens, 720P "highest native resolution in its class", and a MSRP about 3 times the RS-40.

Needless to say, WOW. All of the great things about this projector have been stated over and over but there were a few things about it that surprised me. For one thing, this PJ is quiet. I had to put my ear next to it to tell if the fan was on during normal lamp mode. During high lamp mode, I could hear it but it was still MUCH quieter than my HX-1.
Bright! I was very concerned about this. My HX-1 was also rated at 1000 lumens and was fairly dim on my 110" diagonal Screen Research Clearpix 2 screen. It seems that most people here are using much higher gain screens so I was concerned whether or not it would be bright enough. It delivers. At the very least, it gives me some breathing room for the lamp to age while I wait for higher gain AT screens hit the market. I am very happy with this image in 2D as well as 3D. I threw in Tangled 3d just to check how it looked and was immediately immersed in the image. No artifacts whatsoever. I did find the JVC glasses a bit uncomfortable but I noticed they come with a few optional nose pieces so I will experiment with them.
I was having some HDMI issues (I think they were more related to my particular setup rather than the PJ itself) last night so I didn't get to play too much but I am so looking forward to watching some movies now.
I completely understand the enthusiasm now over this projector. I knew it would look good but it is way better than I imagined. The only improvement in a projector I would like at this point would be a stable light source because I know the lamp will dim with age. The RS-40 will be a great addition until bright LED's or lasers are available.

I did a lot of stand research when getting my RS1 several yrs ago and settled on the PH 800-1250 as the best for me (not the PHT version, since I didn't need the tilt feature). It's available from many places online (Amazon, BH, etc.). It's the perfect size for the JVC's, and the perfect height for the HP screen. I have it just a ft or so behind our heads and at a ht so that the lens is a ft or less above eye level (easy to experiment and find the optimum to keep it low, but not too low). In my room it's about 3-4 ft from the back wall, and I didn't want the pj that far back.

To make it extra stable I use 4 15lb barbells (that I don't use anymore as intended!) that are laid across the bottom metal bar, and also two bungie cords over the top of the pj, hooked to the metal frame around the stand's top surface. As you can tell, mine is not a custom designed HT, but a former master BR that I've taken over and added black material over the side walls and ceiling, black out drapes over the external windows, etc., but it's homey, definitely not 'hollywoodized'.

thank you for your input even the screen seller is telling me that the Cinema Vision has a bit hot-spotting and he recommend Da-Matt instead, and I'm confused again

I don't know about hot-spotting but I wouldn't use a gray screen anyway. Its advantages were dubious with older projectors (I never bought into its advantages) and with modern high-contrast projectors, they are just a waste of brightness. Too bright? Blacks not black enough? Just clamp down the iris to tame those blacks and get a TRUE contrast ratio improvement from the smaller iris to boot. Gray screens just throw performance away for nothing.

For 3D viewing you would be much better served with the white Cinema Vision fabric rather than the unity gain Da-Matte. The Cinema Vision retains a lot of the light polarization coming from the JVC projectors and as a result you will need to use the JVC 3D glasses (and not the Xpand or Monster universal 3D glass which have the opposite polarization of the JVC projectors). This characteristic of the Cinema Vision will give you an additional gain boost for 3D viewing which is a big plus since 3D mode is much dimmer than 2D mode and the brightness to your eyes will be approx. twice as much with the Cinema Vision as compared to the Da Matte when viewing 3D using the JVC Projector and JVC 3D glasses. I do admit that for pure 2D viewing the Da-Matte will provide a little better image (but also just a little dimmer) but it would still be plenty bright of 2D viewing if your room has full control of lighting. I suggest you check out the Screens for 3D Projection thread in the 3D area of the AVS forum.

If you can mount the projector near eye-level (e.g., within 2 feet, or 60 cm, of eye level when seated) then the Da-lite High Power fabic (gain = 2.4) becomes a real attractive alternative for use with the JVC projectors.

Hi

Thanks for that, I'm really a big hockey fan..go habs go and I surely do not want to be disappointed with my next projector since I don't intend to upgrade for a few years after. I guess coming from a sharp dt-400, I can't go wrong here, but would you think that having the cable signal go through a lumagen mini would improved how the projector render the fast panning motion?

many thanks Ron, I guess then I'll proceed with the Cinema vision. Unfortunately, my seating will be against the back wall which make the HP screen a difficult choice (watching movies with a giant device above closely above your head )
I red your thread several time very informative specially the screen comparisons in page 3

Has anyone compared the RS40 to the RS50 in the terms of black level? I am less concerned with the CMS as I will have the unitl calibrated, but am very concerned with having the best black level coming from a Sony G90 CRT. My potential screen is a 1.4 or 2.0 gain 138 inch diag/2:35 screen with masking to 120 inch diag/16x9 screen.

Would I see a black level diff between the two units?

Don't be too quick to dismiss the CMS just because you are having it calibrated. There are corrections even a professional calibrator can't perform if the tools aren't present on the projector and a CMS is an important tool.

After the long wait I've decided to skip this generation of 3D projectors from JVC, and here are my reasons:

1. Many reports of lamp and possible power supply issues, along with lens shift problems. And don't tell me only complainers post to this forum. Many complaints were appearing when the actual number of units in the wild were very, very low. People are still having problems with their units. Also, dealers have reported the same thing, relative to previous years.

2. CEDIA is not very far off now. Maybe by then JVC will have worked out the kinks in the current generation and an "RS45" will be just the ticket. Or another company may announce a decent DLP solution (no worries about misconvergence). Or something completely unexpected will be announced. Who knows but, after waiting all this time for a projector, it finally doesn't bother me much to wait a little longer to see what's in the pipeline. Sure, if it's JVC that means delivery in early 2012 but I'm willing to wait if I feel it's not the crap shoot this generation seems to be.

I have a pair of Philips PTA03 3D glasses that are compatible with the JVCs, and I'm willing to part with them for their cost to me. They're new, unopened. Send me a PM if interested.

will the jvc glasses work on the HP 2.4 Dalite?

Yes, but I think Ron Jones has said that since the HP doesnt retain any polarization, the Xpands [which are a cheaper price] would give identical results, all but from the tint differences.

I went with the JVC's even though I have an HP 2.4 dalite, but I really like the automatic on/off feature the JVCs have [but the xpands do not offer]. I however, cannot use these just yet as im still waiting for my RS40. But AVScience is great so I have no worries.

We watch all kinds of 1080i DirecTV broadcast hockey and it looks great with a naked RS40.

At the same throw distance for both projectors (i.e., both with the same zoom settings) and if you use the iris and lamp mode to get identical reference white level from both projectors (for example, to get 16 ftL from your given screen in 2D mode) and also calibrate for the correct reference black level, then I suspect (but have not myself attempted to measure) that both the RS40 and RS50 will produce similar black levels. This is different than saying what its the max. CR you can achieve with these projectors (as JVC does in their spec. sheets), since the RS50 should be better, but in order to get that better CR is must be operated in a mode that is providing lower lumens output. So if you are going to do an apples-to-apples comparison set up both projectors to provide the specific image brightness for reference white you want to have in your home theater (e.g, 16 ftL), then measure the level for reference black.

As for CMS, if you are not satified with the RS40's color accuracy you still have the option of later adding the 3Dmini processor that has better CMS capabilities then the RS50/60 and even the RS40 + 3Dmini combo will cost less than a RS50.

The lumen disparity between the 40 & 50 doesn't help the 50's cause either because setting both of them to the same WL means the 40 would be stopped down more than the 50. I wouldn't want to bet on which one wins.....



But if I did I'd bet the 40 to win.....

I am moving up from an RS1 and I just got the rs40 installed. I plan to post some comparisons with my totally unscientific tests (not sure if anyone cares about comparisons with the RS1 anymore). FYI I have a 106" HP 2.8 screen at 15ft with the PJ at shoulder level when standing. Everything is at default settings. I am waiting on a couple of Xpands I picked up for $99 each so my observations are for 2D only for now.

Random impresssions:

1. Blacks...WOW. A vast improvement over the RS1 (not so suprising I suppose)...and thats comparing a new bulb to a 1000 hour bulb on the RS1. My 'finger puppet' test for a 0 IRE pattern had detectable puppets...but barely to my eye. I can't imagine anyone complaining that the blacks are not good enough on this PJ.

2. Brightness is excellent. Normal lamp and -15 iris is quite bright on my HP screen. 3D mode is too bright even with my nvidia glasses on. High lamp in any mode is too bright for my light controlled room unless I put the lights up....but thats good news as the bulb ages. My RS1 is on high lamp and 1000h on the bulb...still quite a bit shy of the RS40 with normal lamp and -15 iris.

3. uniformity is much better than the RS1.

4. the normal lamp mode is virtually silent. High lamp is about as loud as my RS1 in normal mode...which is audible but not distracting.


I havn't seen 3D at home yet (tommorrow I hope), but I did watch a 30 minute demo in the store on a high contrast gray screen at default settings with no warm up....some scenes were simply stunning. 99% of the time I saw no ghosting at all. I did see some flicker from the avatar clip but that was when the PJ was started up cold early in the demo. I saw no flicker in the final 5-10 mins. The image was as bright (to my eye) through the glasses on the ~130 low gain screen as it was on the panny 50" plasma in 3d mode through the glasses. I am 99% certain the PJ was not in the 3d 8500k setting unless the PJ switches automatically when displaying 3d content. It looked and sounded like the lamp stayed in normal mode when it cycled to 3d material.

I was so impressed I walked out of the store with a box in my arms.

More impressions later.
