JVC New Projectors Announced - CEDIA 2012 - Page 9

I'm not sure about the comparisons to the other projectors, however one advantage of a larger screen is that the black levels will appear blacker because the light leakage is spread over a wider screen area so won't raise the black levels as much (note the contrast performance is unchanged as whites won't get as bright).

Zombie's approach with a high gain is the best for a large bright screen with good contrast - if you can stand the extra shimmer/glistening of a highly reflective screen (I can't).

How silent are the fans of the current JVC projectors, and would we expect the newer ones to be similar? My old projector is installed almost above the seating area and I would like to update my old projector. One of my criteria is to have a silent projector. One thing that I really like about the Sony projectors are that you really can't hear their fans even up close (especially in low lamp mode). I looked at JVC projectors recently but I've only demoed them in places with a lot of background noise from the stores, so I really can't tell how loud their fans really are.

Thanks.

That shimmer/glistening artifact is a common problem with high gain angular reflective screens. The retro-reflective High Power material doesn't suffer from that problem.

A larger screen drops black level and white level by the same amount so definitely not.

I think a slogan I am picking up here is "An angular reflective screen with a gain higher than 1.0 is not a screen, its a concave mirror regardless whether its curved or not." Of course, I could come up with a negative slogan about the HP2.4 too but I am too modest, way too modest, to show off here and I am scared for my safety given the number of HP fanatics on the AV Science forum.

I want to ask a question I already have the answer to, and maybe the only person the have seen it... But...

Does anyone know the limitations of e-shift and the 120thz panel?

(Alot of people are saying they have a good eye, and I'm going to test this theory) wink.gif
post #248 of 1073
Ok, no one wants to answer... Lol.

Get close to your screen with a current e-shift projector and move something white across a darker background via PC or game console. If you move the object fast enough e-shift no longer works on the object you are moving. So even in movies that have things on screen moving fast enough the e-shift will not work on specific parts of the screen. AKA: You can see pixel structure on moving objects, once things slow down enough the e-shift is back on full force. smile.gif


*And because I'm so great at spotting things, I should be the first one to receive the new JVC... cool.gifbiggrin.gif

I have not seen what you are talking about with the HP 2.8. I do notice other screen texture characteristics, but shimmering/glistening is not part of the list.

As henrich3 stated, you don't see that with a HP screen.

Given dimming rates of current lamps, JVC'd claims could be put to the test by observing how much dimming the new ones have in the first several hundred hours, especially at high lamp power given JVC's caveats about that.

I don't follow.

As angular reflective screen gain increases, it more closely approaches a flat mirror.

Trying not to turn this thread into a HP discussion (Zombie started it :-)) but if the HP is more like a mirror won't it hotspot? I guess I have to see one for myself, but I do like the neutrality of my Studiotek 1.3 screen.

Also, regarding e-shift and movement, the eye is less sensitive to details in movement and at 24Hz things are pretty blurry anyway. Mark mentions that the e-shift processing is much improved for 2013 models so I wonder if the new JVC e-shift will process more movement?

I don't think they can fix what I'm talking about with a 120htz panel. They need to go to 240 or greater to fix.

"hz" must be expensive! biggrin.gif the way they avoid going to 240. curious why they haven't like you are getting at.....what could possibly be the downside?

They would also need the e-shift panel to run at 240htz. More money then they want to spend in r&d right now.

The HP material is amazing. I can confirm that it does NOT sparkle, even in white scenes. If you image the surface at really high magnification, it looks like little half-spheres protruding out of the surface. So I don't know why it doesn't sparkle, but it just doesn't.

You can call up Da-Lite or Draper & get samples for free.

I would guess that Contrast ratio is the tradeoff.

It's not like a mirror but like a road sign reflecting your headlights back towards the car. It won't hotspot. The drawbacks are limited placement possibilities of projector and viewers to obtain the gain (i.e. the viewers have to sit relatively close to the projector).

I'm kinda surprised about the very little interest in my finding on E-Shift. Anyone at least try it to replicate?
post #261 of 1073
I don't think this test is applicable to a singular frame displayed in two flashes to make up the full frame.

What you are replicating here seems to be analogous to an interlaced action capture in reverse....won't affect film viewing, gaming may be a different story.
post #262 of 1073
SOWK, that's interesting. And given how I spot all sorts of imperfections in tech, I'm pretty sure I'd see it as well. 6x DLP color wheels aren't good enough for me; heck, even the effective >30x color cycling LED Runco (I think?) DLP projector had weird artifacting to my eyes... looked like the image was repeatedly flashed in front of my eyes when I moved my eyes around.

I bet you you could show it with a high speed camera.

Just out of curiosity I became interested in trying to capture motion blur & quantitate using high shutter speed capture. Turned into quite a headache to actually try to quantitate it, but I think I was able to come up with a method of at least comparing projectors.

Would love to put a JVC through that test, due to its purported motion blur issues. I wonder if the chips just have a thicker layer of liquid crystals on them to give the deeper blacks... that in turn might slow down the response time. But that's totally just a guess/shot in the dark that may have no basis in reality smile.gif

Sowk, I think you are confusing image processing speed with native refresh rates.

Well, since it looks like you are getting another JVC, I'm guessing you never saw any issues during normal viewing. wink.gif
post #266 of 1073
Everthing has issues. No matter what one picks, if you are a trained issue spotter, you will find them. Everything depends on your sensitivity to a particular issue.If you are able to observe an issue, then you musy decide, does X projector have the net positive sum gain without a game disqualifier issue. I own a great projector, the Sony VPL-vw1000ES. It has issues but to me the positives outweigh the issues substantially and the issues I see are not deal breakers. The positive sum justifies to me, the price, which fortunatel I can afford.

I could say the same thing about this year's JVCs. I could enjoy one immensely. No deal breakers or game disqualifications for me. And assuming the same proprtionate street price discounts over MSRP a very fine value.

Are there better projectors out there at much higher prices. I won't answer that. smile.gif But even a higher price machine migh have an issue that would be a deal breaker even though the net positive sum might be greater. Then one must decide assuming available funding does the greater positive sum justify the additional cost. Everyone's decision could vary here We live in an era of good affordable machines at various price affordability points.

Written like a lawyer turned salesman. smile.gif

The JVC´s ( I tested the X70/RS55 ) in low lamp mode, is like the Sony´s in high mode ( here I compared with the 95ES )

Thanks. That's the impression when I compared Sony and JVC 3 or so years ago and was wondering if that was still the case. That makes the decision for me a little tougher since a silent fan is a critical feature for me (as well as a great 2D feature - 3D important but not as critical as silent fan and good. 3D. I also like that JVC has TCP).

Well from what I've mostly heard about the recent JVCs, the fan on low lamp mode is "essentially silent" or close to silent. Really, on low lamp there should be no problem with fan noise. Of course, when you put it on high mode its more audible but still not intrusive as to ruin the movie experience. The Sonys are definitely excellent with the fan noise as well. Bottom line, the JVCs on low lamp shouldn't be a problem unless the projector is like an inch from your ear. smile.gif

I usually never hear mine which about 2' above my head.
