It appears I will have to retract that statement. Perhaps the month of exclusive ZT60 viewing "dulled" my senses.

A "split-screen" comparison test Between the Carada BW 1.4 and the Reference 4K 100 revealed little difference in brightness or color accuracy.
The Carada is slightly "warmer", but the Reference 4K 1.0 certainly holds it's own against the Caradas's 1.4 gain.

The Reference 4K is the upper half of each photo, the Carada is the lower portion.
There is no photoshop or any other editing other than to reduce size. The Carada screen was simply placed in front of the Reference 4K.
Camera was a Nexus 5, handheld, from the viewing position at 13'. (a bit of a lazy test setup, but color accuracy was not the goal, just a subjective comparison.)

I'll proceed to re-calibrate against the Reference 4K with a fresh lamp and then provide some actual measurements.

I was surprised by the amount of light passing through the screen...this material seems suited for rear projection, as well as front projection.
Very curious as the Elunevision web page for this screen material says: "opaque material to block light from opposite side"

Opacity can be a critical factor in some installations. It could be a big problem for some buyers if their page was inaccurate on this count.

Any elaboration appreciated.

I have a 60" plasma tv 2' behind my 106" Elunevision Reference 4K screen and with the tv on in a darkened room I can not see any light coming through at all. My screen is not the audio transparent one.

Well.. I suppose "opaque" is a subjective term.
I was not surprised that light passed through the screen, just expected less.

I have a couple of sconces, from the Uptown Theatre prior to it burning in 1960, on either side of the screen that served as accent lighting. They must now be left completely off.
Fortunately my stage area is all red oak with 3 applications of Cabernet stain, making it very dark behind the screen and to the sides.

My screen comes down about 6 inches in front of the plasma.
The ZT60 has much lower reflectivity than past plasmas, due to some new screen bonding process.

So far, I have not noticed any reflections off the plasma back to the screen during normal viewing.

My only concern is that I have not been able to set the gamma higher than 2.0 on the first couple attempts. (the gamma controls are not very good on the PT-AE2000u, so I'll have to work at the hard way....they were greatly improved on later models).
A blanket over the plasma will quickly confirm if there is an issue with reflections washing out the picture enough to effect the gamma measurement.

Looking at the photos, you might be thinking OMG!, but the setup is biased to record the light through the screen, and the ZT60 is set to 30fL.

The first photo is looking behind the screen from the side...Ref4K on the right side, plasma panel on the left.
The second photo is taken from the seating position, with 75% Color bars on the plasma behind the screen, which has 0% White projected on it.
Third photo has 100% Green Full field pattern on the plasma.

Wow, that is a lot of light shining through. When my Samsung 60" plasma is on there is no visible light bleeding through from the back. In looking at the back of the screen while watching a movie, I can see the image from the projector through the back but it is quite dim. Reflected light from the plasma screen 2' away would probably not be noticeable.

I tried putting a bright flash light (one of those 3 LED types that you can hardly look into) a few inches behind the screen and I did see it shining through. The screen isn't completely opaque but under normal viewing conditions I don't think there is a problem imho.

While opaque may have more than one definition, this is the first from dictionary.com

"adjective
1.
not transparent or translucent; impenetrable to light; not allowing light to pass through."


Your photos certainly show a large amount of light passing through a screen which is advertised as "opaque material to block light from the other side"

If one was using a drop down screen in front of a window, or a mirror, this would be a deal killer. Based on the advertising, the buyer would certainly assume otherwise.

EluneVision screens

Does anyone know if there are any distributors that have a demo of the Elunevision 4K Reference electric tension in Southern California? I would love to see this screen.
