SI Black Diamond screen instead of a 4-way masking solution?

Hi,

I’m considering a 2:1 screen (140” wide X 70” high), to allow me to project both 2.35:1 and 16:9 content, without a 4-way masking solution, and without compromising on the respective screen size for the dual-formats.

The 2.35:1 content will display on a 140” X 59” image within that large Black Diamond screen.
And the 16:9 content will display on a 125” X 70” image within that larger screen.

And no masking system would be required (I'm theorizing here) – because the edge of the Black Diamond screen is, well, black.

Has anyone tried this? Can you say whether the black nature of the Black Diamond screen indeed means no separate masking system would be required?
And that’s assuming Black Diamond will custom make a 2:1 screen at this size (I sent them an email, no reply yet).

Thanks,
Shahar

In a good room with darker content, you would not see the screen, if you have a high native contrast projector like a JVC. With brighter content, you will be able to see the screen. Especially when projecting scope content zoomed, because you will be projecting a 16:9 image and the black bars will be brighter than the unlit portions of the screen.

Mike, thanks for the answer and information.
I reached out to SI, so far no answer from them.

Am I correct in understanding your answer - on a 2:1 screen, when projecting (with a 4K Sony VPL-VW1100ES projector) 16:9 and 2.35:1 content on a screen that's larger than the projected image - the SI Black Diamond will not work as a replacement to 4-way masking solution?

Best,
Shahar

It does a much better job than a white screen, but still not as good as actual masking. It is not a bad solution though. Some thing to keep in mind, SI's price increase goes into effect at the end of this month, here in the US. So if buying locally, you might want to check on this.
