Today I was at a home cinema studio to see the different projectors and screens. Combined with the JVC X500 I liked a screen with about 1,4 - 1,6 gain the most and I think it could fit the best in my room. What do you think?
What kind of mixture do I need for such a gain?
What does the number after "silver fire 2.5" mean? :-)
Thank you in advance.
The numerical designation after v2.5
stands for the number of ounces of Black Flame Colorant
added to the Silver Fire Reflective mix. N/C
means "No Colorant
A designation of 4.0
would mean 4 ounces...which would result in a darker Silver Grey mix than would a 2.0
As far as screens go, I don't know what you viewed Mfg / Model Screen, but I do know that most all such 1.4 to 1.6 gain
screens carry with them caveats that many find unacceptable. Price notwithstanding.
Then again, for some they represent exactly what they want, and things like graininess, color shifts, and limited viewing cones don't seem to enter into their thinking as far as being things that they cannot live with to get such increased brightness.
Silver Fire v2.5 N/C (
w/No Colorant & no added UPW ) will be well within the 1.3 gain range. By bumping up the White Pearl and UPW by a total of 8 oz Pearl and 6 oz UPW, you can get to 1.4 gain.
Beyond that, because of the use of Mica-based Metallic flakes, the quantities cannot be increased...either Silver or Pearl, without there being a too obvious increase in perceived Graininess. Those increases are usually only made in conjunction with very dark Silver Fire versions (6.0
) that are going onto Commercial screens of very large proportions, and whose images will be viewed from enough distance that the graininess is resolved into the background.
I have painted 110" to 120" Silver Fire
screens with gain in excess of 4.0
, and whose blacks were truly and awesomely "Interstellar" and whose Whites simply blazed like (dare I say it...) a real supernova. But the viewing cone was only about 30 degrees off axis (at best) and from 10 feet away I could plainly see enough granularity in the image to make it unacceptable to me.
For your stated screen size, and the fact that the JVC actually puts out a brighter image than it's specs would tend to infer, I don't think you would need anything that would go beyond the Silver Fire v2.5 N/C
