First, let's talk about size. Now I have a 127" 16:9 screen right now but due to limitations in my room, I'm unable to go too much bigger than that.
With that said, I have my mind pretty set on a 134" 16:9 screen. It's only just a few inches bigger than the one I have now so I doubt I'll have any issues with it whatsoever...
My question is this: I'm thinking about going with a Criterion Series frame, only because it's bigger than the Precision frame and I want to have as much maximum impact as possible when people see the framing of the screen. Does the 134" screen actually measure from WITHIN the frame (the inside of the frame) or does the actual 3.5" frame border count as part of the screen size?
In other words, if I went with a 134" screen, would it be 137.5" with the border, or would I actually be getting only 129.5 inches of screen, plus the 3.5 extra inches of the frame? This is quite important as I do have space issues.
My second question: How do people with fixed screens keep them clean? Obviously with pull-down screens, one can leave the screen up 99.9% of the time and only bring it down when watching a movie. My room is very, very, very dirty. It's a garage that has tons of dirt everywhere. I have a fixed screen now which is just screen material that I nailed to the wall and it is super dirty, filthy, disgusting and it can not be cleaned because it's horrible material. Knowing what I know about how much dirt can gather on the screen, it's important to know how I would go about cleaning it. Obviously, my best option would be a pull-down screen, but if other people can have fixed-screens, then there MUST be some sort of way of keeping them clean or at least cleaning them when they need to. How do you all keep your screens clean and/or how do you clean them when they get dirty?
Finally and probably most importantly, let's talk about the screen gain. Now I read a professional review out there on Carada screens and something really shocked me to the core. I don't have the review anymore, but I'm sure that if we looked hard enough, it would be easy to find. According to the professional reviewer, the screen material that Carada uses actually absorbs 40% light output.
What this means of course is that getting the ideal 1.0 screen gain for the truest image possible is completely out of the question. I've always wanted to go with a 1.0 screen only because it's the most truthful image you can get out of the projector. But if what this professional reviewer says is true, then that means that the Classic White 1.0 screen that Carada offers is actually more like a 0.6 screen because of the 40% light absorption and I don't need to tell all of you how untrue the image would be if that were the case.
I also understand that Carada makes a Brilliant White screen which has a screen gain of 1.4. Now again, my understanding is that when dealing with higher screen gains, especially at sizes we're talking about here, the screen will have all sorts of horrible "hot-spotting" everywhere you look, plus the blacks will be gone to produce a much brighter/vivid looking picture, but black level is extremely important to me.
With that said, I myself would never go with anything above a 1.0 screen due to hot-spotting issues and incorrect colors when you're dealing with a screen throwing more light output than is ideal back at the audience.
But... according to the reviewer who says that the material they use absorbs 40% light output, I am wondering if perhaps the 1.4 screen again of the Brilliant White will actually go down to a normal 1.0 gain after the light has been absorbed. Thus, this would be the perfect screen.
BUT... if the reviewer is wrong and the material does NOT absorb light, then I end up with a screen that is just way too bright and un-natural.
So... so you my dilemma. Just how accurate are Carada screens when they list their screen gains? Does this professional reviewer have any validity to his claims?
