A PROJECTOR/SCREEN FOR A TV?
Are you asking if such is possible, or even advisable? If so the answer is a resounding "yes".
I've been looking at the Screen Innovations Black Diamond screens for the past 5 years, and I even helped a friend of mine install his (BD III 1.4 106" 16:9) last summer. I like the screen, but there was some sort of structure there that annoyed me and has been keeping me from going to a projector/screen for a TV. It wasn't the pixels - perhaps it was grain? Anyway, I happened to stumble on the "Black Diamond 1.4 vs. DIY" and "The Official Silver Fire V.2 Thread" last week, which has given me hope for doing a projector/screen combo as a TV.
A lucky stroke! We honestly feel we have surpassed the BD line-up some time ago...in fact, we were at that sort of thing and doing it well before SI-BD products ever hit the street. The Sony Chroma Vu screens were our first goal...done on a dare. 2004.
MY EXISTING TV:
I currently have a Pioneer Elite Pro-710HD rear projection crt TV, which I have enjoyed for the past 13 years. The black levels are simply amazing on this TV. However, I sometimes wonder what a larger screen would look like in my room, which brings me here
It's one of those great rooms - a family room connected to a dining area, connected to a kitchen, all in a straight-line row. The family room is 14.5' wide, and goes about 15'-16' deep, where it then widens to about 20' for the dining area and kitchen. Total distance from family room front wall to kitchen is about 45'. Ceiling is 9'. The family room has four recessed canned lights (65W each). The dining area has a fan with a light fixture, and the kitchen has 6 recessed light fixtures (65W). Along the left side of the room is the wall that looks out to the back yard. Two sets of windows - the first is about 8' from front family room wall, and the second is about 16' from family room wall. Another few feet further, just before the kitchen, is a glass arcadia door. I have shutters on the windows, so I can vary the light coming into the room, as well as directing that light towards the ceiling or towards the floor. I have tan painted walls, and a white ceiling. This is why I was considering the BD screens - so that it could handle the daytime viewing, as well as night viewing with lights on.
Well you said you've seen a BDIII 1.4 in action. I doubt it was stuck doing a job under your set of circumstances. In any case, if proper installation considerations are met (below) and the PJ (5020) is mated with the right SF v2.5
formula, your going to see both a better, clearer image, and one that is every bit as dynamic.
1) I don't want a huge screen - I'd rather have a smaller screen, so that the picture will have more brightness and will be sharper.
Excellent thinking...to a point. You do want to have a immersive image though.....
2) I do not want any more than a 12" post connected from the ceiling mount to the projector. I do not want the projector any lower than that.
No issues there
3) I want the bottom of the screen to be 24" from the floor. My current TV is 22" from the floor, and having it lower is more involving. The only problem with this is that I need a projector with enough lens shift to accommodate #2 above. Let me know what you think about this...
Your preferred PJ will easily accommodate that criteria.
4) For daytime viewing, if there's not enough contrast on the screen, then I'd prefer to have a TV for daytime and a projector for night. I'm hoping that with an SF screen and an Epson 5020ub projector, the 2400 lumens will be enough.
Under ideal mounting, it can do a great job for you....but even with all that said, your not deepinto a safty zone with the type of room illuination your suggesting you might want to have.
Speaking of projectors, I originally wanted a JVC projector, so that I could get really great blacks. Two issues with the JVC - lumen output and lens shift. There's not quite enough lens shift to satisfy #2 and #3 above - something would have to give. Also, the light output might not be enough to look good enough for daytime viewing - even in high lamp mode. I thought about the Sony HW50es too, because it has more light output, but the lens shift is even less capable. That's why I'm thinking of the Epson 5020ub. It has the lens shift I need, along with the light output and decent blacks. I'm hoping the fan is not too loud, if I utilize high lamp/dynamic modes for daytime viewing. Any other thoughts/suggestions here are welcome.
The ONLY other choice I could suggest that would ace out your needs above and beyond the potential the 5020 offers is the BenQ SH940
1080p / DLP
50,000:1 "DLP" contrast
4000 Lumens / 3000 on Econo
H&V Lens Shift
Based on your room conditions, and what I can see as your having very lofty expectations (ie:demands) the BenQ mated to a SF v2.5 5.0
would give you a image equal to your Flat Panels if you shot it onto a 100" Fixed Screen. Actually, at 100" it will make your Flat Panel look shabby by comparison....especially when the extreme increase in size is factored in.
1) 100" 16:9 screen - a good size for my family room. Hopefully, will have the brightness and sharpness I'm looking for.
Brother, no matter which PJ you choose, the 100"er is your best choice. (...but you should strongly consider 110" diagonal 16:9...maybe in a Zero Edge design...)
Yes, you could go 2.35:1 CIH, but even with the conservation of Lumen output, you'd be so far behind the BenQ option as far as on-screen brightness (...and high ambient light contrast...) it absolutely ludicrous to make a comparison.
So let's get silly.
Epson 5020 @ 100" diagonal from 13' -7" & at normal lamp output on a 1.0 gain surface : 24 fls
BenQ SH940 @ 100" diagonal from 13' -7" & at normal lamp output on a 1.0 gain surface : 122 fls.
I mean really.........can you take sage advice here and accept you have something beyond spectacular waiting for you?
I know the BenQ, I've seen it do incredible things with a High Contrast screen....at 175" diagonal. At 100"s ....you can run it until it grows whiskers on Low Lamp, and still have a image comparable to the brightest Plasma you've ever seen, and the added Contrast enhancement of the SF v2.5 5.0
's dark Silver/Gray will make the PJ's 50K:1 CR seem like 500K:1
WHERE TO GO FROM HERE?
As a test, I'd like to get a piece of the Sintra/Komatex board - say 2'x3' or so - and apply the SF to it. I can then use it in my home, with a projector, and see how it does during the day and with various lighting configurations. From there, I can then decide on which of the three options would be best. Can anyone recommend how to make the SF paint? Which mixture would work? How to do it? Please feel free to respond to any of the above.
Reality check. You can't buy Sintra in anything smaller than 4' x 8' and you'll need 85" x 48" for 98" diagonal. Also, SF v2.5 5.0
is not a mix you can reduce the components down to get a 1 Quart Mix. You might as well go ahead and paint out a full size Screen. Really, only that will help you determine how happy you'll be.
You might as well because I gotta relate a stinker fur ya. Even if you wanted to have 2.35:1 CHI so bad it made you cry, unless you can mount the 6020 w/A-Lens so that the top edge of the A Lens is even with the top of the screen, it will not work if you try to employ Lens Shift...unless the A-Lens can move in syncro with the PJ Lens.
Since you do not want the big ol' Epson with a bulky A-Lens hanging down so far you have to feel like you have to duck under it, it's automatically ruled out.
Wow...you just saved $3800+ ! Get the BenQ and paint your full sized SF v2.5 5.0
screen. You'll get all the rest of the help you need once you make your decision known.
Your welcome Dave.
And be totally assured, I stand firmly behind my recommendation, every bit as much as if it was a Commercial application for an important Client. I know it will not just work well, it will astound you.
Never mind how much it cost, nor how much you saved....it's all about you being gloriously happy, supremely satisfied, and coming back on here to rave about it.
........and you will.....you will.
