DIY projector screens
In my other thread i talked about my projector. A toshiba TLP-S10 400:1 contrast, 1200 brightness, 800X600 native 4:3.
I have a 77'' pine frame on my wall painted flat black that i project inside. BUT i'm just shooting onto my appartment wall. I have seen others use high dollar screens, Paints, Cloths.
I paid $200 for my projector so a 200+ dollar screen is outa the question. Plus someday i will want to go to a 16:9 at least. I am more looking at the wallboard and grey paint options to fill in my border frame.
My question is, After doing this am i going to keep noticing a immprovement, or is it 6 or a half dozen of the other?
I wish there was somewhere i coul dtest drive screens.

Re: DIY projector screens
Well, you definitely don't want to use grey paint. I know others around here have recommended a spray paint you can get at most home centers which has a name like Screen White or something really obvious. Basically a super white matte. Seems like a good solution for you.
They flutter behind you, your possible pasts.

Re: DIY projector screens
The simplest matte white screen is probably drapery black out cloth stretched over a suitable frame. Typically available for about $6 per yard at your nearest fabric store. You can assemble a frame from canvas art stretchers, dimensional lumber, or pick up a 4'x8' sheet of mdf/plywood, cut it down to size and remove material from the middle to save weight, if needed. Google will find you instructions for stretching canvas over frame, which is what you're trying to do.
I've been running blackout cloth with my Infocus X1 for several years. I've had various samples of Carada and DaLite screen material sitting here for nearly as long...so far, I haven't gotten around to comparing the samples to the blackout cloth. I'm satisfied enough with the BO for less than $50 that I can't imagine the difference justifying the $500 or more that a Carada or DaLite would cost me. Maybe when I upgrade to a 1080p one day, I'll feel differently.
There's lots of different paint suggestions over at another forum. Behr Silver Screen may be what John is thinking of. People have tried all kinds of concoctions from pure silvers, to light greys, pure whites, blends of various colors. For paint, you'll need a suitably flat substrate and good technique to avoid seeing a texture or lap lines when you project on it.

Re: DIY projector screens
Elfmaze, what color is your wall now you're projecting onto? A gray paint will improve your blacks a little bit, but the image won't be as bright. I would probably use a white such as Behr Ultra Pure White, flat finish, from Home Depot. That's what I use for my screen.

Re: DIY projector screens
Currently the wall is white but i couldn't really comment on how white it accually is. I have noticed that my blacks are a bit washed out even with the rooms blacked out, but i was starting to have a feeling that the grey paint tricks could turn into a big expensive mess. I have heard of the behr UPW. might give that a try.

Re: DIY projector screens
The problem with your blacks is due to the low contrast ratio of the projector. 400:1 is very low compared to today's projectors.

Re: DIY projector screens
A friend of mine and I built a 300" outdoor screen with a canvas he bought off the internet and some 2" PVC for a frame. It works great and it makes for some great movie nights with the families. I brought it up because I think the black out cloth or a canvas would work great and can be done for $50 or less.
If you have not seen it everyone should check out www.backyardtheater.com for more idea on how to enjoy your projector!
Good Luck,
Bud |

Re: DIY projector screens
The best way to improve muddy blacks is to replace the projector. Unfortunate, but, I'm afraid, true.
If you're good with the wall as your screen, then a painted wall is about as good as it gets; they're generally flat, easy to clean, and easy to protect. And you've already trimmed it in 'nicely.'
My problem was that I needed my screen to be several feet out from the wall, and therefore also "acoustically transparent" that caused all sorts of problems for the DIY screen. (I ended up with gray cotton stretched on a PVC/iron pipe frame.)
