Since the LT150 has no zoom, I may be mounting the projector at the back of my room (13'). Has anyone experimented with screens larger than 100" (which seem to be the norm). Is there a problem with light dropoff or images getting too soft etc.


I'd check myself, but I'm still waiting for my equipment to arrive and will be doing a DIY screen (any size I want!).


regards,

chris

I would keep it under 84 inches.

 

[videohot]

ACK! I have a 86" wide screen ordered already. Not that 2 inches might make THAT much difference but...any other opinions?

I have a 100" screen and it looks great! I imagine it would look even better with a somewhat smaller screen, but the detail and clarity at 100" must be seen to be believed.


I would think a larger picture would become too dim long before its begins to suffer in clarity.


I'd probably say, stick with 110" or less.

Well, I watched about 30 mins each of Fifth Element, Gladiator, and First Contact last night with an image 96" across. I never even got around to hooking up audio because I was so impressed by the picture. NOTE: I have no frame of reference to compare that picture with above the 27" POS TV I have sitting below the screen.


1. Does that make me an official HT geek now?

2. How much is annual dues?

I have a 52" by 92" matte white screen (gain 1.0) and am using a 575 lumen SVGA Viewsonic. The image looks great.


As long as you don't have too much ambient light, I think that screen (and perhaps a bit larger) would be fine with the LT150 as well. YMMV.

My screen is 92 inches wide. The depth of the room is 13 feet. I was a little concerned when I bought the Hipower screen that it would be too big but I got a deal that was too good to pass up.


Well, it rocks. I've got a movie theatre in my home, which I've dreamed about since I was a kid. Yippee!


I think screen size is very dependent on personal taste.


Also -- Masking, as Grant has been saying, is important for getting the highest quality image.

I plan on ordering a 110" or a 106" diagonal high power da-lite for my lt-150. Hope its not too big.

Billy,


Are you using an LT150? How far from the screen is your projector mounted? Ceiling or table top? And how far from the screen do you sit?


Also, you mentioned your screen is 92 inches wide ( I assume this is width and not diagonal)? Is this 4:3 or 16:9?


Just wondering because my current viewing room is about the same depth as yours.

 

[Frode]

There's essentially two problems with image size in this case


- ambient light

- viewing distance


If you have trouble with ambient light you shouldn't have got a LT150 in the first place - it just won't look very good. I'd also think that most of us would be limited by height more than width and so there's a natural limitation on how large an image we can get. If you have ambient light control there's absolutely no chance of the image getting too dim due to size with your throw distance.


Viewing distance however can be a problem. Not because of screen door, but because the image is too large for the source resolution if you sit too close. You'll see every flaw possible on the DVD and possibly scaling artifacts (if you don't use a HTPC). In addition the image may be so large as to completely fill your view. This'll give you a crick in the neck usually - and a larger chance of seeing rainbows as your eyes flick over the image. How large is too large? Well this is a case of YMMV. Experiment. See what works best for you. Size isn't the most important thing here, comfortable viewing is.

Wondering about size... What are you guys doing with your LT150s? Progressive DVD at 480p? HTPC upconverting to 720p?


Does it start looking bad because of the pixels from the original image, or from the way the projector projects?

Sonny B,


Yes, I am using an LT150. Yes, the width is 92". My screen is 4:3 (92x69), but I actually only pull it down up to 16:9 due to room/stereo cabinet constraints. The screen is about 12 feet from the projector for widescreen material. When looking at 4:3 material I move the projector in a few feet and up a foot or so to shrink the image to fit the screen.


Currently I am using an empty box and books to match the correct height for the widescreen mode, until I think of a more aesthetically pleasing approach. In 4:3 mode I can use a low small table.


Seating is a large couch and a large chair on either side of the projector. Normal seating is 12 feet back, giving slightly more than a 1.5 ratio to the screen width. The front of the couch is at an angle and about 9 feet from the screen.


The couch and chair are moved in as close as possible, with the projector between them. Because the projector is below the seating position and between the upholstered material, it masks the noise a lot.


I am using a Radeon based HTPC so scaling is great. Per Frode's message, I do see MPEG artifacts. However, the 1.5 distance ratio makes for a very theatre-like field of view which my guests and I find terrific.


I wouldn't put a bigger screen in my space, but I also wouldn't use a smaller screen!


One way to think about screen size -- where do you like to sit in a movie theatre? In the front, in the middle, or in the back? I don't like sitting in the back. I like the middle or even closer.


Don't forget the masking. It makes a tremendous difference. With help from my girlfriend, I've come up with a velcro, felt, dowel, and screwhook system which is completely removable when not in use.

LT150 manual says 200" limit...but 100" or there abouts should be conservative enough with good ambient light control. http://www.avsforum.com/ubb/smile.gif

I have an SVGA Infocus with a 120 inch screen and it looks great. Having seen the LT150, I would think it would be fine at 120 inches.


Of course, this does depend on how close you want to sit. I think that any setup with an XGA system where you are sitting no closer than the screen diagonal is fine.


As to the theoretical limit, a projector will tend to focus to "infinity" if you like. It is a question of resolution and brightness. If you want to try it with a 50' screen, for example, I am sure it will focus well enough; the image will just not be bright enough.

 

[RobertWood]

One suggestion. Get your projector in first. Project the

image onto a white painted wall, bed sheet, etc.

Experiment with different image sizes and change your viewing distance. Then you'll have a much better idea of the screen size that's going to please you before you make your choice.

I have a Draper m2500 screen with 16:9 aspect ration, 133" diagonal in a totally light controlled room. It looks fantastic even with DVD 480p. Today, a friend brought over a laptop HTPC and blew us away with the improvement. I don't know if a screen larger than mine will look good with the LT150 though.
