I am planning to get an LT150, but I have some questions to LT150 owners related to screen size vs distance .


I will be seating between 12-13 feet away from the screen, the screen size (diag) will be around 120".

I have 100% control over the light in the room.


Is this consider too close to the screen ?

What is a good ratio (screen size vs distance) for the LT150 ?


Thanks for your help!

I believe you will be OK. I think the rule of thumb is to be two to three times the height of the screen away. I have exactly that setup you mentioned, except that the center seat is about 19 feet away. I have sofas on the side which would be at 12 feet away and the picture is not too big from there. I think 12 should be the closest you should be to the screen though, anything else might make the screen seem too big and would make hard to follow some scenes with high movement.

Ricky,


I have almost an identical setup. My LT150 is projecting about a 115" screen and I'm sitting 13 feet back. It looks great and I couldn't be happier. True theatre 'feeling' experience. If I do get closer, say 10 feet away the image starts to degrade and I can see all sorts of stuff that I do not want to see. http://www.avsforum.com/ubb/smile.gif So I think you should be ok.


Great little projector.

Ricky D,


Check out Cinema Source's Front Projection Screen Design Guide before finalizing your seating arrangement.


For most people the optimum viewing distance will provide about a 30 degree horizontal and a 15 degree field of view.

For a 4:3 display, this gives a viewing distance of only 2.5 picture heights (PH), while for a 16:9 display, the viewing distance is 3.3 PH.


For standard-definition video, scan-line visibility would be objectionable at this distance, so an upconverter would be needed to increase the no. of scan lines per PH, or one would have to remain farher back from the screen.


For HDTV, 30-degree viewing at 3.3 PH should be possible without scan-line visibility.

You better have 2W viewing distance to minimize the chance to see the dithering effect.

I have the ISCO II which allows me a closer viewing distance. I sit 1.2 screen widths away from a 92" wide screen. It is screen door that is the problem with sitting too close. At less than 2 screen widths away you will see the dark gaps between pixels.


Frankly I don't see the dithering effect because I havc not looked for it, and it has not jumped out at me.

perform with the HDTV?


RickyD, 12-13 feet is great, I have that setup, but i'm projecting on a flat wall right now.. heh.
