This customer almost made a huge mistake, buying an ultra-short throw (UST) projector and installing it 10 feet (9.5 ft too far away) from an incompatible projector screen.  Fortunately, the service department caught the mistakes and recommended an excellent alternative.

Here are the links used in the discussion:

Transcripts:

[22:02]        Rick: Thank you for choosing Elite Screens, how may I help you.

[22:03] Customer: Looking for a projection screen for a school project. The screen needs to be adaptable for Ceiling mount, (probably 120-135”) and I am interested in seeing how well it will work with an ultra-short throw projector about 10 feet away. What do you have/recommend?

[22:04]        Rick: UST’s must be within a few inches from the projection surface to work. What is the minimum throw distance of the projector?

[22:05] Customer: Ceiling would be 10-12ft. If that spoils it for UST, what do you recommend.

[22:06]        Rick: That will be too far for either a UST or short throw projector. Also are you looking into a 120 to 135" diagonal screen or for a specific size? What is the ideal screen size for you?

[22:08] Customer: Looking at your SRM Series (Manual) but it does state "Not compatible with Ultra/Short-throw Projectors"

[22:11]        Rick: Yes, even though the Manual SRM is fairly  flat for standard “long” throw projectors, it’s not flat enough for any short throw projectors. Because of the steep angle of incidence from short throw projectors, the material must be perfectly flat.  Even an incontinency in level of 1mm or so will greatly distort the image.

[22:12] Customer: Thanks - Appreciate the info. I was also referring to the "throw" distance of 10-12ft. Projector mounted in the ceiling in the middle of the room!

[22:13]        Rick: ah ok. Yes, that distance is for a standard long throw projector.  Short throw projectors must be a lot closer to the screen.

[22:17] Customer: How bad would the distortion be on a non-framed pull-down screen? Better question, do you have a pull down framed screen?

[22:24]        Rick: I recommend a frame screen for short throw.  There are no pull-down frame screens and since you are throwing from at least 10 feet, I’d stay focused on standard throw projectors.

[22:26]        Rick: For your school location, I strongly recommend this fairly new manual projector screen for large group presentations. This unit is not a spring tension screen but uses a bead chain clutch mechanism to deploy and retract. Much easier to work with. More durable and more reliable.

[22:26]        Rick: here is the link.

[22:27]        Rick: This manual screen is tensioned and uses our Cinewhite material that will provide a flat surface that will work better for short throw projectors but I am still concerned about your long throw distance. Here is a tutorial to let you know what I mean. https://elitescreens.com/front/front/newsdetail/news/355

[22:28]        Rick: This is a new product and currently we have 3 sizes in 3 different formats. 100" in a 16:9 format, the 113 in a 16:10 and the 120" in a 4:3 format.  What are your thoughts.

[22:29] Customer: THAT'S what I'm looking for.

THANK YOU VERY MUCH

[22:30]        Rick: You’re welcome, I almost forgot about this one. thank you for being really patient with me.

[22:30] Customer: Do you have cut/specification sheets for it? I see the care sheet and material sheet as well at the User Guide. Need to get something to my Architect.

[22:30]        Rick: Yes, here are the downloads for the Manual Tab-Tension Series
