  • [15:32] Customer: I have a question about screens
  • [15:32]        Rick: Certainly, how may I help you?
  • [15:33] Customer: I have an electric125h “Spectrum Electric” motorized screen and I am reading that these are not compatible with short throw lens projectors
  • [15:33] Customer: I’m looking for something similar with a white casing
  • [15:33] Customer: …and it must be compatible with short throw lens
  • [15:35]        Rick: Certainly, one moment please, as I bring up the information for you.
  • [15:35]        Rick: In order for a short throw projector to work with any projection surface, that surface must be perfectly flat.
  • [15:40]        Rick: UST projectors spread the image so much over a short distance that the slightest uneven levels in the screen will distort the projected content. A screen like the Spectrum electric  (electric125h) is not perfectly flat so it won’t work well with short throw projectors but it works great with standard “long” throw projectors
  • [15:43]        Rick: I have found two series that i can recommend. The model is TE125WH2B-E24, this is our CineTension B series, it is tension and compatible with short throw. https://elitescreens.com/front/front/productdetail/product/361
  • the second unit is from our Starling Tab Tension 2 series. here is the model that uses the CineWhite material STT120XWH2-E12 https://elitescreens.com/front/front/productdetail/product/53
  • Also here is a video that describes UST projector compatibility https://elitescreens.com/elitetube/UST_Compatibility.mp4  and an article that covers more on the topic https://elitescreens.com/front/front/newsdetail/news/355
  • [15:44] Customer: ok thanks. Now I know and I will consider buying  the Starling Tab Tension instead.
  • [15:44]        Rick: You’re welcome. Have a great day.
