This discussion covers the comparison of matte white and ambient light rejecting (ALR) screen materials. Using information on the projector make/model and preferred size, the customer was able to make a more clear decision.

[16:54] Customer: Hi, i was hoping to get some recommendations on screen material
[16:56] Rick: thank you for reaching out. I be happy to help.
[17:12] Customer: so, I am looking for a fixed screen, either 110in or 120in. I do most of my tv/movie/gaming in the afternoon or at night but during the weekend I do use my projector during the day.
[17:13] Customer: I do get ambient light in to the room so I was leaning towards ambient light rejecting material like your cine grey 3d/5d but I am worried about the viewing angle being too narrow
[17:13] Customer: I was wondering how much ambient light affects your normal white 1.1 gain material?
[17:15] Rick: Matte white screens do not reject ambient light. If you have ambient light presenting directly onto the material you will get about 75% of the image washed out.
[17:16] Rick: to combat this you may need to block out the windows and prevent the screen getting hit by direct light. Also, I recommend looking at this quick instructional videos on selecting the right screen material for your projection environment https://elitescreens.com/elitetube/Selecting_a_screen_material_for_my_home_theater_cc_720.mp4
[17:16] Rick: I also have this comparison video between our matte white and the Cinegrey 3D ALR screen https://elitescreens.com/elitetube/SableFrame_CineGrey3D_Comparison.mp4
[17:16] Customer: I have an Epson home cinema 2150
[17:17] Customer: ~2500 lumens
[17:18] Customer: So, if I do prevent light from hitting the screen directly but there is still ambient light in the room would you expect the image to be ok? also if I did go with Cinegrey would that allow me to keep my blinds open and still have a good picture?
[17:19] Customer: all the light comes from window on a wall to the left perpendicular to the wall I would place the screen in
[17:24] Customer: what would you recommend?
[17:26] Rick: According to the screen calculator - https://elitescreens.com/front/front/cms/slug/screen-calculator - your particular projector can achieve a 110-120” sized image with a throw distance of 13-14 feet, is stated by the manufacturer to be appropriate for use in low to average room lighting. That said, a matte white screen material may suit you just fine. If you prefer more brightness and performance, I recommend the ALR material. My only caveat is to make sure any ambient light source is not presenting light upon the screen from the same angle that the projector throws upon the screen.
[17:27] Rick: In other words, ambient light hitting the screen from the same angle as the projector, it will defeat the ALR capabilities of the screen.
[17:27] Customer: nice! thanks that was helpful
[17:28] Customer: which is the cheapest option in which CineGrey is available?
[17:28] Customer: looking for something in the 100-120 inch size
[17:33] Customer: also what is the difference between Cinegrey, CineGrey 3d and 5d and fixed frame?
[17:35] Rick: I will recommend the Sable Frame 2 series with the Cinegrey 3D

[17:33] Customer: Awesome! Thanks buddy.
[17:35] Rick: It was my pleasure. Thank you for choosing Elite Screens.
