There have been a number of posts here which have called Draper M1300 material a 1.3 gain material. When I went to the Draper site, however, the gain chart for M1300 indicates that it is 1.0.


Which is it? Perhaps Draper is being conservative?


Anybody know?

I've wondered the exact same thing for the same reason. Hopefully somebody knows.

I just talked to the sales manager at Draper, he said the 1300 is a 1.0 screen.


Not sure what all the posts are referring to.


He mentioned that white 1.0 screen material is more than adequate for newer HD2 projectors. He said that older DLP models and their low contrast ratio where the reason to get gray material screens. Due to the higher contrast of the HD2, in his opinion, the 1300 is ok. He also told me about the 2500, which is a high gain material.


I personally have not decided yet. I am leaning toward one of three:

Firehawk (1.3)

Da-lite HCCV

Draper M1300 (maybe m2500)


Not trying to start a flame war here, just passing on what the manufacturer said.

I have a bunch of screen samples including M1300, and as far as I can tell, the gain seems about the same as all the other ~1.0 materials. So I would call it 1.0. Perhaps the "1300" in the name made people assume the gain was 1.300 :)

It used to be 1.3 a couple of years ago, but they changed it to one I think because it actually goes from slightly positive to slightly negative across the viewing angle, and averages to 1. They did the same with M2500, which was rated as 2.5 and is now rated as 2.1.
