I did some searching on the website were i bought the screen and by the description in find there ( it's in dutch sorry bout that ) :
Da-Tex doorzichtdoek: translucente, grijze vinyl; reflectiewaarde 1,8, kijkhoek 30º L/R, gewicht ca. 490 gr/m² en dikte ca. 0,26 mm. Naadloos tot 4,8 meter breedte.(Op bestelling)
... it seems to be a gray vinyl screen with a 1,8 gain, so i'm guessing i need ascreen that is less refelctive then that to get rid of the hot spotting.
The screen i have now is also grey, should i go for a white screen next time or not?
I realy know nothing about screens, and it looks like i spend 450 euro's on a screen now that does not work well with my projector, so i would like to hear wich screens you guys are using in combination with the hw20 that do not have the hot spotting, im in holland doh, so i hope the brands you are using will also be available in the eu aswell, but that is something i will have to search for as soon as i have some brands ;-).
Thanks in advance for the feedback.
