W.

IMO any screen with gain has hotspotting and this is a silver screen with gain and reflective elements so it's definitely not a 'clean' 2D screen. I have an HP 2.4 Da-Lite screen as well for comparison and while that's a better screen for 2D from a 'clean' reflective elements perspective, the color reproduction isn't as good as that on the 5D.
For 2D I only use one projector which is set in ECO mode and I have the white level turned down to 13ftl from about 17-18ftl. Having one lamp age differently isn't an issue as I can recalibrate as time goes on with the Radiance units\Calman and both projectors will still match in their light output and color balance.
i think the easiest way to get riddof hotspotting is go curved.
Had for a while but dropped it down while i was waiting my omega filtters. I might Try it one more time maby some time if there comes superbly better silverscreens. Im bothered about the ghosting every silver seems to have, atleast based on samples compared to one i have.
Curved screen is pretty easy to do if you get yourself some metal/aluminiumin to make a frame and use some threaded
Rod on top and bottom attached to the screen material, just tie from the Sail holes if you have them on your screen material.
Then have some stoppers at left and right top and bottom of the frame at the screen edge level to force the threaded rod to bend backwards. Just have the frame mounted off the wall 20-30 cm with some shelf holderit so there is room for bendings.
After maskin the tie strings of the screen it even looks great and if and just if you wanna use backlight its easy to light some at the Back of the screen course its not that fixin.
Worked like charm, i loved it.
