Since you say you are using it in a non-dedicated room, whoever recommended the Firehawk did you a big favor. The Firehawk is a FANTASTIC screen for it's purposes. It always amazes me how beautifully it preserves contrast.
However, just because we are picky about technical stuff around here: it does hotspot. By nature it hotspots. It wouldn't work the way it works if it didn't. Most people don't notice or aren't bothered by it so in that sense to many it's a non-issue as it seems to be with you. But if you are sensitive to hot-spotting as a screen artifact (I am, as are some others here) then it's very easy to see hotspotting on the Firehawk with movie material, long throw or not.
I've found your posts regarding screens to be the among the most reasonable and balanced I've read, but I slightly disagree with you on this point.
The degree to which the Firehawk hotspots is affected by many variables, such as throw ratio, seating distance, seating angle, projector height, projection angle, etc...(lumens?). When I purchased my Firehawk screen, I expected
it to hotspot. The only question was how much, and whether or not it was worth the trade-off. I was pleasantly surprised to see no hot spotting in normal viewing. I've been looking for it. In movie after movie, I've been trying to detect it. Just a bit here or there. Maybe in a blue sky, a green field, a desert.... Can't see it. I strongly disagree that it's "very easy to see". I'm looking for it, and cannot find it. Maybe in another application- different distances, angles, lumens, etc....
As I've said, put up a 100% white screen and look for any lack of uniformity and you will find it. But, under normal viewing conditions
, in the correct application, you will not. (At least I don't) The ISF had no problem with it. The proper application is critical. I have no doubt people might see hotspotting in some situations. Stewart was very specific regarding my seating distances, angles, etc....
No question it's not the right screen surface for everyone. What bothers me is the blanket statement that it hot spots. "Focuses" might perhaps be a better term. "Hot spotting" scares some people off. People for whom this would be the best choice.
I understand the "no free lunch principle". Certainly there are trade-offs. Any screen with gain/optical coating creates a compromise. To say that this screen always hotspots would be just as incorrect as saying it never hotspots. There are "costs" to this screen.
Have you ever seen a Firehawk with a long throw ratio, proper seating angles and distances, and a high output projector like the Sony 1000?
