Also been on the phone with Stewart about a potential screen, and the guy went on about the contract ratio a given screen yields. According to their Excel spreadsheet found here, the only screen that comes close is the Firehawk G3, because the recommended contrast is 75, and it yeilds 71... actually their Firehawk SST yeilds 86 with the most lumens, but it claims it's not compatable with my lens(?). So is this screen contrast a lot of nonsense or what?
Well, I have a Firehawk G3, and I've been thinking about switching to a StudioTek G3. Its amazing how much the room can affect the perceived contrast on the screen. I'm in the process of identifing parts of the room that reflect back on the screen - and eliminating them.
When viewed a few feet from the screen, I was surprised at the amount of sparklies on the 130, and quite a bit more on the 170.
As you know, the Hi-Power is just reflective without any visible sparkly material on the surface.
I have a High Power screen ( 2.8 gain ) that I used temporarily. I could occasionally see a random bright " sparkly " on that screen too. What counts is can you see screen sheen or other artifacts from your chosen viewing distance ? Any screen with any gain can show itself to some degree. Which is why purists go with the Stewart StudioTek 100 / Snowmatt screen. Unfortunately, you need a room that is lined / floored entirely with black velvet for that screen to work!
