I removed the tilt (whoops, didn't know) and centered the projector with the screen and am using slight lens shift to make up for about 3.5" difference from the middle of the lens to the top of the viewable portion of the screen. This helped image quality significantly. My problem is with the sparkles. The Firehawk G4, arrived with a dead IR sensor, a used remote, and when the screen retracts, the right side is higher than the left by about a 1/4-3/4". On top of that, my girlfriend, who is a Film Editor, sat down for the first time and said "what are all those sparkles?" That was her first impression of the screen/projector. I'm talking to Stewart, and the lads up there are very helpful, but I paid several thousand dollars more to "NOT" have these issues. I'm spending a lot of time that I don't have trying to rectify the issues. I'm too busy now with the holidays, but If the sparkles don't ease up, this thing is going back. I'm hoping the coating will settle or something as there is a strong smell of chemicals from the screen when it drops down.
I have a Sony VPL- V600es on high lamp mode, in the dark, struggling to put out a bright/vivid picture. If I had to do it all again, I would go with a STK 130. I debated on this for four months and my gut was telling me to do STK130 for the brighter picture. Even though I'm in a non-batcave environment, this is my living room, a Hollywood Hills loft, 1930's spanish building with darker stained beams and floors, brick walls and two lighter coloured walls. I have no interest in watching movies with the lights on or during the day without treating the windows. To those of you debating, the Firehawk is just too dim of a picture. With the lights on, the image doesn't wash out as much as other screens, but it's still not that watchable... This was my hesitation all along and I was right. Get the STK130 and treat your room as much as possible.
