Planar PD8150 Projector: Screen Recommendations
The very good black levels are further enhanced by using a high contrast gray surface. I spent the bulk of my time watching movies and sports on the Planar, on my Firehawk G3, and found I preferred it to watching on the Carada Brilliant White. The Carada (similar to the Stewart Studiotek 130 which is considered the industry standard, by most), had more pop, but with a projector in this class, I'm assuming as a top of the line single chip DLP, that owners have paid the bucks for, among other things, pretty black blacks. The Firehawk G3 really helps. Subjectively, using the Firehawk, compared to a white surface screen, lowers black levels, and, ultimately gives you a more "higher end" projector feel, than watching on a white surface.
Of course factors like your room ambient light (and where it comes from), as well as screen size comes into play during your decision making process.
I think, the real issue here, is that with a bit over 600 lumens in best mode, it has the power to handle my Firehawk, filling all of its 128" diagonal, something more than half of the home theater projectors we review just can't do. And with that screen, blacks while not the very best around, are very respectable.
Still, unless you have a compelling reason, I'd recommend sticking with some level of high contrast gray surface, whether something like the Firehawk G3, or perhaps a lighter gray surface, such as found on some Elite, Da-lite, Draper, and other screens.
