I hope you have room lighting under control, because, due to the brightness of the projector, I'm recommending screens with a little gain, and that means white surfaces that can't reject side ambient light. If you are keeping the size small, say under 100" diagonal, and are on a tight budget (which I assume would be typical, since this is the least expensive home theater projector out there), then you might also consider the Elite HC Gray surface. The surface, I believe is available in motorized, pull-down, and fixed screen configurations. Not only is the Elite affordable, but it is a very light gray surface, without too much "HC - high contrast." As a result, it tends to work well with lower powered projectors, that need a bit of a boost in black levels. Because it is both low in contrast and light gray, it's not as effective as others in terms of ambient light, but still far better than a white surface in that regard.
Overall, the PH530, in my testing room (fairly dark walls), worked very nicely with my Carada Brilliant White screen (gain 1.4).
