Q. I am interested in setting up a portable indoor/outdoor theater using a Nebula Cosmos projector. What screen do you recommend? I see Nebula has a new Cosmos Laser 4K projector. How does it compare to the Cosmos Max 4K?

A. Look for a smooth PVC screen with 1.1 gain. I use a JWSIT 120-inch indoor-outdoor screen ($178) that snaps securely to a frame and has two strong legs with two feet at each end. When used outdoors these feet can be secured to the ground with supplied anchors. The picture quality is fantastic and I have never had the desire to upgrade to a more expensive screen. The screen and legs fold up and fit neatly into the supplied carrying case.
