A great projector is the center of a home theater, but a few other choices decide how good the picture and sound end up.
Screen. Choose a screen size that fits your room and your seating distance, then check your projector’s recommended projection range to confirm it can fill that screen. A larger screen is where 4K resolution pays off most. Understanding Throw Ratio
Light control. Ambient light washes out contrast, so the less stray light on the screen, the better your picture looks. Blackout curtains or dimmable lighting help in any room. If you can’t fully control the light, look for a projector built to correct for it, like the W2720i with AI Cinema Mode.
Audio. Movies are half sound. Many projectors can pass audio to a soundbar or AV receiver over HDMI, so check your model’s audio options before choosing speakers.
Seating and placement. Plan where the projector sits (ceiling mount or table) before you buy, since placement affects the throw distance you need and the cable runs you’ll want to hide. Lens shift and keystone correction add flexibility if your ideal spot isn’t perfectly centered.
