A 4K projector is the ultimate tool for cinephiles or gamers who want to get the most out of their ultra-high definition films and games without getting into multi-thousand-dollar screens and burdensome furniture. Only the most expensive TVs can even come close to the literal scale of a projector's maximum screen size, and then you deal with the challenges of anchoring a 110-inch flatscreen. Moreover, 4K projection technology has evolved enough to fall significantly in price over the past couple of years. Spending a lot for the absolute premium models is still possible, but most of our recommendations will set you back under 2,000. A 65-, 75-, or even 85-inch 4K TV could still be the most cost-effective choice, but there's no denying that 4K projectors--like our best overall, the feature-rich XGIMI Horizon S Max--have become much more accessible and versatile.

Watching 3D films is already an immersive experience but a new projector promises to make it more of a physical activity too. XGIMI's Z4 Aurora projector features sensors that detect movement, allowing users to turn up the volume with a twirl of a finger or skip forward or backwards with the wave of a hand. The device features built-in Harman Kardon speakers to produce stereo quality sound and can stream movies sent to it from your phone or laptop using AirPlay and Miracast. The Z4 Aurora (pictured) claims to be the world's first gesture-controlled projector with a built in stereo. China-based XGIMI has designed the projector so it looks more like a turntable, meaning it can blend in more easily in the average living room.
