LG CineBeam S PU615U 4K UST Laser Projector

The 4.3″ wide, 6.3″ high, 6.3″ deep, and 4.2 pound LG CineBeam S PU615U 4K triple-laser ultra short throw projector runs their webOS 24 smart TV platform. (It lacks an ATSC TV tuner and RF input to connect an antenna to receive over-the-air local television stations.) With 500 ANSI lumens of brightness and an unheard of 450,000:1 contrast ratio, it projects a 40″ to 100″ diagonal image onto a flat, smooth wall or an optional ALR (ambient light rejecting) screen, covering up to 154% of the DCI-P3 color gamut.

While you will get the best possible picture by projecting onto an optional ALR projection screen, its wall color adjustment feature lets you choose from 8 color presets to correct color imbalance to match a wall’s hue even if it’s not white. Either way, the darker the room, the better the picture!

The LG CineBeam S automatically aligns the image and sharpens focus in seconds. You can also easily scale and/or shift the image to fit your space without moving projector. Also features digital keystone correction edge adjustment.

Connectivity includes HDMI/ARC, two USB Type-C, WiFi, and Bluetooth. (Connect an optional Bluetooth speaker or sound bar for better sound than the built-in speakers.) Apple AirPlay 2 and Android Screen Share. Remote control.

You can purchase your LG CineBeam S PU615U either [directly from LG] or [at Amazon.com].
