With up to a 140-inch screen at 4k UHD resolution (3840 x 2160), the HU70LAB displays at high precision and detail with realistic picture quality. Wheel-less LED technology bypasses the shortcomings of conventional projectors such as discoloration of LCD and the rainbow effect** of DLP for rich and deep color. Mount the projector on the ceiling-with Remote Focus and an improved zoom of up to 1.25x, you can easily adjust the size of the screen with the included LG Magic Remote without relocating the projector. HDR Dynamic Tone Mapping optimizes picture quality frame by frame, while TruMotion generates animation frames between existing one for a more fluid look and feel. Control using your voice with Google Assistant and Alexa built-in. Use Miracast to project content from your mobile devices, and pair with Bluetooth devices such as speakers and headphones. XPR Technology is based on Texas Instruments' 4K/UHD DLP technology that helps projectors to achieve true 4K resolution with 8.3 million pixels. **Rainbow effect caused by color wheel.
