The Acer PL6820 is a high-performance laser projector designed to deliver a sharp 4K UHD image with a native resolution of 3840 x 2160. Its DLP technology and 5500 ANSI Lumens of brightness ensure that visuals remain clear and vibrant even in rooms with ambient light, while HDR10 support adds depth and detail to the colors. With a contrast ratio of 50,000:1 and a refresh rate of up to 120 Hz, it provides smooth motion and deep blacks, making it a reliable choice for detailed presentations or immersive media playback. Setting up the device is flexible thanks to a 1.7x optical zoom and a vertical lens shift of +50%, allowing you to position the projector without moving the unit itself. You can project an image ranging from 0.533 to 7.6 meters in size from a distance of 1 to 8 meters, with manual focus and zoom adjustments to fine-tune the picture. The image can be further squared using vertical and horizontal keystone correction of ±30° each, ensuring a straight projection regardless of the angle. Encased in a white ABS plastic housing, the unit weighs 4.9 kg and measures 337 x 265 x 122.5 mm. It features a versatile connectivity suite including two HDMI 2.0 ports, a VGA input, an RJ45-LAN port, and two USB 2.0 ports for various source devices. Integrated 15 W dual speakers provide immediate audio, while the laser light source offers a long lifespan of up to 30,000 hours in low brightness mode, reducing the need for frequent maintenance.
