The Acer HL6521Gi is a Full HD laser projector designed to deliver clear, high-resolution imagery for various environments. Utilizing DLP technology with a 0.47-inch chip, it produces a native 1920 x 1080 resolution and a 16:9 aspect ratio, supported by a dynamic contrast of 3.5M:1 for deeper blacks and brighter whites. You can rely on a brightness of 4000 ANSI Lumens in standard mode, which drops to 3200 ANSI Lumens in Eco mode to extend the laser light source's lifespan up to 30,000 hours. Its optical lens features a 1.1x zoom and manual focus, allowing for flexible placement with a projection distance ranging from 1.1 to 10 meters. Setting up the image is straightforward thanks to both vertical and horizontal keystone correction of ±25°, ensuring the picture remains rectangular even if the device is angled. The white plastic chassis houses a 10W built-in speaker and a versatile set of connections, including two HDMI 2.1 ports, one of which supports Audio Return. Wireless connectivity is handled via dual-band Wi-Fi, enabling you to mirror content using Miracast, Google mirroring, or the EZCast app. Weighing 3.3 kg and measuring 322 x 225 x 109.7 mm, this projector is a practical choice for those who need a long-lasting, high-brightness display for presentations or home cinema without the need for frequent lamp replacements.
