Verdict

The BenQ GP20 is a portable ultra-lite LED projector featuring a native WXGA (1280 x 800) resolution, 700 ANSI lumens of brightness, and a high 100,000:1 contrast ratio. It is designed for versatility with a short-throw ratio of 1.2:1, allowing it to project a 40-inch image from just one meter away, and includes dual 3W SRS surround sound speakers for an all-in-one multimedia experience. Its main pros include an exceptionally long-lasting LED light source (up to 30,000 hours in Eco mode), MHL-enabled HDMI for mobile device charging, and robust connectivity options like USB and SD card slots for computer-free playback. However, it is noted for some cons, including visible scaling artifacts at native resolution, a heavier weight (1.5 kg) compared to some ultra-portable rivals, and brightness levels that may struggle in rooms with significant ambient light.
