BenQ GP20 Análisis | 85 Datos comparados

The BenQ GP20 is a portable LED-based projector that features a native WXGA (1,280-by-800) resolution, a 700-lumen brightness rating, and a shorter-than-average throw distance that allows users to project large images close to the screen. Designed for flexibility, it can operate without a computer by reading files directly from its 1.7GB internal memory, USB flash drives, or microSD cards, and it features an MHL-enabled HDMI port for charging and connecting mobile devices. While it functions well as a home entertainment projector and includes a loud 3-watt mono speaker, its weight of 3 pounds 14 ounces makes it heavier and slightly less portable for business travel than key competitors like the Acer K335 and the 3M Mobile Projector MP410. The projector receives an "Average" 3.0-star rating due to a few notable performance and image quality limitations. On the positive side, its pros include its highly versatile file-reading capabilities, the MHL-enabled HDMI port, and a long-lasting LED light source rated for up to 30,000 hours in Eco mode. On the negative side, its primary cons center on image quality; it displays prominent...

The BenQ GP20 Ultra-Lite is a highly portable, single-chip DLP projector featuring an innovative RGB LED light engine that offers an exceptionally long lifespan of up to 30,000 hours in Eco mode without any degradation in color or brightness. Roughly the size of a hardcover book and weighing only 3.5 pounds, it is highly optimized for "plug and watch" entertainment on the go. It provides diverse connectivity options, including dual USB ports, an SD card slot, legacy analog inputs, and an MHL-compatible HDMI port that can charge smart devices while streaming. Additionally, it ships with a functional padded carry bag, a wireless WiFi streaming dongle, and built-in stereo speakers, making it an excellent, self-contained solution for quick setups at a friend's house or in a hotel room. However, its focus on portability brings several distinct performance limitations. On the downside, its maximum light output is restricted to 700 lumens, requiring a completely dark room to maintain image quality. It lacks essential setup features like zoom, lens shift, and deep calibration controls, requiring physical movement of the unit to adjust picture...

The BenQ GP20 is a portable LED-based DLP projector featuring a native WXGA (1,280-by-800) resolution and an exceptionally long-lasting light source rated for 20,000 hours in Standard mode and 30,000 hours in Eco mode. It is highly versatile for PC-free operation, as it can read video, photo, audio, and document formats directly from an SD card, USB memory key, or its built-in 1.7GB internal RAM. Additionally, it features an MHL-enabled HDMI port to seamlessly connect and charge mobile devices. A notable highlight is its shorter-than-average throw distance, which projects a generous 48-inch wide image from just 56 inches away from the screen, accompanied by a surprisingly clear 3-watt mono speaker. However, the GP20 sits in the middle of the pack due to several performance compromises. Despite its 700-lumen specification, its color brightness is significantly lower than its white brightness, making images appear dimmer than expected and reducing the effectiveness of its 3D functionality. Image quality is only acceptable, displaying noticeable scaling artifacts at native resolution, visible step patterns in color gradients, a subtle greenish-yellow tint on white levels, and lower...

However, the projector falls short in absolute performance and portability when stacked against its peers. Despite its 700-lumen rating, its lower color brightness relative to white brightness results in a dimmer image than expected, making comfortable viewing limited to smaller screen sizes (around 44 inches) or highly dimmed rooms. On the technical side, users face visible scaling artifacts at native resolution, added patterns over close lines or dots, and text that is difficult to read below 7.5 or 9 points. The display also exhibits a minor greenish-yellow tint in white levels and skin tones, as well as visible step gradients in white, green, and blue. Finally, its heavier weight makes it less travel-friendly for business professionals compared to lighter alternatives like the Acer K335 or 3M MP410.

The BenQ GP20 is a portable LED-based DLP projector designed for home entertainment and mobile presentations, though it faces stiff competition regarding its overall portability and image quality. A key benefit is its short-throw lens, which displays large images from a close distance to the screen, alongside a long-lasting LED light source rated for up to 30,000 hours in Eco mode. It features excellent standalone flexibility, boasting 1.7GB of internal memory, an MHL-enabled HDMI port to connect and charge mobile devices, and the ability to play common files directly from USB drives or microSD cards. Additionally, it offers a well-performing 3-watt built-in mono speaker and displays notably fewer distracting rainbow artifacts compared to rival DLP projectors.
