PB2120 specifications

The BenQ PB2120 is a versatile and robust projector tailored for both business and educational environments. With its compact design and solid performance, it serves as an effective tool for delivering presentations, lectures, and multimedia content.

One of the standout features of the BenQ PB2120 is its native SVGA resolution of 800x600 pixels. This resolution, while not the highest available in today's market, ensures that text and images are displayed clearly and with significant detail, making it suitable for displaying PowerPoint presentations, charts, and detailed graphics. The projector supports a range of video formats, allowing for seamless integration with multiple devices.

The brightness of the PB2120 is rated at 2000 ANSI lumens, which provides adequate illumination in varied lighting conditions. This high brightness level means that presentations can be delivered effectively even in rooms with ambient light, reducing the need for complete darkness. This is particularly advantageous in business settings where lighting is often controlled by the amount of natural light coming into a room.

In terms of connectivity, the BenQ PB2120 comes equipped with multiple input options, including VGA, composite video, and S-Video ports. This ensures compatibility with a wide array of devices such as laptops, DVD players, and even some gaming consoles, making it a versatile solution for users. Additionally, it features a built-in 2-watt speaker, providing audio support for presentations, though for larger audiences, connecting external speakers might be recommended.

The PB2120 incorporates advanced DLP technology, known for its reliability and clarity. DLP projectors are celebrated for their consistency in color reproduction and sharp image quality. The projector also features a lamp life of up to 4000 hours in economy mode, which reduces operational costs and maintenance concerns by minimizing the frequency of lamp replacements.

Ease of use is another key highlight of the BenQ PB2120. It includes an intuitive control panel and a remote control, making it user-friendly for presenters. The projector's lightweight design also ensures that it can be easily transported between locations, catering to users who require mobility.

In conclusion, the BenQ PB2120 is an efficient projector that combines essential features for effective presentations with user-friendly operation. Its adequate brightness, solid resolution, and DLP technology make it a reliable investment for professionals and educators alike. With its practical connectivity options and mobility, the PB2120 is designed to meet the demands of a dynamic presentation environment.
