BenQ MU686 is just what you need to perfect your presentation in all settings. Boasting 3500 ANSI lumens and 20000:1 high contrast ratio, this WUXGA projector also offers auto vertical keystone correction for diverse display options to keep your presentations looking great! With WUXGA* native resolution up to 1920 x 1200, MU686 supports resolution from XGA, WXGA, Full HD to WUXGA, offering crisp and accurate images in all of your presentations. Conventional high-brightness projectors make a lot of noise. But, not the MU686, which pumps out 3500 lumens of ultra-high brightness with only 31dB of sound, even on full power. Silent and brilliant, your presentation will command the audience's full attention with no distractions. The 20000:1 high contrast ratio ensures that every text, image, graph, chart and video is projected with optimal clarity and enhanced sharpness, especially for numerical data. This enables presenters to view their presentation files clearly and allows the audience to stay focused on the contents projected. BenQ's exclusive 3D colour management tool ensures 100% uncompromised colour customization with the freedom to independently fine-tune the hue, grain and saturation levels of all six primary colours (R/G/B/C/M/Y). Auto vertical keystone correction enhances installation flexibility by correcting the trapezoid effect via vertical adjustments up to +-40 degrees. With it, the projector can be placed off centre and the presenter can stand in front of the screen without blocking the image. 1.3x Big Zoom feature frees up space with an impressive range of throw distances and projects images up to 300 wide, giving you the flexibility of placing the projector anywhere without compromising your current decor. Every detail of MU686 is optimized for business. Wireless streaming in Full HD resolution is activated with a touch of the Qcast button on both the projector and remote control. And a new control panel keeps all projector controls at your fingertips. The simple plug & play QCast WiFi dongle is even designed to plug into a hidden port, keeping the minimalist design uncluttered. With the support of MHL technology, you can stream content from your smartphone or tablet instantly. Simply connect your device via a MHL cable and watch the flawless mirroring of contents expand onto the projector screen.
