Marketing Information 
  • Quick setup. Just plug in your monitors and snap a few DIP switches.
  • The 300-MHz bandwidth gives you sharp images at any resolution: VGA, SGA, and XGA.
  • Kit includes three 10-foot (3-m) VGA output cables and one 6-foot (1.8-m) VGA input cable.

    Sharp images. Long-distance video distribution. The versatility to handle a variety of applications, in any kind of environment. These qualities-and more-have made the Black Box® VGA Video Splitter an industry favorite.

    A single splitter enables you to transmit displays from your CPU to up to four monitors 250 feet (76.2 m) away. And if you cascade multiple splitters, you can transmit to as many monitors as necessary. What's more, the 300-MHz bandwidth provides clear images at any resolution-VGA, SVGA, and XGA®.

    Setup is simple. Just connect the cables from all monitors to a splitter and flip a few DIP switches. That's all it takes to project what's on your PC's screen to multiple monitors.

The C920s Pro HD Webcam delivers remarkably crisp, detailed video in full 1080p HD at 30 frames per second. Diagonal, fixed, 78-degree field of view perfectly frames you and your space to make a strong impression in your video conference calls. Capture razor-sharp images and clear colors with the five-element, glass lens. Autofocus adjusts smoothly and precisely for consistent definition and fluid video. Flip the privacy shutter closed when you want to be off camera. Two microphones are located on each side of the camera to capture more realistic sound from a broader range of angles. Equipped with automatic HD light correction, this webcam used RightLight 2 technology to adjust to your lighting conditions for bright, contrasted images, even if you're in a dim setting.
