Use multiple screens at once with this video-wall controller from StarTech.com. Thanks to its four female inputs, it works as a video splitter to project one HDMI (high-definition multimedia interface) source across four monitors. The controller's video-wall function combines your display into one large-format screen. This makes it a good choice for managing signage for a shop window or broadcasting media across multiple screens in an entertainment system.

• Uses EDID (extended display identification data) emulation to provide the same resolution across all connected displays
