Video Extenders Information
In some situations, displays need to be located in a different location than the video source. Video Extenders help overcome the distance between the display and source by extending the video signal via wireless, wired or over a network. Video Extenders help to minimize video degredation, such as blurriness or blinking screens.
The video signal can be any number of formats such as VGA, HDMI, or DVI.
Often used for applications when multiple monitors are running off of one VGA port, such as schools and businesses, a VGA extender is an electronic device that increases the signal strength from a VGA port. VGA extenders are sometimes called VGA boosters.
An HDMI extender is a device powered with an external power source or with the 5V DC from the HDMI source. Active HDMI exenders use electronics within the cable to boost the signal and allow for HDMI cables of up to 30 meters (98 feet). HDMI extenders that are based on dual Category 5/Category 6 cable can extend HDMI to 250 meters (820 feet), while HDMI extenders based on optical fiber can extend HDMI to 300 meters (980 feet).
A DVI extender allows for the extension of the DVI-D connection to a computer monitor via SDI cables.
