Video Distribution Amplifier Buyer's Guide
Video distribution amplifiers enable you to send a signal from a single input to several other display components. The DA, also referred to as a splitter, boosts your signal, making sure its strength doesn't weaken or degrade while being transferred to each receiver and over longer distances. This ensures the images sent to each monitor or television are uniform and of high quality.
Distribution amplifiers are designed for all types of video formats. You need to make sure the DA you purchase matches the signal and cable connection of your components. The ones you're most likely to encounter are:
- VGA
- HDMI
- Component video
- Composite video
- DVI
VGA distribution amplifiers
A VGA distribution amplifier is used for transferring computer video signals to two or more monitors. They come with 2, 4, 8 and 16 ports, so you can send the same image to multiple displays.
HDMI distribution amplifiers
HDMI distribution amplifiers are used for sending high definition signals to two or more HD displays. They also come with 2, 4, 8 and 16 ports, and conveniently allow you to transfer both audio and video signals via one cable.
Component distribution amplifiers
This distribution amplifier comes with one component and 2, 4, 8 or 16 component outputs, so you can send both your high definition and analog video signals to multiple receivers.
Composite distribution amplifiers
Composite video distribution amplifiers use common RCA cables to distribute signals from one analog source to several different analog displays.
DVI distribution amplifiers
DVI DAs also send one source of high definition video to several displays. They're most often used to connect computers with DVI graphics to several DVI-compatible monitors or projectors.
