Computer Applications for Baluns
Baluns are routinely used in conjunction with laptops, computers, and PCs, especially in education, church, and corporate presentation applications. They may be used to send either display (VGA, DVI, etc.) or control (PS2, USB, etc.) signals. Generally, the computer will either have a HD15 or DVI video connector and will output a VGA resolution as the main signal format. Different baluns support different resolutions: it is important to determine your signal's bandwidth and overall distance when selecting a balun.
