The ISO-MAX VBH-5BB reduces ground current induced video interference such as "hum bars" by a factor of over 100, eliminating the visible effects of these types of interference. The high bandwidth and low VSWR prevent degradation of the picture quality due to high frequency roll-off and cable reflections.
When used with a D15HDM-5BF-3 VGA breakout cable, this is a great solution to eliminate hum from any VGA system.
