Maximum Cable Lengths
April 16, 15 - Posted in: Tech Talk
The DocKtor often gets asks, "What is the maximum USB cable length?" or "What is the maximum length of HDMI, VGA, & DVI cables?" Targus has validated using the in-box 1m cable (ACC987USX) with the Targus USB3.0 extension cable (ACC985USZ) to 13 feet between the PC and the dock. All other interfaces (ports, connections) conform to their respective specifications. Calculating the theoretical maximums using timing diagrams would be misleading because connector and cable quality vary widely. The DocKtor realizes this is not much of an answer, but that is because the specifications do not specify a maximum length: CAT6 and CAT5 are 100m.
