The cables that you use when connecting your computer to ATEN's MasterView KVM switches play a very important role in the quality of the communication between the PCs and the MasterView unit. ATEN's custom made cables are designed to provide the highest signal capacity along with the lowest signal loss. What this means, to you as the consumer, is that you will receive the highest quality video output even in the higher SuperVGA video modes. Without high-quality cables your system performance can be seriously inhibited. ATEN has invested millions of dollars into cable manufacturing to ensure the highest quality cables at the lowest possible cost. All ATEN cables are double shielded to prevent RF interference even in the most electronically noisy environments.
