Frequently Asked Questions


Monitors may begin flickering when they receive a signal of insufficient quality. There are a few potential fixes available that will help to improve the signal quality in order to eliminate flickering:

  • Replace Video Cables with high-quality Video Cables (e.g. upgrade DisplayPort 1.2 Cables to DisplayPort 1.4 Cables).
  • Use shorter Video Cables to reduce signal attenuation.
  • When possible, remove Video Adapters to use native Video Connection Types (e.g. go from VGA to VGA, or DisplayPort to DisplayPort)
  • For DisplayPort Monitors, try changing the DisplayPort Version on the Monitor. For information on how to change your Monitor Settings refer to the Manual from the Monitor Manufacturer.
  • Update the Drivers for the Computer’s GPU to the latest available from the Monitor Manufacturer.
  1. Ensure the video & USB cables are connected between each computer and the KVM switch
  2. Safely power off all computers.  Unplug everything from the KVM switch and connect one computer at a time, swapping the inputs previously used (e.g., the computer connected to PC2 now connects to PC1). Power on each computer and confirm functionality before connecting the next one to the KVM switch. 
    • If using a KVM switch that supports multiple displays, ensure all video connections from the computer are from either the video card or motherboard, both cannot be used simultaneously on most systems.

Before You Buy

Cables and adapters that do not align to the size specification for DVI connectors may not fit properly beside one another on this KVM switch due to the spacing of the DVI ports. We recommend ensuring the connector is 39.5mm or smaller in width, as larger connectors may not properly connect beside one another. The cables listed in the Accessories tab are confirmed to be compatible with this KVM switch.

Excellent KVM for DVI

By: bobs - 12/18/2020
I bought this in May, 2020, and have only one complaint: The PC lights do not show which computers are active. Other KVM that I've used the PC (green) lights stay on steady if there is an active computer connected on that port, and would blink if the computer on the port is rebooting. This KVM only displays the light if you are on that port. So I can't tell if the computer on the port is active. My computers are under my desk so I can't see if they are on. So the only way I can tell is to switch between the computers. Not really what I want to do. That said, the switch works perfectly as a KVM.
