The VGA Extender SRN from Gefen is a distribution system that allows you to extend VGA signals by transporting them over CAT-5 Ethernet cable. The system consists of a transmitter that connects to your VGA source, which transports the signal over CAT-5 cable. The receiver then accepts this signal and translates to its original format for output. This unit supports transmission distances of up to 150'. Resolutions up to 1080p or 1920 x 1200 are also supported.
Matching your monitor's resolution and refresh rate capabilities with the KVM is crucial, as many budget switches cap out at 4K 30Hz or 1080p. Ensure it supports the exact number of monitors and computers you need. Available from $146.71.
KVM switches require very little electricity and have no consumables. Ownership costs are effectively zero beyond the initial purchase and required cabling.
Common Failure Modes
Port failure or signal degradation over time are the main issues. Active electronic components can sometimes fail, causing blinking displays or dropped USB connections.
