IOGEAR GCS22U

Here is a closer look at IOGEAR GCS22U.

About

A pure legacy-analog VGA KVM for institutional, lab, and industrial holdouts that never migrated off analog video — mitigates the impedance-mismatch "ghosting" typical of VGA transmission well enough to sustain 2048x1536 with native DDC2B display identification support. A molded cable design eliminates rear-connector loosening over time, and it draws parasitic power directly from the VCC pin on the USB output lines rather than needing an AC adapter.

Max resolution
2048x1536

Ports: 2× VGA (entrada), 2× USB Type-A (entrada), 1× VGA (salida) and 2× USB Type-A (salida)

Confirmed with

  • Notebook (generic)

    Mixed evidence: a 2014 review confirms use with a "Dell Laptop with windows 7", but a separate report documents total failure with an older IBM ThinkPad T-42 ("nothing show's up") due to a DDC2B protocol handshake failure on switch.
