IOGEAR GCS1808H 8-Port USB HDMI KVM Switch with Audio (TAA) Review
The GCS1808H is IOGEAR's TAA-compliant 8-port rack-mount HDMI KVM switch with 2.1 surround audio, built for control rooms and government/enterprise IT environments that need HDMI over the older VGA-based GCS1808.
At $599.95 this is a premium rack-mount unit: steel 1U chassis, front and rear USB and audio jacks, Video DynaSync EDID emulation to keep displays from losing signal when switching, and cascading up to 512 computers across multiple units. TAA compliance makes it a fit for government and federal procurement where the base GCS1808's VGA-only design or non-compliant competitors won't pass. Password-protected OSD access adds a layer of security for shared server rooms.
Built for Compliance-Sensitive IT
TAA compliance and password-protected OSD access make this a fit for government and enterprise procurement requirements.
EDID Emulation Prevents Display Drop
Video DynaSync keeps each computer's display output stable even when its monitor isn't actively selected, avoiding the black-screen problem common on cheaper HDMI switches.
