IOGEAR GCS1934 (4-Port DisplayPort 1.2 KVMP Switch / USB 3.1 Gen1 Hub / Audio / TAA Compliant) Review
The GCS1934 scales IOGEAR's mid-tier DisplayPort 1.2 switching up to four computers, essentially a 4-port sibling to the 2-port GCS1932 with the same USB 3.1 Gen1 hub and audio switching carried across all four ports.
For buyers managing four machines on a single standard 4K DisplayPort monitor, the GCS1934 covers that need without stepping up to the 8K-capable CS1924A's higher price. TAA compliance keeps it viable for enterprise and government IT deployments the same way as IOGEAR's other compliant models in this range.
A Four-Port Take on the GCS1932
Same DisplayPort 1.2 and USB 3.1 Gen1 combination as the 2-port GCS1932, scaled to four computers for buyers who need more machines switched to one monitor rather than higher resolution.
Comparison to Alternatives
Against IOGEAR's own CS1924A, the CS1924A adds 8K resolution support at a higher price, the GCS1934 is the more cost-effective choice for standard 4K DisplayPort monitors. Against the GCS1904, an HDMI-adjacent alternative from IOGEAR's lineup, the GCS1934 is the DisplayPort-native four-port option.
