IOGEAR CS1924A Review

The CS1924A scales IOGEAR's 8K DisplayPort KVMP switching up to four ports, letting a single 8K-capable monitor and USB 3.0 peripheral set be shared across four computers rather than the two the CS1942DPA covers.

Where most 4-port switches top out at standard 4K, the CS1924A carries the same 8K resolution ceiling as IOGEAR's 2-port 8K models, a genuinely rare combination of high port count and high resolution headroom in one switch. USB 3.0 hub sharing and audio switching apply across all four connected computers, and TAA compliance keeps it viable for government and enterprise procurement..00 it costs the same as the 2-port CS1942DPA, trading that model's dual-display capability for two additional computer ports instead, a straightforward choice depending on whether more monitors or more machines matters more.

8K Resolution at Four-Port Scale

Most 4-port KVM switches cap out well below 8K. The CS1924A brings IOGEAR's high-resolution DisplayPort switching to a four-computer setup, useful for professional environments standardized on a single high-end display.

TAA Compliance for Enterprise and Government Buyers

Like several other IOGEAR models in this lineup, TAA compliance opens procurement channels that rule out most consumer-grade KVM switches on sourcing grounds alone.

Comparison to Alternatives

Against IOGEAR's own CS1942DPA, the CS1942DPA supports two computers with dual-display switching, the CS1924A instead spreads that resolution ceiling across four single-display computers. Against the GCS1904, a standard 4K 4-port DisplayPort switch, the CS1924A is the pick specifically for 8K-capable display setups.
