Gefen EXT-DPKA-LANS-TX Review

The Gefen EXT-DPKA-LANS-TX is a 4K DisplayPort KVM-over-IP extender sender unit.

This is Gefen's budget-friendly entry into 4K DisplayPort KVM-over-IP, noticeably cheaper than the Emerald EMD4000T or ATEN KX9970T in this catalog, a reasonable trade if you don't need those vendors' management software ecosystems.

4K DisplayPort at a Lower Entry Price

The EXT-DPKA-LANS-TX encodes 4K DisplayPort video and USB peripherals for network transport, undercutting the Emerald EMD4000T and ATEN KX9970T on price while still hitting genuine 4K resolution, though without those vendors' larger matrix-management software suites.

Sender Half of a Matched Pair

As the transmitter ('Sender') unit, it requires the matching EXT-DPKA-LANS-RX receiver in this catalog to complete a working extension link.

Comparison to Alternatives

The Emerald EMD4000T covers the same 4K DisplayPort ground with more enterprise IP KVM matrix features for roughly triple the price. Gefen's own EXT-DVIKA-LANS-TX (also in this catalog) drops to 1080p DVI for a lower-cost alternative if 4K isn't required.
