Adder ADDERView PRO Review
The Adder ADDERView PRO AV4PRO-DVI is a 4-port dual-link DVI desktop KVM switch with USB 2.0 and analog audio switching.
It's Adder's entry point into its PRO desktop switching line - a single-head, DVI-only unit built for desks that need basic switching between machines without paying for the multiviewer engineering of the CCS-MV4224 or the DisplayPort silicon in newer switches.
The Budget Entry to Isolated Switching
Among the secure switches in this catalog, the AV4PRO-DVI is the most affordable, trading DisplayPort/HDMI support and simultaneous viewing for a straightforward, single-active-port DVI switch that still isolates each channel.
DVI Still Has a Home
Plenty of enterprise workstations shipped with DVI outputs well into the 2010s and remain in service; the AV4PRO-DVI lets those desks add basic isolation without forcing a video card or monitor upgrade.
Comparison to Alternatives
Versus the ADDERView Multi-Viewer (CCS-MV4224) - that adds simultaneous quad-screen viewing at roughly 7x the price, unnecessary for desks that only view one machine at a time. Versus the Vertiv Cybex SC840DVI-400 - a NIAP-certified 8-port DVI secure switch, worth it if formal certification or more ports are required. Versus the ATEN CS1922 - a cheap 2-port consumer switch with no isolation, fine only where security isn't a concern.
