Vertiv SwitchView 300 Series (SV340DPH-400) (4 Computers / DisplayPort+HDMI / Secure Desktop KVM / $1,751.25) Review
The Vertiv SwitchView 300 Series SV340DPH-400 is a 4-port secure desktop KVM switch with DisplayPort and HDMI support at 4K@30Hz, isolated switching to block data leakage between connected computers, for $1,751.25.
Vertiv (formerly Avocent/Cybex) built the 300 Series for desks that mix security domains - a trader or analyst who needs strict isolation between a classified and unclassified machine but doesn't need the full NIAP certification of the Cybex Secure line. The premium over a consumer 4-port switch buys isolated USB/video paths, not extra features.
Isolation Without Full Certification Overhead
The 300 Series uses the same isolated-channel engineering as Vertiv's certified secure switches but skips the NIAP/Common Criteria paperwork, landing at a lower price for buyers who want data separation without a formal compliance mandate.
Mixed DisplayPort/HDMI Desks
Supporting both DisplayPort and HDMI on the same unit means IT doesn't have to standardize every connected PC on one video connector, useful when workstations are replaced piecemeal over several budget cycles.
Comparison to Alternatives
Versus the Vertiv Cybex SC840DVI-400 - that's the NIAP-certified secure line, worth the extra step for government or defense desks with a compliance requirement. Versus the Avocent SV240DPH (4-port) - that's the non-secure Avocent-branded sibling at a lower price for buyers who don't need isolated switching at all. Versus the ATEN CS1922 already in this catalog - that's a compact 2-port USB-C consumer switch, not built for multi-domain isolation.
