StarTech SV431HDU3A2 (HDMI / 4 Computers / 1080p / USB 3.0 Hub / ~$355) Review
The StarTech SV431HDU3A2 is a 4-port HDMI KVM switch with a built-in 3-port USB 3.0 hub, 1080p video, and 3.5mm stereo audio switching for around $355.
USB 3.0 is the headline feature here — most budget HDMI KVMs cap peripherals at USB 2.0 speeds, so this one is worth it if you're moving files through an external drive or dock connected to the shared hub. 1080p is the ceiling, though, so it's not a fit for 4K workstations. Versus the TESmart HKS0401A1U — that's a cheaper 4-port HDMI KVM but sticks to USB 2.0 for peripherals, worth it only if you don't need the faster hub. Versus StarTech's own SV431DHD4KU — steps up to 4K30 and dual monitors for roughly double the price.
USB 3.0 Hub Is the Draw
A 3-port USB 3.0 hub on the console side means external drives, dongles, and docks plugged into the switch keep full 5Gbps speed regardless of which of the 4 computers is active — something a lot of competing HDMI KVMs at this price skip in favor of USB 2.0.
1080p Ceiling
Video maxes out at 1920x1080@60Hz. That's plenty for office and admin work but a hard limit if any connected machine outputs 4K — the switch won't pass that resolution through.
