StarTech SV231TDVIUA 2-Port Triple-Head DVI KVM Switch

Overview

The StarTech SV231TDVIUA is a 2-port KVM switch built for operators running triple-monitor DVI workstations off a single keyboard, mouse, and speaker set. If you're staffing a security operations center, NOC, or dispatch desk with two triple-head machines — say a primary monitoring workstation and a backup or secondary analysis PC — the SV231TDVIUA lets one console control both without swapping cables or duplicating peripherals. Each port supports full triple-display DVI output at up to 1920x1200 per monitor, so operators keep their entire six-panel (3+3) layout intact when they switch sources. Switching happens via front-panel push buttons or keyboard hotkeys, and because the unit is OS-independent, it sits cleanly between Windows, Linux, or other platforms without driver dependencies.

Key Features

• 2 KVM Ports, 3 Monitors Each: Consolidates two full triple-monitor DVI workstations onto one shared keyboard, mouse, and monitor set — a real desk-space and hardware-cost saver for control rooms running redundant or primary/backup video monitoring stations.
• 1920x1200 Maximum Resolution per Head: Preserves full single-link DVI resolution across all three displays simultaneously, so switching sources on the SV231TDVIUA doesn't force a downgrade in your VMS or analytics client's on-screen layout.
• Push Button and Hotkey Switching: Operators can flip between the two connected PCs from the chassis or straight from the keyboard — useful when hands are already on the keyboard mid-incident and reaching for a separate switch box isn't practical.
• USB 2.0 Peripheral Support: Keyboard and mouse stay connected through the switch at USB 2.0 speeds, which is sufficient bandwidth for standard HID peripherals without adding latency to cursor or keystroke response.
• OS-Independent Operation: No software or drivers to install on either connected PC — the switch handles signal routing at the hardware level, so it works identically whether the attached systems run Windows, Linux, or another OS.
• Steel Chassis Construction: A steel enclosure holds up to continuous desk or rack-adjacent use in 24/7 monitoring environments better than plastic-housed alternatives, resisting the wear of years of switching cycles.
• Compact Footprint (6.3 x 2.9 x 3.9 in, 2.0 lb): Small enough to sit on a desk beside a monitor stand or mount out of the way in a console rack without eating into limited operator workspace.
• External Power Supply (100-240V AC In, 12V DC / 1.5A Out): Universal AC input means the SV231TDVIUA runs on standard mains power in any region without a voltage selector, and the 18W consumption is light enough to leave running continuously without adding meaningful load to a UPS-backed circuit.
• Operating Range 0C to 40C: Rated for standard indoor office and control-room environments — not intended for unconditioned outdoor enclosures, but well within range for typical server rooms or NOC floors that run warmer than a standard office.
• 0~80% RH Humidity Tolerance: Covers normal indoor humidity swings without requiring climate-controlled storage, useful for facilities where HVAC coverage isn't perfectly even across every room.

Integration & Compatibility

Because the SV231TDVIUA is OS-independent and switches at the hardware level, it drops into mixed-platform environments — a Windows-based VMS workstation and a Linux-based analytics box, for example — without compatibility concerns. It's a natural fit alongside network video recorders and multi-monitor VMS clients where an operator needs fast access to two independent triple-head systems from one control point. For broader background on building out a control room around a StarTech KVM and video distribution stack, a VMS architecture guide is worth reviewing before finalizing your workstation layout. If your monitoring setup also depends on networked cameras feeding those triple-head displays, pairing this switch with properly planned PoE switches for camera uplinks keeps the rest of the signal chain consistent. Storage planning for the recorders feeding these workstations is covered in a dedicated storage and retention guide, and if you're outfitting a full KVM switch lineup for a multi-seat control room, standardizing on the same switching hardware across desks simplifies spares and training.

Frequently Asked Questions

Q: How many monitors does the SV231TDVIUA support per computer?

A: Each of the 2 KVM ports supports a full triple-monitor DVI setup, for a total of 3 displays per connected PC at up to 1920x1200 resolution.

Q: Does the SV231TDVIUA require software or drivers?

A: No. It's OS-independent and switches at the hardware level, so it works with Windows, Linux, or other operating systems without installing drivers.

Q: How do I switch between the two connected computers?

A: The SV231TDVIUA supports both front-panel push-button switching and keyboard hotkeys.

Q: What's the warranty on the SV231TDVIUA?

A: It carries a 3-year manufacturer warranty.

Q: What power input does the SV231TDVIUA require?

A: It uses a universal 100-240V AC input with a 12V DC / 1.5A output power supply, drawing approximately 18 watts.

Q: What USB standard does the SV231TDVIUA use for keyboard and mouse?

A: It supports USB 2.0 for connected keyboard and mouse peripherals.

What stands out on the SV231TDVIUA is that it holds full 1920x1200 resolution across all three DVI outputs per port — a lot of triple-head KVMs quietly downgrade to a lower shared resolution when you're pushing three displays at once. I've spec'd this into control-room refreshes where the operator's six-panel layout (two triple-head PCs) needs to stay pixel-for-pixel consistent no matter which source is active.

Technical Highlights:

• 2 Ports x 3 Monitors: Covers two complete triple-display DVI workstations from a single keyboard, mouse, and monitor bank — no per-seat peripheral duplication.
• 1920x1200 Max Resolution: Full single-link DVI resolution holds on all three heads simultaneously, so nothing downgrades when you switch sources.
• 18W Power Draw (12V DC / 1.5A out, 100-240V AC in): Light enough load to run 24/7 on a UPS-backed control-room circuit without budgeting for it like an active network appliance.

Deployment Considerations:

• This is a DVI-only switch — confirm your source PCs and monitors are native DVI or that you're comfortable adding DVI-to-HDMI/DisplayPort adapters, since no other video type is listed in the spec sheet.
• USB 2.0 is fine for keyboard/mouse HID traffic but don't expect this to double as a USB peripheral-sharing hub for high-bandwidth devices; it's built for KVM control, not data transfer.

This is the switch I'd spec for a two-seat backup monitoring station — primary SOC workstation and a secondary triage PC, each running triple DVI monitors, sharing one operator console during shift handoff.
