StarTech SV231QDPU34K 2-Port Quad-Monitor DisplayPort KVM Switch

Overview

The StarTech SV231QDPU34K is a 2-port KVM switch built for operators who run dual quad-monitor workstations off a single keyboard, mouse, and monitor set — think network operations centers, video wall control rooms, and multi-system security consoles where switching between two PCs or servers needs to happen without touching a single cable. Each port supports up to four DisplayPort monitors at 3840 x 2160 resolution at 60Hz, so a full 4K quad-display layout stays intact no matter which connected system is active. With SV231QDPU34K on the desk, an operator monitoring VMS workstations and a separate management PC can flip between both full 4-monitor sessions with one hotkey press or a front-panel button.

Key Features

• 2 KVM Ports, 4 Monitors Each: Switch between two source computers while keeping all four connected displays active on whichever system is selected — no need to re-arrange windows or re-detect monitors after a switch.
• 3840 x 2160 at 60Hz per Display: Full 4K at a true 60Hz refresh across all four monitors simultaneously, so video wall or multi-camera VMS layouts stay sharp and motion stays smooth instead of judder-prone 30Hz fallback.
• DisplayPort 1.2 with HDCP 2.2: Passes protected 4K content without triggering blank-screen HDCP handshake failures — relevant if any connected source plays back protected media or uses a DP 1.2-dependent GPU output mode.
• 2x USB 3.0 Hub Ports at 5Gbps: Share USB peripherals — external drives, capture dongles, badge readers — between both connected computers at full SuperSpeed throughput, not throttled down to USB 2.0 rates.
• 4x USB Type-A HID Ports: Connect keyboard, mouse, and other human-interface devices once and have them follow the active KVM selection automatically across both hosts.
• Hotkey and Push-Button Switching: Change the active computer from the keyboard or the unit's physical button — useful when a monitor is out of easy reach in a rack or console mount.
• Steel Housing: A metal enclosure holds up to continuous rack or console duty better than a plastic shell, and helps with EMI shielding around dense cable runs.
• Compact Footprint (6.3 x 3.9 x 3.6 in, 2.2 lb): Small enough to mount under a desk or tuck into a console shelf without eating usable rack or desk space.
• External 100-240V AC Power Supply: The 12V DC / 3A adapter accepts worldwide input voltage, so the same unit works on US or international mains without a separate power supply.
• 36W Power Consumption: Low enough draw that it won't be a meaningful factor in a console's overall power budget.
• 0~40C Operating Range: Rated for standard office and control-room environments; this is not an outdoor or unconditioned-space rated unit.

Integration & Compatibility

SV231QDPU34K is built around DisplayPort 1.2 video and standard USB HID, so it integrates with any two DisplayPort-equipped workstations or servers that need shared quad-monitor output — a common pairing in network video recorder and VMS control-room builds where an operator toggles between a live-monitoring PC and an administrative or backup system. Because switching is instant at the hardware level, there's no software agent or driver dependency tying it to a specific VMS platform. For sites planning a full console build-out, pairing SV231QDPU34K with a KVM switch lineup review and a PoE network switch for the camera side keeps video and control infrastructure cleanly separated. Review the VMS architecture guide when planning how many operator seats and switch units a control room actually needs, and browse the broader StarTech catalog for matching cabling and adapter accessories.

Frequently Asked Questions

Q: How many monitors can the SV231QDPU34K drive per computer?

A: Up to four DisplayPort monitors per connected computer, each at up to 3840 x 2160 resolution at 60Hz.

Q: Does the SV231QDPU34K support 4K at full 60Hz refresh?

A: Yes — all four displays support 3840 x 2160 at 60Hz simultaneously via DisplayPort 1.2.

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

A: Either a keyboard hotkey combination or the push-button control on the unit itself.

Q: What's the USB hub speed on the SV231QDPU34K?

A: The two USB 3.0 hub ports run at 5Gbps SuperSpeed, shared between the two connected computers.

Q: What power input does the SV231QDPU34K require?

A: An external adapter accepting 100-240V AC input and outputting 12V DC at 3A, drawing up to 36W.

Q: What's the warranty on the SV231QDPU34K?

A: 2 years.

Jerry Tildsen

What stands out on the SV231QDPU34K is that it holds 3840 x 2160 at a full 60Hz across all four monitors on both ports — a lot of 2-port KVMs quietly drop to 30Hz once you stack four displays per source, and that's a visible difference on a live video wall.

Technical Highlights:

• 4K60 x4 per port: Both connected computers keep native 3840x2160/60Hz across all four displays — no re-detection lag or resolution renegotiation on switch.
• DisplayPort 1.2 + HDCP 2.2: Handles protected content handshakes cleanly, which matters if any source GPU or playback app expects HDCP 2.2 compliance end to end.
• 5Gbps USB 3.0 hub: Two SuperSpeed ports mean shared peripherals (external storage, dongles) don't bottleneck down to USB 2.0 speeds when switched between hosts.

Deployment Considerations:

• Steel housing and a compact 6.3 x 3.9 x 3.6 in / 2.2 lb footprint make this an easy fit under a console desk or on a rack shelf near the operator position.
• Operating range is rated 0~40C — this is an indoor console unit, not something to place in an unconditioned equipment closet or outdoor enclosure.

I'd spec the SV231QDPU34K for a security operations center console where one operator needs to flip between a live VMS monitoring workstation and a secondary admin or backup server, without losing the quad-monitor 4K layout on either side of the switch.
