StarTech SV231DPU34K 2-Port 4K DisplayPort KVM Switch with USB 3.0 Hub

Overview

The StarTech SV231DPU34K is a two-port DisplayPort KVM switch built for workstation environments where you need to control two computers from a single 4K display, keyboard, and mouse — without re-cabling or reaching behind a monitor. It supports resolutions up to 3840x2160 at 60Hz, which means you're not dropping to 30Hz when you switch sources, and it includes a four-port USB 3.2 Gen 1 hub on the console side so your USB peripherals don't become a second switching headache. If you're running a dual-workstation security operations desk, a trading floor, or an engineering station where two machines need to share a single 4K display, this is a compact, direct solution. Explore the broader range of KVM switches if you need more ports or multi-monitor configurations.

Key Features

• 4K @ 60Hz via DisplayPort 1.2: Supports up to 3840x2160 at a full 60Hz refresh rate — not the 30Hz limitation you'll hit on passive adapters or older KVM designs. For color-critical workflows or high-density security monitoring dashboards, the difference is visible. Lower resolutions like 1920x1080 and 2560x1440 are also supported for legacy display compatibility.
• USB 3.2 Gen 1 (5Gbps) host interface: Each host PC connects via USB 3.2 Type-B at 5Gbps, which is fast enough to handle KVM control and hub data without creating a bottleneck when transferring files or streaming video feeds from connected USB devices.
• Four-port USB 3.2 hub on the console: The console side exposes four USB Type-A ports, so your keyboard, mouse, USB headset, and a flash drive can all stay connected simultaneously. Switch sources and your peripherals follow — no re-plugging between sessions.
• Hotkey and push-button switching: Both switching methods are supported. Push-button on the unit itself works for a clean desk setup; hotkey sequences let you switch without lifting your hands from the keyboard — useful in high-tempo environments where a physical button press breaks concentration.
• HDCP 2.2 compliance: Supports HDCP 2.2, which is required if either source machine plays protected 4K content. Without this, a non-compliant KVM will blank the display or downsample the stream.
• 2-channel stereo audio switching: Each host PC has a dedicated 3.5mm mini-jack input; the console side carries a single 3.5mm output. Audio follows the active source, so your headphones or speakers stay connected at the console without a separate audio switcher.
• Wide input voltage range (100–240V AC): The internal power supply handles universal mains voltage, so the unit works in North American and international rack environments without a step-down transformer.
• Compact desktop footprint: At 6.3 in wide × 3.9 in deep × 1.6 in tall and 1.3 lb, the SV231DPU34K sits unobtrusively on a desk or shelf without requiring rack space. Useful in control room environments where rack U-space is already allocated.
• MTBF of 60,000 hours: Rated mean time between failures provides a useful reliability baseline for 24/7 operational environments where KVM downtime interrupts workflow.

Integration & Compatibility

The SV231DPU34K connects to host PCs via standard DisplayPort 1.2 and USB 3.2 Type-B cables. It complies with USB 3.0 and DisplayPort 1.2 industry standards, which means compatibility with any modern workstation GPU that exposes a native DisplayPort output. The USB hub on the console side is backward compatible with USB 2.0 and USB 1.1 peripherals, though those devices will operate at their native speed rather than 5Gbps. HDCP 2.2 support extends compatibility to DRM-protected content pipelines. Operating temperature range is 0°C to 40°C — standard for climate-controlled office or control room environments. For pairing with an appropriate DisplayPort cable rated for 4K@60Hz, confirm cables are certified for HBR2 bandwidth. See the KVM switch buying guide for guidance on selecting the right port count and video standard for your environment. If you're building out a full workstation desk, pairing this with a USB hub or monitor arm keeps cable management clean.

Frequently Asked Questions

Q: What is the maximum resolution the SV231DPU34K supports?

A: The SV231DPU34K supports up to 3840x2160 (4K UHD) at 60Hz over DisplayPort 1.2. It also supports 2560x1600, 2560x1440, 1920x1200, 1920x1080, 1280x720, and 1024x768.

Q: Does the SV231DPU34K support audio switching?

A: Yes. Each host PC connects via a dedicated 3.5mm mini-jack audio input. A single 3.5mm output at the console carries audio from the active source to your headphones or speakers.

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

A: You can switch using either the physical push button on the unit or keyboard hotkey sequences — both methods are supported simultaneously.

Q: How many USB ports are available on the console side?

A: Four USB Type-A ports are available on the console side via the integrated USB 3.2 Gen 1 hub. All four switch together with the active source.

Q: What is the warranty on the SV231DPU34K?

A: The SV231DPU34K carries a 2-year manufacturer warranty.

Q: Does the SV231DPU34K require an external power supply?

A: Yes. The unit has an internal power supply that accepts 100–240V AC input and outputs 12V DC at 1.5A. A power connection is required for operation.

The detail I keep coming back to on the SV231DPU34K is the full 60Hz delivery at 3840x2160 — a lot of two-port KVM units in this price tier quietly cap 4K output at 30Hz, which is fine for static dashboards but noticeable the moment you're scrolling through logs or moving windows. If your operators are spending eight hours in front of this switch, 60Hz matters.

Technical Highlights:

• 4K @ 60Hz, DisplayPort 1.2: Delivers full UHD resolution at 60 frames per second — no frame-rate compromise compared to a direct GPU connection.
• 4-port USB 3.2 Gen 1 hub (5Gbps): Console-side hub handles keyboard, mouse, and two additional peripherals simultaneously at 5Gbps, eliminating the need for a separate USB switcher on the desk.
• 60,000-hour MTBF: At continuous operation that projects to roughly 6.8 years before expected first failure — meaningful for a device sitting at a 24/7 security operations or NOC workstation.

Deployment Considerations:

• Both host PCs require available USB 3.2 Type-B ports and native DisplayPort outputs — if either machine only has HDMI or USB-C, you'll need active adapters that meet HBR2 bandwidth requirements to maintain 4K@60Hz.
• Operating temperature ceiling is 40°C — this unit is not rated for unventilated equipment closets or industrial floor environments. Stick to climate-controlled control rooms and desk deployments.

The SV231DPU34K is the right pick for a dual-workstation security operations desk or a two-machine engineering station where both seats need access to a shared 4K display and a common set of USB peripherals — and where the operator cannot afford the friction of re-cabling to switch contexts.
