Kensington SD1700P vs UH1440P - Mobile Dock Comparison 2026

Kensington SD1700P vs UH1440P: two very different mobile-dock ideas

The Kensington SD1700P and Kensington UH1440P are both driverless USB-C mobile docks. Each connects through a built-in cable, relies on DisplayPort Alt Mode for video, offers Gigabit Ethernet, and accepts a separate USB-C charger for laptop power. That shared baseline matters if you need something that works without DisplayLink installation or extra graphics software.

The buying decision starts once you look beyond that baseline. The SD1700P is built around newer Windows dual-4K desk setups. It has two HDMI 2.0 outputs, three 10Gbps data ports, up to 100W pass-through charging, and a Qi surface that can wirelessly charge a compatible phone at up to 10W. Its $139.99 MSRP reflects that more specialized feature set.

The UH1440P is a lower-cost, mixed-monitor travel dock. It has DisplayPort, HDMI, and VGA outputs, three USB-A ports, audio, SD and microSD readers, up to 85W pass-through charging, and a $59.99 MSRP. Its ceiling is much lower: one 4K display at 30Hz or two 1080p displays at 60Hz. That is enough for documents, hoteling desks, projectors, and basic office monitors, but it is not a modern dual-4K dock.

Short verdict: The SD1700P wins for a compatible Windows laptop that needs dual 4K60 HDMI, faster 10Gbps USB ports, more pass-through power, and a Qi charging pad. The UH1440P is the better fit when the desk has older connectors, card media, or a VGA projector and dual 1080p is sufficient. Both require a USB-C port with DisplayPort Alt Mode, and neither is the answer for a MacBook that needs extra displays beyond its native limit.

Quick specs comparison

Display support: the SD1700P is the clear capability pick

This is the largest difference between the two docks. The SD1700P has two HDMI 2.0 ports. Kensington lists dual 4K at 60Hz for Windows hosts that support HBR3 with DSC 1.2. A compatible host can therefore connect two current 4K displays without adding adapters. It also supports one 4K60 display through either HDMI port.

There is an important condition in that Windows claim. A USB-C connector alone does not guarantee the necessary video bandwidth. The laptop must provide DisplayPort Alt Mode with HBR3 and DSC 1.2. If it does not, a display can run at a lower mode or one output may not work as expected. This is a native video dock, not a USB graphics dock that creates additional displays through a driver.

The UH1440P takes a more conservative approach. Kensington specifies one 4K display at 30Hz, or two 1080p displays at 60Hz. That makes it a reasonable portable choice for email, browser work, spreadsheets, and ordinary office use, especially where the monitors are already 1080p. A 4K panel at 30Hz is less comfortable as a main display for long days because motion and cursor movement can feel less fluid than at 60Hz.

The UH1440P still has an advantage for display connector variety. Its DisplayPort++, HDMI, and VGA outputs are practical at a hoteling desk or conference room. You can pair DisplayPort with HDMI or VGA for dual displays, according to Kensington’s listed configuration. The SD1700P has only HDMI outputs. It is cleaner for a desk with two HDMI monitors, but it does not solve a DisplayPort-only monitor or a legacy VGA projector without another adapter.

macOS needs special attention with either choice. Kensington explicitly limits the SD1700P to one external 4K60 display on macOS; its dual HDMI ports can mirror but do not provide two extended displays. The UH1440P also uses native video, so it does not bypass the external-display limit built into a given Mac. A base Apple Silicon MacBook that natively supports one external display remains limited to one with either dock. If multiple extended Mac displays are the requirement, start with the best docking stations for dual monitors rather than assuming a second physical connector solves it.

Display winner: SD1700P. It reaches dual 4K60 on the right Windows host and single 4K60 where the UH1440P tops out at 4K30. Choose the UH1440P instead only when its DisplayPort, HDMI, and VGA combination matters more than resolution and refresh rate.

Ports and everyday desk use

The SD1700P has a focused collection of desk ports: two HDMI 2.0 outputs, two USB-A 3.2 ports, one USB-C 3.2 data port, Gigabit Ethernet, and USB-C power input. Kensington rates each of its data ports at 10Gbps. That is a useful step up over a basic mobile dock if you move files to an external SSD or use fast USB peripherals. Its separate USB-C power input can pass through up to 100W to the host.

The UH1440P has a broader but slower port mix. It provides three USB-A 3.2 ports, Gigabit Ethernet, a 3.5mm combo audio jack, SD and microSD card readers, and a USB-C power input. Kensington lists the dock at 5Gbps. It has no USB-C data port, so USB-C accessories will need an adapter or a direct laptop connection. For a photographer transferring UHS-I SD media, someone who uses a wired headset, or an office that still presents from VGA, the extra built-in connections are worth more than the SD1700P’s faster USB path.

Neither model includes a power brick. The SD1700P can pass through up to 100W and Kensington recommends pairing it with an 85W or higher USB-C Power Delivery adapter. The UH1440P can pass through up to 85W with a suitable charger. Actual charging remains dependent on the charger, cable, and laptop negotiation. Buyers with a high-power laptop should confirm what their notebook accepts over standard USB-C Power Delivery before treating either mobile dock as a replacement for a dedicated workstation charger.

The SD1700P has one feature the UH1440P does not try to match: an integrated Qi charging surface. With external USB-C power connected, it can charge a compatible phone at up to 10W while the dock is in use. In bus-powered mode, its toggle switch makes you choose between dock operation and Qi charging. That is sensible for a shared desk, but it is not a wireless charger that remains fully independent of the dock’s power situation.

The practical trade-off is simple. The SD1700P is more useful for a current USB-C desk with HDMI monitors and fast peripherals. The UH1440P is more useful for an unpredictable desk with legacy video, media cards, and analog audio. Neither has a card reader or audio jack on the SD1700P side, while the UH1440P has no USB-C data port and lower USB bandwidth.

Port winner: depends on the setup. The SD1700P is stronger for 10Gbps USB, USB-C peripherals, laptop power, and Qi charging. The UH1440P is stronger for DisplayPort, VGA, audio, and SD or microSD access.

Software, host requirements, and compatibility

Both docks avoid DisplayLink and Silicon Motion software. That is an advantage for people who want a native USB-C setup without installing a graphics driver or approving macOS screen-recording permissions. It also means the video result follows the laptop’s own graphics hardware and USB-C implementation.

The requirement is the same for both: the host USB-C port must support DisplayPort Alt Mode. A data-only or charging-only USB-C port cannot send video to the dock’s displays. USB4 and Thunderbolt ports normally provide the necessary video path, but the laptop documentation is still the right place to confirm display support.

The SD1700P lists Windows 10 or later, macOS 11 or later, and Samsung DeX for compatible Android devices. Its detailed platform limits are clear: Windows can use its dual-4K mode with HBR3 and DSC; macOS gets one external 4K60 display; Samsung DeX gets one external display at up to 4K60 subject to the device. iPad and DeX users should not buy it expecting two extended screens.

The UH1440P lists Windows 10 or later, macOS 10.15 or later, and Samsung DeX. Its ChromeOS notes are host-dependent rather than a firm compatibility claim. Its native design likewise preserves the host’s display limit. The significant difference is that its published display ceiling is already dual 1080p, so it is a less demanding option for older office monitors but not a better solution for high-resolution work.

Both products have limited feedback evidence in their YAML records. The SD1700P had a 3.1-star average from four global Amazon ratings during research and the UH1440P had a 4.5-star average from four global ratings. Those tiny pools do not establish a meaningful reliability pattern. Buy from a seller with a return window, then test the monitor modes, Ethernet, charging, and the specific peripherals you rely on right away.

Value and the score difference

At $59.99 MSRP, the UH1440P costs much less than the $139.99 SD1700P. It also has the slightly higher editorial score, 6.9 versus 6.5. That score reflects a coherent value proposition: a compact, driverless dock with Ethernet, media readers, audio, and connectors for mixed office displays. It does not mean the UH1440P is technically more capable.

The SD1700P costs more because it targets a different desk. Dual 4K60 HDMI support on a compatible Windows system, 10Gbps data ports, 100W pass-through, an integrated Qi pad, and a three-year warranty are tangible upgrades. The trade-offs are equally tangible: it has no DisplayPort, VGA, audio, or card readers; it needs a separate charger for full charging and simultaneous Qi operation; and its body is relatively heavy for a travel hub.

The UH1440P remains the better value for someone whose screens are 1080p and whose work needs card slots, a headset jack, or a VGA fallback. It has a two-year warranty and uses 5Gbps USB, but its lower price leaves room for the right charger or a small adapter if necessary. It is not a bargain substitute for a dual-4K60 dock. It is a different kind of mobile tool.

Verdict: choose the SD1700P for modern Windows dual-4K desks

The Kensington SD1700P is the overall winner because it supports a clearly higher display tier on a compatible Windows host, has 10Gbps USB connectivity, passes through more laptop power, includes a longer warranty, and adds a Qi charging surface. It makes the most sense as a compact desk companion for a laptop with the right USB-C video capabilities and two HDMI 4K monitors.

The Kensington UH1440P should not be dismissed. It is the practical alternative for a lower-cost mobile setup where displays are 1080p and connectors are inconsistent. Its DisplayPort, HDMI, VGA, audio, SD, and microSD coverage is much more useful than a higher-resolution HDMI-only dock in the wrong room.

Choose the Kensington SD1700P if:

• Your compatible Windows laptop needs two 4K60 HDMI displays.
• You need 10Gbps USB-A and USB-C data connections.
• Up to 100W pass-through charging suits your laptop.
• A built-in Qi charging surface would simplify your desk.
• You prefer the longer three-year limited warranty.

Choose the Kensington UH1440P if:

• Dual 1080p60 or occasional 4K30 is enough for your work.
• You regularly encounter DisplayPort, HDMI, and VGA displays.
• You need a 3.5mm audio jack or UHS-I SD and microSD readers.
• You want Gigabit Ethernet and three USB-A ports at a lower MSRP.
• Your priority is a mixed-monitor travel dock rather than a dual-4K60 desk dock.
