Kensington SD5560T vs SD5780T - Thunderbolt Dock Comparison 2026

Kensington SD5560T vs SD5780T: the short version

The Kensington SD5560T and Kensington SD5780T look like close relatives, but they solve different problems. The SD5560T is the older hybrid option. It connects over Thunderbolt 3 when the laptop supports it, and it can fall back to USB-C with DisplayPort Alt Mode when it has to. The SD5780T is the newer Thunderbolt 4 dock. It gives up the SD5560T’s explicit hybrid positioning and focuses on a more capable desktop setup with HDMI 2.1, faster Ethernet, and two downstream Thunderbolt 4 ports.

Our winner is the SD5780T. The product data gives it an 8.0 score versus 7.1 for the SD5560T, and the spec sheet backs that up. The SD5780T has 2.5 Gbps Ethernet instead of Gigabit, HDMI 2.1 instead of HDMI 2.0, an SD UHS-II card reader, a 1m host cable, and stronger display ceilings including 4K@120Hz through HDMI and dual 6K@60Hz on supported MacBook Pro or Max systems. It also keeps Kensington’s three-year limited warranty and 96W laptop charging.

The SD5560T is not pointless. Its advantage is flexibility for mixed desks. If one laptop has Thunderbolt and another only has USB-C Alt Mode, the SD5560T is built for that compromise. You still get charging, USB, Ethernet, audio, and one HDMI monitor on a USB-C host. On a Thunderbolt host, it can run dual 4K@60Hz through HDMI plus the downstream Thunderbolt 3 port. That makes it useful as a discounted office dock, especially when a newer Thunderbolt 4 dock costs much more.

For most people buying today, though, the SD5780T is the better long-term dock. Choose the SD5560T only if the price is meaningfully lower or the USB-C fallback use case matters more than faster networking, HDMI 2.1, and Thunderbolt 4 expansion.

Quick specs comparison

Why the SD5780T wins overall

The SD5780T wins because it is the more current dock in the areas that matter over several years of ownership. Both docks charge a laptop at up to 96W. Both avoid DisplayLink drivers. Both carry a three-year limited warranty. Those shared strengths make the comparison less about brand trust and more about port quality.

Start with the host connection. The SD5560T uses Thunderbolt 3. That is still a 40 Gbps connection on Thunderbolt hosts, and it is enough for dual 4K@60Hz in the configuration listed in the YAML. The SD5780T moves to Thunderbolt 4. The raw maximum data rate is still 40 Gbps, but Thunderbolt 4 gives buyers a newer baseline, two downstream Thunderbolt 4 ports, and a cleaner match for current Windows laptops and MacBook Pro models.

The second advantage is Ethernet. The SD5560T has Gigabit Ethernet. That is fine for ordinary office networks, but it is the older baseline. The SD5780T supports both 1 Gbps and 2.5 Gbps through its RJ45 port. If your desk has a 2.5GbE switch, a NAS, or a faster wired office network, the SD5780T is the only one of these two docks that can use it. Even if your network is Gigabit today, a dock is the kind of accessory people keep for years. Faster Ethernet is worth having.

The third advantage is display headroom. The SD5560T supports one or two 4K@60Hz displays on Thunderbolt hosts, with the second display using the downstream Thunderbolt 3 port. On USB-C Alt Mode hosts, the product data drops to one HDMI display, either 4K@60Hz on DP 1.4 HBR3 hosts or 4K@30Hz on DP 1.2 HBR2 hosts. That is a useful fallback, but it is not a full two-monitor USB-C solution.

The SD5780T has a better ceiling. Its product data lists single 8K@60Hz through a downstream Thunderbolt 4 port, single 4K@120Hz through HDMI 2.1, dual 4K@60Hz through HDMI 2.1 plus one Thunderbolt 4 downstream port, and dual 6K@60Hz for compatible MacBook Pro or Max chipsets. Most people will use dual 4K@60Hz, but the extra modes matter if you own a high-refresh 4K monitor or plan to keep the dock through another monitor upgrade.

The SD5560T can still be the rational buy if price leads the decision. Its $269.99 MSRP is lower than the SD5780T’s $399.99 MSRP, and the YAML notes that Kensington marks the SD5560T as out of stock and points buyers to a replacement SKU. That makes it a product to buy carefully, not a product to chase at full price. If a retailer discounts it heavily and your setup matches its limits, it can make sense. At normal pricing, the SD5780T is easier to recommend.

Display support and monitor setup

Both docks use native display output. That matters because neither product requires DisplayLink software, and neither carries the usual DisplayLink trade-offs around drivers or protected streaming video. The downside is equally important: neither dock creates extra display pipelines for laptops that do not support them.

The SD5560T is straightforward on Thunderbolt. Use HDMI 2.0 for one display and the downstream Thunderbolt 3 port for the second display. The YAML lists dual 4K@60Hz on Thunderbolt 3 or Thunderbolt 4 hosts. That is enough for many office desks, especially if the second monitor accepts USB-C or you already own the right Thunderbolt or USB-C display cable.

Its USB-C fallback is more limited. Kensington’s product data says USB-C Alt Mode hosts support one HDMI monitor. DP 1.4 HBR3 hosts can reach 4K@60Hz through HDMI. DP 1.2 HBR2 hosts are listed at 4K@30Hz. The downstream Thunderbolt 3 port drops to USB 2.0 without video or daisy chaining on USB-C Alt Mode hosts. In practice, that means the SD5560T is a good one-monitor USB-C dock and a good two-monitor Thunderbolt dock. It is not both at the same time.

The SD5780T is better if your laptop has Thunderbolt 4, Thunderbolt 3, or USB4 and your display setup is more ambitious. HDMI 2.1 gives it a 4K@120Hz single-monitor path. The two downstream Thunderbolt 4 ports give you more room for the second display, storage, or a Thunderbolt accessory chain. The YAML also lists dual 6K@60Hz on supported MacBook Pro or Max chipsets, which is a clear step above the SD5560T’s dual 4K ceiling.

Mac buyers need to pay attention to the same Apple Silicon caveat on both products. The SD5560T product data says base Apple Silicon MacBooks are limited by the Mac model’s native display support. The SD5780T product data calls out base M1, M2, and M3 MacBooks as limited to one external display. If your MacBook only supports one external monitor natively, neither dock fixes that.

Ports and everyday desk use

The SD5560T has a compact but older port mix. You get two USB-C 3.2 Gen 2 ports on the front, four USB-A ports, Gigabit Ethernet, a 3.5mm combo audio jack, one HDMI 2.0 output, and one downstream Thunderbolt 3 port. Kensington includes a 0.8m passive Thunderbolt 3 cable and a 180W power supply. That covers the basics: keyboard, mouse, webcam, Ethernet, headset, laptop charging, and one or two displays depending on the host.

The missing pieces are the reason it scores lower. There is no SD or microSD card reader. There is no 2.5GbE. There is no DisplayPort connector. There is only one dedicated HDMI output. None of those are dealbreakers for a basic office desk, but they matter once you add media workflows, faster local networking, or mixed monitor inputs.

The SD5780T has a more premium port list. The YAML shows two downstream Thunderbolt 4 ports rated at 15W each, one HDMI 2.1 output, four USB-A 3.2 ports, a 2.5GbE-capable RJ45 port, a 3.5mm combo audio jack, and a UHS-II SD 4.0 card reader. It also includes a longer 1m Thunderbolt 4 cable. There is still no microSD reader, which gives the CalDigit TS4 and some other docks an advantage for tiny media cards, but having a full-size UHS-II SD reader is still better than the SD5560T’s no-card-reader setup.

The SD5560T does have one practical desk advantage: its hybrid design is easier to share with older or cheaper laptops. If your home office sometimes hosts a Thunderbolt MacBook, sometimes a Windows ultrabook with only USB-C Alt Mode, and sometimes a Chromebook, the SD5560T’s product data is written around that reality. It will not give every host the same display experience, but it can keep the desk functional.

The SD5780T is the better dock when the laptop is good enough to use it fully. A Thunderbolt or USB4 laptop gets the more modern video path, faster network option, better Thunderbolt expansion, and the SD card slot. If this dock will live beside a MacBook Pro, Dell XPS, ThinkPad, Surface, or HP business laptop with real Thunderbolt support, the SD5780T is the better fit.

Power delivery is a tie

Power delivery does not decide this matchup. Both docks provide up to 96W to the host laptop from a 180W external power supply. That is enough for most ultrabooks, business laptops, and many 14 to 16-inch productivity machines during normal work.

The SD5560T lists 96W host charging through the upstream port. The SD5780T also lists 96W through the Thunderbolt 4 cable. If your laptop needs more than that under sustained CPU and GPU load, neither Kensington dock is the right answer. You may need to keep the original charger connected, or look at workstation docks with higher vendor-specific power delivery.

Accessory charging is different but not decisive. The SD5560T has one USB-C port rated at 20W, one USB-C port rated at 7.5W, and USB-A ports rated at 4.5W. The SD5780T has two downstream Thunderbolt 4 ports rated at 15W and a front USB-A port rated at 7.5W. The SD5560T may be nicer for a phone on the front USB-C port. The SD5780T is nicer if you use downstream Thunderbolt accessories that need bus power. Neither replaces a dedicated fast charger for a tablet or phone.

Compatibility: hybrid flexibility versus newer Thunderbolt

The SD5560T’s best argument is compatibility breadth. Kensington lists Windows 10 or later, macOS 11 or later, and ChromeOS 91 or above. The dock can connect to Thunderbolt hosts for the full 40 Gbps and dual-display experience, but it can also fall back to USB-C Alt Mode for a simpler one-display setup.

That fallback comes with clear rules. USB-C Alt Mode hosts get one HDMI display. USB-C laptops without DisplayPort Alt Mode get no video output. The downstream Thunderbolt 3 port loses video and daisy-chain features on USB-C Alt Mode hosts. Base Apple Silicon MacBooks stay limited by Apple’s native external-display support. These caveats are not hidden flaws. They are the compromise that makes a hybrid dock work without DisplayLink.

The SD5780T is less about fallback and more about being a better dock for current Thunderbolt laptops. Kensington lists Windows 10 or later and macOS 11 or later. The YAML says USB-C only laptops can connect for peripherals and charging through the HDMI output for a single display, but dual display and 40 Gbps Thunderbolt data speeds require Thunderbolt or USB4. It also notes a specific issue on some AMD Ryzen laptops where a second monitor may not work through a Thunderbolt downstream port with a USB-C to DisplayPort adapter, with a workaround involving native Thunderbolt or a certified active Thunderbolt-to-HDMI cable.

For a mixed fleet, the SD5560T is easier to justify. For one good Thunderbolt laptop on a serious desk, the SD5780T is the stronger product.

Price and value

At MSRP, the SD5560T is much cheaper: $269.99 versus $399.99 for the SD5780T. If both docks sold at MSRP and your desk only needed one HDMI monitor on USB-C or dual 4K on Thunderbolt, the SD5560T could look attractive.

The product data adds a warning, though. Kensington marks the SD5560T as out of stock and points buyers to a replacement SKU. That does not make the dock unusable, but it changes the buying logic. The SD5560T is a deal dock now. Buy it if the price is low, the return policy is good, and your exact laptop-monitor setup fits the limitations.

The SD5780T costs more, but the money buys features that age better: Thunderbolt 4, HDMI 2.1, 2.5GbE, two downstream Thunderbolt 4 ports, UHS-II SD, a longer cable, TAA compliance, and lock slots. It also has the higher product score. If the dock is for a desk you use every day, especially for paid work, those upgrades are worth more than the MSRP gap suggests.

Choose the Kensington SD5560T if

• You found it at a strong discount and can test it with your laptop and monitors.
• You need a driverless dock that can handle both Thunderbolt and USB-C Alt Mode laptops.
• One external display is enough when using USB-C-only hosts.
• Dual 4K@60Hz on Thunderbolt hosts covers your monitor setup.
• You want 96W charging and a three-year warranty without paying SD5780T money.
• You do not need 2.5GbE, a card reader, HDMI 2.1, or two downstream Thunderbolt 4 ports.

Choose the Kensington SD5780T if

• You want the better overall dock based on the product scores.
• Your main laptop has Thunderbolt 3, Thunderbolt 4, or USB4.
• You need 2.5 Gbps Ethernet for faster local network transfers.
• You use a 4K@120Hz display or may upgrade to one.
• You want two downstream Thunderbolt 4 ports for displays, storage, or accessories.
• You need a built-in UHS-II SD card reader.
• You are buying for an office where lock slots, TAA compliance, DockWorks, and a three-year warranty matter.

Verdict: SD5780T for most buyers, SD5560T for discounted hybrid desks

The Kensington SD5780T is the better dock for most buyers. It scores higher, uses Thunderbolt 4, has HDMI 2.1, supports faster Ethernet, includes an SD card reader, and gives you two downstream Thunderbolt 4 ports. It also has stronger display modes on supported hosts, including 4K@120Hz and dual 6K@60Hz configurations listed in the product data.

The Kensington SD5560T is the more situational pick. Its hybrid Thunderbolt 3 and USB-C Alt Mode design is useful when multiple laptops share a desk and not all of them have Thunderbolt. Its 96W charging and three-year warranty are still strong. Its limits are also clear: one HDMI display on USB-C hosts, no card reader, Gigabit Ethernet, and an older Thunderbolt 3 accessory path.

Buy the SD5780T if you want the safer long-term Kensington dock for a Thunderbolt laptop. Buy the SD5560T only when the price is low enough to make the older, simpler hybrid design worth the trade-offs.
