Anker 778 Dock Overview & Ergonomic Context

Most Thunderbolt 4 docks force workstation builders to buy extra USB-C-to-DisplayPort adapters just to connect two or three monitors. For financial analysts, software engineers, and multi-screen productivity users who want native video ports without DisplayLink software compression, the Anker 778 Thunderbolt 4 Docking Station (12-in-1, Model A83A9) stands out as one of the most capable single-cable hubs on Amazon USA.

Powered by an Intel Goshen Ridge Thunderbolt 4 controller paired with an integrated DisplayPort 1.4 Multi-Stream Transport (MST) hub, the Anker 778 offers four native video outputs—one HDMI 2.1, two DisplayPort 1.4, and one downstream 40Gbps Thunderbolt 4 port—while simultaneously feeding 100W of continuous power to your host laptop.

Video Matrix & Multi-Monitor Architecture

True Quad-4K Output for Windows Workstations

On a Windows 11 laptop equipped with a Thunderbolt 4 port supporting Display Stream Compression (DSC), the Anker 778 can drive four independent 4K@60Hz monitors over a single upstream cable. If you are running a single ultrawide or high-refresh monitor on an Ergotron HX Ultrawide Arm, the HDMI 2.1 port supports up to 8K@30Hz or 4K@120Hz.

Important macOS Display Note

Because Apple’s macOS does not support DisplayPort Multi-Stream Transport (MST) daisy-chaining for extended desktops, MacBook users connecting to the HDMI and DisplayPort jacks will see mirrored screens across the MST group. However, you can still achieve dual extended 4K@60Hz displays on Pro/Max MacBooks by connecting one monitor to the downstream Thunderbolt 4 port and the second monitor to either the HDMI or DisplayPort output. Mac users who prioritize 2.5GbE Ethernet and UHS-II SD card slots should also compare the CalDigit TS4.

Power Distribution: 180W Total Budget

Backed by a substantial 180W power supply, the Anker 778 never starves connected peripherals when your laptop is under full CPU/GPU load:

Upstream Host Port: Up to 100W PD (sustains 16-inch laptops and Dell Precision/XPS workstations at full performance).
Dual Front USB-C Ports: Both front-facing 10Gbps USB-C ports support 30W Power Delivery (45W combined)—fast enough to rapidly charge an iPad Pro, iPhone, or Logitech MX Vertical Mouse right from the front panel.

Frequently Asked Questions: Anker 778 Thunderbolt 4 Docking Station (12-in-1)

Key desk setup tips, fit details, and daily use advice.

Why can't my base M1, M2, or M3 MacBook run two outside monitors with a normal dock?

Base Apple M1, M2, and M3 chips only have one video output lane built into the chip. Standard docks pass raw video, so macOS can only mirror a second screen. To run two or three separate screens on a base MacBook, use a DisplayLink dock (like the Plugable UD-ULTC4K) and install the free DisplayLink Manager app.

How many watts of charging power does my laptop need from a dock?

Thin laptops (MacBook Air, Dell XPS 13) need 45W to 65W. Larger 14" to 16" work laptops (MacBook Pro 16", ThinkPad P-Series) pull 85W to 100W during heavy work. Picking a dock with 85W to 98W charging keeps your battery full all day.

Can I plug a Thunderbolt 4 dock into a regular USB-C laptop port?

Yes. Thunderbolt 4 docks work with standard USB-C and USB4 ports. Total speed and screen count will simply match what your laptop's USB-C port supports.

Does a USB-C dock add screen lag during daily office work?

Native Thunderbolt 4 docks (like the CalDigit TS4) send direct video signals with zero added lag. DisplayLink docks add less than one frame of delay, which you will never notice for coding, spreadsheets, or 4K video.
