Frequently Asked Questions
Can I use the TS4 with USB-C only laptops?
No, the TS4 requires Thunderbolt 4 specifically. It won’t work with standard USB-C laptops. The Anker 777 is the better choice for universal USB-C compatibility.
How many displays can each dock support?
CalDigit TS4: Up to 6 displays with daisy-chaining (requires TB4 monitors). Anker 777: Up to 3 displays (2x DisplayPort + 1x HDMI). For triple-monitor setups, the Anker 777 is more practical.
Is the file transfer speed difference noticeable?
Only if you transfer large files constantly. For typical workflows, the 10 Gbps USB-C connection is plenty fast. Actual transfer speeds depend on your SSD, not the dock bandwidth.
Which dock is better for gaming?
The Anker 777 is the gaming choice — it works with more laptops and has more USB ports for peripherals. CalDigit TS4 is overkill for gaming and requires TB4 support.

How we verify this guide
We cross-reference compatibility figures against manufacturer specifications where available, official service manuals, and the standards that govern fit — memory type and speed (DDR4 / DDR5 / LPDDR5), maximum supported capacity and slot count, SSD form factor and interface (M.2 2280, NVMe PCIe vs SATA, keying), and charger wattage and connector (USB-C Power Delivery, GaN). We’re explicit about soldered or non-upgradeable parts, prioritise primary sources over retailer listings, and re-verify the data on a regular cycle. More on our method →
