How to Decide
CalDigit TS4 is a Thunderbolt 4 docking station prized by professionals and gamers for its 18‑port connectivity and up to 98 W laptop charging. The alternatives split into a few clear camps: Belkin Connect Thunderbolt 4 Dock leans into expansive multi‑display support with up to three 4K screens; Dell UltraSharp U4025QW is an all‑in‑one 40‑inch curved 5K2K monitor that bundles a Thunderbolt 4 dock into the display; Plugable UD‑6950PDZ emphasizes high‑wattage power delivery at 100 W and triple 4K output via a USB‑C‑centric dock.
When comparing these options, focus on (1) display capability – how many monitors and at what resolution each solution can drive; (2) power delivery – the wattage available to charge a laptop on‑the‑go; (3) form factor – whether you need a standalone dock or prefer an integrated monitor‑dock combo; (4) connectivity mix – the balance of Thunderbolt 4, USB‑C, HDMI, DisplayPort and Ethernet ports; and (5) price tier – the one‑time cost ranging from sub‑$300 docks to premium all‑in‑one monitors. These factors directly reflect the real differences among CalDigit, Belkin, Dell and Plugable.
