Each display or Thunderbolt peripheral consumes its chosen output. A data-only USB-C socket cannot drive a monitor. Shared bandwidth and actual charging depend on the host and connected devices.

- TS4 dock
- 230W power supply
- AC power cord
- 0.8m Thunderbolt4 host cable
- Rubber feet strips
Display cables and video adapters are separate. The checker counts them as owned only when you confirm the required quantity and rating; otherwise their cost remains unknown.
230W is the power-supply rating; host delivery is at most 98W. These are different numbers.
EXACT HOSTS, QUALIFIED ANSWERS
Your computer sets the screen limit.
| Our checked host | Native display budget | Remaining conditions |
|---|---|---|
| MacBook Air M1 (2020) | One external native display total | macOS 11.4 or later; cable, power and exact timing checks still apply |
| MacBook Air 13-inch M4 (2025) | Two external native displays total | macOS 15 or later; the finder covers up to two 4K60 routes |
| Dell XPS 13 9315 laptop | Up to two checked native display routes | Windows 11 with suitable Thunderbolt/graphics drivers, and the required display cables |
Displays connected elsewhere use the same native display budget. No DisplayLink workaround is assumed. Other computer models and higher-resolution/high-refresh modes need separate evidence.
Know these limits.
- CalDigit explicitly states sustained98W host PD with its included supply.230W is the power brick, not laptop charging. Laptop negotiates the supported amount; demanding laptops may still need their own charger.
- CalDigit macOS eject/charging utilities are optional; Windows Ethernet driver may be needed for Ethernet. Do not label every dock function universally driver-free.
- Three physical video-capable outputs do not mean three independent monitors. Any monitor must use DP or a downstream Thunderbolt port, not a data-only USB-C port.
Protected streaming needs a verified monitor/cable/adapter/service chain. A native dock alone does not guarantee HDCP playback.
