CalDigit TS4

Start with your screen cables

There is a full-size DisplayPort connection and two downstream Thunderbolt 4 ports. HDMI monitors require an appropriate adapter; there is no native HDMI socket. The documented dual-display configurations depend on the host, with additional DSC and DisplayPort requirements above 4K60.

One feature has a less obvious host requirement

The 2.5Gbps Ethernet connection requires a Thunderbolt host or a USB4 host supporting PCIe. A basic USB-C computer does not gain every feature just because it connects. Check this before choosing the TS4 primarily to replace a network adapter.

Consider the whole desk instead of the port total

The 98W charging specification, SD and microSD UHS-II readers, and front/rear audio options make this a candidate for a permanent workstation. A person using only a keyboard and one HDMI screen may get little value from the extra infrastructure. Conversely, someone frequently swapping drives and cards should map where those devices will connect and reserve the downstream Thunderbolt ports for peripherals that need them.

These are published specifications, not results from hands-on testing. Maximum screen counts depend on the laptop, operating system, connection and chosen resolution.
