What Are the Display Output Capabilities for the TBT-UDH2?
The TBT-UDH2 docking station provides video output via its dual HDMI 2.1 ports and a downstream Thunderbolt 5 port. The exact display capabilities and resolutions depend entirely on the host system's specifications, ranging from single 4K support on older systems to dual 8K support on newer Thunderbolt 5 systems. Thunderbolt 3 and USB-C only systems are not supported.
How Display Capabilities Vary by Host System
Multiple display capabilities for Thunderbolt 5 systems:
- Dual 8K 60Hz Displays on Thunderbolt 5 Macs - Connect up to 2x 8K 60Hz on M4 Pro/Max Macs with Thunderbolt 5 running macOS 26
- Dual 8K Display on Thunderbolt 5 Windows PCs - Connect up to 2x 8K 60Hz or 2x 4K 144Hz on Thunderbolt 5 Windows systems
Multiple display capabilities for Thunderbolt 4/USB4 systems:
- Dual 4K 120Hz Displays on Thunderbolt 4 Macs - Connect up to 2x 4K 120Hz, or 1x 6K 60Hz + 1x 4K 60Hz on Macs running macOS 26 with any base M4 or M5 chip, M1/M2/M3 Pro/Max chips, and base M3 chip with lid closed (clamshell mode)
- Single 4K 120Hz Display on base M1/M2 Macs - Connect up to a single 4K 120Hz or 1x 6K 60Hz display on base M1 or M2 Macs running macOS 26
- Dual 4K Display on Thunderbolt 4 or USB4 Windows PCs (Intel 12th Gen and newer) - Connect up to 2x 4K 120Hz on Thunderbolt 4 or USB4 Windows systems
Important Notes:
- The maximum resolution and refresh rate supported on the downstream Thunderbolt port will vary based on the connected USB Type-C video adapter, the host system, and the total number of connected displays.
- A maximum of two displays can be used at a time, configured as either two HDMI connections or one HDMI and one Thunderbolt/USB-C Alternate Mode connection.
