Using Docks at Higher Refresh Rates.

Using Docks at Higher Refresh Rates.

Last Modified: March 4, 2024

The display functions of our docking stations is one of the key features that many users look for. With that being said, different users have different needs when it comes to the refresh rates of their monitors. We’d like to make it clear that our docks are capable of higher refresh rates for those users who need it.

* Please keep in mind that the refresh rates and resolutions that are fully supported for each product are detailed on the product page for your CalDigit device. Higher refresh rates are possible in certain configurations, but results will vary based on individual setup, and all components including all connectors must support the increased capabilities.

Please use the below table to identify the refresh rate capability of our products with a monitor set to a resolution of 2560×1440 (1440P – QHD, WQHD) at 60Hz, 100Hz, 120Hz, 144Hz and 240Hz.

* Please note that left and right ports are designated based on how they are viewed from the front of the docking station. For instance, on the USB-C Pro Dock, the right DisplayPort is the one which is directly next to the USB-C host port labeled ‘Computer’.

** Your system including OS, GPU, drivers, cables and monitors must support above resolution and refresh rates.

*** Apple M1 / M2 / M3-based Macs including MacBook Pro 13″ and MacBook Air can only support ONE external display. First come first served. M1 Pro / Max / Ultra Macs can support dual monitors from a single Thunderbolt port. M3 MacBook Air can also support dual external monitors up to 5K and 6K when the laptop lid is closed (clamshell mode).

**** Some 4K/144Hz monitors do not have DSC (Display Stream Compression) feature turned on by default. You will need to enable DSC support from monitor’s OSD menu manually.
