* 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.

** Your system including OS, GPU, drivers, cables and monitors must support above resolution and refresh rates.
*** Apple M1-based and M2-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.
**** 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.
