The CalDigit Thunderbolt 4 Pro Dock is designed to provide extensive connectivity options, including support for high-resolution displays. When connected to an M4 MacBook Pro, the dock can support a single display up to 8K at 60Hz or dual displays up to 6K at 60Hz. However, the actual display capabilities may vary depending on the specific M4 chip model and the configuration used.
For the M4 Max chip, which is part of the newer MacBook Pro models, the support extends to up to four external displays when using multiple Thunderbolt docks, but this requires specific configurations and additional hardware. In a standard setup with a single dock, the M4 Max chip supports up to two displays at higher resolutions, such as dual 8K at 60Hz, depending on the available Thunderbolt ports and the use of adapters[2][3][6].
It's important to note that the display resolution and number of supported displays can be limited by the computer's GPU, operating system, and available ports. Therefore, it's advisable to check the specifications of your M4 MacBook Pro model for precise details on display support[3][6].
