To connect the monitor to your MacBook Air M4 and utilise the full 5K resolution (5120 x 2880 pixels) without losses, you should use a USB-C cable that supports DisplayPort Alternate Mode (DP Alt Mode) and at least USB 3.2 Gen 2. The cable must be designed for 5K/60 Hz so that the signal is transmitted without loss. A standard USB-C charging cable is usually not sufficient for this, as it often only transmits power and data, but not a high-resolution video signal.

The monitor has a USB-C port that allows you to transfer image, power (up to 90 W) and USB data (for the integrated hub) with just one cable. Make sure that the cable offers the necessary bandwidth for 5K/60 Hz - if in doubt, a high-quality, certified Thunderbolt or DisplayPort cable will help.

A suitable docking station is not absolutely necessary, as the monitor itself acts as a hub and has USB-A and another USB-C port. If you still want to use a docking station, it must explicitly support 5K/60 Hz via USB-C with DP Alt Mode.

To summarise: Use a high-quality USB-C cable with DP Alt Mode and sufficient bandwidth for 5K/60 Hz, then you will get the full picture without losses - everything else (power, USB hub) runs directly via the monitor. If you are unsure, take a look at the cable specifications or contact the manufacturer's support.
