After testing out the Secretlab Magnus Pro over several weeks, I can say it's a fantastic desk with a few small flaws.

Astralogic make a bi-directional DP to USB C cable, so you can go from DP out on your PC to USB C (DP Aux) on the monitor. This sort of cable is rarer than hens teeth for some weird reason.

If its capable, ensure you have all the cables to connect the monitors. Next, hook up all the cables to the monitors and your PC using HDMI or Display Port. This depends on what ports your PC has.
