You can connect the two Samsung LS24C310EAUXEN monitors to the HP USB-C Dock G5 with HDMI cables, but there are some restrictions to consider:

- The dock has one HDMI 2.0 port and two DisplayPort™ ports.
- You can use both monitors at the same time by connecting one of the monitors via the HDMI port and the other via one of the DisplayPort™ ports. However, you will need a DisplayPort™ to HDMI adapter if your monitors only have HDMI inputs.
- It is not possible to connect both monitors directly to the dock via HDMI at the same time, as only one HDMI port is available.

So you either need to buy a DisplayPort™ to HDMI adapter or make sure that one of your monitors has a DisplayPort™ input. Another docking station is not necessary in this case.
