    No, the USB-C ports at the back of the LG UltraFine 5K are for data only. They cannot carry video.

    The Thunderbolt connection of the LG UltraFine 5K to the MBP can carry only two DisplayPort signals anyway and both DisplayPort signals are used by the LG UltraFine 5K (one signal for the left side of the display, and another for the right side of the display) to obtain a 5K 60 Hz resolution.

    There exist USB to DisplayPort adapters. Research DisplayLink adapters for more information. They do not perform like a graphics card. They are not good for video playback or gaming. They might not work as well in macOS as they do in Windows.
