The Galaxy Tab S10 Ultra supports the connection to a large screen via USB-C to HDMI, but not directly via a simple HDMI to USB-C cable.

- You will need a USB-C to HDMI adapter to connect your tablet to an HDMI-enabled display such as a TV or monitor[5|.
- Connect the HDMI adapter to the USB-C port of your tablet and the other end of the HDMI cable to the HDMI port of the display.

A simple HDMI to USB-C cable will not work for reverse transfer as these cables usually have unidirectional active circuitry.

Can I also connect a wired or wireless mouse to the external screen?
