You can connect your Samsung Galaxy S23 Ultra to your monitor using a USB-C to HDMI adapter or cable that supports DisplayPort Alternate Mode (Alt Mode), primarily utilizing Samsung DeX.
Connecting your Samsung Galaxy S23 Ultra to a monitor can transform your phone into a desktop-like computer experience or simply mirror your phone's screen. This is made possible by the phone's USB-C port which supports video output.
Requirements for Connecting Your S23 Ultra to a Monitor
To establish a connection, you will need:
- Samsung Galaxy S23 Ultra: Your phone.
- Monitor: A monitor with an HDMI input is standard.
- Connecting Cable/Adapter:
- A USB-C to HDMI adapter and a standard HDMI cable.
- OR a USB-C to HDMI cable that directly connects the phone's USB-C port to the monitor's HDMI port. Ensure the cable/adapter supports DisplayPort Alternate Mode for video output.
Steps to Connect Your S23 Ultra to a Monitor
Connecting your phone is a straightforward process:
- Connect the HDMI cable to your monitor's HDMI input.
- Connect the other end of the HDMI cable to your USB-C to HDMI adapter (if using one).
- Plug the USB-C end of the adapter or the USB-C to HDMI cable directly into the USB-C port on the bottom of your Galaxy S23 Ultra.
- Your phone should detect the external display and prompt you to start Samsung DeX or Screen Mirroring.
Understanding Samsung DeX and Screen Mirroring
When connected, you typically have two main options:
- Samsung DeX: This mode provides a desktop-like interface on your monitor, allowing you to use apps in resizable windows, manage files, and multitask using your phone as a touchpad or connecting a keyboard and mouse. Your phone's screen can remain independent, allowing you to use it for other tasks or as a touchpad.
- Screen Mirroring: This mode duplicates your phone's screen onto the monitor. Whatever you see and do on your phone's screen will be displayed on the monitor.
Using Your Phone's Orientation
When using screen mirroring, rotating your phone can affect the display on the monitor. As seen in related content, if you turn the phone around into a landscape orientation like this, "everything on the screen" adjusts. This is particularly useful for viewing videos, photos, or playing games on the larger monitor display in a wider format when mirroring. In Samsung DeX mode, rotating the phone often switches it between acting as a touchpad or mirroring a simplified interface to the phone screen itself while the monitor shows the DeX environment.
