How to change HDMI mode on Samsung devices

Samsung’s flagship smartphone since Samsung Galaxy S8 support Samsung DeX. This feature allows users to plug their phone into a monitor and even on Windows and Mac to use their phone as a desktop computer. Although, if you don’t want to use DeX when connected via HDMI, you can change the default HDMI mode on Samsung devices. There are only two HDMI modes โ€“ Samsung DeX and screen projection. Therefore, you can switch it to screen projection to mirror your phone’s screen only when connected to an external display via HDMI.

In this guide, we will show you how to change the HDMI mode on your Samsung device. Keep in mind that this setting is only available on select Samsung devices. Therefore, if your Samsung phone does not support DeX, the option will not be available to you. Keep in mind that if you switch HDMI mode to Screen mirroring, DeX will not launch automatically when you plug in a monitor via HDMI.
