Samsung DeX screen is not displayed on the monitor or TV. What should I do?
Cable connection to a monitor or TV
If the Samsung DeX screen is not displayed on the monitor or TV that is connected through a cable, please check the following:
1Check and make sure that an official Samsung DeX-supporting accessory is connected to your monitor or TV via an HDMI cable.
2Make sure that HDMI is selected as the input for the monitor or TV. (Please change the input of the monitor/TV to HDMI).
3If the screen displayed on the monitor/TV is a mirror of the device's screen and not the Samsung DeX screen, open the notification panel on the mobile device by swiping down from the top of the screen and select DeX in the Quick Settings menu.
Note: If you wish to have Samsung DeX launched every time a monitor or TV is connected, go to “Advanced features” > “Samsung DeX” in the tablet's settings, and then enable “Auto start when HDMI is connected”.
4Check whether your device is in maximum power saving mode, Safe mode, Emergency mode, or Kids mode. If your device is in any of those modes, turn off the mode via Settings before connecting.
5If there's water in the smartphone or tablet's port, the screen may not be displayed on the monitor or TV correctly.
Wireless connection to a TV
1For Samsung TVs released in 2013, please update the firmware and try to connect again.
2If the connection fails after displaying “Connecting…” for a while, please retry after disconnecting and reconnecting the power cable of the TV or dongle.
3If the above suggestions do not help resolve the issue, we’ll need to analyze the log. Please forward the issue to us by going to [Samsung Members App > “Contact us”/”Report error” > “Report error” and marking the “Send system log data” check box.
