Have been using RX5700 XT for months, Windows 10, Adrenalin 19.11.2, 3 identical Samsung LED monitors, switching in and out of Eyefinity. Upgraded to 20.2.2, working fine, switched on Eyefinity, only 2 monitors working, switched off Eyefinity, still only 2 monitors, reboot, all 3 back on line. Tried again, same thing, this time after re-boot, the 2 monitors connected to Displayport no longer recognized at all. Have done DDU clean uninstall, and have tried again with all versions of software, 19.11.2,020.2.2,20.4.2, still no recognition of monitors connected to Displayport. Also, eyefinity tab no longer even appears on ANY of the 3 versions of Adrenalin BTW, Re-live NOT installed, so no Remote Play enabled All 3 monitors work fine connected to HDMI output. Factory reset monitors, nothing. When the only monitor is connected to Displayport, the BIOS-motherboard startup screen appears, but goes black when Windows loads. VR headset works fine on Displayport output.

Laptop suddenly stopped recognizing the external monitor

Hi,

Thank you for posting your query in Microsoft Community.

To assist you better, I would like to ask if the laptop is unable to recognize only the external monitor or other external devices also.

I suggest you to run the Hardware and Devices troubleshooter by following the steps below:

• Click on the Start button, and type “Troubleshooting” on the search bar.
• Click on “Hardware and Devices”.
• A pop-up will appear, click on the “Next” button and your hardware troubleshooting will start.
  

Hope the information is helpful. Keep us posted on the status for further assistance.
