Can't extend display


Suddenly my PC/GPU has become unable to extend the display to a second monitor. I am using an Asus RX 580 and have been using a dual monitor set up for almost a year and it just randomly stopped working. I know that both monitors and cables are working, because I can freely switch between either monitor as long as only one is being used at a time. However, when I click extend display in the windows settings, it acts as if the display has been extended but then the drop down menu reverts to saying "show on only 1". I have included screenshots of this. I have already tried uninstalling and reinstalling graphics drivers, updating windows, and even did a system restore to no avail. I am not sure if this is a problem with the GPU or a windows issue. Any help would be appreciated. The two monitors are a Samsung Odyssey G5 running on HDMI and an older LG running on DVI.

Re: Can't extend display

Does Windows recognize both monitors at the top?

When you click on each monitor to identify does it?

Does Device Manager show any errors or yellow flags?
