I recently installed Debian 10 and it detects my second monitor, and when I enable dual monitors it turns on, but there is nothing displayed on it. Just a blank black screen.
There was one instance a couple day's ago where I left it connected and in dual monitor mode for a few hours and it finally started getting a video feed after a while, but I haven't been able to get it to do it since, and it came on rather randomly while I was across the room.
Any help here would be greatly appreciated.
The output of xrandr is
