I know nothing about this stuff, forgive the ignorance in the words I use to describe this.
I have a Dell All-In-One 2330 running Win10. I was attempting to set up a second monitor on it.
I had the second monitor hooked up, no problem. I did a right-click on the Tray Icon, and it showed me the ability to select different types of monitors. I chose one, and my primary screen went black. I unplugged the secondary, and my screen came back on.
I tried to Right Click the Tray Icon again and select a different type of monitor... except it's now showing a totally different context menu. Now I see Panel Fit, Hot Keys, etc. No options to change devices.
I've been through the control panel for the past hour...but I must be missing something, as I find no way to undo whatever I did.
Even after several reboots, and an uninstall of the Graphics Controller, I get a black screen on my primary as soon as I plug in the second monitor. The second monitor is also not working yet, but that's because I can't see the primary screen to actually configure it.
Does that make any sense?
Thank you in advance for any help.
