Windows 10: 2nd Display suddenly not showing

I woke my computer up from sleep mode and suddenly the second screen is not showing. It is detected, but not showing anything on the screen. I Shut Down and restarted. The computer shows the boot image on the second screen, but at the login screen there is no display. I've tried changing out the hdmi cord, using CTRL+Windows+Shift+B, disabled fast boot, Rolling back the drivers, updating the drivers, uninstalling and reinstalling the drivers, but nothing seems to work.


The display works since I can see the HP logo when booting up, but then nothing. I'm on a Windows 10 computer. Any help would be sincerely appreciated.

Windows 10 only displays Taskbar and Wallpaper on 2nd screen

Windows 10 has suddenly stopped incorrectly displaying the mirrored image on my 2nd screen - the only sections of the display that are being mirrored are the Taskbar and Wallpaper, regardless of what is being displayed.

This happens regardless of how the 2nd monitor is connected (HDMI cable or Wireless), or the Multiple Display setting chosen (Duplicate, Extend, or Show only on 2).

 

2nd Monitor suddenly not working

Hi,

Suddenly my 2nd monitor is not working. It is showing a message that it is not receiving any input from my computer. It was working fine until a few days ago. When I write-click on the screen to get screen displays, I am no longer given the option
to choose "extend". The options shown seem to indicate the computer thinks there is only one monitor. My computer just had a windows update, I believe. Any ideas?

4870x2 won't display at 1680x1050 at all!

OK. Now I know what ur problem is. Step by step:
1. Go to Catalyst Control Center
2. Click on the word "Graphic" right on top left corner. It will display drop down menu
3. Click on Display monitor and will see the list of monitor at near bottom
4. Right Click the monitor and select "Configure". It will show up the window
5. There will be 3 option to select. Select the middle one and then click on the tab which show the bar with 15%.
6. Drag the bar to max, and the screen will stretch to the native resolution 1680x1050.
7. Also click the tab with showing RGB drop down list and select the last one (it will change to image quality for pc).
That's it. Good Luck.
