External Screen Issue

Nov 14, 2018
Hi All,

I've been having issues with my HP elitebook after connecting to 2 external screens (so 3 screens in total including the laptop screen) It usually sits in a doc with 2 cords running into the screens.

After removing it from the doc the other day, which I do regularly with no issue, my laptop will start normally displaying the HP logo and starting windows screen, however before it gets to the log in screen it goes black as if the log in page is being displayed on another/ external screen. If i move the mouse, the pointer will still run across the screen so I know the screen is not dead.

However when I connect it to my current doc (or another doc) it will not connect or register any external displays. If i connect an external screen directly to the laptop, it will recognize the second screen however both will fail to show the log in page. I have tried logging in blindly but to no avail. The doc, cords, and external screens work with other laptops so I know they aren't the issue.

I've tried using different docs/cords/monitors but to no avail. I have a feeling it is trying to display it on a different monitor however am unable to adjust any settings as I can even view the log in page.

Any help would be greatly appreciated!


Try these...

Option 1 ...

1. First, while the computer is off, connect an external monitor.
2. Next turn on the computer and allow it to fully load.
3. Once loaded, press the "Windows Key" + "P" to open the "Easy Display Switcher".
4. In here select "Computer only".
5. Now shut down the computer and disconnect the external monitor.
5. Disconnect the external monitor
6. And finally restart the computer.

Option 2 ...

Make sure you wait until the computer would be fully loaded before trying this, and not try it right away like you would to say get into BIOS. This needs you to actually be where you would be when Windows Explorer loads.

1. Press "Shift" repeatedly until the "sticky keys" window shows up.

2. Now click the the link there that will lead to the "Ease of Access Center".

3. Next click "Cancel" on the the bottom right corner of the "Set Up Sticky Keys" window.

4. From here you want to click "Control Panel" on the upper left corner (it should be right beside the "Make Your Computer Easier to Use" title.

5. Locate the "Computer Settings" menu and then choose the "Recovery" icon (make sure that your view of this is by either large or small icons for easier access).

6. Now click and open "System Restore".

7. Here you want to click next on the bottom right corner (a few times) until the button "Finish" shows up and then click it. (Just follow everything prompt that the window says which will lead you to recovering your previous system, in a certain time.

8. The computer will now do the work it needs to and then reboot.

If that doesn't work, you can try the following...

You can also try doing the Ctrl+Alt+Delete and see if you can get "Task Manager" to show.

If the "Task Manager" windows shows, then choose "New Task" and then type in EXPLORER. If the desktop shows up then you need to go into "Start", "Programs", then "Accessories" and finally "Command Prompt". (Or you can do a search for CMD.)

Make sure you load the "Command Prompt" with Administrator access. Then when it loads type in....


It will do a file check.
