Windows 10: Screen duplication, freezing, and black screen with full power fans on dual monitors windows 10

Hello,I have been fighting this for some time now. I have a dual monitor windows 10 setup. When I start my computer, it is common for both monitors to display the exact same thing, mouse and all. When I go into settings, windows fails to even detect a second monitor. Screen projecting is also set to off. When looking at the monitor's hz setting, it reads 1. I have started my computer by alternating which monitor I have plugged in, and they both register as 1 hz. My computer will often freeze up and become unresponsive. I tried the command where you make windows play a sound to no avail. I have

Hi Coltswrestling,

Thank you for writing to Microsoft Community Forums.

1. What is the make and model of the computer?
   
2. Have you tried connecting
   using different cables?

You may try the below suggested steps to fix the issue.

Method 1: Change screen resolution on PC

1. Go to your desktop, right-click your mouse and go to
   Display Settings.
   
2. On the settings Window, click on “Advanced display settings”.
   
3. From the drop down menu, select the “Recommended” resolution and check the status of the issue.

Sometimes this issue might occur possible due to faulty drivers. It is required to update the necessary display drivers to fix the issue. Please refer the article

Black Screen solveed definitively

I have this same issue. Windows 10 was installed and was working fine on my laptop and then one day, black screen without a cursor or anything. I can only power the unit off and on, but with nothing other than a black screen I can't do anything. Tried the "ctrl-password" step but nothing. Nothing on the keyboard has any effect, I can only do a hard power off/on.

The only thing I can think of, all had been working fine when my battery died. My laptop automatically shut down and went to blank (not black) screen. I plugged it in for a while to charge but ever since then, I can power on, I hear the harddrive spin and the fan comes on, but I never get anything other than a black screen. Did your problem start after a power issue?

 

Uninstalling a duplicate screen

Hi Ronald,

Thank you for writing to Microsoft Community Forums.

I understand that you want to stop duplication of the screen.

1. When you say “stop the duplicating” do you want to extend the screen or do you want to keep only the PC screen?
   
2. What is the version of Windows that you are using currently?
   

Refer to the article to check
Which version of Windows operating system am I running?

You can choose how you want the desktop to display. You can press the Windows logo key +
P and select an option.

Types of Display Modes in Windows 10 for settings up dual monitors:

• PC screen only - The second screen is ignored and only the main display is used.
• Duplicate - The main display is mirrored on the second screen.
• Extend - The main display is extended across the two screens and allows you to have a desktop that spans two screens or to use Metro on one screen and the desktop on the other.
• Second screen only - The main display will be disabled and only the second screen is used as your new main display.
