Windows 10: unchecking make this my main display

hello, I have 2 monitors ( 2nd one just set up), I noticed today that when I tried to open something on my main screen (1st one) it was opened on 2nd monitor, (note: it was not turned on). so I started trying to configure them so the screen that I wanted as main, would be main. I checked the make this my main box.... only to realize that it was on the 2nd monitor. I cannot change it, (won't uncheck) is there a way to do this? or am I stuck with this configuration?

Display driver not supporting and device manager not showing Display adapter option

Hi Maheen,

Thank you for posting in Microsoft Community.

This issue could have occurred due to these reasons:

• Incorrect settings.
• Corrupt or outdated display driver.

Try the steps listed here and check if it helps:

Method 1:

I suggest you to download and install all the available Windows Updates including Optional Updates. Check if it helps.

Method 2:

If the issue persists, i suggest you to uninstall and re-install latest display driver from the computer manufacturer website and check if it helps.

Step 1: Uninstall display driver.

• Right-click on the Start Button and click on
  Device manager.
• Double-click on Display Adapters to expand.
• Right-click on the display adapter driver that is listed and select properties.
• In the window opened, click on drivers tab.
• In the drivers tab, Click on Uninstall option.

Now restart your computer and check, if the problem persists try step 2.

Step 2:

Re-install display driver from the manufacturer website.

Let us know if the issue is resolved or if you need further assistance, we will be glad to help.

I'm ready to act following suggestions (if any) before...going through the restore (please don't misunderstand, I'm not looking forward doing it).

I appreciate in any case your help

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.
