Windows 10: I NEED MY MAIN DISPLAY TO BE #1!!!!!!!!!!!!!!!!!

I have a Dell monitor and a HDTV (720) connected to my Windows 10 computer.
Dell is horizontal - DVI
HDTV is vertical - HDMI
When I turn on the computer and monitor is ON, Windows sees it as Display 1. Unfortunately when I turn on the TV, Windows assigns #1 to TV!!!! Rather than monitor, which is really infuriating . Even though my monitor is set as the "Main Display" When I try to change to clone displays Windows takes orders from the HDTV and tries to switch view on My main display from horizontal to vertical instead of forcing the TV to display horizontally on vertical screen.
I know it might seem very odd, but I need this for my MAME dual screen setup. It used to work correctly on Windows 7 and even on Windows 10 , but at some point something got messed up.
On top of that MAME won't load correctly. All versions hang when launched. Also because of the wrong order MAME was showing settings screen on wrong monitor when launched. All because of the wrong order. And I know it's not MAME but Windows, because MAME works just fine when only one screen is turned on. HDTV is mounted vertically, but I want it to display horizontally on Vertical panel in cloned mode. Mame can display both screens that way. On the Horizontal I can have game displayed horizontally and then on the vertical it will clone the same display but horizontally. So clearly it can be done and handled, just POS Windows refuses to do it right.
What can I do? All I find is how to change the monitor I want to be the "Main Display" while I need the main display to be #1 not #2 and that I cannot change!


How does Windows allowing to take priority on 720 display!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!??????????????????????????!!!!!!!!!!!? It's absolutely ridiculous!

I have so many issues with displays and how Windows handles it it's not funny! Even my main computer I have 2 monitors, VR and HDTV connected and when I turn TV on it turns off VR and monitors for a moment and then jumbles applications and throws them all over the displays and of course COMPLETELY rearranges order of the displays. Again all of a sudden my #1 is no longer number 1!!!!!!!!!!!!!!!!!!!!!!!


FIX IT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

FIX IT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


I AM SO ANGRY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Hi Maheen,

Thank you for posting in Microsoft Community.

This issue could have occurred due to these reasons:

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.

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.

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.
