Windows 7 two screen extended

[1] is laptop screen
[2] big screen
[?] is screen added to the screen resolution interface. Was added by mistake.

After a cold reboot When I again select desktop/right-click/screen resolution the interface opens in [?] which doesn't exist so I cannot see it to delete [?]. My start button and task bar is in screen [1]. I can see that screen resolution icon is in the task bar but there is no way for me to view this screen.

Question: How can I reset my screen resolution interface setting possibly via control panel (no that I have no way of seeing and working with screen resolution interface)?

Remove the external screen and just use the laptop screen. Now can you reset the screen?

Go to Personalize (right click on Desktop), Display, Change Display Settings.  Can you fix the displays here?

Hi John,

Once I disconnected all external items and restarted. Another time I cold-rebooted. Both personalize, screen resolution, or control panel open in [?] screen.

Here I suppose I need to learn how to work with my computer without control panel from this point on unless someone knows a trick.

Same thin, cold start, open Screen Resolution and then click on Advanced Settings. That opens the Control Panel windows for display properties.

The only way for me to see Screen Resolution is to open in safe mode. Safe mode also allows me to see the control panel,

Now, after screen resolution I have the following tabs:
- Addapter (has Properties button)
- Monito
- Troubleshoot
- Color Management

When I click on Properties , VgaSave Properties opens up with the following tabs:
- General
- Driver
- Details
- Resources

What do you want me to do with Properties?
JohnBusiness Consultant (Owner)Commented:
The only two screens you can work with are Screen Resolution and the Control Panel Screen. Where did you set up the phantom monitor and how did you do it?

In Screen Resolution, there is Display Identification at the top. Is the phantom monitor there?
JohnBusiness Consultant (Owner)Commented:
In Registry, HKLM\System\ControlSet001\Enum\Display. Is the Phantom Display there?

Also look in just ControlSet.   ControlSet is the main area.

I have NO IDEA what will happen if you delete the phantom key because I have never made this error.
Mike EghtebasDatabase and Application DeveloperAuthor Commented:
I do not recall how I ended up with a phantom screen originally.

With safe mode I see only screen [1] not [2] or [?]. FIYI, the Personalize option on desktop right-click is not available with safe mode.
JohnBusiness Consultant (Owner)Commented:
Try running System File Checker to see if you can eliminate it.

Open cmd.exe with Run as Administrator and run SFC /SCANNOW. Allow to complete, shut down, start up and test.
JohnBusiness Consultant (Owner)Commented:
With safe mode I see only screen [1] not [2]  <-- I asked you to disconnect the other screen. How is it showing up.

Disconnect everything from this laptop, shut it down (all the way), start it up and then work through some of the suggestions I left. [2] should not show up.
Mike EghtebasDatabase and Application DeveloperAuthor Commented:
I never have worked with registries before. I guess I need to:
1. Locate where the registery is. (how?  Registry, HKLM\System\ControlSet001\Enum\Display?)
2. Make backup of it in case (what is the best way to do this?)
3. Locate lines has to be removed (how?)
4. Comment them out (how?)
5. Save and restart I guess.

Do you want me post separate  question for each?

Sorry I just saw your two recent posts
JohnBusiness Consultant (Owner)Commented:
To get to the registry, Start and enter regedit in the box. It should open. You can make a backup in regedit.
JohnBusiness Consultant (Owner)Commented:
No need to open a new question . Stay with this one.
Mike EghtebasDatabase and Application DeveloperAuthor Commented:
Good news. I restarted my computer to get out of safe mode to try your steps. Before which I tried to access screen resolution again and it displayed it with no problem. This is how it looks like:ScreenResolution
JohnBusiness Consultant (Owner)Commented:
Can you now delete screen 3 from this spot in the multiple display pull down?  or try Advanced settings again?

Now, what I want to accomplish:
1. Have only two monitors (get rid of [3])
2. Have larger screen with taskbar (extended view)

I hope not to mess up this time around.
Mike EghtebasDatabase and Application DeveloperAuthor Commented:
Now I got 4 monitors. Not sure how to delete them:ScreenResolution2
Mike EghtebasDatabase and Application DeveloperAuthor Commented:
I guess they will disappear automatically.
JohnBusiness Consultant (Owner)Commented:
From the Multiple Displays drop down menu select Disconnect this display. That should remove the display. Make sure no displays are connected at all (just the laptop display).

Hi John,

I figured out another easy solution I like to share with you.

Using alt+tab I am able to send focus to the hidden (Screen Resolution) then I hold window button and use left, right arrow keys to move this hidden window in the virtual (hidden) screen to other visible screens.

windows key + p also is one way
