Display and multiple monitor issues:

Common Display Issues: 

Monitor appears disconnected

• Confirm the power button is "on" for both the PC and the monitor- you will see the power "on" light generally white or blue.  If the monitor is off the light will generally be amber or not lit.
• Unplug the cord from Monitor to PC and re-connect to confirm a secure connection
• Attach the monitor to a different computer or laptop.  If the monitor still does not work, enter a help desk ticket.

Cannot see the computer login screen

• On the keyboard hold Ctrl+Alt then tap Delete key - choose the Sign In option.  The display may be power saving. 
• Check that other display devices are turned on (projector, another monitor) for login screen

Mouse appears, but everything else is black

• Check that all other display devices are turned on (projector, another monitor), if previously you were on the other monitor the window you were working with may still be displaying on the other monitor viewing screen.

Cannot calibrate SMART board

• See this article section relating to SmartBoards

Typical Cause:

• Rather than using separate VGA splitters that would send the same display signal to two sources (monitor and projector), many of the new computers now have multiple ports/hookups that allow us to directly plug the monitor(s)/projector into individual ports.
• Windows will now treat your projector like a second monitor.
• Because of this, Windows will initially believe that you have two monitors set up and that you want your "desktop" to display/extend over both screens.

Steps to Resolve the Issue:

1. First, turn on the projector and see if the login screen appears. If so, log in and proceed to step 3.
2. Try disconnecting the cable that goes to the projector from where it is directly plugged into the PC.
   1. If you can now see the correct screen, log in and proceed to step 3.
3. Change the display settings:
   1. Right click anywhere on the desktop - a context menu should appear.
   2. Click on the "Display settings" option - a new window should appear.
   3. If the option is available, check the "Make this my main display" option.
      
   4. If it is not available, you may need to select another display (Click the box labeled 2, etc) and/or reconnect the projector cable.
   5. 
      

If you prefer, while in the "Display settings" window, you can change the option under "Multiple Displays" from "Extend these displays" to "Duplicate these displays"   

6. After doing so, you will need to select "Keep these settings" to avoid Windows reverting back to the original settings.  You may also need to change the resolution back to the biggest resolution for things to show normally. 

If all of the above steps still do not resolve the issue, please submit a ticket to the Help Desk to investigate the issue further.
