Problem:
Your classroom display (or second monitor) is connected and powered on but it only displays the default home screen that is normally on the PC/Chromebook.
(If your second display is showing the image you usually see on your PC/Chromebook that is a good sign it is connected correctly.)
Cause:
Cause:
PC/Chromebook is set to show two different displays (extended) instead of duplicating the views (mirroring). The settings may have changed because you are connecting to an unfamiliar display or because you inadvertently pressed F8 (a possible shortcut to the settings).
In Mirror Mode your PC/Chromebook shows the same display on both screens. In Extended Mode your PC/Chromebook usually displays different images. If you don't have any software open then both screens may show the same background image as your PC/Chromebook. Test if your display is in Extend View by dragging the mouse, usually to the right. If your mouse cursor moves off your main screen and reappears on the other screen it is in Extended View. If your mouse cursor does not show up on the other screen it may be that you haven't found the correct passage to move your cursor over or that your cursor becomes so small on the second screen that it is difficult to find.
Fix:
Fix:
Switch to Mirror Mode (Directions #1) or use the Extended View (Directions #2).
Mirror Mode can be a little simpler to use but Extended View gives many advantages so it's worth trying.
Directions #1: (Switch to Mirror Mode)
Directions #1: (Switch to Mirror Mode)
Open the Settings Menu and navigate to the Display Settings
Chromebook: Startup Menu (circle icon at lower left) --> Settings (gear icon) --> Device (left menu) --> Displays
PC: Startup Menu (Windows icon at lower left) --> Settings (gear icon) --> System --> Display (top of left menu)
The appearance of the Display Menu changes as you adjust settings and when a second display is properly connected. In most cases you should see two rectangles. Below those is the setting to change the display modes.
Chromebook: Check the box next to 'Mirror Built-in Display and the changes should be instant.
PC: Look for a the heading 'Multiple displays'. In the menu box beneath that heading select the option to 'Duplicate these displays'. You will be shown the new screen layout and a screen will pop up for you to 'Keep these display settings?'. If you don't choose 'Keep Changes' in 10 seconds it will revert to the last setting.
You can close the Setting Menu. Your most recent setting should stay in memory for future times you connect to the same display.
Directions #2: (Using Extended View)
Directions #2: (Using Extended View)
Open the Settings Menu and navigate to the Display Settings
Chromebook: Startup Menu (circle icon at lower left) --> Settings (gear icon) --> Device (left menu) --> Displays
PC: Startup Menu (Windows icon at lower left) --> Settings (gear icon) --> System --> Display (top of left menu)
The appearance of the Display Menu changes as you adjust settings and when a second display is properly connected. In most cases you should see two rectangles which represent the two screens you have connected. Drag them around to adjust the direction and exact spot you need to move your mouse to access each screen. For example if one box is above the other you will have to move your mouse cursor up and down to transition between display screens. Notice if the boxes are off-set there may only be a small portion of the corner where you can pass from your PC/Chromebook screen to your second display.
Chromebook: Rearranging the rectangles has instant effects so you can test it out after each adjustment.
PC: You need to select 'Apply' after rearranging the rectangles in order to test it out.
Close the screen and the most recent setting will apply every time you connect to that second screen.
