Apple MacBook 

CONNECTING TO A VIDEO PROJECTOR 
Once you have connected your MacBook/MacBook Pro to the installed rack equipment and turned the laptop on, the next step is to activate the connection to the video projector so that your presentation can be displayed. Please consult the rack instructions in the classroom for more information.
Once the LAPTOP input has been selected, the image on your laptop screen should be visible on the in-room projector or flat panel monitor. (Please note that in some classrooms, it may take up to an additional 5 seconds before an image appears.)
On occasion, additional steps may be required for an image to be displayed from your laptop. If an image doesn’t project and you see a black or blue screen or the projector says “No Input”:
Disconnect the Mac Adapter from your laptop, wait 5 seconds, then reconnect the Mac Adapter. This can help with signal syncing between the laptop, the installed rack equipment, and the projector.
Make sure that the VGA cable has a solid connection to the Mac Adapter.
Make sure that the VGA cable has a solid connection to the VGA port on the installed rack equipment.
If you have done the above steps, but an image still doesn’t show:
1. Click the Apple icon in the top-left corner of the screen.
2. Select “System Preferences”.
3. Click on “Displays”
4. In the lower-right corner of the new window, click “Detect Displays”.
If you are getting an image but it is different than your laptop screen you may have to enable “Mirror Display” on your Mac laptop.
1. Click the Apple icon in the top-left corner of the screen.
2. Select “System Preferences”.
3. Click on “Displays”
4. In the lower-left corner of the new window, select “Show displays in menu bar”.
5. Go back to the toolbar at the top of the screen - only this time, look to the right side of the toolbar. You should now see a monitor image like the one below:
6. Left-click and select “Turn On Mirroring”.
7. The same image should now be displayed on both screens.
Troubleshooting
The quality of the projected image resolution is poor/hard to read/ looks “squished”.
1. Ensure that “Turn On Mirroring” is checked. (In older Mac OS’s, there is an option box titled “Mirror Displays” under the “Arrangement” tab.) Refer to the section, “Connecting
to a video projector” for more instructions.
2. Select the “Monitor” tab /pane, and change the monitor resolution size to 1024 x 768, 60hz. Higher resolutions can be selected, but this is a standard resolution size which should resolve any resolution issues.
The projected image jumps around/flickers/shows static/has interference.
Make sure that the selected resolution size, whatever it may be, also uses the 60hz option.
The projected image is different than my desktop on my laptop screen.
Make sure that “Turn On Mirroring” (or “Mirror Displays” on older Mac OS’s) is selected.
This ensures that an exact copy of the main desktop will be projected. Refer to the section,
Connecting to a video projector” for more instructions.
Can see my presentation, but do not hear any audio outside of my laptop.
1. Make sure that the audio jack - which comes with the installed VGA cable in the classrooms - is plugged into the headphone port of your laptop. In rooms where the VGA connection is visible, check that the audio cable is plugged into its appropriate port on the rack.
2. Ensure that the main laptop volume is turned up and unmuted. Also, confirm that there is no volume slider within the application that you are using. If there is, increase the volume and ensure that volume within the application is unmuted.
3. Turn up the volume control on the Touch screen/switcher/panel installed in the room.
Connecting to the NYU Wireless Network:
To connect to the NYU Wireless Network with any personal Mac Laptop:
1. Click on the icon, located at the top right corner of your screen.
When clicked, you will see the grayed out message below, when the AirPort is active. In the pull-down menu that appears, make sure that AirPort is turned on. (If it is not on, select “Turn AirPort (or Wi-Fi) On”.)
2. Select “nyu” from the drop-down menu.
3. Enter your NetID in the “Username” field and your password in the “Password” field. Then select “Join”.
