Projector display aspect ratio and/or color issues

If you find that a classroom projector is displaying, but the aspect ratio is smaller than it should be, and/or the display has a off-colored hue to it, the display settings need changed. 

Using the classroom projector remote, navigate to:

Mac OS:

1. Screen Mirroring -> Display Settings -> Refresh rate ->
2. Select 30Hz

NOTE: This issue has only been observed in a room with an Apple (MacOS) computer.  However, if a Windows (PC) experiences a similar problem, these instructions may also be followed

Windows:

1. Display Settings -> Advanced Display -> Choose a refresh rate ->
2. Select 30Hz (options may vary but any option lower than the current setting will have the same effect) 

If problems continue with the projector display, click the 'Get IT Help Now" button, on the right.
