Question
Why wont my Mac laptop display when connected via HDMI in my classroom?
Answer
Some classroom projectors have a maximum resolution of 1280x720 that new Apple Laptops do not detect properly. To fix this issue:
- Select the Apple icon in the top right and select System Settings.
- On the list on the left, locate and select Displays.
- At the top, select the monitor-shaped icon labeled with the word Extron.
- Toggle the icon next to Show all resolutions.
- Select the resolution listed as 1280 x 720.
