Found a work around of sorts, but it is not ideal:
Problem: VGA monitor not displaying an image when plugged into a macbook air via mini-display port to VGA connector.
- Plug in mini display port & VGA cable
- Wait for computer to detect display
- Unplug the VGA cable but leave the mini display port adaptor plugged in to the computer
- Under settings > displays, click "detect displays"
- Wait for computer process the fact that the VGA monitor has been unplugged from the adapter (normally denoted by the macbook air screen flashing)
- Plug the VGA cable back into the adaptor
- Click "detect displays" again
- External VGA monitor comes to life
Unfortunately, on my computer I have to repeat these tedious steps every time I wake the **** thing up from sleep mode or the display goes to sleep automatically.
WHY APPLE?? Why does windows work better on your own hardware??
