Why won’t my projector display video images from my notebook?
| If you want to use a notebook with video output, whether to display directly from a DVD or run a video clip within a PowerPoint presentation, you first have to switch off the notebook’s internal LCD MONITOR via the Fn + F3..F10 keys, so that only the external monitor is active.
However, you have to do this before starting the presentation as otherwise your notebook may crash.
Please also refer to Question 19, ‘Why won’t my projector display computer images from my notebook?’
When using Notebooks the external monitor output on the notebook’s VGA connector must first be activated.
Depending on the notebook this is done using the key combination: Fn plus F3..F10. (if necessary check this in your notebook’s manual).
These special function keys are colour-coded on your notebook keyboard (yellow, blue).
The Fn key is located between the Ctrl and Windows/Alt keys in the bottom left-hand corner of your notebook keyboard.
The monitor output function key is usually indicated with an LCD/CRT symbol or lettering on the F3..F10 keys.
Now press Fn + F3..F10 button to access the following:
Option 1: switches on both the internal LCD monitor and the external monitor output;
pressing again accesses
Option 2: switches off the internal LCD MONITOR leaving only the external monitor on. This is recommended since the notebook’s graphic chip will now transmit correct VESA timing to the beamer;
pressing again accesses:
Option 3 (standard): the external monitor output is deactivated, leaving only the internal LCD monitor active.
