In the case of computers Acer Aspire, the combination to send the screen view to a projector to external monitor is in the combination Fn + F5. It may happen that it does not respond, and when you have 200 people in front, it is a big problem.
Let's see how to solve it.
If everything is in order
One of the main causes, is that only the keys are pressed, the style that would be done with any other laptop and we have the impression that nothing happens. Either other keys are used, sometimes F5. Press the blue letters key Fn, then F5, but do not release the function key until the floating menu appears that allows you to choose which one you want to send:
- The first icon means that it does not send anything, so doing so by releasing the Fn key does nothing.
- The second, sends a second monitor, leaving the view also on the laptop. The disadvantage of this option is that you can not have higher resolution than that supported by the laptop.
- The third sends only to the external monitor. This is ideal, if you have an external monitor and you want to have higher resolutions not supported by the laptop.
- The room sends only one projector, at a resolution of 800 × 600
If something has been unconfigured.
Usually it happens that a naughty one has decomposed something, generally to have touched the msconfig To seek to improve boot speed.
For this, we do:
Start> run> msconfig> accept
Here we go to the Home tab, and verify the QtZgAcer option. Activate it, then select OK, The system will require a reboot.
Once the machine reboots then the problem should not exist again.
When we modify this, a message appears that reminds us that we have touched the boot configuration. We must activate the option that you do not remember it again.
Other strange causes will have to see if the projector is not connected to the proper port (some are brought) or that it is half obsolete and requires restarting to recognize the machine.
It also happens that the combination of the FN + F5 keys do not lift the tab to choose the shipment; It usually happens because the machine has been turned off and on after using a secondary monitor or when a third monitor such as the Ipad has been integrated with the Idisplay application. The output is to right-click on the desktop and choose properties, then in the "configuration" tab each monitor is selected and the option "desktop sharing" is deactivated, then accept.
