Having problems with your Acer Aspire 5720 Notebook ?

Connection to external monitor stopped working

\015 I used to work on an external monitor (HP 1740) with my Dell Latitude 620. Suddenly the connection does not work any more. With FN - F8, the internal monitors switches off, however the external does not receive the signal. Using the basic diagnostic tool did not show me any hardware problems and my laptop actually detects the external monitor. What can I do?\015

Answers :

Did you go to the display properties screen and check the settings of the second monitor connection. You must turn it on, and have it set to a low enough resolution for the monitor to work. If it shows the second monitor, Click Identify and it will put a number on the laptop screen. Which ever number doesn't show up is the external monitor. Select it and set the resolution down by grabbing the scroll bar and drag it to the left. Start at 800x600 or so and apply changes. If the monitor doesn't come on, check to see if the monitor is on.
