Connecting an external monitor to acer 5720

I have an external monitor I used to use with my acer 5720 but when I went to connect it recently the external monitor goes straight to standby and my laptop monitor goes black but I still have sound. The monitor used to work fine with this laptop and still does work fine with every other computer in the house. I must of changed some settings somewhere but cant figure out what I've done? Help please :o(

I have had this before with my Dell Latitude C540/640. I don't know the ACER 5720 but here's a couple possible fixes for you.

1. Press the function key ( "fn" key, generally a blue key or blue lettering and usually in the bottom left corner of your keyboard) and press F8 (may be a different key on your laptop, again, not familure with the acer. The key usually has either CRT/LCD printed on it, or two monitors on it, one its just an outline of a monitor and the other is filled in. This will run you laptop through the three monitor options it has. (LCD - LCD & External - Just External)

2. Try closing and opening the lid of your laptop. Sounds a bit strange but it works sometimes for me. My guess is when you close you screen it would "dim/turn off" the LCD and re-opening it convinces it to turn the screen back on.

Hope this helps!

If you connect the monitor, power on the monitor then boot the laptop, it should default to the external monitor.

Hi.

Sure you can with a standard VGA video cable.

Maybe you will have to change your screen resolution to get the best display layout.

Hope it helps!

My acer 5720 is dead battery is good and ac is connected it just wont start


Hello,

The problem is with the corrupted boot files .In my opinion you have one solution
Steps for solution

1. Download an operating system called ' Linux mint ' which can be installed in the pen drive having minimum 4 gb capacity . Using this operating system you can access the computer .

2. Copy the file and folders to an external storage device (external hard disk, pen drive etc..)

3. Reinstall the operating system ( XP,Vista ,Window 7,Ubuntu etc )

Hope you be successful

Just changed the LCD screen on a 5720 and all I get is the backlight and a light blue screen....is there a reset or something i missed?


connect to an external monitor, and boot your system, and install the drivers for your new monitor.. should work.

if not, then the compatibility of the new monitor you hooked up, isn't good.

Connection to external monitor stopped working


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.
