M911 dell monitor not seen by computer

Hey Roger,
Below is information that should help you with trying to get monitor and notebook screen to work.
First make sure your laptop is equipped to be able to connect a secondary display, there should be a port for connecting a standard monitor cable on the back.
Connect your secondary monitor and reboot the laptop, the system bios should recognize that a second monitor has been added.
Then right click on your desktop and bring up the display properties dialog box.
Select "settings"
Your laptop should be identified as monitor 1 and you should also be able to see the secondary monitor as monitor 2.
Click on the secondary monitor and check the box that says "Extend my Windows desktop onto this monitor".
Set your screen resolution and color quality for the second monitor and click apply.
Directing icons and browser windows over to the other monitor is just a matter of drag and drop.

Thank You,

I have a strong suspicion that you have burned a capacitor or two on the monitor. You will need to bring this in to have it serviced as it will require the monitor to be opened up and new capacitors replaced/resoldered.

hi you could alter the resolution for the projector and see how that goes

right click on the projector an click on the properties tab
click on compatibility tab
tick the box and click on win 7---apply and ok
if it worked on win xp and you changed to win7 and doesn't work indicates a compatibility problem or driver for it in win 7

This sounds like an actual Video card problem, if it is possible, it must be changed with a new one..

To verify that your laptop is function and the monitor is now. Try plugging your laptop into a regular computer monitor. If the computer turns on and displays an image on the secondary screen, then you'll need to look into having your laptop screen repaired.

This could be either that your screen has failed, or has just become disconnected somehow from the screen to the laptop motherboard on the inside of the unit.

You have bad El-condensator on secondary side of power supply.
