I have a Dell, the screen is completely cracked, i cant see anything on it. and i'm trying to hook it up to my monitor. i can see my background/wall paper on the monitor, but i cant see my icons. i can see the mouse run along the screen, but its like the monitors picture is too big (is that makes any since) last time i pushed like FN and F4 or something, and it worked, and everything fit the screen. its been months now and someone turned my computer off and the screen and i cant remember how to do it. everything ive tried hasnt worked. any more ideas?
Try connecting a mouse and keyboard to the laptop and then start it with the top closed. Not sure if this will work on your model, but it works on a lot of laptops. This should force the PC to use your external monitor as the primary one.

You can switch to an external monitor or data projector by two methods. 1. Connect the external monitor to the laptop's video port, power up the external monitor first and the laptop. The video information will automatically switch to the external monitor. 2. If you power up the laptop first then you can switch the video output to the external monitor by pressing the Fn key and one of the Function keys, depending upon your make and model laptop. You can also toggle between the external monitor or both LCD screen plus the external monitor or back to LCD screen only by pressing the Fn key plus one of the function key. Here is a list of key combinations for some of the laptops :- IBM ThinkPad = Fn + F7 HP and Compaq = Fn + F4 Toshiba = Fn + F5 Dell = Fn + F8
Check your ports on the lap top see if you have s video or hdmi or dvi or VGA the best is hdmi if you have that get a cable for either one of you connections also match connections from the lap top to what you have for your TV more than likely if they are both fairly new you should have hdmi connections for both get a cable that is long enough. I get my cables at amazon.com their prices are the bomb.
Connect them together both ends to lap top and to tv then make sure that you have a line in jack stereo jack with RCA ends hook that to the back of your tv and your lap top in stereo jack even better to your surround sound system. Set your TV to AVI 1 or 2 or DVI or whichever is your connection start a movie on the lap top and turn your sound on and see if you have a picture on your screen you should have the same thing as what is showing on your monitor on your lap top. Adjust settings and have fun!
Check to see if you have the machine switched out to a stand alone monitor. This is a feature on many lap tops that lets you re-direct the signal out to a larger monitor, or if your monitor fails you can display the computer info on another screen. This feature is engaged by holding down the Fn key and tapping teither the F4, or F6 key on many lap tops. This feature can be toggled by both displaying at the same time or switched to the stand alone or the Lap top.
The other cause is that the machine has malfunctioned usually because of the CPU failure and there is nothing to boot the machine up.
To hook up the monitor all you will need to do it connect it to the
monitor port on the side or back of the notebook it
should just start displaying on your external monitor as soon as you
hook it up but if it dose not you may need to restart the system. Also
the port you need to connect to is the only port on the computer the
monitor cable will be able to plug into so don't be worried about
connecting to the wrong port on your notebook.
If you're talking about an external monitor to connect to your Dell, try to toggle the display by pressing Fn+F8 keys both at the same time to send the video to the external monitor.
Now, if you're talking about the lcd screen on your notebook, try running the dell diagnostics by pressing F12 upon seeing the Dell logo when you start the machine. select boot to utility partition and press enter. Diagnostics will run and test your system. There's a portion there that tests the lcd screen. It should give out a report that the system is okay.
If your LCD screen on the laptop does not display a picture and if you hook up an external monitor and it doesn't display anything either, then your video card is bad. But--before you go trash the thing, when you hooked up the external monitor, did you push the Fn key and the corresponding special function key at the top of the keyboard that switches the output to the external screen? (It does not just display to the external screen without you telling it to. What your uncle describes is a problem with the laptop LCD monitor, not the video card.
