Cannot connect external monitor to laptop

By jenn_rasmussen23 ·
I have broken the internal monitor to my laptop and am trying to use an
external monitor. However, the current internal monitor is completely
broken and I cannot view anything on it. The computer opens up with
the windows page, however, the desktop does not appear. I have
messed around with the function keys, however, there is no
correspondence to the external monitor. The problem might be that I
have a Toshiba computer which I purchased in the US and have a LG
monitor that I purchased in Europe. I am not sure what to do
considering I have no visibility on my laptop and the Function keys are
not working as well. Any suggestions?

Struggling to understand . . .

Either the monitor is broken or it's not broken - so how is it that you "cannot view anything on it" yet"computer opens up with the windows page" ?

If you can see the Windows startup screen, the monitor is NOT broken.

More likely your problem lies with your graphics card, which kicks in right after the initial Windows screen.

Why do you say that the Function keys are not working?

Have you tried to boot into Safe Mode?

Hit F8 as soon as the BIOS splash screen disappears, before the Windows screen and gain entry to your system that way.

You may have a problem with your Graphics drivers.

As to the Toshiba being American and the LG being European, as long as you can switch the LG on (presumably using some form of mains adaptor) the connection between them should not be of any concern.

possible solution

by jgawthrop5 In reply to Cannot connect external m ...

our 6-year-old daughter closed my wife's laptop with a pen in it and forced it closed shattering the screen. only the top 1/3rd was visible.

i origionally took off the monitor and connected an external monitor to the laptop and the same thing happened that happened to you. the monitor came on through the boot-up process... but as soon as windows was launched it went into power-save mode.

i hooked the monitor up to my laptop and it worked fine. so i knew it wasn't the monitor.

so i re-hooked up the lap-top monitor to the laptop and hooked up the external monitor... i then right-clicked in an area i could see. i then clicked on "graphics settings" or something like that and changed the screen resolution to like 800 something. then clicked on "send graphics to" and sent it to the other monitor.

it seems the problem was the screen resolution setting in the laptop was not compatible with the resolution of the new monitor. but now everything works fine.

hope this helps.

if you would like more detailed instructions let me know. i can pull it back up and look at what EXACTLY it said.

good luck!

old mycroft is correct

by zlitocook In reply to Cannot connect external m ...

Europe may have different video standards then we do so it may not work any way. But it sounds like a video driver or setting is wrong on your laptop. If you get any thing on the laptop monitor at boot up then it is not broken just trying to load the correct driver after boot up.
Press the F8 at boot up to get into safe mode, it could take a few minutes for your laptop to reach safe mode. If you get in to safe mode check your display settings and look at the hardware settings to see if there is a problem with your video driver.
You can unistall the video driver and reboot to let it reinstall. Just be sure to have your XP or your driver CD ready incase it needs it.
If you need more info ask me.

Possible Fix

by tom160298 In reply to Cannot connect external m ...

This will only work if you have 1 XP Pro/Vista PC that is CONNECTED TO THE INTERNET!!! and your PC/Notebook is also connected to the internet (NEEDS to be in in a home network!! and started up!):

Find the Name of the broken PC, then open up remote desktop connection (In vista you will find it in: Start, All Programs, Accessories, Remote Desktop Connection) Click the options button, Type the remote computers name, Enter the logon Credentials (Username, Password) and click connect! You will see your PC's Desktop. Maximize the screen by clicking the maximize button and use the On-Screen keyboard (Start, All Programs, Accessories, Accessibility/Ease of use, On-Screen Keyboard) to click in the combination. Once you click you special combination in, the monitor SHOULD start working! Once you have done this you can start using it! (If you want, you can select in the screen options (Again Using remote desktop with the monitor displaying nothing)Screen Number (What ever the screen number is) and pressing OK.This will Switch the plug-in monitor to be your MAIN monitor!)

About That laptop Screen problem

by com2pc In reply to Cannot connect external m ...

This reply assumes there is no damage to the INVERTER. Which is about The only thing that will prevent you from displaying on an external monitor. With some laptops you may find it necessary to choose monitor 1 OR minitor 2 from display properties, Monitor ONE would be the Laptop(LCD) Number 2, an external monitor.. My Dell automatically defaults to the external monitor when I plug the monitor up to the laptop. IF You cant see anything,so as to acess Display properties, THAT is another problem. I suggest this. With the laptop off. Plug a known working external Monitor into the display adapter on back of laptop. Then TURN on laptop. It should default to the external monitor. If It will Not you may have to seek professional help from a qualified tecnician.

Try with ext connected and laptop CLOSED.

by 1bn0 In reply to Cannot connect external m ...

Connect the monitor to the laptops VGA connector.
Turn the monitor on. The LED should turn green and then blink or fade to yellow. (powersaver mode).

Leave the laptop CLOSED. Turn it on.
MOst notebooks will automatically look for the external display if turned on with the display closed.

get your monitor fixed

by Jgates88 In reply to Cannot connect external m ...

the only other thought besides getting your monitor fixed is there may be a way to do it thru the command prompt, but I dont know if thats possible.
