My laptop screen becomes empty whenever I disconnect the plasma

Recently, I connected my computer laptop to LG plasma to see a movie (using RGB output) and changed the accodringly to display definitions. However, when I disconnected the cable from the laptop, the laptop screen became blank. When I reconnect the cable - I see the laptop screen (even if the plasma is off). Now I'm stuck to work with a cable connected to nothing...

When you restart the computer, I see the screen, it disappears when windows comes on.

I've redefined (by using windows + P) the computer screen only - did not help. I've updated the display adapter and monitor in Device Manager - did not help. No virus detected; Nothing to do with the BIOS...

Ideas please?...

Hello

I suggest you to uninstall and reinstall the drivers to display the computer manufacturer's website and check that I get no help.

    Hi Bilipino,

    You have more than one display card? Try to connect your monitor to the another card and see if you can get the display.

  • Whenever I disconnect the computer a box comes up saying "" you sent emails in your Outbox you want to send ".

    whenever I disconnect the computer a box comes up saying "you sent emails in your Outbox you want to send" I always click Yes although I already clicked on send at the time writing e-mail. "." How can I remove this box?

    Hello

    Just because you clicked on send after writing the e-mail, does not mean he's actually gone.

    Open your e-mail, all program what it is and see if something is still in the Outbox.

    If there is, remove it, that means you have a problem with sending emails.

  • Keys on the keyboard of the laptop does not match the characters typed on the screen after having connected and disconnected the separate keyboard

    I have a Dell Vostro 1310 (laptop).  My laptop keyboard was working fine until I decided to plug in a keyboard separated from Dell on the USB port, just to give my fingers a break from typing on the small keys of the laptop and then unplugged the keyboard to the keyboard of the laptop again.  Now, when I type using the keys of the laptop, some keys produce different characters on the screen.  This is what happens:

    "uiop' became keys ' 456."
    "jkl;" become "-123"
    "m" becomes "0" and
    '0' becomes ' / '.

    I think it may have something to do with the left button "Fn" Blue right next to the 'Ctrl' key on the lower side of the portable keyboard, because characters that appear match the blue characters on these keys with a malfunction.

    Can someone tell me please how to get these keys again function normally and to prevent this from happening in the future?

    I found the answer on another forum on the Internet.  Press SHIFT + Num Lk to deactivate the mode of operation.

  • Laptop screen disabled when connecting to a projector

    Original title:

    Hello, I am trying to connect to a projector Acer H5360 to my computer dv9750 Pavilion laptop under Vista Home Premium using an HDMI cable.

    Whenever I connect the projector, or noting happens and typing FN + F4 I can have my proposed office or automatically after a certain time, my office is planned (without typing anything). In both cases, the office disappears from the screen of my laptop (!)
    The only way to have my laptop active screen is again by disconnecting the HDMI cable AND it's not completely deterministic: it happens that the laptop screen remains inactive after extraction of the HDMI connector and until the power is cycled
    My question is how can I configure the system to always reflect the tower to the projector screen, whenever the projector is attached, while leaving the tower still active screen? before, during and after the setting of the projector.
    I would add only that I did not imagine it's be so complicated to just fix a projector. For example, when I move the same projector with the same cable to my xoom Tablet I just see projected! without doing anything more than the * physical connection *.

    How many times do you have to press the key combination?

    FN + F4 key combination is to switch between monitors. Try pressing the fn + f4 several times until you get show both monitors ON.

    When the monitor of the laptop is turned OFF and the projector is on, press the key combination, the projector must be OFF and the monitor of the laptop must be turned on. By pressing the key combination twice turns the laptop screen and the projector. There should be no instance that both will turn OFF.

    If it does not try to activate your dual display:
    Right click on the desktop-> Output To-> Intel Dual Display Clone-> notebook + monitor. It can vary in defense on your installation, I use a laptop HP and Acer LCD as a second monitor.

  • Computer DV7-1825dx laptop screen turns off at least connected to the HDMI

    I have a Pavilion dv7-1825dx running Windows Vista Home Premium 64-bit.  The other day, I simply closed the laptop into hibernation.  At the time, it was only connected to a printer and a wireless mouse.  The next day, I opened the laptop and it turned on but the screen stays off.  I shut down the computer by holding the power button and then turned back on.  The screen appeared and asked me if I wanted to start Windows normally.  Then, I got the loading screen for Windows.  As soon as he was done loading, the screen turns off and the chime sounded for the login screen.  I repeated again than having the same problem.  I typed my password, but the screen stays off.  Because I often hang my computer to our TV via HDMI, I thought I would try it, and that is, both screens lit.  I then disconnected the HDMI cable and the computer screen exploded again.  Plugged into the HDMI and activated.  I went into options for NVIDIA and noticed that there is an analog display with the screen of television and laptop (up to three screens on the list).  I restarted in safe mode, and the screen of the laptop works great.

    Any ideas on how to solve this problem?  That I can not connect my laptop to the TV whenever I want to use.

    Thank you advance!

    Save the driver on the desktop and install it from there, not in a temporary folder.

    Create a Windows restore point before starting.

    During the installation of the new driver, click on "Custom" and there will be a link to uninstall the old drivers and all of your current settings, this before you install the new driver.

  • C855-13D satellite after 5 minutes, my screen becomes dim

    Can someone help me please?
    I use a laptop Toshiba Satellite C855-13D with 64-bit Windows 7.

    After 5 minutes, my screen becomes dim unless I move the mouse.
    In order to disable this I need to go into the Advanced mode in eco service department.

    But on my laptop there is no Advanced tab. I've got report and help settings.
    No advanced. I went on YouTube and saw the Advanced tab there.

    So why missing on my laptop and how can I get it back?

    Hi demoome

    I think that the ECO profile has been selected in Win 7 power Managemnt.

    You can change it easily.
    Go to control panel (change the icon display, small or large)-> power management
    Here you will find plans of different powers.

    Choose the one you want to use: for example the balance.
    Now, click on change Plan settings

    Now, you can find the option called the brightness
    Here, you can assign the value of the battery and AC adapter mode.
    Finally, apply the changes.

  • Screen goes black whenever I move my Equium A200

    It is not easy to say with certainty why this happens, but I guess that there must be a contact between display and motherboard problem.

    Thanks in advance. Steve.

    Hello!

    Press FN + F5 to switch between monitors.
    Check if you have the same problem on startup and in the BIOS.

    In the worst cases, you should go to a local ASP. Technicians must check your parts for laptop and trade if it of necessary.

Research in the preferences and general tabs seem to work normally. I upgraded to 10.11 of the OS, but I have had this problem since the previous version of Firefox at 10.10.

    Hello, you can try to reproduce this behavior when you start firefox in safe mode, once? If not, perhaps an addon intrudes here...
