Computer screen turns off when I plug an HDMI cable

Initially, I had both my tv and computer off. I plugged the dvi to tv and the HDMI to laptop and turned them both on. I had no problems using my laptop I tried to synchronize the computer to the TV. However I must have accidentally hit something in the graphics options as my laptop screen went black. I unplugged my laptop hdmi cable and the screen returns to the top. But now, for some reason whenever I plug the HDMI cable for the laptop, the screen goes black. When I take it on it the screen comes back to the top. I have something that is originally for this change? Any help would be greatly appreciated. Thank you

  • My screen goes black when I plug an HDMI cable

    I have a desktop Dell 660 s with Windows 8.  I try to be able to sync my TV led with my pc.  When I plug the hdmi cord, my monitor Gets a black screen.  The only thing that shows is the arrow / the mouse cursor.  My TV can not detect the computer.  When I unplug the hdmi cable, the screen goes back to normal.  Help, please.

    Hello

    If Windows is displayed on your TV, you will need to reconnect the computer to your monitor and adjust the screen resolution before connect you to your TV. If your computer does not support the type of video connection you need, you may be able to install a new video card that has the right connection.

    Step 1:

    After that you have the right cable, follow these steps to connect your computer to your TV:

    (a) turn off your computer and place it near your TV. Unplug the monitor, but leave the mouse and keyboard connected.

    (b) connect the appropriate video cable from your computer's output to your TV.

    (c) turn on your TV and set it to the input that matches the output on your computer. You may need to refer to the supplied with your television user's guide for instructions on how to do it.

    (d) turn on your computer.

    You should see windows displayed on your TV. If the screen looks stretched, or part of the screen seems cut off, you will probably have to adjust the screen resolution in Windows. For more information, see getting the best display on your monitor.


    Step 2:

    Try to activate and set the digital output HDMI as default device.

    (a) click the Windows key + X, and then Control Panel.

    (b) click on hardware and soundand then click manage audio devices.

    (c) click on the reading tab.

    (d) in the empty space of reading devices do a right-click and use the option to show all disabled devices, you should get a popup upwards with HDMI digital output.

    (e) If you find digital HDMI output Device, right-click on it and set it as default communications device.

    It will be useful.

  • Screen turns off when the Satellite A45-S250 is moved in the direction of less

    Hello.

    I have a satellite A45-S250. I had no previous problem with this machine. However, when the computer is running too long, or it is moved in the slightest way the screen turns off. I don't even have to type very slowly - or I lose the screen.

    But also, as I have said - sometimes I won't even be near the computer and the screen turns off. When I lose the screen if the light shines on it - I can see, it's always VERY fair Sun. Generally, it will come if I use the FN + F5 button.

    I don't know if it is a screen problem or a connection problem. It occurs with increased frequency. Any suggestion would be appreciated.

    Thank you

    From your description, I assume FL converter is defective and must be replaced. FL inverter is responsible for the background light and the typical symptom for faulty FL inverter is dimming or blinking display.

  • Equium A100 - screen turns off when I open the lid completely

    I recently had a problem with my Equium A100, as when I open the lid fully, the screen turns off.

    However, when the half open, the screen is completely visible.

    I have attempted to open the screen and can not see loose cables to my knowledge.

    Any help on how to solve the problem would be appreciated.

    I agree with Akuma. It sounds like a hardware problem and probably the contact loses when you open the lid.
    The cable screen should be checked and probably replaced.

  • Computer will turn off when the PXI chassis is turned off

    Hello

    I realized that my computer is shut down properly if I disable my chassis PXI-1036, until the computer is turned off. Is this a normal behaivour?

    As I remember, the chassis PXI-1036 must be turned on until the computer is power on, and I think that maybe on turn it off I have to follow the same procedure.

    Thanks a lot for your advice,

    Hector

    The chassis must be on anytime on the PC is.  Then it turn on before the PC and turn it off after the PC.

    This is because the chassis is an extension of the PC's PCI bus, so he expects everything to be available all the time the PC is powered on, as would be a PCI expansion card.

  • When I plug a hdmi cable my laptop turns off

    Whenever I plug a HDMI cable for laptop may it instantly stops and cannot restart until the cable has been disconnected. I only bought the laptop 4 months that when checking to see if something was faulty output HDMI was working fine; now, it will not work. When looking on Device Manager I couldn't find a driver for the port (is he wants to be one) and I tried to update drivers, but still the same problem.

    I have an acer aspire 5738z

    Usually, there is no driver listed for the HDMI driver.  HDMI is an output video "high-end" and it is usually controlled by the video card.

    Try another HDMI cable.   Try another TV.

    If the HDMI port always stops the laptop, you may need to take to a service center.  This could be a------hardware problem.

  • Re: Satellite L300 - screen turn off when it will be moved

    I have a problem with my screen stopping when I move my laptop or move the screen slightly. The computer does not turn off just the screen becomes black. I have to then hold the power button to turn off the computer.

    Does anyone has any ideas or had this problem?

    Hi Geg,

    You may notice this behavior on external monitor too?

    For me, this looks like a hardware malfunction caused by internal display or just the cable. You should ask a technician for laptop help.

    If only the cable must be replaced cheap s and takes a few minutes a technician for laptop.

  • my screen turns off when watching a dvd.

    It does on every 10-15 min 0r.

    If you wiggle the mouse, the screen comes back? If so:

    Depends on your set up etc, but it could be something like a power, option setting 'Change Plan Settings' and then either 'Dim display' or 'turn off the screen' options.

    Or maybe a setting screen saver, i.e. you have "Blank" selected kick after 10 minutes.

  • Satellite C50-B-12V: mic turns off when I plug the headphones

    Hello

    I recently bought a computer laptop Toshiba Satellite, Satellite C50-B-12V

    I'm really happy with my new lap top - thought I am facing a problem.
    It seems that the port to plug in headphones and the port to plug in a microphone is the same. so, if I plug headphones wireless for a Skype call, the other party can not hear me.

    Is there anyway that I can adjust the computer so that it shouldn't be a problem?

    Again, I would be able to plug the headset on my computer to hear my interlocutor better - and who have not cause the other party cannot hear me.

    Hello

    This integrated headphone / microphone port equipped with a plug of 4 section (identified with 3 black rings)
    You have two options to solve the problem mentioned.
    You must use a headset / microphone with jack combo or you could buy an adapter 'Y' which can connect your current helmet with separate microphone and speaker back to the headset / combo jack.

    Something like that:
