    Laptop screen duplicated to second screen - goes dark random


    Hello,

    I have connected Acer ES1 572 laptop (1366x768 res) to larger 1440p screen via HDMI cable. The problem is that once in a while the larger screen goes black, totally random (goes back to normal in 1-2 sec). If writing and doing nothing special feels like not that often. Opening windows in a web browser, it's more frequent, or writing in Discord.

    Is this an issue with drivers, HDMI cable or something else? Quite frustrating with "blinking/black" screen (original is OK).
    The HDMI cable is quite long, about 5 meters. Could the signal get too weak if some strain that loose connection?
    It does not matter if both screens are on, or just the larger one. Still the same blackouts.

    Any help is appreciated, thanks!

    :)

    6288 - screen goes dark after 15 seconds

    Hi

    Have just purchased a 6288. Screen goes dark after 10 - 15 seconds if you don't touch the keypad - very annoying if reading a message. Have turned Power saver and sleep mode off, but screen still goes dark. Does anyone know how to stop it from doing this?

    Thanks

    Laptop with broken screen How much?

    I would like suggestions and look in local stores. I dont wanna buy a laptop from someone online. Sorry. But could be a good idea if you asked him about the performance on older games. Gonna make a list ofall laptops people suggest me.

    Remove the screen for space purpose here its small desk and if the screen is opened it will hide my 22 inches lcd

    Laptop screen duplicated to second screen - goes dark random

    my second screen is no longer recognised/working.

    Hi Hans,

    You may have to re-specify the display style on your laptop. There's a possibility that your laptop is currently set to only display the PC screen. Let's change the display style to
    Extend or Duplicate and see if your laptop will recognize your TV as the second monitor/screen.

    By the way, please ensure that your TV is properly connected to your laptop using a VGA, DVI, HDMI or DisplayPort cable, then follow the steps below to change the display style:

    • Press the Windows key + P.
    • In the right pane of your screen, the following display styles will appear:

      PC Screen Only

      Duplicate

      Extend

      Second Screen Only

    3. Select either Duplicate or Extend.

    Let us know how it goes so we can assist you should you need further help.

    Regards.
