    You can always connect an external monitor if the built in display goes completely south…

    There is not a lot that can be done easily. If you are still in warranty go ahead and open a ticket with Acer support. If you are out of warranty then it might be repairable by replacing the eDP cable that runs between the motherboard and the display. We'd have to know just which model you have before we can provide any more concrete suggestions. Your full model number is usually on the same sticker as your serial number, it should look something like xxxxx-xxx-xxxx.

    Also Take a look at the cables for any damage or loose connections. It might also be due to incorrect connection. Remove all the cables and reconnect them, especially the video cable connected to the monitor. Now, switch on your system and check if the horizontal lines are gone.

    Hi I have Acer C24-1650 and there are no loose cables etc because everything is housed inside the unit.

    Yes, the eDP cable is inside the case, connecting the display to the motherboard. With the stand removed, including those four screws, you pry the case apart gently:

    From there you remove the cover over the motherboard and the cable is toward the top:

    To get the cable disconnected at both ends, you have to remove everything… But often just disconnecting and reconnecting it at the MB will clear that type of issue up, since that tends to clean the surface of the contacts.

    Hi thank youfor your answer. But under the there was the metal cover which you had to unscrew. But then I not sure, what does 1 stands for do I have to lift or pull something ? I guess that 2 means that I should pull the blue flap? And I don' t what to use any force, it feels as if the connector is a tight fit.

    #1 is the lock plate that you rotate to release the cable. See how the arrow shows the rotation? Flip it up and the cable should be free…

    Hi, thanks for the explanation and it worked allright to remove the cable and put it back again. But, I am sorry to say, the lines are still there.

    Not a good sign then, since it's less likely to be the cable itself. Diagnosis from this point gets more problematic. The issue could be any of several things. It could be the panel itself, the cable itself, the motherboard or a noise induced by other components. Likely it's going to take a decent technician to dig in much deeper. The most likely scenario is the cable, with an internal crack inducing resistance in one of the traces. Second is induced noise from something like a failing power circuit, but I think that would show more as random glitches rather than specific lines. Third is the panel, which would be an expensive fix.

    Thanks, I'll will think about any next step or perhaps try to live with it as the computer and programs work okey.

    Well, where do I connect it, but, the lines are possible to live with so far, I may try to find an Acer station in Sweden if the problem grows worse.

    On the back of your system:

    That HDMI out port can be used to connect a second monitor. With a second monitor attached you can tell Windows to either duplicate the first monitor, giving you exactly the same display as the main monitor, but without the artifacts, or extend to the second monitor, giving you a larger desktop.
