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.
