Hello,

I have an Acer Predator 4K monitor - XB271HK which is 4 years' old.  Yesterday, thin black lines appeared across the whoel screen. They are approximately 2mm apart.  I have tried moving the monitor and also plugging in to a new device with new cables but the problem persists.  It is visible on the splash screen and menus also.  Is there anything I can do?
