Faint white line on monitor

[Liamoconn]

Hi, I've been noticing on my monitor recently that there is a faint white line going horizontally across the screen, it is most noticeable on a grey background. I could be wrong but I think if my monitor is turned off for a while it seems to fade away but I'm not sure. It's been like this for about 2 months or so. Please help if anyone knows how I could fix this without getting a new monitor

Monitor - Acer GN246HL Bbid 24-Inch 3D Gaming Display 144Hz

There is no chance to fix it without repacing whole screen, cheper way would be to buy a new one.
You should give it a check with a different cable but i dont think its gonna change anything 😉

Replace the VGA cable with a more Shielded one and isolate the VGA cable from other Cable and Devices. I too have this problem but with a laptop when the laptop is plugged in the white vertically-scrolling-horizontal-lines, when the laptop is on battery the line disappears. Also try isolating the Monitor power from other devices.
