This is on the Sceptre E24 LED Monitor, I can’t recall how long I’ve had it, maybe a couple years? The problem started down by the taskbar, slowly migrated up a bit, and then started a line in the middle, I left for a week (the computer was still being used) and now the lines in the middle have multiplied like bunnies. I think I might just need a new monitor soon, but what could have caused this? The monitor doesn’t get man-handled, it hardly gets touched, I happened to think that there’s a little curio cabinet behind it that closes with magnets, but I thought magnets didn’t hurt LED displays? The other things I can think of are the heat maybe, and the fact that it stays on all the time (I knew I was risking ghosting, but have never seen this,) and that maybe there are bugs or something inside the monitor messing with things? I used to have an ant problem by this desk, it seems to be resolved, but maybe there’s some inside the monitor? I was going to open it to see if there was anything visibly wrong or if I could fix it, but there isn’t an obvious way to open it, and for now it still technically works lol. The problem escalated very rapidly though. Any idea what may have caused this?
