I have an Aoc AEGON 1440p 144hz monitor and found that I turned it on today and the monitor has a vertical line of pixels all the way from top to bottom that are permanently blue.. It I unplug the display port cable or change the input selector the blue line stays on display. If however I wiggle the power cable in the monitor the line on screen goes for a good few hours then reappears later.
Anyone know what this is?

Sounds like A "stuck sub-pixel"
A stuck sub-pixel is a pixel that is always "on". This is usually caused by a transistor that is not getting any power, and is therefore continuously allowing light at that point to pass through to the RGB layer. This means that any given pixel will stay red, blue, or green, and will not change when attempting to display an image. These pixels may only show up using certain applications, or they may be on all of the time.
Can you try another monitor ?
How old is that monitor ?

Does the old monitor work that you replaced this one for ?
What are you connecting to a Desktop ?

Then I'd have to guess the monitor is bad if it still exhibits a problem being disconnected from the computer. I can't explain why the problem goes away when you wiggle the connection when it's connected to the computer. That's an odd one.disconnecting it completely from my Computer but turning on the monitor with the power switch still shows the blue line
Yes you could try the display port cable first.

The blue line displays until I touch the power pin that's connected between the monitor power jack and the power brick then it's fine for the session
OK. I'm having a hard time picturing the exact connection type, but if there is a cable that you can be replaced that's where to start.
I googled the problem to see if anyone else is experiencing the issue but did not see anything.

If I wiggle the power cable.. The blue line goes for a while then returns and I must wiggle the power cable again to resolve

Hello,
You need to take this back since it's bran new, it could be a loose connector at monitor of which I don't know how to fix, or replace the power cable, from my experience i would be more prone to thinks it's the connector at monitor.
Can you take it back or at least call them ?
