BENQ XL2411 - Transparent bright line?

[citoxe]

I've had absolutely no issues with this monitor whatsoever, I go to bed and I wake up and I notice a brighter line across the screen.

It doesn't remind me of dead pixels however if I do unplug my DVI cable from the computer so that it says "No signal detected", I could still see the line.

 

If anyone's got an idea, please tell.

Everything is helpful because I'm really in need to fix the monitor due to not being able to afford a new one.

 

Thanks in advance, picture below to show you what it looks like. (See around middle of black line)
