BenQ Xl2430T Horizontal Line

[GioXmen]

Hello,

I have recently noticed a Horizontal line on my benq xl2430t.The line is brighter than the rest of my monitor.The line is not very noticeable until I watched a movie with a grey scene where I noticed it and now I just can't stop seeing it.Once you notice something like this it just won't go away...

Firmware version - V001

What I have tried:
Pushing,applying pressure, giving it a small tap.
Unplugging the DVI cable from my PC and it was still on the benq boot-up logo.
I have the latest display pilot installed (2.22) - not fixed.

I will try:
Install the latest NVIDIA drivers. - - - Did not work.
Rebooting my computer after completely draining all of the power from the monitor. - - - Did not work.

Is there any way to fix this or do I have to ask for a replacement since I got this last Christmas(2014) and it has a 36 month warranty.

Looks like the boundary where your browser turns from white to BLACK (not blank, typo) along a window pane.
That's pixel persistence burn-in (not true burn-in though). You can remove that by having a pure white screen to reverse the polarity of it for a few days.
Unlike burn in of CRT's or OLED's, this isn't permanent. LCD's don't get burn in, although it looks similar. It's pixel persistence caused by voltages being frozen at a certain state, but it's reversible (although it can take a long time!)

Try http://www.jads.co.uk/screen-repair/jscreenfix-deluxe.

To avoid problems like that in the future, don't leave a browser window or a static high contrast boundary effect on your computer without a screen saver running, or leave your monitor on at night, with a browser window open on it.

I meant black earlier, not blank.

Someone where said that the natural color of a LCD panel is *white*, not black, and that you add voltages to a panel to make an image black, not turn down the brightness (backlight). This is of course different than CRTs or OLED's. That's why doing a pure white burn to fix pixel persistence "burn in" on a LCD works amazingly well. I think the jscreenfix deluxe page says pure white burn was recommended by Apple.
