Defective IPS panel ? :-(

Hello all..,

Making this new thread with much haste & anxiety..
Got my new 23" Asus IPS LED panel for 370 USD just about a week back. I did notice this on the very 1st time I switched ON the monitor but ignored it as I'm completely new to the LCD/LED world.. (been with CRT's for past 18 yrs)

What have I noticed ? Once the monitor is ON and I have a dark black background (like the one that appears on the windows dual-boot OS selection screen).. I see an area at the bottom right corner of the screen near the power ON button that is very brightly lit with a white light apart from the rest of the screen..

pls. see attached pic below..

Read about dead/stuck pixels online.. but I believe / hope these appear usually as a white or black dot on a dark / white background respectively.. but in my case, the entire arc like area is brightly lit..

Alternatively, when I'm on a high contrast white background, this area has a "very very very" (i might be wrong) slight tinge of a blue shade...

This white area is not visible when on any other colored background..

opinions ?

Is this something to do with dead/stuck pixels or is it backlight bleeding... how serious is backlight bleeding ?

Just read the manual.. and it says. . zero bright dot guarantee.. and a replacement can be obtained when there is >0 bright dots.. does this kind of a 'fault' come under this category ?

I have got pics of the screen but cant post URL's.. mods.. pls. remove this restriction for me..

Nothing would be wrong with the back-light. There are two possible problems:
1. The monitor is not receiving a signal, or the signal is not working properly. This is caused by either the device connected to it not working properly, or the monitor has a broken wire, or circuit.
2. The LCs are defective. This is unrepairable.
