    This was posted on a back of another thread, but I don't think anybody was reading it (hopefully), so I am reposting it as a new thread. Feedback would be greatly appreciated!


    Could I ask someone to try the following procedure out, as I want to make sure its not a common thing that is found in all the Z500 series laptops.

    So I have the Z570N. Could you guys try the following steps and confirm whether you observe the same thing or not? Doesn't have to be Z570N.

    1) Set your brightness to full 100%
    2) Open up a white background (like notepad maximized).
    3) Sit equidistance from both left and right edges of the screen.
    4) Is your left edge of the screen dimmer than your right? Its a very slight dimness that occurs in a gradient extending maybe about an inch from left edge of the screen that most people may not notice at all (if this problem is not unique to my laptop). In other words, if you had to find the dimmest part in your screen, where is it located? Left edge of the screen?
    5) Now move your head left and right, and compare the brightness on both edges of the screen (try about the same angle from both sides). Notice any difference?

    Like I said, its hard to spot it unless you're looking for it (once again if this problem is not unique to my laptop).

    This could just be the way the screen is lit in the back, or it could be that the heat damaged my LCD or the LED lighting.

    Before I send my laptop off for repair, I want to make sure that there is a problem to be fixed.

    Thanks for your help!

    i also notice a slight difference... originally i thought it was the lighting in the room i was in, but now i'm pretty convinced that there's a difference.

    for me, it's most notable in the lower right side.... that seems to be the brightest area.

    it's an annoyance, but i don't notice it much.
