    When I open a new page (like Finder) and extend it at full screen, it looks like I cannot completely cover the entire iMac screen with the newly opened page no matter how much I extend it. I still see some gap left between the page and the bottom of the screen showing my remaining desktop picture. (See pictures below)

    I'm also not sure if my iMac is suffering with the black-light bleeding problem or not. Please advice. Thanks

    The inablilty to fill the screen is not a problem with the iMac, but rather something to do with how apple wrote OS X. It's like that on ALL MACS. Silly, I know...

    IIRC, the backlight bleed is a symptom of the H-IPS panel (and the fact that Apple didn't put a polarizer, which itself causes other color distortion and increases cost). IPS without a polarizer won't do great blacks (which look silvery in the corners, depending on your viewing angle). This isn't the same as backlight bleed. If you center your face on a corner, then the rest of the screen with look silverish. Just look at this google image search:

    In short, the corner glow is not a defect, but a symptom of the screen not having a polarizer.

    I thing it is consider as the backlight bleed.

    since the off-angle glowing is affected when you look at a side angle instead of straight.

    But your picture is taken at a straight angle, which leads me to believe that it is a backlight bleed instead of off-angle glowing.

    Correct me if I am wrong.

    This is how my panel looks. I think is backlight bleeding.

    You have the Dock on the bottom of the screen and hidden, don't you? If so, that's why there's that little gap there. The UI keeps that there so that there's always a couple of pixels there to trigger the Dock in. See the two screenshots from my MacBook to see what I'm talking about.

    It's annoying, but it's NOT a defect. All new iMac's have this "issue". Hopefully Apple adds a polarizer for the Rev.2 iMac.
