    I keep staring at my screen and there seems something not right...

    Somebody talked also about too dim screen. This issue is also mentioned in the following review.


    I also have the blueish tint and my screen is very dim. The color white on my screen is actually blue/grey-ish. I also have impression my screen is "breathing." Rather than a steady color surface it's "waving" like a color sea-surface. This is mostly noticeable on white backgrounds. Unfortunately I have to read all day texts on white background.

    My questions:
    (1) Does somebody else see the blue/grey-ish tint on white backgrounds?
    (2) Is there somebody doing professional photo-editing who callibrated the FHD screen, and wish to share his color profile?
    (3) Is every screen (of the same model) "different"? Is it possible that my FHD has bad calibration whereas a replacement screen just works fine

    For #3 - every screen is going to be slightly different, yes; therefore someone sharing a color profile may not help. It might make your picture even less accurate, color-wise, but at the same time, wouldn't hurt to try.

    Irregularity Correction (UNIFORMITY)
    The NEC original dedicated image processing IC corrects the brightness and color of the screen and optimizes gamma correction values. Based on measurement data, it optimizes the correction value as appropriate for the display characteristics that differ slightly among individual LCD panels to deliver professionally required uniform display performance.

    A uniformity-correction function is a technology for reducing display irregularities. The uniformity referred to here refers to colors and brightness (luminance) on screen. An LCD monitor with superior uniformity has low levels of screen luminance irregularities or color irregularities. High-performance LCD monitors feature systems that measure luminance and chromaticity at each position on screen and correct them internally.

    This is a comparison of monitors with and without uniformity correction. An LCD monitor with uniformity correction (photo at left) has more uniform luminance and color on screen than one lacking uniformity correction (photo at right). The two photographs above have been adjusted to equalize levels to emphasize display irregularities. Actual irregularities would be less conspicuous.

    Somebody sees something similar?

    Perhaps the adapive brightness issue is messing up the hardware algorithm to correct the light on my screen? Or maybe my screen is just inherently flawed?
