    And yet others claim it's H-IPS. I have yet to see concrete evidence as to what type of panel it is.

    My 24" ALU ex-iMac had an LG.Philips LM240WU2-SLB1 (according to
    the panel firmware's DDC info block, as reported by SwitchResX). I've
    seen several other reports of the same panel in various Mac forums.
    Also, here's a photo of the panel P/N on a 24" ALU disassembled for a
    hard drive upgrade:

    The white 24" reportedly (via SwitchResX) used an LM240WU2-SLA1.
    It's anyone's guess what differences the SLA1 vs. SLB1 suffixes imply.

    Although I've seen no documented reports of other panels in the 24"
    iMacs, it's quite possible that they exist. Apple used both S-IPS and
    S-PVA panels in the 20" white C2Ds, and some Dell monitors do the
    same.

    BTW, there's nothin' wrong with S-PVA; most Eizo monitors use them.
    Neither is inherently superior; it's a matter of preference: S-IPS has
    slightly better viewing angles and (some say) slightly more faithful
    color rendition, while S-PVA has better black levels and contrast.

    I'm not sure there's any difference between S-IPS and H-IPS (other
    than marketing hype). The panel data base on tftcentral.co.uk has
    conflicting classifications of the LM240WU2 -- it's listed as S-IPS in
    one table, and H-IPS in another.

    There's a difference between the two. H-IPS has no purple hue when viewing black background at an extreme angle. http://en.wikipedia.org/wiki/TFT_LCD

    Perhaps SLB1 is H-IPS and SLA1 is S-IPS?
