    moving to an IPS panel is where it's at. I made the move back in 2008 after using many Apple IPSs at work... I'll never touch another LCD technology again... except OLED... which might not be an LCD technology...

    When shopping for monitors... do a lot of research and of course get a calibrator.

    Make your life easier and avoid wide range monitors... stick to sRGB unless you need it wider for photography or something.

    why not a korean? 27", 1440p, PLS (read IPS if you must), 120hz (or whatever you can get, 110hz pretty much guaranteed). for some $350, give or take.

    I might go for the AH-IPS 27", depending on the prices of the 30", over the next several months.

    Also, the only thing that prevents the back light glow is an A-TW polarizer but not many cheap IPSs have them.

    how much would that be? and can it do 120hz?

    Not recommended. The 30" IPS monitors are generally worse than their 27" brethren. The panels are wide gamut, which means oversaturated colors and a need to calibrate by hardware (colorimeter) to shrink the gamut back for color-aware applications (shrink = color loss). They tend to have rougher coatings, except if they are semi-glossy, then they might be fine. They tend to have more IPS glow too, so you'll have to sit further back and you might be annoyed. Then they tend to have lower contrast ratios which means the black levels tend to be higher (not good). Finally, they don't overclock to ~120Hz as the Qnix QX2710 27" Korean monitor or the Overlord Tempest 27" monitor do.

    Go for 27" 1440p if you're willing to upgrade.

    On the other hand, you got a very speedy TN that would benefit from pristine motion clarity by turning on LightBoost. I hope you're using LightBoost.

    My Asus VE278 does not seem to have a "lightboost" setting, I believe that setting is on newer Asus monitors.

    Oh oops, that is correct.

    How is a 10bit color gamut worse then 8bit? 10bit producing over 1 billion colors as opposed to the 8bit 16.7 million. Sure using an 8bit output to a 10bit monitor would require proper calibration as the color space is treated differently, but calling it worse is false.

    Most 30" IPS are also still CCFL backlit as opposed to many of the 27" IPS/PLS using edge lit LED, the CCFL lighting cuts back on IPS glow dramatically. The main problem with using LED lighting on an IPS screen is the edge lighting can cause a more dramatic IPS glow. Edge lit LED is also worse for the possibility of light bleed.

    The coating of the monitor is subjective to the users taste, have not checked myself but I would think these 30" IPS can be found in different screen coatings.

    IPS screens are also best for Black Crush, basically the smoothness of contrasting blacks.

    All monitors have their ups and downs. The Korean PLS screens are great for their cost, great picture, they can do 120Hz at the cost of running multiple color profiles because of the gamma shift, running a constant high Hz also causes image retention. These things can all be dealt with though.

    I'm afraid you got the terms confused.

    This is a color gamut:
    [​IMG]

    It doesn't matter whether you can use 3 colors in there, 12 colors, 16.7 million colors, or 1.07 billion colors. That's what 6 / 8 / 10-bit is for. 8-bit and 10-bit displays with the same color gamut will display the same shades of red, green, blue, cyan, yellow, magenta, white at intensity 255 (8b) / 1023 (10b).

    The majority of 10-bit panels (actually, it seems that all 10-bit panels that don't cost an arm and a leg) use 8-bit + FRC, which means the panel is still only capable of doing 8-bit but dithering is used to 'show' 10-bit gradients. TN panels are 6-bit + FRC.

    Again. That's not IPS glow. That's backlight bleed and uniformity. IPS glow is a product of the panel and not of the backlight being used. To compare IPS glow, two monitors are photographed in good ambient lighting conditions at a specific angle to factor out the backlight bleed, like below.

    This is an HP Z30i:

    From this review of the HP Z30i.

    Here's what he has to say about 30" and their IPS glow here:

    Here is NCX's Qnix QX2710 with no IPS glow (=Eizo EV2736W):

    From this review where you will find more photos of IPS glow for different monitors.


    Notice, grain free. Monitors that use grainy matte coatings can be annoying. The semi-glossy matte coating does reduce glare very very well.

    What about that? That sounds like gamma curve to me.

    Just about ready to order YamaKasi 27"

    Right now I'm thinking of ordering the Yamakasi DS270 27" IPS SE 2560X1440 monitor, off eBay for $330.
    http://www.ebay.com/itm/141014647239?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649
    (I do not think I need a monitor that overclocks)
    Might order the DS270 by the end of the day, unless someone can point out what a mistake they think I'm making getting the Yamakasi DS270?

    Edit, Ordered the Yamakasi earlier this morning, then got an email saying they closed down until Feb 2nd, for the Korean new year.
