There isn’t a good lag tester on the market that can do 2560x1080 natively. I’m sticking to using the Leo Bodnar lag tester at 1080p because it is a well-known, reliable test that is easy to duplicate. Most scalers also introduce very little delay now compared to color management and other display features.

The ASUS MX299Q helps make my point here in that even scaling the image, we see only 9ms of lag overall. No one should find fault with the performance of the MX299Q when it comes to response times. This shows companies can design displays with very little lag, even if a scaler is introduced into the signal path.

The MX299Q certainly conserves power. The most it pulls down is 38 watts, and normalized for screen size it winds up as one of the more efficient models that I have tested. Excellent results here from the ASUS MX299Q.

The gamut of the MX299Q also performs a bit over expectations at 75% of the AdobeRGB space. It isn’t close to enough of the AdobeRGB space to use it in that mode, but for sRGB material it will work very well.

    Hmm, would love to see a few images from FPS to see what they look like on a 21:9 - do I get useful additional info or is everything so fishbowled or out of my direct sight that it isn't a positive?

    There is a gallery in my prior 21:9 display review with some gaming images comparing 16:9 to 21:9 screen area. Those can be found here: http://www.anandtech.com/Gallery/Album/2630

    >>"The lowest black level any meter can reasonably measure is 0.0001, which would mean a peak white level of 8,000 cd/m^2."

    Actually, that's not quite fully accurate. Some expensive million-dollar meters can measure light at the SINGLE photon levels (Hint: They're used to detect neutrinos). There are some lab-quality meters at the thousand-dollar level that can measure less than 0.0001cd/m2. It is only a simple matter of how much you're willing to pay for a light meter.

    A more scientifically accurate way to say this is "The lowest black level any _consumer_ meter can reasonably measure is 0.0001"

    I'm only referring to meters that would be used for measuring displays, like this. At the high end there is the Konica Minolta CS-2000 for $26,000 that can measure down to 0.003 cd/m2 and the Klein K10-A for $5,500 that measures down to 0.00006 cd/m2. Regardless, any contrast number out there that is past 100,000:1 and it's an OLED is playing games most likely.

    In your spec listing you mention 1 Year warranty, However in the EU the minimum warranty for all electronic devices is 2 years.

    And incidentally, because most people are not aware of that, many shops and manufacturers pretend they are doing you a special favor by giving you 2 years warranty., but hey that's commercialism.
    And some are quite incredibly rude and don't mention that fact when they try to sell you additional extended warranties, including big companies like apple I hear.

    Quite outrageous to not have VESA mounting holes on a monitor in my view, but I guess they sell anyway so it's not going to end any time soon that manufacturers do that.

    I'd have already purchased one if this panel had VESA mounts or 120hz/lightstrobe.

    On the input lag, it isn't split up like the other screens are shown, the first segment showing input lag and the second segement showing pixel response times, but on this display is it 10ms pixel response and no input lag at all ?
  • Larzy - Tuesday, September 24, 2013 - link

    If that's true, then 9ms (rather) it's certainly one of the best 21:9 for gaming.

    No, this has been discussed as using SMTT allowed for breaking it up into two separate measurements. Since SMTT is no longer available and the license has expired, I can't use it to test anymore. Now I just have a single lag number that encompasses both of them. It's unfortunate but the way it is.
