OSD Setup & Calibration

OSD Tour

The MG24UQ’s OSD is well organized and has pretty much everything a tweaker could want, starting with seven picture modes. Racing is the default, and we found it came pretty close to all our standards. Close enough that calibration isn’t really necessary. sRGB is equally accurate but locks out all adjustments including brightness and contrast. We made a few changes in the User preset to achieve test results that rival many professional screens.

It’s getting hard to find a monitor without a Blue Light Filter these days. Asus offers four levels (zero is off) of compensation. Dialing in a little extra warmth will reduce eye fatigue, though you’ll sacrifice some color accuracy at the same time.

The Color menu has everything you need for calibration except a gamma control. Fortunately that’s not a major issue. We’ll show you our results on page four. User mode is the only way to have full control, but since Racing and sRGB are so good out of the box, we think few will need to take the time to calibrate their MG24UQs. We tweaked the RGB sliders a bit and lowered the Contrast control during our tests.

More picture adjustments are available in the Image menu. Sharpness should be left on its default setting to avoid obvious ringing or softness. VividPixel seems to sharpen color transitions, although to our eyes it provides neither benefit nor harm. ASCR is Asus’ dynamic contrast option. It can improve perceived contrast at the expense of highlight and shadow detail. TraceFree works well on its highest setting to reduce motion blur without causing any ghosting.

You can see by the input selector that only HDMI 1 supports the MG24UQ’s full resolution at 60Hz. The other two are version 1.4 and max out at 30Hz.

System Setup contains two screens of options including selecting from 21 languages, volume, DisplayPort Stream (version 1.1 or 1.2), ECO Mode, and OSD Setup. Here you can also lock out the bezel keys, turn off the power LED, and view signal information. There is nothing here to indicate FreeSync operation. For that, you’ll have to open AMD Catalyst.

MyFavorite refers to the MG24UQ’s four settings memories, which can be managed here. This is a handy way to make quick changes for different gaming or application environments.


The MG24UQ is one of the few monitors that can be simply be plugged in, turned on, and enjoyed. Aside from setting Brightness, there is little that can be done to improve its excellent and accurate picture. sRGB mode offers similar results but locks output at 170cd/m2. If you want that last nth degree of performance, choose the User preset and adjust the RGB sliders and Contrast control as we did. That will net you a tiny gain, but honestly, we couldn’t see a difference and you likely won’t either. Considering its price, this is pretty impressive performance. Our recommended settings are below.

    I honestly don't think that a 24 inch monitor should be reviewed as gaming monitor. Anything below 27 inches does not provide that deep, immersive experience.

    The difference between a good 30 inch monitor and a 24 inch monitor is the same as going from a 17 inch to a 24 inch. Once you experience it you can never go back.

    24" is a bit on the small side for UHD. I'd step up to 27-28" for that. Thankfully, 27-28" LCDs are also steadily coming down in prices and that includes UHD models. In many cases, UHD is displacing similar size QHD monitors in price.

    If this keeps up, UHD is going to become a really tempting mainstream desktop option next year.

    I have a friend who plays on a full hd monitor with a playstation 4. He pretty dedicated to console gaming, and is considering getting either a ps4 pro or xbox scoprio when they are released. Even though these consoles do not output native 4k often, its hard to dispute that the experience is substantial improved on a 4k screen. For him, something like this screen, or a follow up about a year from now, that costs between $250-$300 along with a mid gen console could be a great combination. 24 inches is a little small, but it is not as bad when you consider that most games are less than native 4k, and the smaller the screen, the less you notice upscalling artifacts.

    For high end pc gaming, 1440p144hz is still the best around today. I absolutely love it.

    Toms, can you start including information regarding scaling method/interpolation used on these uhd monitors, along with a subjective analysis of what it looks like at 1080p on the uhd monitors? Even a 1080 struggles with 4k at ultra in games, and once we start seeing uhd monitors that can hit 144hz, it becomes a really important consideration if the 1080p downscaling is ok or looks blurry.
  • Are these monitors HDR? I have 10-bit 24" asus monitors, IPS, which have been amazing. Seeing this, I might be replacing them. But, are they HDR? 10-bit and HDR are different, from what I understand.
  • photonboy
    You can scale on the monitor itself, OR on the GPU. If you setup GPU scaling then it always sends a 4K signal to the monitor so all scaling is done on the graphics card.

    I don't see much issue with scaling from 1600x900 or 1920x1080 to a 2560x1440 resolution using whatevever method the GPU or monitor provides (tried both).

    1080p is technical ideal to avoid certain scaling artifacts as it divides evenly, though things like aliasing (jaggies, shimmering) are far more important to avoid IMO.

    I'm not sure what control we have in terms of upscaling options. Again, a game is rendered at a particular resolution and the GPU or monitor handles the scaling. Not my area of expertise I'll admit.

    What would really be nice as an interim monitor would be one that would work at the interface limits of UHD (60hz), but if ran at a lower resolution, bump up to 144Hz (QHD, FHD).... I know I know, "Why would you run at less than native," right? "The complexity for LCD is more complex and will drive the price up." etc. etc. One can dream, even if such may not be feasible.

    There was a sony TV line that did that (it accepted 4k/60hz or FHD/120hz), but I haven't heard of many people actually using that feature.

    To be honest, 4k/60hz and 1440p (or even 1080p)/144hz modes on a single monitor makes a ton of sense for a monitor, choice between Eye candy and smoothness on a click of a button.

    40-120Hz Adaptive Sync would be even better.

    nice monitors coming out these days but can't we have DP 1.3 already?
