Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Easily adjustable stand
You can easily adjust the height of the monitor, and you can also rotate it and switch between landscape and portrait mode.
Pro Works well in brightly lit environments
The MG24UQ features an anti-glare panel, which significantly reduces or eliminates reflections, loss of clarity due to light, fingerprints and smudges.
Pro Detailed OSD menu's for easy navigation
ASUS has handled the on-screen display (OSD) of the MG24UQ very well in a clear and easy to navigate interface. You can choose from a different number of presets on the fly, and all attributes such as brightness, contrast and refresh rate are adjustable. The blue light filter can also be adjusted in intensity. You can also create your own presets for easy switching between settings.
Pro Excellent viewing angles
The viewing angles of the MG24UQ are excellent; no color shifting (distortion of colors) occurs when looking at the display from a horizontal or vertical angle.
Pro Well built and designed
The design of the MG24UQ is quite sturdy and the base of the monitor contains seven large rubber pads to prevent accidental sliding of the display. The panel itself slides into the base via a metal insert, but VESA wall-mounting options are available as well. In terms of design, the base provides an easy way to route cables out of sight and all connections are clearly labeled.
Pro Great color reproduction, reaches 100% of the sRGB spectrum
Thanks to the IPS panel ASUS has used in its MG24UQ, color reproduction is excellent. This monitor can display the full 100% sRGB color range -good for graphical editing. Without calibration, the MG24UQ is able to reach 78% of the AdobeRGB coverage. For comparison: an average monitor reaches about 76% of the AdobeRGB color spectrum. After calibration however, over 79% of the spectrum can be achieved and the average color accuracy delta E can also be reduced significantly from a little over 2 to 1.06 which results in an even better color reproduction. Anything less than 1 deltaE is imperceptible to the human eye. As a result, color accuracy is near perfect in practice.
sRGB is the color spectrum that is most commonly used on cameras and prints, and is also used for most images on the web. AdobeRGB however offers a wider color spectrum and as a result, more vibrant and lifelike colors.
Pro Extremely sharp
The MG24UQ uses a 4K-display with a resolution of 2160 x 3840 pixels, which is four times the amount of pixels of a Full HD display. This results in an extremely sharp image. The fact that the MG24UQ is relatively small further increases pixel density and thus sharpness. In terms of pixels per inch (ppi), the MG24UQ measures at 183 ppi. For comparison: a Full HD monitor of the same size would only reach half of that - 91 pixels per inch.
Pro Cinema-like picture quality for an affordable price
The fact that a monitor of this price range has a 5M:1 contrast ratio is simply astonishing. This means users get cinema-like picture quality right at their desk.
Pro Good sound quality with no need for external speakers
This monitor's speakers are as good as those found on small TVs. They're located in the back and come with an audio jack for headphone connectivity.
Pro Immersive
The 2560x1080 resolution creates an immersive setup. This applies even for work tasks: multiple documents can be displayed side-by-side with no legibility sacrifice. It's equivalent to having two monitors with 1280x1080 screens.
Pro Advantageous for all uses
This monitor's ultrawide screen has advantages for all uses. When it comes to movie watching or gaming, the screen size contributes to a truly engaging experience. As far as general productivity goes, the ultrawide screen makes it easy to have different applications or documents open side by side.
Pro Great for watching movies
The 21:9 aspect ratio comes in handy when watching movies. This is the default aspect ratio at which almost all of the films are shot. Hence, you can watch your movies without having two black bars at the top and bottom of the screen.
Cons
Con 4K resolution doesn't scale well with all software
Due to the native 4K resolution and the relatively small 28 inch screen size, text can be hard to read in Windows and other non-gaming environments, such as Adobe's software. Not everything scales well in 4K (yet).
Con Low maximum refresh rate of 60 Hz limits fast-paced action
Compared to some other gaming monitors, this ASUS display isn't as fast. The maximum refresh rate is limited at 60 Hz, which is the industry standard for all monitors. Some fast-paced games greatly benefit from a higher refresh rate such as 120 or 144 Hz as it increases fluidity.
Con Slower response time adds extra lag
The MG24UQ uses a panel with a response time of 4 ms, which is excellent for normal usage but less satisfactory for gaming. Some competitors offer a much quicker response time of 1 ms and are thus more ideal for fast paced action.
Con Limited connectivity
This monitor has two HMDI ports, which is pretty good. However, it misses other display inputs such as DVI or Display Port, making incompatible with older computers.
Con Lack of support for ultra-widescreen in (old) games
A handful of games do not support 21:9 aspect ratio by default. Some examples are Overwatch, Fallout 3, and Starcraft 2. If this is important for you, it is recommended you test this issue before getting this monitor. But there are solutions: you can either install fixes (only available for some games) or play in windowed mode, using a different aspect ratio.
Con Slow response time
A response time of 5 ms on a gaming monitor is pretty awful. Considering its refresh rate, it is understandable but not acceptable. Note that this response time is from gray-to-gray.
Con 720p and 1080p videos are sandwhiched
This monitor's aspect ratio means that many online videos, such as those from Netflix or YouTube, will have black spaces on the sides, which can be annoying.
