Ranked in these QuestionsQuestion Ranking
Pros
Pro Very good viewing angles
With 178 degrees of both vertical and horizontal viewing angles, this monitor can be used at an angle with no problems, and if watching media with other people they will still see a clear picture even if they are viewing it off-angle.
Pro Fast response time means no display lag
With only 5ms of response time, this monitor will display images nearly instantly after they are received. This is important, especially for touchscreens where a delay in touch input and the displayed image moving would be very noticeable. 5ms is also considered good enough even for high level gaming, although world-wide top players will prefer even lower response times.
Pro Interesting black and white design is unique
The white glossy base and rear of this monitor may not suit everybody, but it certainly gives it some personality which sets it apart from other monitors. The contrasting colors can look sharp in many setups, although not all of them.
Pro Decent black levels, good contrast ratio
The black levels are respectively low at 0.16cd/m², which helps the contrast ratio achieve 1100:1 which is much lower than the advertised 5000:1, but still quite good.
Pro Pretty fast response times make the system feel quick
The response time is 12ms, which isn't lightning fast, but it's still quick enough to make the system feel more responsive than cheaper monitors. While not fast enough for high-level gaming, this monitor won't make your system feel slow or unresponsive.
Pro 'Massive tablet' design is unique, and versitile
It really does look like a massive tablet with a kickstand - but that's not a bad thing. There's no stand visible, leaving the front looking very clean. The stand can angle anywhere from 15-70 degrees which allows for flexible use, or it can be folded in and used flat on the desk or even mounted using the VESA mounting holes.
Pro Built-in speakers, webcam, and mic
This monitor has many peripherals built-in, and unless you use them heavily they will do the job just fine. Unless you feel the need for dedicated hardware, the built-in stereo speakers work well enough, and the webcam and mic are acceptable quality for occasional recreational use (for business calls or other uses where quality is important, you'll want to upgrade to dedicated hardware).
Cons
Con No USB ports
While many other monitors in this price range offer USB pass through as an added feature, this one lacks any extra USB ports. You can't plug in any mice, keyboards, or external hard drives into this monitor.
Con Sub-par display quality
Colors are somewhat accurate, as this monitor scored 86.8% of the sRGB color gamut...however when compared to other IPS panels which typically score 95% or higher this is a disappointing result (after calibration it still fell short at around 91%).
Black levels are measured at 0.32cd/m² which means that when pure black is displayed on the screen, they will appear gray-ish instead of a true black. This leads to a lower than advertised contrast ratio of 519:1 (it is advertised at 1000:1), which isn't impressive at all.
Con Limited adjustment doesn't allow full range of movement
The stand allows for 30 degrees of tilt, which is more than adequate for traditional monitors - however this is sub-par for touchscreen monitors. Touchscreen monitors benefit from tilt adjustments more than traditional monitors, as different uses work best at different angles. For example, watching a movie or web browsing is best done in a near-vertical position, while typing on an on-screen keyboard is most comfortable at a large angle which can't be achieved with this monitor.
There also is no swivel, pivot, or height adjustment.
Con Disappointing color accuracy
The MVA panel (multi-domain vertical alignment: in-between of TN and IPS technologies) doesn't reproduce colors very accurately. It scores just 82% of the sRGB color gamut, while other panels offer high 80s and even above 90%. This display's weakest points are with the green and cyan shades, while reds and blues appeared just fine.
Con Dim display
The display doesn't get very bright - at just 172cd/m² this panel is very dim. Many monitors can achieve 300cd/m² or higher brightnesses.
Con Takes much more power than similar monitors
Without using the ECO mode, this monitor requires about 50 watts to power it. This is double than other monitors. There are different levels of ECO modes, however these dim the display and barely get down to the power level of other monitors when they are all enabled.
