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.
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.
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.
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.
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.
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.
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.
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.
With a response time of just 1ms, the Acer GN246HL is one of the fastest monitors on the market. Ideal for fast-paced gaming situations such as first person shooters.
The Acer GN246HL features a very fast refresh rate of 144Hz (144 times per second). This allows for extremely fluent gameplay and is a major improvement over regular 60Hz displays.
The monitor does not have a DisplayPort connection, which means some of DisplayPort's advantages over other connection types such as adaptive scaling can't be used.
This monitor's contrast ratio makes it capable of a very vibrant and natural color reproduction. It comes with presets optimized for several use cases, such as gaming, movies, or text editing.
Dual speakers located at the back of the monitor offer a decent-quality stereo sound output. There's also an audio jack for headphone/external speakers use.
This monitor is missing a DVI-D port, which can be circumvented by using a HMDI to DVI converter. Precisely because of this, ASUS ships the monitor with such an adapter.
With a screen size of 27", a good resolution would be expected. Sadly, this is not the case. When this monitor was launched, 4K still wasn't popular. It's not a great device for playing 1080p videos, but if you're not going to give it this kind of use, this resolution shouldn't be a big issue.
The monitor screen curves conveniently to support the elliptical field of view of humans. This noticeably reduces the stress on the eyes with prolonged usage.
It's impressive that there's a monitor with a contrast ratio of 3000:1 at this affordable price. In this case, the higher, the better, and this ratio is above those found on similarly priced monitors.
Having a setup that uses several of theses screens is quite awkward, since overall they would curving in and out. In most cases, you would be better of buying flat-screen monitors, which contribute more naturally to an overall sphericity of a multiscreen setup.
This monitor only supports AMD's FreeSync technology, and not the equivalent nVidia G-Sync technology. Both are adaptive synchronization technologies that enable smoother frame transition, eliminating screen tearing.
In-Plane switching technology replaces the standard TFT technology, provides significantly improved viewing angles and does not tail or distort when touched (not that you should be touching your monitor).
