Pros
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.
Pro Doesn’t put much pressure on a computer
Compared to the QHD monitors present in this price range, the Acer XB271H puts noticeably less strain on your computer because it has fewer pixels for your GPU to run.
Pro Has a USB 3.0 hub
You can charge external USB devices or connect them to your computer using four of the monitor's downstream USB 3.0 ports.
Pro Works without flickering
The backlight of this monitor doesn't flicker as the Acer XB271H uses a DC signal to dim its backlight. Backlight flickering is one of the main causes of eye fatigue while working with monitors.
Pro Ergonomic stand
Getting the best possible viewing angles is not a problem with this monitor because it supports the necessary ergonomic adjustments including tilt, swivel, height, and even pivot.
Pro Can be overclocked
You can increase the monitor's native refresh rate from 144 Hz to 170 Hz using the overclocking feature in the monitor's OSD menu.
Pro Lag-free
The Acer Predator XB271H has an amazingly low input lag of only 4.6 ms, which makes it one of the most responsive gaming monitors in its price range.
The input lag of a monitor shows how much time it needs to process a frame generated by a computer's graphics card.
Pro Handles motion very well
The Acer Predator XB271H makes the motion appear clear and free of artificial motion blur and ghosting effects, as the monitor combines fast full pixel response time with Acer's ULMB feature and the panel's high refresh rate.
Motion blur is eliminated as each panel's pixel can change its color fast enough to prevent the fast-moving objects from leaving traces. It is possible because of the monitor's full pixel response time of 1 ms.
Ghosting is reduced to a minimum by the aid of Acer's ULMB feature, which strobes the monitor's backlights and makes it behave like CRT monitors.
Finally, as the monitor's high native refresh rate ensures smooth and fluid motion by updating the monitor's image 144 times a second.
Pro Adequate picture quality
Even though the monitor's picture quality doesn't excel in any aspect, it still performs similarly to the majority of gaming monitors in this price range.
The monitor displays average-looking images with mediocre dark scenes and reasonably luminous colors. The dark scenes look average as the monitor's native contrast ratio of 1000:1 is not high enough to make its blacks appear natural. However, the colors look vivid thanks to the monitor's peak brightness of 300 nits.
Pro Supports G-Sync
G-Sync eliminates stutter and vertical screen tearing as it allows the monitor to synchronize its refresh rate to the framerate of your video card.
The Acer Predator XB271H supports G-Sync in the 20-170 Hz range.
Pro Great for gaming
The Acer Predator XB271H is one of the fastest gaming monitors in its price range; it offers responsive and lag-free gaming experience at a stunning 170 Hz refresh rate.
Cons
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.
Con Unintuitive OSD
The OSD menu of the Acer XB271H is very unintuitive.
