Pros
Pro Thin bezels
The top and side bezels are about 13mm thin with the bottom bezel being slightly thicker at 18mm.
Pro Reasonably good luminance uniformity
The screen also has good luminance uniformity, providing a evenly lit picture. At the dimmest point, the deviation is 12% from the brightest point (141.4 cd/m² to 160.4 cd/m²).
Pro Low input lag
Complete input lag time (signal delay and pixel response time) is 7.4ms or under ½ of a frame.
Pro Easily adjustable
The monitor tilts (5° forward, 20° backward), swivels (60° to both the left and right), pivots (90° clockwise, allowing it to be used in portrait mode) and allows adjusting height between 43mm (1.69") to 410mm (16.14").
Pro Good contrast and brightness
According to tests performed by PC Monitors, PB279Q set to factory defaults (90% brightness, "Splendid" preset) produces luminance in the range of 0.24 - 282 cd/m² with a contrast of 1175. It provides both lots of brightness and reasonably dark blacks.
Pro Good color accuracy
The monitor covers all of sRGB space and represents the colors accurately.
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 A maximum refresh rate of 60Hz can be a concern for some
A 60Hz monitor, while sufficient for most people in most cases, can still cause issues with fast-moving objects on screen. It's especially important with things like gaming where the ability to react to events happening on the screen quickly is important.
Con Minor color temperature uniformity issues
According to Spyder4Elite tests performed by PC Monitor, PB279Q has color temperature issues that can be seen with the naked eye. A DeltaE deviation of over 3 can be easily noticed and the left side of the monitor deviates between 2.4 and 3.1.
Con AHVA glow
AHVA glow is the light on the sides or corners of the screen that can reduce some of the peripheral detail.
Con HDMI connections are limited to 30Hz
DisplayPort 1.2 (or MiniDP 1.2) is needed to run at 60Hz.
Con Unintuitive OSD
The OSD menu of the Acer XB271H is very unintuitive.
