Ranked in these QuestionsQuestion Ranking
Pros
Pro Supports G-Sync
G-Sync eliminates stutter and screen tearing because it allows your monitor to synchronize its refresh rate to match the framerate of your video card.
The Acer XB271HU supports G-Sync in the 20-165 Hz range.
Pro Flicker-free
The Acer XB271HU doesn’t flicker because it uses a DC signal to dim its backlight. Such approach is beneficial as monitor flickering can cause eye strain.
Pro Adjustable stand
Adjusting the monitor to get the best possible viewing angle is not a problem with the Acer XB271HU.
Pro Decent responsiveness
The monitor offers lag-free gaming experience because of its fantastically low input lag of 4.6 ms, which makes it one of the most responsive gaming monitors in this price range.
Monitor's input lag is a delay between your video card producing a frame and the fame being fully processed by the monitor.
Pro Motion appears smooth
The Acer XB271HU has one of the best motion control toolsets in its price range, as it manages to display clear and flawless motion without even the slightest trace of motion blur or ghosting thanks to its excellent pixel response time, full ULBM support, and high native refresh rate.
The monitor naturally eliminates motion blur because its pixels need only one millisecond to change their color as the panel's full pixel response time is only 1 ms. Such rapid pixel transition keeps on-screen objects from leaving traces.
Acer's ULMB feature eliminates the artificial effect of ghosting as it strobes the monitor's backlight and makes it behave like a CRT display.
The motion looks smooth and fluid thanks to the monitor's high refresh rate of 165 Hz, which allows it to update its image up to 165 times every second.
Pro Good picture quality
The Acer XB271HU offers decent overall picture quality for a gaming monitor at this price point because its brightness, contrast ratio, and gamma response are all on par with what its competitors offer.
The Acer XB271HU displays adequately-looking images, with mediocre blacks, saturated mid-tones, and bright and vibrant colors. The dark scenes look average, with blacks that are neither too flat, nor too deep, because the monitor's contrast ratio is limited to 1000:1. Intermediate tones appear life-like, thanks to the monitors near-ideal gamma of 2.19. Colors look vivid as the monitor's panel can get quite luminous with its brightness peaking at 350 nits.
Additionally, the XB271HU can reproduce more saturated and sharper images than the 1080p competitors of the same size because it features 42% higher pixel density than a regular 27-inch FHD panel.
Pro Excellent for gaming
Armed with a 165 Hz TN panel, the Acer XB271HU offers decent overall picture quality and exceptionally responsive gaming experience, totally free of display lag or motion handling problems, which makes this monitor one of the best choices for gamers in this price range.
Pro Excellent value for money
Priced below $500, the Acer XB271HU offers a massive 27-inch QHD panel, full ULMB support, and G-Sync. You'll be hard-pressed to find a matching competitor for this monitor in this price range.
Pro Features a USB hub
You can use this monitor to charge external peripheral devices or connect them to your computer because the monitor has a USB 3.0 hub, which consists of four downstream USB ports and a single upstream port.
Pro Excellent screen uniformity
The AOC U2879VF has excellent screen uniformity, both in terms of luminance and color. In fact, this panel scores extremely well with a luminance deviation of 6.32 percent - which is better than most displays with IPS panels. No backlight bleeding or hotspots are present.
Pro Fast response time, great for gaming
With a response time of just 1ms, the AOC U2879VF is one of the fastest monitors on the market. Ideal for fast-paced gaming situations such as first person shooters.
Pro Thin bezel makes it ideal for multi-screen setups
The bezel of this display measures a thin 17 mm, which doesn't only result in a smaller build, but it makes the U2879VF also more suitable for multi-display setups.
Pro Support for MHL allows you to quickly connect a media device
This monitor supports MHL - short for Mobile High-Definition Link - which allows you to connect an Android smartphone or tablet to the U2879VF monitor.
Pro Excellent grayscales in sRGB preset, great for graphical work
When using the sRGB preset - which is particularly useful for graphical editing - the grayscale error readings of the U2879VF are quite low for a relatively inexpensive panel. The error measures was 0.93 Delta E - that's only a tad worse than specific graphical displays which retail for a much larger price. For comparison, a standard 28" TN panel measures at 1.60 Delta E. (Lower is better.)
Pro Extremely sharp
The AOC U2879VF 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 and overall great image quality. In terms of pixel density (measured in pixels per inch), this display measures at 163 ppi. For comparison - a Full HD display of the same size will only achieve half of that - 81.5 pixels per inch.
Pro Great value for the money
The AOC U2879VF is a cheap Ultra HD display with good image quality, the price/quality ratio of this display is quite high.
Cons
Con Complicated OSD
The Acer XB271HU has a very unintuitive on-screen display menu, which may cause a lot of confusion until you get used to it.
Con Power-on button gets stuck
The power-on button of this monitor sometimes gets stuck.
Con Requires a beefy computer
The Acer XB271HU produces noticeably higher strain on your graphics card than a regular FHD monitor because it has 42% more pixels. It could be a huge deal breaker for those with lower-end computers.
It is advised to research if your gaming rig will be able to deal with the extra pixels in your favorite titles if you go from an FHD monitor to a QHD one.
Con Disappointing input lag
The absolute input lag measured on this display is quite high at 87 ms. Although this won't disturb casual players, it's definitely not ideal for fast-paced gaming situations - despite a fast response time.
Con Maximum refresh rate limited to 75 Hz, less ideal for fast-paced action
The maximum supported refresh rate of this monitor is 75 Hz or 75 frames per second which is a tad faster than non-Freesync monitors, but is not as good as 120 or 144 Hz displays. Especially fast-paced games benefit from a higher refresh rate, for a more fluid gaming experience.
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 Red is slightly under-saturated
The display suffers from a slight under-saturation of the red color, which is a caveat for some graphical applications. This also can't be fixed through software, it's a hardware limitation of the panel.
Con Doesn't offer support for VESA mounts
The design of this display is proprietary and there is no support for the universal VESA standard. As a result, wall-mounting this display isn't possible, and alternative stands aren't compatible as well.
