The Acer Predator XB271HU is an excellent 27-inch QHD gaming monitor that offers multiple neat gaming features such as Nvidia's G-Sync. This monitor is equipped with a fairly responsive and flicker-free TN 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 from display lag or motion handling problems, which makes this monitor one of the best choices for gamers in this price range.
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 adequate-looking images, with mediocre blacks, saturated mid-tones, 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 its 1080p competitors of the same size because it features 42% higher pixel density than a regular 27-inch FHD panel.
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 objects on-screen 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 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.
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.
