ASUS PB279Q vs Acer Predator XB271HU abmiprz

The top and side bezels are about 13mm thin with the bottom bezel being slightly thicker at 18mm.

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).

Complete input lag time (signal delay and pixel response time) is 7.4ms or under ½ of a frame.

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").

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.

The monitor covers all of sRGB space and represents the colors accurately.

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.

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.

Adjusting the monitor to get the best possible viewing angle is not a problem with the Acer XB271HU.

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.

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.

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.

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.

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.

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.
