Acer Predator XB1 (XB271HU) WQHD 144 Hz Monitor

There sure aren’t a whole lot of options on the market for WQHD (2560 x 1440) 144 Hz monitors, and even less options when you’re looking for an IPS display panel.  Heck, you don’t have a lot of options for WQHD 144 Hz TN panels, either, especially when looking for 27-inches or larger.  Today we’re going to take a look at the Acer Predator XB1 (XB271HU), which is a 27-inch WQHD panel capable of a 144 Hz refresh rate, or 165 Hz when overclocked, and 4ms gray-to-gray pixel response times, featuring NVIDIA G-SYNC technology.  Some other features include 100% sRGB color gamut, a brightness of 350 nits, and built-in 2 watt stereo speakers.  This monitor has been available since November 2015, but has been well received by gamers.

Carrying a pretty hefty price tag, you can currently grab this monitor for $724.99 shipped on Amazon.  If you’re not needing or wanting G-SYNC, you can get the AMD FreeSync counterpart, the XG270HU can be had for $427.95 shipped on Amazon currently, or $297.04 cheaper than the XB271HU that we’re reviewing today.  The other biggest differences between the two would be TN vs. IPS, and 1ms vs. 4ms gray-to-gray response times – respectively.  Acer provides you a 3-year warranty on this monitor, should you have any troubles with it.

Like the Acer Predator X34 that we reviewed previously, the Predator XB1 also looks very sexy with its extremely thin bezels.  You’ll find that this 27-inch panel measures (W x H) 24.0625 (1/16) x 14.6075 (7/16) inches (61.11875 cm x 36.67125 cm) , which actually isn’t all that big thanks to those thin bezels.  This is not a light monitor, with a weight of just over 17 pounds, but it feels nice and sturdy with its well-built aluminum stand.

The packaging for the XB271HU is extremely colorful but lacks any details.  Opening up the box we find the monitor is protected very well with formed Styrofoam.  The stand is broken down into two pieces, but is easily assembled with a thumb screw.

Taking a look at the monitor itself from the front, you can’t help but notice the incredibly thin bezels.  A mere 2mm protects the outer edge.  On the bottom bezel, you will see the Predator name.  Hidden away is a pair of 2-watt speakers, and while they’re not very powerful nor do they sound that great, they will at least get you a little bit of sound.  Obviously the better choice for sound here will be a headset or dedicated speakers.

On the bottom right corner we find the on-screen display (OSD) buttons.  The power button will have a somewhat harsh blue LED next to it when the display is in use, amber when in standby, but fortunately you can turn this off or dim it within the OSD.  In my experience with using the monitor in a dimly lit room, it was not too bothersome, but I know many folks that would shun this LED.

Flipping to the backside, we find a matte finish on the back cover along with the only Acer logo that you will find.

On the rear, going left to right, we will find Kensington lock spot, a power switch, and power input.

Acer Predator XB271HU - Ports

Sliding over a bit we find a two whole inputs – DisplayPort 1.2, HDMI 1.4, a headphone output, as well as 2x USB 3.0, and the USB 3.0 (upstream) hub connector.  Here we will need to use the DisplayPort input if we want to take advantage of anything over 60Hz; The HDMI port will be limited to 60Hz.

Acer Predator XB271HU - Ports

On the left side of the panel (when viewed from the front), we find two more USB 3.0 ports, with the top one being a powered port, dedicated to charging mobile devices.

Reading around online, I noticed many folks that were claiming the accents on the stand were orange and that they highly disliked it.  Rest assured, the accent color is actually red and it looks very nice on this monitor.  To me it is a subtle accent and is not distracting at all, as your eye will be totally drawn by the bright and colorful output from the panel.

Acer Predator XB1 - Stand

With the panel attached to the base, and in a landscape configuration, the Predator XB271HU stands 21.5 inches tall at the highest, and will go down to 15.5 inches.  With the panel slid all the way down, the base will actually be higher than the panel itself, which measures 17 inches high.  In portrait configuration, you’ll find this monitor 26.5 inches at its tallest and 24.5 inches at its shortest.  You can tilt the panel from -5 degrees to +35 degrees for your ergonomic needs.  The stand itself is very deep and measures approximately 11 inches deep.  Fortunately it’s flat and you can overhang a bit of the rear off your desk if needed (I had to), or if you need you can VESA mount this monitor.

    dont ever think amd gpu if u want joy and have fun with high games and high screens.

    amd for budget and lower quality user.
    nvidia for high value gaming,high fps and smooth fps

    wich one u belong…

  • Wookie Groomer

    XB1? What were they thinking? They want to sell this thing or not?

  • CeyeN

    For almost 300$ less, i think people should go for the Free sync variant. and buy a AMD card with the saved money to go along with it.

    • 1rishPredator

      That’s what I did. I bought mine for $475 AUD on sale and I love this monitor. It’s true what they say, there is no going back to 1080p60hz after 1440p144hz that’s for sure.

      They need a Freesync IPS variant to this. It’s the G-sync board that adds the extra cost.

      • Yar Nunya

        Gsync is only part of the cost, TN is significantly cheaper to produce than IPS.

        • 1rishPredator

          Yes, that too. G-sync + IPS is why it’s much more $$$.

    • kamilus

      AMD is out of competition now. There is nothing similar to GTX1080. ANd even shitty RX 480 is loud comparing to much more powerful GTX1080.

    • Monitorm

      There is no AMD card yet to even match the performance of a GTX1070, a RX480 is a little under-powered for 1440P, not a optimal match, regrettably a cheaper but worse option.

    • Daniel Czyz

      Thats a bad comparison on the article. It should be a Freesync IPS Panel and not TN. Something like Asus MG279Q

    • Lazerbeak

      still true unfortunately though if you knock some settings down a rx580 would probably do “OK”
