Acer XB271HU

Update: Acer has just informed me that this monitor will be able to reach a whopping 165Hz with NVIDIA G-SYNC technology enabled.

Acer has very recently released a press release regarding four new monitors, which are all a part of the Acer Predator series and the last three are more precisely part of the new Acer Predator XB1 series.

  • Acer Predator Z35
  • Acer Predator XB281HK
  • Acer Predator XB271HK
  • Acer Predator XB271HU

The Predator XB1 series gaming monitors are all basically newer models of gaming monitors that are already out there and have been released for many months now. The Acer Predator XB271HU is a newer model of the Acer Predator XB270HU, which is on our gaming monitor buying guide, and spec-wise, they are almost the same. Once the release is nearing, we’ll try to test this particular monitor and compare it with the Predator XB270HU.

It will also be interesting to see how well this monitor compares with the very similar ASUS PG279Q, which was released in November 2015. Both displays are capable of reaching 165Hz with NVIDIA G-SYNC as well.

The XB271HU is a 27-inch gaming monitor with a 2560×1440 resolution, also called WQHD. The panel is an IPS-type, which offers superior colors and the best viewing angles. As for refresh rate, this monitor has a maximum static refresh rate of 144Hz, but with the NVIDIA G-SYNC technology enabled, it can reach 165. The minimum refresh rate with G-SYNC is 30Hz, making the G-SYNC range 30Hz-165Hz. Notice the ultra-thin bezel (zero-frame), which is a significant difference from the older XB270HU model.

Response time on the XB271HU is 4ms (GtG), brightness is 350 Nit (cd/m2) and the contrast ratio is 1000:1. It can produce up to 16.7 colors (8-bit, most likely 6-bit+FRC to emulate 8-bit) and features two 2W in-built speakers. It also covers 100% of the sRGB color gamut, just like the two other XB1 series gaming monitors.

It will be interesting to see how well this new Acer Predator gaming monitor compares with its older model. The release date for the Acer XB271HU is in November and pricing will be revealed closer to launch date along with detailed specs.

We have now tested this monitor and find it to be the best gaming monitor for the money right now.

    This panel is a native 8-bit panel. There is no indication that it uses 6-bit + FRC. Most if not all IPS monitors are 8-bit, with the exception of eIPS which is now pretty much extinct.

  • Sentey

    will it be cheaper than the pg279q?

  • They should be around the same price that the older versions are now – around $700.

  • David Selby

    Any idea on release date? Tried two pg27’s and they had terrible qaulity control!

  • Khan

    Acer has it listed on our Australian website for AU$1299 (about $900 USD).

    Really hope this is not the final pricing.

  • Tyrann

    How much? I’ll buy at $600

  • Make it 30″ for this price and I’ll take 3.

  • TristanSDX

    Precise color requires more time for crystal to rotate / move. So 6 bit will be always faster than 8 bit, and 8 bit will be faster than 10 bit. For 165 Hz they probably reduced precision.

  • yasamoka

    Look up the panel specs. It’s an 8-bit panel. Nothing new here, AU Optronics has been knocking out IPS panels that are fast enough to refresh at 120Hz+ while still being 8-bit.

  • King_Bob

    This better support 3d vision , the last 1 didn’t, so i never bought it.

  • Iluv2raceit

    The XB271HU does not support 3D, sorry 🙁 It has to do with the pixel draw lag. 3D Vision requires a very short pixel draw time, so for now, no IPS panel can support Nvidia 3DVision. The short pixel draw time is required due to how the way the screen has to flash alternate frames in order to support the active shutter glasses (left eye, then right eye) that are used for Nvidia’s 3D Vision. There used to be TVs that also supported active shutter glasses for 3D, but were not compatible with Nvidia’s 3D vision.

    MSRP is $799 O.O

  • Iluv2raceit

    No, same price. MSRP for both monitors is set at $799. However, Newegg was selling open box PG279Q monitors for $639 last week. As you can imagine, they sold out quickly. I bought an open box unit last week, but ended up returning it yesterday due to excessive backlight bleed in the upper right corner as well as unusually high IPS glow on the entire panel. I also bought an Acer XB271HU and got it yesterday. I tested it out and the panel was noticeably better in quality versus the panel of the Asus PG279Q unit I returned. I am keeping the XB271HU and will be selling my ‘old’ XB270HU 😉

  • Iluv2raceit

    No, $799 is the MSRP for both the PG279Q and the XB271HU…in the US anyway. Not sure about prices overseas though…

  • Iluv2raceit

    The XB271HU is a true 8-bit IPS panel. I was even surprised to see “IPS In Plane Switching” printed on the lower left corner of the panel bezel. I had thought “IPS” was a patented name by LG, which leads me to believe that this panel may not be an AUO AHVA panel afterall. That would definitely explain the much lower defect rate vs. the Asus PG279Q panel. I could be wrong, which means one of three things: 1) Acer could get into trouble by having “IPS” printed right on their monitor, 2) it really is an LG panel and not an AOU panel, or 3) they received permission from LG to do use the “IPS” description. Just some food for thought 😉

  • Tyrann

    Sucks, i’ll just wait till next year.

  • Iluv2raceit

    Sure, but then the next best thing will be out for $799 or more…lol

  • Iluv2raceit

    Yup, Australia Acer always seems to have a higher MSRP vs. other countries. It might have to do with the fact that shipping cost to Australia is higher than the norm due to the geographically separated location (and distance).

  • Iluv2raceit

    This will no longer be true when OLED monitors arrive. Response times are near 0ms, refresh rates over 1000Hz (future PMOLED type panels), and contrast ratios well over 100 million to 1 with no dynamic processing required. Also, there will be no backlight bleed or IPS glow because OLED monitors do not use a backlight. Each pixel is self illuminated and can represent full 10-bit color (1.1 billion colors). Unfortunately, cost will be a lot more prohibitive than even the highest end gaming monitors today.

  • Iluv2raceit

    Actually, AU Optronics uses what is called Advanced Hyper-Viewing Angle (AHVA) panels, which are their own invention. IPS panels were developed and patented by LG. Both technologies are similar in specifications overall, with the advantage going to AHVA panels when it comes to response times and higher refresh rates. Unfortunately, the trade off comes with a higher amount of IPS glow. The backlight bleed issues are caused more by low quality control at the factories in China, and not a direct result of the differences in the panel technology.

  • Beale Denver

    It has absolutly nothing to do with input lag, a too slow display time will cause blurring also know as positive ghosting but input lag is something entirely different and has no effect at all on motion clarity. The interface has to be built to include 3d vision. The effective rémanence and motion clarity on theses screens is as good as many other 3d vision compatible, it is just to cut costs in development for an unused feature that it is not included. Nothing to do with hardware limitations, just money. I find it quite amazing how some people can simple state random stuff as fact without including any form of hesitation or doupt, in this case it is likely just vocabulary confusion. (forgive my english, the correcter is stuck in french…)

  • Iluv2raceit

    Didn’t mean input lag. My post has been corrected. And don’t listen to Random Digits. He’s an idiot and didn’t do his research. He has no idea of the difference between active and passive 3D technology.

  • Random Digits

    There have been IPS screen’d TV’s and monitors that DO have 3D, for a while now. So lluv’s comment is mute, right there.

    Like Beale said: don’t summon hearsay. It brings the naysayers out of the woodwork.

  • Random Digits

    Considering I bought my first 2707 Dell Ultrasharp for $1200, i’d say they have come down quite a bit in nominal pricing structure.

  • Iluv2raceit

    You have it all wrong. Nvidia 3D vision uses active shutter glasses which involves the alternating blacking out (left, right, left, right, etc) of the lenses of the glasses. TVs use polarized ‘passive’ method to emulate 3D. So you see, I was right and you were way wrong.

  • Random Digits

    Did you see me quote using nVidia 3D Vision? Nope.

  • John Fak

    You pulled those numbers out of your ass. While in theory OLED should be able to go pretty high, all the OLED panels that came out so far have been in line with the other panels, no extraordinary response time or frequency.
    Contrast is better, but not 1 to 100 million like you said.

  • Iluv2raceit

    Hate and troll all you want. For example, OLED TVs have an average ~0.001ms pixel response times. Motion blur was non-existent in OLED TVs compared to the easily distinguished motion blur in conventional LED TVs:

  • Iluv2raceit

    Nice trying to get out of being wrong. Not going to work. I win.

  • Random Digits

    You couldn’t win for losing.

  • John Fak

    That is a theoretical article, link to a real product, you moron.

  • Iluv2raceit

    But you can lose for being a loser.

  • Iluv2raceit

    You are an idiot. Learn how to read.

  • OwlsPredict_OraclesStandGuard

    Quit being a d-bag. Everything he said about OLED is true you negative nancy. He didn’t say: “I can buy that OLED monitor right now.” So crawl back in your miserable cave/hole and wither away.
    ; )

  • ☠▄█Zac█▄☠

    This is almost a 30 day old post… Maybe you should research before you talk. You just made yourself look like a huge retarded AHole and a troll.

  • Benson

    lluv2raceit u were way wrong too. most samsung tvs use active shutter 3d and mainly LG use passive 3d.

  • Benson

    apart from the no backlight OLED isint a big deal they have been using them in phones since samsung galaxy S2 nearly 5 years ago and it hasent been blowing peoples minds compared to HTCs one series that use IPS have equally as good colours/contrasts. if anything the samsung oled phone displays have a fake color look to it.

  • TodayWeLieQuestionMark

    Does anybody know the panel that is used inside of this?

  • James F


  • TodayWeLieQuestionMark

    Congrats, you know the panel technology…I asked for the panel. Which exact one. LG? Auo? Samsung? Model number?

  • Sty

    Pretty sure it’s AUO IPS-Type.

  • davidintel

    This monitor is $549.99 today at Best Buy

  • MC_bot

    Did LG buy Hitachi? The original IPS patents were Fraunhofer/Merck with the follow ups all held by Hitachi, not LG.

  • Iluv2raceit

    Not sure, but good question!
