Acer XB280HK: Introduction, Design and Specs

When it comes to gaming, 4K displays present a conundrum (beyond 4K being used incorrectly, but I’ll still use it). On the one hand, all the extra pixels allow for far more detail. On the other, that is a lot of pixels to push for a GPU. Even with the best GPUs out there, you might – okay, will – have to disable certain features and start to introduce aliasing and other artifacts. A solution to this might be G-SYNC to enable gaming that looks smooth even when running below 60 FPS, and that's what we're looking at today.

G-SYNC, only available on video cards from NVIDIA, allows frame rates below the normal optimal speed of 60FPS to still look very smooth. The Acer XB280HK is the first G-SYNC display to also feature a 3840x2160 resolution. Unlike some other G-SYNC displays the Acer only runs at 60Hz and below, though I don’t believe running faster than 60Hz at 4K resolutions will be much of an issue right now. Anand previously reviewed G-SYNC and described the details of how it works.

Like all currently shipping G-SYNC displays (with the exception of the IPS Acer display announced at CES 2015), the Acer uses a TN-panel. For 120Hz or 144Hz G-SYNC panels you often need to use TN, but 60Hz would allow for IPS. The likely culprit here is cost, as the Acer currently sells for under $800. Other 4K 28” IPS displays cost at least as much and lack G-SYNC, making them a much worse choice for gaming than the Acer. Since I am not a gamer myself, all the gaming comments for this review will be done by Jarred Walton. Aside from some WiiU or Magic Online, my gaming days are well behind me (or ahead of me).

Like most G-SYNC displays, the Acer has but a single DisplayPort input. G-SYNC only works with DisplayPort, and if you didn’t care about G-SYNC you would have bought a different monitor. It also has a USB 3.0 hub with two ports on the rear-bottom and two on the side. There are no headphone connections or speakers, so it is fairly bare-bones as far as connections and extra features go.

The included stand is very good overall. Built-in adjustments for height, tilt, swivel and pivot make it a very flexible option, and though running a TN panel in portrait mode can be problematic at best, the ability to pivot does provide for easier access to the bottom ports when connecting peripherals. It also has 100mm VESA mounting holes if you desire to use another stand or even wall mount it. The outer bezel is a shiny plastic, which is not my favorite as it shows fingerprints and smudges very easily. Though an $800 monitor should have a nice stand, many displays choose form over function but Acer does it correctly here. I really see no reason to replace the stand they provide.

The OSD works well, with a row of buttons on the bottom of the screen and icons directly above them indicating what they do. There's no guessing which is correct, and no touch-sensitive buttons that don’t work well. Acer provides basic, simple, effective controls that everyone should be happy with. There are a decent number of controls available, including gamma and color temperature. There is also an optional frame rate indicator that you can see on the left side of the screen. This gives you a quick indication of what your actual frame rate is, since G-SYNC should remain smooth even when it drops below 60Hz.

From a user interface perspective, the Acer XB280HK hits all the right notes. The stand is very adjustable while the controls are easy to use. The only real thing I would change is to make the bezel a matte finish instead of glossy to avoid fingerprints, and because I think it just looks better.

Looking just at the specs and the exterior design, the Acer XB280HK has a lot going for it. The big questions are how well will it perform when gaming at 4K with G-Sync, and how does the monitor perform on our objective bench tests?

    This is why I ended up with a 21:9, 3440x1440 monitor. It's more expensive, but you can run with 100% scaling, and use 1440p resolution for games that don't support 21:9. I can also hit 60fps easily with GTX 980 SLI with all options maxed. No G-Sync, but I don't like being locked into a GPU vendor when I only replace my monitor every 5 years or so.

    Also looking into the 3440x1440 spectrum. Out of curiosity, which monitor did you go with?
  • Mondozai - Wednesday, January 28, 2015 - link

    Acer is coming out with a 34" 144 Hz ultra-wide 1440p monitor with G-Sync. So that could be an alternative.
  • Mondozai - Wednesday, January 28, 2015 - link

    Oh and LG have their 34UM67 model, a Freesync IPS 1440p ultrawide 34" monitor. It's going to cost about 500 dollars or so, so the prices are coming down fast.
  • JarredWalton - Wednesday, January 28, 2015 - link

    $500 -- you have a source for that? If they get IPS 3440x1440 34" for that price, I'll be extremely surprised. After all, their non-FreeSync option currently costs over $900:

    Need to jump in and say there are zero confirmed 3440x1440 Freesync of Gsync monitors. There are rumors, but that is all.

    Right now, the best 3440x1440 appear to be the curved Dell and LG, but I'm also waiting to read more testing of the AOC non-curved and the Samsung curved.

    AMD had an LG at CES... however I think it may have been 2560x1080.
  • jackstar7 - Wednesday, January 28, 2015 - link

    Indeed it was only 1080.

    People are taking a couple "stories" about new models where the authors are writing that they "believe" the monitors will have 3440x1440 and running with that "belief". Facts are thus far not present.

    Unless something's changed in the last few days, there's no official confirmation of the 34UM67 being 1440p.

    To the contrary, given that the 34UM65 is *1080p* (while the 34UM95 & 34UM97 are 1440p), unfortunately there's good reason to believe that the 34UM67 will be 1080p Freesync.
  • Black Obsidian - Thursday, January 29, 2015 - link

    Oh, and if the 34UM67 is indeed 1080p, that would make a ~$500 price tag more reasonable. The 34UM9x 1440p parts are still north of $900, but the 1080p 34UM65 can regularly be found much closer to that $500 mark.
