Acer on Wednesday introduced its new Ultra-HD gaming monitor with an up to 144 Hz dynamic refresh rate enabled by NVIDIA’s G-Sync. The Predator XB273K is aimed at serious gamers looking for both high resolution as well as fast refresh rates. Meanwhile, the new unit is considerably cheaper than Acer’s top-of-the-range Predator X27.

The Acer Predator XB273K is based on an IPS-type panel featuring a 4K (3840×2160) resolution, with up to 400 nits peak brightness in HDR mode (the lowest DisplayHDR certification). The refresh rate goes up to 144 Hz, and is dynamic via the support of Nvidia's G-Sync. The panel has wide 178°/178° horizontal/vertical viewing angles thanks to its IPS panel. Acer yet has to disclose other specs of the LCD, but it already looks like the Predator XB273K resembles the company’s flagship Predator X27 display, but lacks FALD (Full array local dimming), quantum dot-enhanced backlighting, and NVIDIA’s G-Sync HDR.

If it is indeed the case that the XB273K is based on the same AU Optronics’ M270QAN02.2 AHVA panel (Which is currently the industry’s only 4Kp144 panel), then it is reasonable to expect it to feature a 4 ms response time, along with some other peculiarities of said panel.

Despite the fact that the Predator XB273K lacks quantum dots, it still supports a wider-than-sRGB color gamut. Acer says that the monitor can cover 90% of the DCI-P3 color range and naturally 100% of the sRGB palette. To further maximize color accuracy and reduce reflections, Acer’s Predator XB273K will come with a light-shielding hood, just like its more expensive Predator X27 brother.

By launching the Predator XB273K, Acer makes 4Kp144 G-Sync gaming slightly more accessible. Meanwhile, it should be kept in mind that to take full advantage of such monitors, gamers are going to need an NVIDIA GeForce GTX 10-series (or newer) graphics card with a DisplayPort 1.4 output and a fresh VBIOS. Bandwidth requirements of 4Kp144 8-bit monitors exceed what DisplayPort can deliver today; therefore, to stay within the bandwidth limits of the interface, the displays will either be limited to a 120 Hz refresh rate with full 4:4:4 chroma subsampling, or use 4:2:2 subsampling to get to 144Hz+. Speaking of connectivity in general, it is natural to expect the Predator XB273K to have at least one DisplayPort 1.4 input as well as one HDMI header for compatibility. Additionally, the monitor also has a quad-port USB 3.0 hub.

UPDATE 8/30: Correcting bandwidth requirements.

Acer’s Predator XB273K will hit the North American market in the fourth quarter, in time for holiday season. In the U.S., the LCD will cost $1,299, whereas in Europe it is going to carry a €1,499 ($1,749 tax included) price tag.

    Anybody knows if 32" version is also coming? Reply

    That's what I'm waiting for too! Sometime next year. Reply

    According to TFT Central, early next year for panel production from AUO to start, mid 2019 before the first shipping products are available.

    Unfortunately neither LG or Samsung are currently planning on making similar panels. (Both companies are known for significantly better quality control than AUO.)

    Acer and Asus pretty much abandoned it. The reason is pretty simple, its already hard to keep up with low size versions making the panel proved to expensive. You think the $2000 one was expensive, that would easily put it close to $3k mark. Of course they still might make it, but from all the people i've talked to cause i was very interested in it as well, they are not making it at this time.

    They do have some out in the wild, but i think those are sample models.

    Maybe the FALD version, but I didn't hear they abandoned the normal 32 inch 4k 120hz ones. Reply

    Going through newegg review, this monitor has fan. Did not expect that:

    Pros: 4k HDR panel, high refresh rate, 1000 NITS

    Cons: Poor quality control. 8+ dead pixels on my panel. Speakers distort at moderate volume. Fan never turns off even when the monitor is power off. Sent it for repairs 3 weeks ago, still waiting on a fix.

    Other Thoughts: I would avoid the panel given the quality issues and if you need a repair prepare to be without your monitor for 21+ days.

    1 NITS = 1 cd/m2
    So it's not 1000 NITS, it's 400

    I'm guessing it's using the same huge FPGA to do Gsync as its FALD sibling, and that chip sucks too much power to passively cool in a reasonable sized package. Reply

    Those fake 144Hz 4k monitors, why not simply advertise them as 4k 98Hz?

    Moronic gamers seems to like playing youtube quality real time games xD.
