Acer XR341CK 34-Inch Curved FreeSync Monitor Review

Acer offers its latest curved monitor, the XR341CK 34-inch WQHD, which should appeal to gamers with its 75Hz IPS panel and FreeSync. Today we check it out.

Grayscale Tracking And Gamma Response

Our grayscale and gamma tests are described in detail here.

You can see that the XR341CK is nearly perfect out of the box. The chart shows a slight rise in blue as brightness increases, but all the errors are below two DeltaE, which means they cannot be seen. Considering Acer doesn't include a factory-certified calibration, this is an impressive result.

Switching to sRGB mode locks out all adjustments including Brightess and Contrast. It's still very accurate as far as grayscale tracking is concerned. Its only flaw is gamma, which we'll show you below.

Calibration does little to improve an already superb test result. The only change we made was to increase Red Gain by one click and lower Contrast by two. Only a few professional displays can do better than this.

Here is our comparison group.

The U3415W remains our out-of-box champ in the grayscale tracking test. But the fact that a gaming monitor is only a tick behind speaks volumes. Acer is using a very high-quality LG panel part in the XR341CK and it shows.

If you lined up all our test subjects together, you wouldn't see a difference in their grayscale accuracy. The fact that four of the screens are gaming monitors tells you just how good the latest displays are. It really can't get much better.

Gamma Response

Out-of-box gamma is the only flaw in an otherwise superb set of test results. Tracking is fairly solid but the offset is a little light. It's a small difference but a visible one. Luckily all you have to do is change the preset from 2.2 to 2.4.

This is much better and it would be perfect if not for a tiny error of 1.8cd/m2 at 90 percent. It's well below the visible threshold and again we're seeing a pro-level result.

Gamma tracking is super-tight except for the tiny dip at 90 percent shown above. The XR341CK is still among the best in this test.

We calculate gamma deviation by simply expressing the difference from 2.2 as a percentage.

The average gamma value is 2.19, which is only .04 percent off the 2.2 standard. Just remember to change the preset in the OSD to 2.4 to see the same result.

    Why do they make screens brighter than 300 or let`s say max 350 cd/m² ? I had tested a Iiyama 27" with 350 and at max brightness i could feel the heat from the screen on my hands and face at 30 cm away from the screen ... you can`t even use the blessed thing at max.. i finally settled for around 20-30% of screen brightness max 50% for presentation purposes ...

    Better the screen is too bright and brightness can be reduced than it being too dark and brightness cannot be increased. Nothing to complain about in my opinion.

    Seriously considering two of these for work/play, but holding off as the Asus ROG PG384Q 34" curved monitor looks more promising, G-sync, IPS, and 3440x1440 @ 100Hz. All come down to when Asus will release it, and how long I can wait...

    acer also has a g-sync model (XR341CKA aka Predator X34), but, like asus, there seems to be a never ending delay after delay.

    I saw a similar monitor in the store recently and i have to say yes it is wide, but in height the display is too short, they need to add a few more inches to height so the experience is very immersive.

    Great Review guys. Just one thing, you need to remove the reference to being a Predator monitor, this monitor has absolutely no tie to the Predator line-up of products, it is a XR Series monitor. Only the G-Sync version falls under the Predator series.

    $1000? LOL No. They have already proven in the TV market that this curved crap adds nothing to the experience, and even detracts from it. It is not worth any type of premium whatsoever.

    $500, Yes

    You can't just add to the height or the aspect ratio wouldn't be 21:9. The height is equal to a 27" 16:9 monitor with 30% more width.

    You're looking for a monitor with 3820x1600, essentially a 4k monitor with the vertical chopped off.

    What GPU are you running? if you have AMD get this, if you have Nvidia get the ROG...but wait for however long it will take.

    Why should someone wait for the ROG, they will be using the exact same panel and the Acer X34 has already passed both reviews I've seen so far with flying colors. The only difference is if you desperately want the slightly different aesthetic of the ASUS version over the Predator.

    The X34 should be out in a couple weeks...the ASUS won't be out until possibly Jan 2016.
