The Acer Nitro XV340CK is a great ultrawide gaming monitor. It delivers a great gaming experience that feels smooth and responsive thanks to its low input lag and high refresh rate. Its excellent response time makes fast-moving content look crisp, and it has an optional Black Frame Insertion feature to improve motion clarity further. FreeSync is supported natively to help minimize screen tearing, and it's compatible with NVIDIA's G-SYNC. Its ultrawide format provides plenty of screen space for multitasking, and it even has a Picture-in-Picture mode that lets you display two input sources at once. Unfortunately, it doesn't get very bright, so visibility can be an issue in well-lit rooms. Also, while it has HDR support, it can't display a wide color gamut, resulting in a lackluster HDR experience.
The Acer Nitro XV340CK is a good monitor overall. Although it's primarily designed for gaming, it's versatile enough to make it a good option for office use and media consumption. Its large screen provides plenty of screen real estate for multitasking and delivers an immersive gaming experience. Sadly, it doesn't get very bright, and even though it supports HDR, it can't display a wide color gamut and lacks local dimming.
The Acer Nitro XV340CK is good for office use. It has a large ultrawide screen and a high resolution, great for multitasking. It has decent viewing angles, and the stand has a wide swivel range, making it easy to share your work with coworkers. It handles reflections well, but it doesn't get very bright, so visibility can still be an issue in well-lit environments.
The Acer Nitro XV340CK is a great gaming monitor. It has low input lag, a fast response time, and a high refresh rate to provide a smooth and responsive gaming experience. It has FreeSync support and is also compatible with G-SYNC to help reduce screen tearing. Sadly, its IPS panel's low contrast ratio makes it less ideal for gaming in the dark.
The Acer Nitro XV340CK is good for media consumption. Its large ultrawide screen and high resolution provide an immersive viewing experience. It has decent viewing angles for sharing content, and it handles reflections well. Unfortunately, it has a mediocre contrast ratio that makes it less ideal for dark rooms. Also, even though it supports HDR, it can't display a wide color gamut and doesn't get bright enough to deliver a satisfying HDR experience.
The Acer Nitro XV340CK is good for content creation. Its ultrawide format allows you to work comfortably with multiple windows opened side-by-side, and you can see all the fine details of your work thanks to its high resolution. It has good reflection handling, but visibility can still be an issue in very bright rooms. Unfortunately, it has a low contrast ratio, and its out-of-the-box color accuracy is just okay.
The Acer Nitro XV340CK is okay for gaming in HDR. It delivers a great gaming experience with its low input lag, high refresh rate, and fast response time. However, it can't display a wide color gamut, lacks local dimming, and doesn't get bright enough to make highlights stand out in HDR content.
The Acer Nitro XV340CK has a simple and minimalist design. It has thin borders on three sides with a slightly thicker bottom bezel. The stand is also simple; it has a plain metal bar mounted on a round base.
The stand has a round base that doesn't take up much space. It supports the monitor well, and wobbling is minimal.
The Acer Nitro XV340CK has good ergonomics. Like the Acer Nitro XF252Q, it has a base plate that can rotate freely within the plastic enclosure, allowing it to have a full 360-degree swivel range. It can't rotate to portrait mode due to its ultrawide format.
The back of the monitor is fairly plain. It's VESA-mountable, but unfortunately, there isn't a quick release feature. There's a small hook at the bottom of the stand that serves as cable management.
The borders are thin and aren't distracting, great for multi-monitor setups.
The screen is relatively thin, and the stand doesn't take up much space either.
The Acer XV340CK has decent build quality and very similar to the Acer Nitro XF252Q. The screen is entirely plastic and doesn't feel particularly premium, but there are no obvious gaps in the construction. The stand's trunk is metal, and there's also a metal plate under the base's plastic shell. The plastic used on the base feels cheap, and the adjustment hinges are of lesser quality. It's pretty stable, though, and doesn't wobble much.
The Acer Nitro XV340CK has a mediocre contrast ratio, typical of most IPS panels. As a result, blacks look grayish in the dark.
Note that the contrast ratio can vary between units.
The Acer Nitro XV340CK Pbmiipphzx 34 doesn't have a local dimming feature. The video above is provided for reference only.
The SDR peak brightness is okay. It's incredibly consistent across different content, but it isn't quite enough to overcome glare in a bright environment, so it's better suited for a dark to moderately-lit room.
We measured the SDR peak brightness after calibration, using the 'User' Picture Mode, with Brightness set to max.
Poor HDR peak brightness. The Acer XV340CK can't get bright enough to bring out highlights, so HDR content doesn't look much different from SDR.
We measured the HDR peak brightness using the 'HDR Mode' Picture Mode, with Brightness set to max, and HDR set to 'Auto'.
Note that there's both an 'HDR Mode' Picture Mode, and an 'HDR' setting with an 'Auto' or 'Off' option. The 'HDR Mode' Picture Mode isn't real HDR, as it only adjusts the colors to look like HDR. For proper HDR support, set HDR to 'Auto'.
Although the Acer Nitro XV340CK has an IPS panel, it only has decent horizontal viewing angles. When moving off-center, it loses brightness relatively quickly, and colors appear washed out. That said, unless you need to share work that requires the highest image accuracy, it should be okay for most uses.
Mediocre vertical viewing angles. This causes images to look inaccurate if you sit too close to the screen or have the monitor mounted above eye level.
Our unit of the Acer Nitro XV340CK has excellent gray uniformity. The sides are visibly darker, but thankfully, there's almost no dirty screen effect, and uniformity is much better in dark scenes.
Note that gray uniformity can vary between units.
Black uniformity is mediocre on our unit. There's clouding throughout the screen, as well as some backlight bleed along the top and bottom edges.
Note that black uniformity can vary between units.
Out-of-the-box, the color accuracy is okay. Most colors are only slightly inaccurate, but white balance is visibly off. The color temperature is very close to our 6500K target, leaning just a bit on the cooler side. Gamma doesn't follow the sRGB curve well, making most scenes too bright and dark scenes too dark. There's an 'sRGB' Picture Mode; however, it isn't as accurate as the 'HDR Mode'. The 'HDR Mode' isn't real HDR; it adjusts the colors to make SDR content look like HDR. The sRGB mode results in a higher average color dE of 4.15, a white balance dE of 5.58, a 6275K color temperature, and a 98.1cd/m² luminance.
Note that color accuracy can vary between units.
After calibration, the color accuracy is exceptional. The remaining color inaccuracies shouldn't be visible. White balance is almost perfect, and the color temperature is a little closer to our target. Gamma has improved, but very dark and very bright scenes are over-brightened.
You can download our ICC profile calibration here. This is provided for reference only and should not be used, as the calibration values vary per individual unit, even for the same model, due to manufacturing tolerances.
The Acer XV340CK has an excellent SDR color gamut. It covers the widely-used sRGB color space almost entirely, and it has good coverage of the Adobe RGB color space used in photo editing.
Outstanding SDR color volume. It has difficulty displaying dark and saturated colors due to its low contrast ratio. It has trouble with bright blues, but that's typical for LCDs.
Unfortunately, the Acer Nitro XV340CK can't display a wide color gamut. The DCI P3 coverage is much lower than the Rec. 2020's due to the monitor's low brightness, as it needs to de-saturate colors to reach our target brightness for measuring the color gamut. It doesn't need to perform such de-saturation at a lower brightness target; however, we kept the stimulus at 50% to be consistent with other reviews.
The Acer Nitro XV340CK has a bad HDR color volume, mostly due to its color gamut. It has trouble displaying both very bright and very dark colors.
There are no signs of image retention after displaying a high-contrast image for ten minutes. However, this can vary between units.
Gradient handling is superb. You shouldn't see any banding in regular content.
There are no signs of color bleed on the Acer Nitro XV340CK Pbmiipphzx 34.
The Acer XV340CK has good reflection handling. However, visibility can still be an issue in bright rooms due to the monitor's low brightness.
Text clarity is good. Windows ClearType makes the text look more even and fleshed-out (top photo), especially with diagonal lines. The pixels look blurry due to the monitor's matte anti-reflective coating.
|Overdrive Setting||Response Time Chart||Response Time Tables||Motion Blur Photo|
The Acer Nitro XV340CK has excellent response time at its maximum 144Hz refresh rate, resulting in clear motion in fast-moving scenes. The best overdrive setting is 'Normal', which provides the best performance while keeping overshoot to a minimum. The 'Off' setting is slower, and the 'Extreme' setting causes far too much overshoot.
|Overdrive Setting||Response Time Chart||Response Time Tables||Motion Blur Photo|
The response time at 60Hz is good. The best overdrive setting is 'Off', as the 'Normal' and 'Extreme' settings cause significantly more overshoot and don't improve the response time. This means that you need to change the overdrive setting if your game tends to run closer to 60fps.
The backlight is flicker-free at all brightness levels, great for helping reduce eye strain.
The Acer Nitro XV340CK has an optional Black Frame Insertion feature to help improve motion clarity. However, it causes motion duplication due to the flickering frequency. Also, like most monitors, it isn't usable when VRR (variable refresh rate) is enabled.
The Acer Nitro XV340CK has an outstanding refresh rate, resulting in a smooth and responsive gaming experience. It has native FreeSync support and G-SYNC compatibility to reduce screen tearing, but it seems to only work over a DisplayPort connection at this time. FreeSync causes the screen to flicker and shut off over HDMI and would require a power cycle to get the monitor working again. This is likely a bug that'll be fixed in a firmware update. We'll retest it once the update is available. If you want an ultrawide monitor with a higher refresh rate, check out the Samsung Odyssey G9.
