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.

Build Quality

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 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.

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.

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 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.

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 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.
