The Acer Nitro XV340CK Pbmiipphzx 34 inch 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.

Differences Between Sizes And Variants

We tested the Acer Nitro XV340CK Pbmiipphzx, and it's only available in a 34 inch size. There's a smaller 16:9 variant; however, it has a 1080p screen, and we expect it to have different performance.

Model Size Resolution Refresh Rate
Nitro XV340CK Pbmiipphzx 34" 3440 x 1440 144Hz
Nitro XV240Y Pbmiiprx 23.8" 1920 x 1080 144Hz

If someone comes across a different type of panel or if their Acer Nitro XV340CK Pbmiipphzx 34 inch doesn't correspond to our review, let us know, and we'll update the review. Note that some tests, such as gray uniformity, may vary between individual units.

Our unit was manufactured in May 2020; you can see the label here.

Build Quality

The Acer Nitro XV340CK Pbmiipphzx 34 inch has a 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.

Poor HDR peak brightness. The Acer Nitro XV340CK Pbmiipphzx 34 inch 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'.

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/mĀ² luminance.

Unfortunately, the Acer Nitro XV340CK Pbmiipphzx 34 inch 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. If you want an ultrawide monitor that can display a wide color gamut, check out the ASUS TUF Gaming VG34VQL1B.

Update 01/13/2022: We retested the VRR using an HDMI connection with our RX 6800 graphics card. We confirmed that FreeSync works over its entire refresh rate range with HDMI, but only with newer graphics cards and not older ones.

The Acer Nitro XV340CK Pbmiipphzx 34 inch 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, and it works with DisplayPort and HDMI with newer Radeon graphics cards. On older cards, FreeSync causes the screen to flicker and shut off over HDMI and would require a power cycle to get the monitor working again. If you want an ultrawide monitor with a higher refresh rate, check out the Samsung Odyssey G9.

The Acer Nitro XV340CK Pbmiipphzx 34 inch has an exceptionally low input lag, and it remains low even with VRR enabled. Unfortunately, we lack the necessary tools to measure the input lag with 10-bit HDR over a DisplayPort connection. Over HDMI, we can only get an 8-bit signal at 100Hz with an input lag of 5.2ms, or a 12-bit signal at 30Hz with an input lag of 50.1ms.

The Acer Nitro XV340CK Pbmiipphzx 34 inch has an ultrawide screen and 1440p resolution that are excellent for gaming and productivity. There's enough screen space to have multiple windows opened side-by-side and gives you a wider field of view in your games. However, not all games support ultrawide formats, so you might see some black bars on the sides, or the picture might be stretched out to fill the screen.
