The Acer Nitro XV275K P3biipruzx is a 27-inch, 4k gaming monitor. It has an IPS panel with Mini LED backlighting and has gaming features like FreeSync Premium Pro, HDMI 2.1 bandwidth, and a 160Hz refresh rate. It has other productivity features like a USB-C port that supports DisplayPort Alt Mode and two USB-A ports to connect other devices.

Our Verdict
The Acer Nitro XV275K P3 is good for PC gaming. It has a max 160Hz refresh rate and supports all common VRR formats to reduce screen tearing. It has good motion handling with VRR, but there's more blur at lower refresh rates, which isn't ideal if your PC can't maintain high frame rates. While it has low input lag at high refresh rates, its input lag increases at low refresh rates, which is disappointing for playing reaction-based games at low refresh rates too. On the plus side, it has good picture quality with deep blacks and bright highlights, and it also displays a wide range of colors.
- 160Hz refresh rate and VRR support.
- Decent Mini LED local dimming feature.
Minimal blur at high refresh rates.
Input lag increases a lot at 60Hz.
- More overshoot at low refresh rates.

Differences Between Sizes And Variants
We tested the 27-inch Acer Nitro XV275K, model code P3biipruzx, which is the only size available for this monitor. The full model code may vary between regions or retailers, and some retailers sell it with a square-based stand, but it performs the same. Some users have also reported that there are units of this model that support a 4k @ 160Hz signal over HDMI, while we can only get up to 144Hz on our unit.
Part of the Nitro XV5 lineup, it sits alongside other 27-inch monitors that share a similar name but are different, which you can see below. The results are only valid for the XV275K P3. It's since been replaced by the Acer Nitro XV275K P5biipruzx, which has a dual mode that increases its refresh rate to 320Hz with a lower 1080p resolution.

Popular Monitor Comparisons
The Acer Nitro XV275K P3biipruzx is a 27-inch, 4k monitor that offers both great gaming performance and good picture quality. Its HDMI 2.1 bandwidth lets you take full advantage of modern graphics cards and gaming consoles, and motion looks sharp for the most part. It also displays deep blacks with bright highlights thanks to its Mini LED backlighting, so it's great for HDR. Competing with the Cooler Master Tempest GP27U and the INNOCN 27M2V, you can usually find it for less than the competition when it's on sale, making it a great choice if you want a mid-range gaming monitor and don't want to spend more on an OLED. That said, it isn't perfect, as its increased input lag at 60Hz can be problematic for some gamers.

The Acer Nitro XV275K P3biipruzx and the AOC Q27G40XMN are both gaming monitors with Mini LED backlighting. There are a few differences between them, though, as the Acer is versatile for more uses. It has a higher 4k resolution, resulting in sharper text and more detailed images, ideal for work or content creation. On top of that, the Acer's better ergonomics and wider viewing angles make it a superior choice for sharing your screen with others. The Acer also supports HDMI 2.1 bandwidth to take advantage of gaming consoles, which the AOC doesn't support. The AOC does have a few advantages, though, as it has a higher native contrast ratio and better local dimming feature, making it the better choice for watching content in dark rooms.
The Acer Nitro XV275K P5biipruzx is a newer version of the Acer Nitro XV275K P3biipruzx, with many of the same specs, but a few differences. The P5 has more dimming zones, with 1,152 zones compared to 576 on the P3. However, this doesn't come with an upgrade in performance, as the P5 has more haloing around bright objects, and the local dimming feature only turns on in HDR, whereas you can use it on the P3 in SDR, too. The P3 is a bit more polished when it comes to picture quality, as it's more accurate before calibration and has better reflection handling. However, the P5 is an improvement when it comes to gaming. It has a dual mode that boosts its refresh rate to 320Hz with a lower 1080p resolution for a smoother feel. The P5 also has lower input lag at low refresh rates, which helps if you're gaming with a console.
The Acer Nitro XV275K P3biipruzx and the Dell U2725QE are 27-inch 4k monitors. The Acer is the better option if you plan to view or edit HDR content or play games, as it has far better HDR performance and motion handling, while still being excellent for office work. It also gets much brighter. If you plan to only use the monitor for office work, you may prefer the Dell, as it has better connectivity and a KVM switch.
The Acer Nitro XV275K P3biipruzx and the AOC Q27G3XMN are 27-inch gaming monitors meant for different types of gamers. The AOC has an advantage for gamers because it has much better motion handling across its VRR range, but it has more black smearing than the Acer. That said, the AOC also has lower input lag and a better local dimming feature for improved picture quality in dark scenes. On the other hand, the Acer is better for console gaming, as it has a higher 4k resolution and HDMI 2.1 bandwidth to take full advantage of the PS5 and Xbox Series X|S. The Acer also has less VRR flicker with changing frame rates, which is good if your PC can't maintain consistent frame rates.
We buy and test more than 30 monitors each year, all of which we purchase ourselves, without cherry-picked units or samples. We put a lot into each unbiased, straight-to-the-point review, and there's a whole process from purchasing to publishing, involving multiple teams and people. We do more than just use the monitor for a week; we use specialized, custom tools to measure various aspects and deliver objective, data-driven results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance compared to the competition, and whether it's easy to find.
