The Acer Nitro XV275K P3biipruzx is a 27-inch, 4k gaming monitor. It comes with premium features like Mini LED backlighting and HDMI 2.1 bandwidth, competing with models with the same features, like the Cooler Master Tempest GP27U, and it comes at a mid-range price tag. It has a max refresh rate of 160Hz and includes variable refresh rate (VRR) support to reduce screen tearing. Besides its gaming perks, it even features a USB-C port that supports DisplayPort Alt Mode, and there are two USB-A ports to connect to other devices.
The Acer Nitro XV275K P3 is good for PC gaming. It has a 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.
The Acer Nitro XV275K is excellent for console gaming. It has HDMI 2.1 bandwidth to take full advantage of the PS5 and Xbox Series X|S, and its 4k resolution delivers detailed images. Gaming feels smooth thanks to its fast response time, and it has low input lag at 120Hz, but its input lag increases at 60Hz, which is disappointing for playing reaction-based games. It also has decent picture quality in HDR and SDR, as its decent local dimming feature helps it display deep blacks, but there's some blooming around bright objects.
The Acer Nitro XV275K is excellent for office use. It has a high 4k resolution that results in high pixel density and very sharp text clarity, and its 27-inch screen is big enough to open two windows side-by-side. You won't have any issues using it in a bright room, as it gets very bright and has good reflection handling. It's also ideal for sharing your screen with others thanks to its outstanding ergonomics and wide viewing angles. On top of that, it has some productivity features, like a USB-C port with 90W of power delivery, enough to charge your laptop while you're using it.
The Acer XV275K P3 is great for media creation. It has an extremely accurate sRGB mode, so you don't need to calibrate it for the most accurate colors. It also delivers sharp images and text thanks to its 4k resolution and high pixel density. You can easily share the screen with others, like a coworker or client, as its outstanding ergonomics and wide viewing angles keep the image consistent from the sides. It also has good reflection handling and gets bright enough to fight glare in a well-lit room.
The Acer Nitro XV275K has excellent brightness. It gets bright both in SDR and HDR, so it can either fight glare in a well-lit environment or make small highlights stand out in HDR for a vivid experience.
The Acer Nitro XV275K has a good overall response time. It performs best at its max refresh rate as it has minimal CAD, but the CAD increases at lower refresh rates. This also means that its motion handling in VRR is good, but motion looks worse if your PC can't maintain a high frame rate.
The Acer Nitro XV275K is decent for HDR. It has a decent Mini LED local dimming feature that helps it display deep blacks and improve the contrast in dark scenes. It also displays a wide range of colors in HDR, but with some tone mapping issues, not all colors are accurate. On the plus side, it gets very bright in HDR, enough to make highlights stand out.
The Acer Nitro XV275K has decent picture quality in SDR. It displays a wide range of colors, but the main downside is its low native contrast ratio, so blacks look gray in dark scenes. It also has some black uniformity issues without local dimming, leading to clouding.
The Acer Nitro XV275K has fantastic accuracy. It has an extremely accurate sRGB mode, and although calibrating it can improve accuracy, you won't need to for an accurate image. The image also remains consistent across the screen thanks to its good gray uniformity, but the edges are darker than the rest of the screen.
We tested the 27-inch Acer Nitro XV275K, which is the only size available for this monitor, so the results are only valid for this review. It's a higher-end monitor than the Acer Nitro XV275U P3biipx, which also uses Mini LED backlighting but has a lower 1440p resolution and fewer features.

The Acer Nitro XV275K is a good 4k gaming monitor that combines its gaming performance with great picture quality thanks to its Mini LED backlighting and decent local dimming feature. It delivers good picture quality compared to other LED-backlight monitors, especially for its price range, and it's a good alternative to the Cooler Master Tempest GP27U and the INNOCN 27M2V. There are a few issues with it, though, like its increased input lag at 60Hz, so it isn't ideal for all types of gamers. If that's important for you, you can also consider the Samsung Odyssey Neo G7 S32BG75, but that monitor has VRR flicker during changing frame rates.

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 console 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.
The Acer Nitro XV275K P3biipruzx is a higher-end monitor than the Acer Nitro XV275U P3biipx, so it has more features and is the better choice for most people. The XV275K's higher resolution results in a more detailed and sharper image, and it has HDMI 2.1 bandwidth to take full advantage of gaming consoles and modern graphics cards. The XV275K also has extra productivity perks that the XV275U doesn't have, like a USB hub that includes a USB-C port for you to easily connect a laptop. However, the XV275U is the better choice if you want to watch content in dark rooms and you aren't going to use the local dimming feature, as it has a higher native contrast ratio.
The Acer Nitro XV275K P3biipruzx and the Cooler Master Tempest GP27U are similar 27-inch, 4k monitors with Mini LED backlighting. However, there are a few differences between them, as the Acer has much better accuracy before calibration and slightly better reflection handling. The Cooler Master has better motion handling, particularly at lower refresh rates, and lower input lag for a more responsive feel. The Cooler Master even has a KVM switch, ideal for multitasking, which the Acer doesn't have.
The Acer Nitro XV275K P3biipruzx and the INNOCN 27M2V are similar 27-inch, 4k monitors with Mini LED backlighting. There are a few differences between them as the INNOCN 27M2V has a slight advantage in picture quality because it has a superior local dimming feature with more dimming zones and gets brighter, too. They each have similar motion handling, but the INNOCN has a slight advantage because it maintains its sharp motion handling better at lower refresh rates. That said, the Acer delivers more accurate colors, making it the better choice for office use and content creation.
The Acer Nitro XV272U KVbmiiprzx and the Acer Nitro XV275K P3biipruzx are different types of monitors. The XV275K has a higher 4k resolution and features Mini LED backlighting, which the XV272U doesn't have. This makes the XV275K the better choice for use in dark rooms, and it gets much brighter, too. The XV275K also features HDMI 2.1 bandwidth, which makes it the better choice for console gaming. The XV272U has lower input lag for a more responsive feel, which is ideal if you need something for playing reaction-based games.
The Acer Nitro XV275K P3biipruzx and the MSI MAG 274UPF are 27-inch 4k gaming monitors. Both are well-suited to gaming and productivity work. The MSI is a great option if you don't need enhanced gaming performance. However, the Acer is a better choice if you want highlights that pop, vivid HDR colors, better motion handling, and deep blacks next to bright highlights.
The Acer Nitro XV275K P3biipruzx and the Sony INZONE M9 are both 4k gaming monitors, with a few differences. The Acer has Mini LED backlighting with a better local dimming feature than the Sony, meaning it's better for HDR or any other use in dark rooms. The Acer also has much better ergonomics, making it easier to place in an ideal position. Lastly, the Acer has a slightly higher refresh rate and better motion handling at high refresh rates, but the Sony is better for gaming at low refresh rates because it has lower input lag.
The Acer Predator X32 Fpbmiiiiphuzx and the Acer Nitro XV275K P3biipruzx are both 4k monitors with Mini LED backlighting, but they have some differences. The X32 is bigger and has a few extra features, like a KVM switch and built-in speakers. The XV275K has an advantage for motion handling, but the X32 has lower input lag at 60Hz, which is great for gaming. They perform similarly otherwise, but the XV275K has better accuracy before calibration.
The LG 27GS95QE-B and the Acer Nitro XV275K P3biipruzx are both 27-inch gaming monitors. The Acer is more versatile and works extremely well as both a gaming and productivity monitor. It has a higher resolution with greater text clarity, a USB-C input with 90W of power delivery, and it has no risk of burn-in during productivity use, unlike the LG. The Acer is also much brighter and performs better in very bright environments. However, the LG is a better choice if you're spending most of your time gaming, as fast-moving objects are crisper and sharper, and it has a higher refresh rate for a smoother gaming experience. Additionally, because it's an OLED, it has near-perfect contrast, so it displays inky blacks next to bright highlights in dark rooms.
The Acer Nitro XV252K has a rather simple aesthetic with an all-black plastic body and a plain back that has a strip of RGB backlighting. It also features a tripod stand with wide-set feet.
The build quality is great. There aren't any obvious issues, and it's mainly made of plastic that feels well-built with minimal bending. Only the base of the stand is metal, and adjusting the screen on the stand feels stable. There isn't any noticeable fan noise, but you can hear some very minor noise if you put your ear right up to the monitor, which is normal.
The Acer XV275K has outstanding ergonomics, as you can easily adjust it. It's best to use this monitor with the included stand because the VESA mounting size is 75x75, so it's too small to use a 100x100 mounting arm, which is disappointing. Lastly, the stand features a clip for cable management.
The monitor has five buttons to control the on-screen display, but they aren't user-friendly. They feel stiff, and they even leave an imprint on your fingers. The OSD is also difficult to use, as settings with numbered adjustments take time to change, and some settings, like its RGB lighting, even reset to their default when changing other settings. While this isn't an issue if you don't change settings much, it's a downside if you like to change settings often.
The contrast ratio of the Acer XV275K is acceptable. Its full-array local dimming feature helps it display deep blacks with most content, but it doesn't show this with the checkerboard test pattern. Interestingly, setting Adaptive Dimming to 'Fast' results in a lower contrast with the checkerboard pattern than setting it to 'Low', which has a contrast of 2,625:1, but 'Fast' still offers the best overall performance.
The picture above has a warm color temperature, but this is due to an interaction between the camera and the display, similar to the Acer Predator X32 Fpbmiiiiphuzx. This isn't visible in person, though.
The full-array Mini LED local dimming feature has 576 dimming zones and performs decently. Setting Adaptive Dimming to 'Fast' results in the best performance out of the three settings, as it helps it display deep blacks. There isn't too much blooming either, but it doesn't completely eliminate it as there's a bit around bright objects, like subtitles, and the blooming looks worse from the sides than from in front. If you want something with a bit less blooming, though, then consider the AOC Q27G3XMN.
As for the Acer, it keeps details well in dark scenes as there's minimal black crush because the 'Fast' setting spreads light across zones at the expense of the contrast. Besides that, the algorithm keeps up with fast-moving objects well, but there's visible flicker when viewing from the sides, and it's still noticeable when each zone turns on and off.
The Acer Nitro XV275K has excellent SDR peak brightness. It easily gets bright enough to fight glare and maintains its brightness well across different content. These results are from after calibration in the 'User' Picture Mode with the Brightness at its max, Max Brightness on, and Adaptive Dimming on 'Fast'. The screen actually gets brighter in the Real Scene test with Adaptive Dimming off as it goes up to 605 cd/m², but the overall picture quality is worse with it off due to its lower contrast.
Unfortunately, the minimum brightness is high if you're sensitive to bright lights and want to use it in a dark room. This result is with Max Brightness on and Adaptive Dimming on 'Low' as it gets brighter with any other combination of settings, even with Max Brightness and Adaptive Dimming off.
The HDR brightness is fantastic. It easily gets bright enough to make highlights stand out and pop, but small highlights are muted. The PQ EOTF tracking is decent, but dark scenes are slightly too dark. That said, because there's a sharp roll-off at the peak brightness, it lets highlights get the brightest they can.
These results are with HDR on, Max Brightness on, Brightness at its max, and Adaptive Dimming on 'Fast'. Like in SDR, the Real Scene test gets brighter with local dimming off, but the picture quality is best with it on 'Fast', and the EOTF is the same between any of the local dimming settings.
The Acer Nitro XV275K P3 has a decent horizontal viewing angle. While the image washes out from wide angles, it's still good enough to share the monitor with someone sitting next to you.
The vertical viewing angle is good. The image remains consistent if you're standing up and looking down at the monitor.
The Acer XV275K P3 has good gray uniformity. While the edges of the screen are slightly darker, there's minimal dirty screen effect in the center, which is great.
The picture above has a warm color temperature, but this is due to an interaction between the camera and the display, similar to the Acer Predator X32 Fpbmiiiiphuzx. This isn't visible in person, though.
The black uniformity is decent, and it performs best with local dimming enabled. It helps it display deep blacks, and there isn't too much blooming, but it doesn't completely eliminate all blooming, either. Turning off local dimming results in a worse contrast ratio, and there's more backlight bleed.
The Acer Nitro XV275K has incredible accuracy before calibration in the sRGB mode. Setting Color Space to 'sRGB' locks colors well to the sRGB color space, and colors and the white balance have minimal inaccuracies. The color temperature is also close to the 6500K target, and gamma follows the sRGB curve well, but some dark scenes are too dark. Unfortunately, using the 'sRGB' Color Space setting locks other settings, including Contrast and Black Boost. So, if you want to use those settings, you need to change Color Space to something else, which results in oversaturated colors.
The accuracy after calibration is remarkable. There aren't any obvious inaccuracies, and the main advantage of calibrating it is that you get access to other settings, and the image also gets bright.
The SDR color gamut is fantastic. It has perfect coverage of the commonly-used sRGB color space and displays a wide range of colors in the Adobe RGB space used in photo editing, but it does this by oversaturating colors.
The Acer XV275K has a fantastic HDR color gamut. It displays a wide range of colors in both the DCI-P3 and Rec. 2020 color spaces, and there are minimal tone mapping issues.
The text clarity is fantastic, thanks to its high pixel density. Enabling Windows ClearType (top photo) helps improve the text clarity with bolder lines. These photos are in Windows 10, and you can also see it in Windows 11 with ClearType on and with ClearType off.
The Acer XV275K has good reflection handling. While it struggles with strong light sources directly on it, it easily gets bright enough to fight intense glare.
The pictures above have a warm color temperature, but this is due to an interaction between the camera and the display, similar to the Acer Predator X32 Fpbmiiiiphuzx. This isn't visible in person, though.
The gradient handling is outstanding, and you won't notice any issues with banding in scenes with shades of similar colors, like a sunset.
The picture above has a warm color temperature, but this is due to an interaction between the camera and the display, similar to the Acer Predator X32 Fpbmiiiiphuzx. This isn't visible in person, though.
The Acer Nitro XV275K has a high 160Hz refresh rate. There's a Max Refresh Rate setting that's set to '144Hz' out of the box, but you just need to change it to '160Hz' to reach its max refresh rate. However, the refresh rate is limited to 144Hz over HDMI, even if the Max Refresh Rate setting is at '160Hz', and the only way to get a true 160Hz refresh rate over HDMI is with a custom resolution.
NVIDIA | VRR Min | VRR Max |
DisplayPort | <20Hz | 160Hz |
HDMI | <20Hz | 144Hz |
AMD | VRRMin | VRRMax |
DisplayPort | <20Hz | 160Hz |
HDMI | <20Hz | 144Hz |
On top of supporting FreeSync and G-SYNC compatibility, it also supports HDMI Forum VRR. While VRR works well and reduces screen tearing, there's one bug when it's part of a multi-monitor setup. With VRR enabled at a high refresh rate on the Acer monitor and a secondary monitor that's also using VRR at a low refresh rate, there are some handshaking issues, as you can see here and here. This can be problematic if you have a secondary monitor with extra info while you're gaming on this monitor; otherwise, if you just have the monitor on its own, it isn't an issue.

The Acer XV275K has good motion handling across its refresh rate range with VRR enabled. Although enabling VRR locks you out of changing any Over Drive settings, it just uses the last selected one, and you can only change it by disabling VRR. Turning the setting off produces the best results across the entire refresh rate range, and while 'Normal' performs similarly, it's worse at lower refresh rates. 'Extreme' has such a high CAD at low refresh rates that it extends past the limit of the chart, as you can see here.
The refresh rate compliance is good. Its response time isn't fast enough to take advantage of its max refresh rate, but it's still good enough for most games. The 'Off' and 'Normal' Over Drive settings perform similarly, and although 'Normal' has an advantage for most refresh rates, motion looks better with 'Off' over the entire refresh rate range.
Overdrive Mode | CAD Heatmap | RT Chart | Pursuit Photo |
Off | Heatmap | Chart | Photo |
Normal | Heatmap | Chart | Photo |
Extreme | Heatmap | Chart | Photo |
The CAD at the max refresh rate is great. The 'Normal' Over Drive setting has a faster response time than 'Off,' leading to sharper motion and a lot less overshoot and inverse ghosting than 'Extreme.'
Overdrive Mode | CAD Heatmap | RT Chart | Pursuit Photo |
Off | Heatmap | Chart | Photo |
Normal | Heatmap | Chart | Photo |
Extreme | Heatmap | Chart | Photo |
The response time at 120Hz is great. Like at its max refresh rate, its recommended Over Drive setting is 'Normal,' but it has a bit more overshoot that causes inverse ghosting than 'Off,' so it's better to turn the setting off if that bothers you.
Overdrive Mode | CAD Heatmap | RT Chart | Pursuit Photo |
Off | Heatmap | Chart | Photo |
Normal | Heatmap | Chart | Photo |
Extreme | Heatmap | Chart | Photo |
The CAD at 60Hz is good. Unlike at higher refresh rates, the 'Off' Over Drive setting produces the best motion as it has less inverse ghosting than 'Normal' and 'Extreme'. This means you may need to change the setting if you change games and start to play at a lower frame rate.
The Acer Nitro XV275K has no optional backlight strobing feature to reduce persistence blur.
The Acer Nitro XV275K has low input lag for a responsive feel at high refresh rates. However, the input lag increases significantly at 60Hz, which is problematic for playing reaction-based games at that refresh rate, like from consoles.
The Acer XV275K P3 works well with the Xbox Series X|S, as it supports anything up to 4k @ 120Hz. Like other monitors, you need to enable the HDMI override setting in the console for 1440p @ 60Hz to work, which disables VRR. The Xbox doesn't support HDR with 1080p or 1440p signals, so this isn't an issue with the monitor.
With the USB-C port, you can connect your laptop and charge it simultaneously, as the 90W of power delivery is high enough to charge most laptops.
The Acer Nitro XV275K works well with macOS. Over USB-C, the default resolution is 1080p, so you need to change it to 4k, and the max refresh rate is 144Hz. VRR and HDR work simultaneously, and if you're using a MacBook and close the lid, windows return to their original position when opening it again. The supported signals over HDMI depend on which computer you're using, as it's limited to 4k at 30Hz or 60Hz with an HDMI 2.0 MacBook, but an HDMI 2.1 MacBook supports up to 144Hz with VRR.
The Acer Nitro XV275K has a few extra features, including:
While there's a USB Port Select setting to change which USB upstream port you want to use, either USB-B or USB-C, this isn't the same as a KVM switch, and it doesn't automatically change when you switch inputs.
As explained in the controls section, the OSD isn't user-friendly, and it takes time to switch settings with slider toggles, like Brightness and Contrast, especially if you need to go from the minimum to the maximum.
