The Acer Predator X25 bmiiprzx is an excellent gaming monitor. Unlike the larger 4k Acer Predator X27 bmiphzx, it's limited to a 1080p resolution but has an exceptionally high 360Hz refresh rate, making it well-suited for esports competitors or serious gamers who prioritize motion clarity over picture quality. It has a remarkably fast response time at both 60Hz and 360Hz, low input lag, and G-SYNC variable refresh rate (VRR). While it has a low contrast ratio, as expected of an IPS panel, the black uniformity on our unit isn't bad for an IPS monitor, although uniformity can vary. It gets quite bright in SDR, so glare shouldn't be an issue, although its HDR brightness is a bit limited, resulting in an underwhelming HDR experience, especially compared with the X27. On the upside, it has great viewing angles and good ergonomics that allow you to set the screen exactly as you like.
The Acer X25 is great for mixed usage. It's bright enough for most environments and has good reflection handling to overcome glare. It excels in gaming features, with an exceptionally high refresh rate, fast response times, and low input lag. It also has an excellent SDR color gamut, which is great for multimedia and media creation. However, the 25 inch screen and 1080p resolution may not be large or sharp enough for some when it comes to watching movies or multitasking. Also, it's not quite bright enough to deliver a truly satisfying HDR experience.
The Acer Predator X25 is very good for office use. It's bright enough to overcome glare in most lighting conditions, and it has good ergonomics, so you can adjust it how you like, including rotating it into portrait mode. Its wide viewing angles are also good for sharing content. However, its 25 inch size and 1080p resolution result in a low pixel density, producing an image that may not be sharp enough for some.
The Acer X25 is excellent for gaming. It has a high 360Hz refresh rate and fast response times for exceptionally clear motion. It also has low input lag and supports G-SYNC VRR to reduce screen tearing. Unfortunately, FreeSync may not work, and some gamers may prefer a monitor with a higher resolution or larger screen.
The Acer X25 is good for multimedia. It has good viewing angles, so the image stays accurate from the side, great for watching movies with friends. It also has good ergonomics, so you can set it to your ideal viewing position. Unfortunately, its smaller size and 1080p resolution may be too limited for some, and its low contrast ratio makes blacks look more like gray in the dark.
The Acer X25 is very good for media creation. It has an excellent SDR color gamut, though its coverage of the Adobe RGB color space may be too limited for professional photo editing. Still, it has wide viewing angles that are great for sharing content with another person, and it has good ergonomics. It also gets bright enough to overcome glare in most rooms. Unfortunately, it's limited to a 1080p resolution and has a low pixel density.
The Acer Predator X25 is decent for HDR gaming. Its gaming performance is amazing, with a 360Hz refresh rate and fast response time for smooth motion. It also has low input lag and VRR support. However, it can't display a wide HDR color gamut, and it doesn't get quite bright enough to make highlights pop, resulting in an underwhelming HDR experience.
The Acer Predator X25 looks pretty sleek and elegant, with gamer-oriented flourishes. It has a thicker bottom bezel with the 'Predator' logo that sticks out, while the others are very thin and designed to look barely there when the monitor is off.
The stand has a different design than the Acer Predator X27 bmiphzx. It's slightly raised with curved, metal feet. They're quite thin, but overall, the stand supports the monitor well.
The Acer Predator X25 has good ergonomics, so you can adjust it as you like. It can rotate into portrait mode in either direction, has decent height adjustment, and a wide tilt range, although the swivel range is quite limited.
The back is plastic with a patterned rectangular portion and RGB lighting. There's a cutout in the stand for cable management.
The monitor itself isn't too thick. It takes up more space with the stand, but you should still have plenty of room on your desk.
The Acer X25 is made mostly of plastic and feels well-built, although it doesn't feel as premium as the Acer Predator X27 bmiphzx. There's not much flex on the back panel, but the bottom bezel on the front flexes easily. The monitor doesn't wobble or move, though, and it feels quite sturdy.
It has a mediocre native contrast ratio, so blacks look more like gray when viewed in the dark. It's slightly higher than the advertised 1000:1 contrast ratio. That said, contrast can vary a bit between units.
The Acer X25 doesn't have a local dimming feature. There's a Variable Backlight setting, but it's a dynamic contrast feature rather than local dimming. The video above is provided for reference only.
The SDR peak brightness is great. It can hit the advertised 400 nits, although most real scenes will likely fall slightly below that. It's very consistent across different scenes, and it's bright enough to overcome glare in most lighting conditions.
We measured brightness after calibration, in the 'User' Picture Mode, with the Max Brightness setting enabled, and Peak White set to '450'.
HDR peak brightness is okay. It meets the brightness requirement of its advertised DisplayHDR 400 certification, but it may not be bright enough to deliver a satisfying HDR movie experience.
We measured HDR brightness before calibration on the 'User' Picture Mode, with Max Brightness enabled.
The Acer X25 has great horizontal viewing angles. For the most part, the image should stay accurate from the side.
The Acer X25 has decent vertical viewing angles, but you may still notice some image inaccuracy if you mount it above eye level.
The Acer Predator X25 has excellent gray uniformity, although this can vary between units. While the top corners and edges are noticeably darker, the screen is very uniform overall. In near-dark scenes, it's even better.
The Acer X25 has mediocre black uniformity. There's some blooming around bright objects and a bit of clouding throughout, but it's not bad for an IPS monitor. That said, black uniformity can vary between units.
The Acer X25 has impressive out-of-the-box color accuracy, but this can vary between units. Most colors and the white balance are not too far off, and the gamma follows the curve very well, although some dark scenes may appear brighter than they should. The color temperature is on the colder side, giving the image a blue tint. There's an 'sRGB' Picture Mode, but we used the 'Racing' mode since it's more accurate.
After calibration, accuracy is fantastic. Any remaining inaccuracies shouldn't be noticeable without a colorimeter, and the color temperature is nearly perfect. Gamma follows the target even better, though dark scenes may still be over-brightened a little bit.
You can download our ICC profile calibration here. This is provided for reference only and shouldn't be used, as the calibration values vary per individual unit, even for the same model, due to manufacturing tolerances.
The Acer X25 has an excellent SDR color gamut. Its coverage of the sRGB color space is nearly perfect, but it's only decent when it comes to the wider Adobe RGB used in photo editing.
SDR color volume is excellent. It can't produce very dark, saturated colors because of its low contrast ratio, but it can display a wide range of colors at higher luminance levels.
HDR color gamut is okay, but it can't display a wide color gamut for HDR content. While it has good coverage of the DCI P3 color space, its coverage of the wider Rec. 2020 is sub-par.
Due to the way we measure the DCI P3 coverage, our measurement is likely lower than most other reviewers. We measure it by sending a Rec. 2020 signal, but unlike most reviewers, we limit the colors to the DCI P3 primaries. This results in a lower but arguably more accurate measurement.
HDR color volume is not bad, but it's limited by its low contrast ratio and lack of a wide color gamut.
There are no signs of image retention after displaying a high-contrast static image, but this may vary between units.
Gradients look fantastic. There's hardly any noticeable banding.
There's almost no color bleed on the Acer Predator X25. The little bit of vertical color bleed shouldn't be noticeable in real content.
Very good reflection handling. It diffuses direct reflections very well, but ambient lighting may still be distracting in well-lit rooms.
Text clarity is decent. With ClearType enabled (top picture), diagonal and curved lines appear a bit clearer, as seen in the N or the G, but straight lines are less bold, as seen in the T and I.

The Acer X25 has a remarkable response time at its max 360Hz refresh rate, resulting in clear motion with minimal blur trail. The best overdrive setting is 'Off', since the other settings produce too much overshoot.
The Acer X25 is flicker-free, which can help reduce eye strain.
The Acer X25 has an optional Black Frame Insertion feature to help reduce motion blur further, called NVIDIA ULMB. You can adjust the pulse width for BFI in the on-screen display from a range of 10 to 100. Changing the pulse width affects the clarity and brightness of the screen with BFI. The picture above is with the pulse width set to 100. You can see how it looks at 10 here. The flicker frequency range is somewhat narrow, though, and BFI can't be enabled with VRR. Note that our BFI score is based on the flicker range and not the actual performance.
