The HP X 25f is a decent 1080p monitor with great gaming performance. The 240Hz refresh rate delivers outstanding clear motion, with an incredibly fast response time. It's very responsive for gaming thanks to the outstanding low input lag, the lowest we've measured so far. This monitor has a great design and it has some great additional features, including an RGB ambient lighting feature. Unfortunately, like other TN monitors we've tested, the image degrades significantly when viewed at an angle, and overall, it delivers mediocre picture quality.
The HP OMEN X 25f has a very good design, nearly identical to the HP OMEN 27. It has thin bezels on three sides, and looks great in a multi-monitor setup or VESA mounted. The stand supports the monitor well and has a relatively small footprint, but has limited ergonomics as it can't swivel and can't be rotated to a portrait orientation. This monitor has excellent build quality; despite being almost entirely made of plastic, it has a premium finish and there are no obvious weak spots.
The border around the monitor is very thin on 3 sides, and blends in when using the monitor. There is an RGB ambient lighting feature along the bottom bezel.
When attached to its stand, this monitor is a bit thicker than most, and it's just as thick as the OMEN 27, despite the smaller screen.
Like most TN monitors we've tested, the HP OMEN X 25f delivers mediocre picture quality. It has a passable contrast ratio, but blacks look gray in a dark room. It has great peak brightness, though, and great reflection handling, so there shouldn't be any issues gaming in a bright room. This monitor also has excellent gradient handling, with very little banding visible in most content. Unfortunately, like all TN monitors we've tested, the image degrades significantly when viewed at an angle.
Great SDR peak brightness; this monitor can get more than bright enough for almost any room. There is no significant variation in brightness with different content.
This monitor does not support HDR.
Disappointing horizontal viewing angle, but this is to be expected with TN panels, and these results are nearly identical to the BenQ Zowie XL2540. When sitting directly in front of the screen, there shouldn't be any issues, but moving even slightly off-center results in a washed out image and a rapid loss of color accuracy.
When looking at the monitor from above, the image gradually loses color accuracy and appears washed out. From below, however, it's much worse, and at wide angles there's a noticeable grayscale inversion, and a negative image appears. When sitting directly in front of the screen, this isn't a significant issue for most people, but if you're too close the top and bottom of the screen can appear non-uniform.
Good gray uniformity, with very little dirty screen effect (DSE). The top of the screen appears noticeably darker than the rest; this is due to the vertical viewing angle. In near-dark scenes, the uniformity is a lot better, but some clouding is still noticeable.
The HP OMEN X 25f has passable black uniformity, very similar to the Acer XF251Q. There is some clouding across the entire screen, but there is no backlight bleed.
Out of the box, the HP OMEN X 25f has decent accuracy. Gamma is almost flat and is close to 2.1, and white balance is noticeably inaccurate, especially in brighter shades of gray. There are noticeable inaccuracies in some colors, and the color temperature is a bit warm.
After calibrating, this monitor has excellent accuracy. There are no noticeable grayscale errors, and most color errors are corrected. Gamma follows the sRGB target curve almost perfectly, and the white balance is very close to the target of 6500K.

sRGB Picture Mode: Native (calibrated)Adobe RGB Picture Mode: Native
Great SDR color gamut, similar to the BenQ Zowie XL2540. It can't quite display the entire sRGB color space, but most people won't notice it. It has only decent coverage of the wider Adobe RGB color space, which isn't great for professional photo editing.
There are no signs of temporary image retention, even immediately after displaying our high contrast, static test image for 10 minutes.
The HP OMEN X 25f has outstanding motion handling. It has an extremely fast 240Hz refresh rate and it delivers one of the fastest response times we've ever measured. It supports FreeSync, but is also officially supported by NVIDIA's new G-SYNC Compatible feature, so FreeSync is automatically enabled when connected to a recent NVIDIA graphics card. The backlight is completely flicker-free, which is great, but there is no optional black frame insertion feature.
The OMEN X 25f has an outstanding response time, slightly faster than the OMEN 27, and even faster than the BenQ Zowie XL2540. The response time can be customized, and there are four different levels. We recommend level 3, as it delivers the best response time with the least amount of overshoot. Level 4 has significantly higher overshoot, and there is almost no improvement to the response time, so we don't recommend it.
The backlight is completely flicker-free, which is great. There is no black frame insertion feature, but this isn't really needed with 240Hz content, as motion is already incredibly clear.
The HP OMEN X 25f has a native 240Hz panel, and it supports FreeSync variable refresh rate technology. It also supports FreeSync when connected via DisplayPort to a recent NVIDIA graphics card, and it's certified compatible by NVIDIA, so it works automatically.
The HP OMEN X 25f has outstanding low input lag, delivering an extremely responsive gaming experience. The 24.5", 1080p screen might bother some people, though, as it isn't as sharp as the latest 1440p or 4k gaming monitors.
This monitor has outstanding low input lag, the lowest we've measured so far. The 60Hz input lag is higher than most monitors, which is a bit disappointing for console gamers.
The HP OMEN X 25f has a few additional features, including an RGB ambient lighting system, but it doesn't support HDR10 and has no built-in speakers. There are a few virtual overlays that can be added to any game, including a frame rate counter and virtual crosshairs.
The OMEN X 25f doesn't support HDR10, and has no built-in speakers, but there are a few additional features. There is an RGB Ambient Lighting feature, which can help improve the appearance of dark scenes in a dark room. There are also a few virtual overlays, including:
The physical controls consist of a single joystick, much better than the OMEN 27.
We tested the 24.5" OMEN X 25f, which is one of many monitors in the OMEN X lineup. There is also a true G-SYNC version, known as the OMEN X25, which hasn't been released yet. We expect it to have different ports, but otherwise perform similarly to the version we've tested.
This monitor is not to be confused with the HP OMEN 25 (non-'X'), which has a 144Hz refresh rate, and isn't certified as NVIDIA G-SYNC Compatible.
If someone comes across a different type of panel or if their OMEN X 25f doesn't correspond to our review, let us know and we will update the review. Note that some tests such as gray uniformity may vary between individual units.

The HP OMEN X 25f we reviewed was manufactured in April 2019.
The BenQ Zowie XL2540 is a bit better than the HP OMEN X 25f. The XL2540 has better ergonomics and an optional black frame insertion feature to further improve the appearance of motion. The X 25f has a faster response time, but this isn't a very noticeable difference.
The HP OMEN 27 is slightly better than the HP OMEN X 25f. The 25f has a faster refresh rate, but the difference in response time is minor, and the 25f has a lower native resolution and smaller screen size than the OMEN 27. The X 25f has better black uniformity and it supports FreeSync, whereas the OMEN 27 supports G-SYNC.
The ViewSonic XG2402 and the HP OMEN X 25f are very similar overall, and the best one depends on your needs. The ViewSonic is better if you need a more adjustable stand, as it has better ergonomics and can be rotated to a portrait orientation. The OMEN X has slightly better motion handling, though, so it might be better for some people.
The AOC AGON AG271QX is a bit better than the HP OMEN X 25f. The AOC has a slower refresh rate, but this has very little impact on the overall appearance of motion. The AOC has better ergonomics, as it can swivel, and can be rotated to a portrait orientation. The AOC also has a higher resolution screen and more screen area, so it's a bit better for multitasking and allows you to see more fine details in your favorite games.
The HP OMEN X 25f is slightly better than the ASUS VG248QE. The HP has a faster refresh rate, although there is very little difference between the response times. The X 25f also supports FreeSync variable refresh rate technology, whereas the ASUS VG248QE doesn't support any VRR technology.
