The HP OMEN 27i is a great gaming monitor. It has an outstanding response time, resulting in clear motion when gaming, as well as low input lag for a responsive gaming experience. Although it supports AMD's FreeSync variable refresh rate technology natively, it's also certified for NVIDIA's G-SYNC compatible technology. It's well-built, with a solid metal stand that supports it well, easy-to-access inputs, and RGB bias-lighting. The 27" 1440p screen is great for multitasking and for gaming, and the IPS panel delivers wide viewing angles and an outstanding SDR color gamut. Unfortunately, the stand has disappointing ergonomics, and like all IPS monitors, it has a low contrast ratio, so blacks look gray in a dark room. It's also not very accurate out-of-the-box, so media creators might prefer to look elsewhere.
The HP OMEN 27i is a good monitor for most uses, but it's best-suited for gaming. The high peak brightness and good reflection handling make it a good choice for the office. It has an outstanding response time, low input lag, and it supports FreeSync, great for gaming. On the other hand, the low contrast ratio and disappointing accuracy out-of-the-box make it only a decent choice for multimedia or content creators.
The HP OMEN 27i is a good monitor for office use. The 27" 1440p screen is great for multitasking. It has good peak brightness and good reflection handling, so glare shouldn't be an issue. The image remains accurate when viewed at an angle, so you can easily share your screen with someone else. Unfortunately, the stand has a limited range of motion, so it might be difficult to place in an ideal viewing position.
The HP OMEN 27i is a great gaming monitor. It has an outstanding response time, so there's very little blur behind fast-moving objects. It also has excellent low input lag for a responsive gaming experience, and it supports FreeSync variable refresh rate technology. On the other hand, this monitor isn't a great choice for late-night gaming, as it has a low contrast ratio and poor black uniformity.
The HP OMEN 27i is a decent monitor for multimedia. It has wide viewing angles, good peak brightness, and good reflection handling, so it's great for watching videos with a group of friends, even in a bright room. On the other hand, it has low contrast and poor black uniformity, so it's not a great choice for watching videos in a dark room, and it has disappointing accuracy out-of-the-box.
The HP OMEN 27i is a decent monitor for media creation. The large, high-resolution screen makes it easier to see more of your work at once, and the wide viewing angles are great for sharing the screen with clients. It has excellent gray uniformity and outstanding gradient handling, with almost no noticeable banding. Unfortunately, it has disappointing accuracy out of the box, which may be an issue for some content creators.
The HP OMEN 27i doesn't support HDR.
The HP OMEN 27i has a very similar design to the HP OMEN 27, but it's been updated a bit, with slimmer bezels and a sturdier stand. The back of the monitor has a unique design, with easy-to-access inputs and a nice RGB backlight feature. It has only basic cable management, but it's extremely well-built.
The stand is slim but solid, and it supports the monitor extremely well.
Unfortunately, the HP OMEN 27i has disappointing ergonomics, as it can't swivel, and can't be rotated to portrait orientation. On the other hand, it has a great height adjustment range and a great tilt range. For a similar monitor with better ergonomics, check out the ASUS TUF VG27AQ.
The back of the monitor has a very simple design, but it looks great. The inputs are angled to the sides, making them very easy to access, and there's an RGB bias lighting feature around the box that houses the monitor's inputs and electronics. Cables can be routed through a hole in the stand, providing very basic cable management.
The HP OMEN 27i can be VESA mounted, but it's very important to make sure that your mounting bracket can be rotated at least 45°, as the mounting holes are on an angle. HP has posted a video showing how to mount it.
The borders around the monitor are very thin on three sides, making this a great choice for a multi-monitor setup.
When attached to the stand, the HP OMEN 27i is a bit thicker than most similar monitors we've tested. Unlike the HP OMEN 27, the mounting arm has to be removed to VESA-mount the display, so it's quite a bit thinner when mounted.
The HP OMEN 27i is extremely well-built. The stand is solid, made of metal, and it supports the monitor well. The display is made of good quality plastic, and we didn't notice any gaps or loose panels.
Typical for IPS panels, the HP OMEN 27i has a low contrast ratio, so blacks look gray in a dark room. In a brighter viewing environment, this isn't as noticeable. HP advertises a typical contrast ratio of 1000:1 for this display, so these results are a bit on the low side, but this varies between units. If you want a monitor with a VA panel for a better contrast, then check out the HP OMEN 27c.
There's no local dimming feature on this monitor. This video is provided for reference only.
Very good SDR peak brightness, this monitor can easily overcome glare in a brighter viewing environment. It's also extremely consistent, with no noticeable change in brightness with different content.
The HP OMEN 27i doesn't support HDR.
Unlike the TN panel used on the HP OMEN 27, the HP 27i uses an IPS panel, and has excellent horizontal viewing angles. This is great if you often share your screen with someone else sitting nearby, as the image remains accurate even when viewed off-center.
The HP 27i has decent vertical viewing angles. This is important if you often share your screen with someone standing next to you, as you can be confident that they'll see the same thing you do.
Excellent gray uniformity overall. The sides of the screen are a bit darker than the center, especially the left-hand side of our unit, but this can vary a bit between units. If you have this monitor, let us know in the discussions if you notice the same thing.
Unfortunately, the HP OMEN 27i has poor black uniformity. There's noticeable backlight bleed on our unit, especially from the bottom left corner, and the entire screen is a bit cloudy. Black uniformity varies between units, so if you have this monitor let us know how it looks.
Sub-par accuracy out of the box. Although gamma follows the sRGB target curve well, there are noticeable errors in the white balance and most colors. There's also no sRGB mode, which is a bit disappointing. Note that the out-of-the-box accuracy can vary between units. If you want a monitor with better accuracy out of the box, check out the Lenovo Legion Y27q-20.
After calibration, the HP OMEN 27i is much more accurate. The remaining inaccuracies in the white balance aren't noticeable, and except for highly saturated blues, colors are reproduced accurately.
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 HP OMEN 27i has an impressive SDR color gamut. It can display the entire sRGB color space used by most web content, and it even has great coverage of the wider Adobe RGB color space, making it a great choice for content creators.
Outstanding SDR color volume. The HP OMEN 27i is limited by the low contrast ratio, as it can't display dark, saturated colors. Like most LCD monitors, highly saturated blues aren't as bright as other colors, but this shouldn't be very noticeable.
This monitor doesn't support HDR. If you want a similar monitor that does, check out the LG 27GN880-B.
This monitor doesn't support HDR.
There are no signs of temporary image retention on our unit. This can vary between units though, so let us know if you have this monitor and have seen any signs of image retention.
Although this monitor doesn't support HDR, it can accept a 10 bit signal, but only if the refresh rate is below 120Hz. When sending a 10 bit signal, gradients are extremely clean, with almost no noticeable banding.
While there is some very slight color bleed, it's not at all noticeable.
Very good reflection handling. Combined with the high peak brightness, glare shouldn't be an issue even in a brighter room.
The HP OMEN 27i has decent text clarity, but it's recommended to enable ClearType, as seen in the diagonal and curved lines in the top photo.
|Overdrive Setting||Response Time Chart||Response Time Tables||Motion Blur Photo|
The HP 27i has outstanding response time at the maximum refresh rate, resulting in a very short blur trail behind fast-moving objects. Unfortunately, this isn't as good as the HP OMEN 27 or the HP OMEN X 27.
There are four pixel overdrive settings, but we recommend the lowest setting, level 1. Level 2 is faster, but there's more noticeable overshoot. Higher settings aren't recommended, as the amount of overshoot increases drastically.
|Overdrive Setting||Response Time Chart||Response Time Tables||Motion Blur Photo|
Outstanding response time at 60Hz, with very little blur behind fast-moving objects, much better than the ASUS TUF VG27AQ. Like at the maximum refresh rate, the level of overdrive can be adjusted, but we still recommend the Level 1 setting. Higher settings are slightly faster, but unlike at the maximum refresh rate, even the Level 2 setting has significant overshoot.
The backlight is completely flicker-free, which is great.
Unlike the HP OMEN 27, this monitor doesn't have an optional Black Frame Insertion feature.
This monitor's high refresh rate is great for gaming or desktop use. The HP OMEN 27i supports FreeSync variable refresh rate technology, but it's also certified by NVIDIA to work with their G-SYNC Compatible technology. Although FreeSync works over both HDMI and DisplayPort, NVIDIA's G-SYNC Compatible mode only works over DisplayPort with this monitor.
Outstanding low input lag, resulting in a very responsive gaming experience. 60Hz input lag is a bit higher than most similar monitors, but this isn't a noticeable difference.
The 27", 1440p screen is great for multitasking. It also allows you to see more fine details in your favorite games and maintain high frame rates, even if you don't have a top-of-the-line graphics card.
There are a few additional features, including a virtual crosshair overlay and frame counter, both of which are pretty common on gaming monitors. The HP OMEN 27i also has a controllable RGB backlight around the inputs section on the back.
We tested the 27" OMEN 27i, which is the only size available. We've also tested a few other HP OMEN monitors.
If someone comes across a different type of panel or if their HP OMEN 27i doesn't correspond to our review, let us know and we will update the review. Note that some tests such as the gray uniformity may vary between individual units.

The model we've tested was manufactured in June 2020.
The HP OMEN 27i is a great gaming monitor with a fast refresh rate. There are quite a few similar displays on the market, including the ASUS TUF VG27AQ and the ASUS ROG Swift PG279QZ, but most of them are more expensive. See our recommendations for the best gaming monitors, the best 27" monitors, and the best 144Hz monitors.
The HP OMEN 27i and the Dell S2721DGF are very similar. They're both 27 inch IPS monitors with a 1440p resolution and 165Hz refresh rate. The Dell has better response times to deliver clearer motion with less blur trail behind fast-moving objects. It also has significantly better ergonomics because it can swivel and rotate to portrait mode, and it supports HDR.
The ASUS TUF VG27AQ is much better than the HP OMEN 27i for most users. The ASUS has much better ergonomics, so it's easier to place it in an ideal viewing position. The ASUS also supports HDR, and it has an optional Black Frame Insertion feature. While the ASUS is slightly better overall for gaming, some gamers might prefer the HP, as it has a much faster response time when gaming on a console at 60Hz.
The HP OMEN 27i and the HP OMEN 27c are both great gaming monitors with a few differences between them. They use different panels, as the IPS panel on the 27i provides wider viewing angles, and the VA panel on the 27c has better contrast. Even though the 27c has a higher 240Hz refresh rate, motion looks smoother on the 27i because there's less black smearing. The 27c supports HDR and has a local dimming feature, both of which the 27i doesn't have, but it doesn't add much as the local dimming on the 27c is terrible. They're built almost the same way, but the 27c has a curved screen while the 27i is flat.
The HP OMEN 27i and the LG 27GL83A-B are extremely similar overall. The HP has much better build quality, as well as an RGB bias-lighting feature. On the other hand, the LG supports HDR, and it's much more accurate out of the box. Other than that, there's really not much difference between these two monitors.
The HP OMEN 27i is better than the HP OMEN 27 for most users. The 27i has better viewing angles, better reflection handling, and better uniformity. Some gamers may prefer the older OMEN 27 though, as it has a faster response time, and it supports NVIDIA G-SYNC variable refresh rate technology.
The LG 27GL850-B and the HP OMEN 27i perform very similarly, but the LG is slightly better overall. The LG supports HDR, although this doesn't add much. The LG has a slightly faster response time, but there's also more overshoot in our recommend 'Fast' overdrive setting. The LG is also more accurate out of the box. On the other hand, the HP is better-built, with excellent build quality.
