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 natively supports AMD's FreeSync variable refresh rate technology, 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.

Our Verdict

7.0 Mixed Usage

The HP OMEN 27i is a good monitor for most uses but is 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 and 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.

Pros
  • Image remains accurate at an angle.
  • Excellent build quality.
  • Outstanding response time.
Cons
  • Low contrast ratio.
7.7 Office

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 won'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 it in an ideal viewing position.

Pros
  • Image remains accurate at an angle.
  • Excellent build quality.
  • Outstanding response time.
Cons
  • Low contrast ratio.
  • Disappointing accuracy out of the box.
7.8 Gaming

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 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.

Pros
  • Image remains accurate at an angle.
  • Excellent build quality.
  • Outstanding response time.
Cons
  • Low contrast ratio.
6.7 Media Consumption

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 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 has disappointing accuracy out of the box.

Pros
  • Image remains accurate at an angle.
  • Excellent build quality.
  • Outstanding response time.
Cons
  • Low contrast ratio.
  • Disappointing accuracy out of the box.
  • Doesn't support HDR.
7.2 Media Creation

The HP OMEN 27i is a decent monitor for media creation. The large, high-resolution screen makes seeing more of your work at once easier, 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.

Pros
  • Image remains accurate at an angle.
  • Excellent build quality.
  • Outstanding response time.
Cons
  • Low contrast ratio.
  • Disappointing accuracy out of the box.

Differences Between Sizes And Variants

We tested the 27" OMEN 27i, the only size available. We've also tested a few other HP OMEN monitors.

If someone comes across a different type of panel or their HP OMEN 27i doesn't correspond to our review, let us know, and we'll update the review. Note that some tests, like the gray uniformity, may vary between individual units.

Model Size Refresh Rate Resolution
OMEN 27i 27" 165Hz QHD(2560x1440)
OMEN 27 27" 144Hz QHD(2560x1440)
OMEN X 27 27" 240Hz QHD(2560x1440)

The model we tested was manufactured in June 2020.

Compared To Other Monitors

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.

LG 27GL850-B/27GL83A-B

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.

Dell S2721DGF

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. 

ASUS TUF VG27AQ

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.

HP OMEN 27c

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.

HP OMEN 27

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.

LG 27GL83A-B

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 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 HP OMEN 27i is extremely well-built. The stand is solid, made of metal, and supports the monitor well. The display is made of good-quality plastic; we didn't notice any gaps or loose panels.

The HP OMEN 27i has okay ergonomics but can't swivel. For a similar monitor with better ergonomics, check out the ASUS TUF VG27AQ.

The back of the monitor has a straightforward 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.

Also, it can be VESA mounted, but it's very important to make sure that your mounting bracket can rotate at least 45°, as the mounting holes are on an angle.

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 better contrast, check out the HP OMEN 27c.

macOS Compatibility

The HP OMEN 27i works well with macOS using an HDMI connection. During testing, we tried three different DisplayPort to USB-C cables, and our MacBook didn't recognize the monitor with any of them, so we had to use HDMI. With that, you don't get VRR, and the refresh rate is limited to 144Hz, but there aren't any obvious issues. Like most monitors, windows return to their original position when waking a MacBook up from sleep, but not when you open the lid after it was closed.
