The HP OMEN X 27 is a good 1440p monitor with great gaming performance. It has an impressive 240Hz refresh rate and an outstanding response time, resulting in exceptionally clear motion with no noticeable motion artifacts. It also has excellent low input lag, for an extremely responsive gaming experience.

Unfortunately, it isn't very versatile as, like most TN monitors, the image degrades when viewed at an angle, and it has a low contrast and bad black uniformity. This monitor also has a limited range of ergonomic adjustments, so it might be difficult to place in an ideal viewing position.

Our Verdict

7.5 Mixed Usage

The HP OMEN X 27 is a good monitor for most uses. It's a great gaming monitor, with low input lag and a fast response time. The 27 inch, 1440p screen is great for watching videos or working, and it has great reflection handling. Unfortunately, the image degrades at an angle and it has limited ergonomics.

Pros
  • Outstanding response time.
  • Excellent low input lag.
Cons
  • Image degrades at an angle.
  • Low contrast ratio.
7.3 Office

Decent monitor for office use. The 27 inch, 1440p screen is great for multitasking, and it has excellent low input lag. Unfortunately, the image degrades when viewed at an angle, and it has a limited range of ergonomic adjustments.

8.3 Gaming

This is a great gaming monitor. It has an extremely fast response time and fast refresh rate, resulting in clear motion with very little blur. It also has impressive low input lag, and it supports FreeSync, for a nearly tear-free gaming experience. Unfortunately, it has limited ergonomics, so it might be difficult to place in an ideal viewing position.

7.4 Multimedia

Decent monitor for multimedia. The 27 inch, 1440p screen is great for watching videos, and it has impressive low input lag. The HP OMEN X27 has great reflection handling and good SDR peak brightness, so glare shouldn't be an issue. Unfortunately, the image degrades at an angle, so it isn't great for watching videos with a group of friends, and it doesn't look as good in a dark room.

7.4 Media Creation

The HP OMEN X 27 is a decent monitor for media creation. The 27 inch, 1440p screen allows you to see more of your project at once, and it has outstanding low input lag. Unfortunately, the image degrades at an angle, and it has a limited range of ergonomic adjustments.

6.8 HDR Gaming

This is a decent monitor for gaming in HDR, mainly due to its great gaming performance. It has outstanding low input lag and an outstanding response time. Unfortunately, it has a low contrast ratio, bad black uniformity, and the local dimming feature isn't very effective. Although it can display a wide color gamut, it can't get very bright in HDR.

The stand has a good height adjustment range and a great tilt range. It can't swivel, and can't be rotated to portrait orientation, though, which might disappoint some users. If you need a monitor with better ergonomics, check out the ViewSonic Elite XG270.

Back

The back of the HP OMEN X 27 looks identical to the other OMEN monitors we've tested. It has a clean look, but only basic cable management. There's a quick-release on the back, and it can be VESA mounted using the included mounting bracket.

Just like the HP OMEN 27 and the HP OMEN X 25f, the HP OMEN X 27 has excellent build quality. The stand is made of metal and feels well-built, and although the panels are made of plastic, they have a premium feel to them.

Like most TN monitors, the HP OMEN X 27 has mediocre contrast. This causes blacks to look gray and is especially noticeable in a dark room. Unfortunately, the local dimming feature is ineffective at noticeably improving contrast.

The optional local dimming feature is bad, but it isn't as bad as most monitors we've tested. It does a good job dimming dark areas on the screen, but due to the limited number of zones, it can only dim relatively large portions of the screen. Some transitions are slow, causing a glowing trail behind fast-moving objects.

Unfortunately, the HP OMEN X 27 has mediocre peak brightness in HDR. Small, bright objects in some scenes don't stand out the way they should. We measured HDR peak brightness with the 'HDR Standard' mode, with local dimming enabled, before calibration.

Unfortunately, this monitor has bad black uniformity. There is significant clouding throughout the screen, but very little backlight bleed, which is good. The local dimming feature is effective at dimming some areas of the screen, but due to the limited number of zones, it can't dim very tightly around the test cross.

Mediocre HDR color volume. It's limited by the low native contrast ratio and limited HDR color gamut.

The HP OMEN X 27 has an incredibly fast response time, resulting in clear motion with almost no blur behind fast-moving objects, and no noticeable motion artifacts. There are four overdrive settings; we recommend 'Level 2', as it delivers the fastest response time with almost no overshoot. Level 3 is slightly faster, with an 80% response time of 1.9ms and a 100% response time of 4.6ms, but there is some overshoot, causing noticeable ghosting in some transitions. Level 4 has significant overshoot in many transitions, and we don't recommend it.

The HP OMEN X 27 has outstanding low input lag, great for a responsive gaming experience. When gaming at the native refresh rate and resolution, the input lag is one of the lowest we've ever measured and is great for even the most demanding gamers. The 60Hz input lag is a bit higher than average, which might be disappointing for some console gamers.
