The HP OMEN 27 is an LCD QHD monitor with a TN panel. It has decent picture quality and is more suitable for brighter environments as it can get bright and can handle reflections well. It has excellent motion handling with support for G-Sync variable refresh rate and black frame insertion to improve motion quality and clarity. Unfortunately, the best picture is reserved for those sitting right in front, and the low native contrast ratio along with the bad black uniformity make dark room performance disappointing.
The design of the HP OMEN 27 is good. The stand provides the monitor with stability and the entire construction feels sturdy. The ergonomics will give you some trouble until you are able to position the monitor to your liking, and the thickness of the monitor, when placed on its stand, will not allow you to place it too close to the wall. The monitor has a neat LED light feature to create a nice ambiance.
The back of the monitor is plastic but feels more premium. There is a vent along the top edge to help dissipate heat. The stand has a hook at the top for your headphones and a loop near the base that helps cable management.
The border around the monitor is metallic with average thickness and a very thin bezel. The screen has a small gap between the bezel and where the pixels start. This is similar to other monitors we've tested like HP 22CWA.
The monitor looks thick when attached to its stand. If you wish to VESA mount it, you must first attach the included VESA adaptor. The adapter attaches to the monitor using the same metal mounting socket that the monitor uses to attach to the stand (shown here). Unfortunately, when you attach the adapter, the entire setup is quite thick and the monitor still protrudes quite a lot from the VESA mount.
Mediocre picture quality on this HP OMEN 27. The disappointing contrast, terrible black uniformity, and bad viewing angles make this monitor a poor choice for darker environments or for viewing from the side. On the other hand, the great brightness, very good reflection handling, and excellent color gamut make this monitor's picture quality more suitable for brighter rooms.
The OMEN has a disappointing native contrast. This is expected for a monitor with a TN panel. Its native contrast is very similar to that of ASUS PB277Q and it is in the middle of the list of TN monitors.
The HP OMEN 27 does not have a local dimming feature. The video is for reference only.
The SDR Peak brightness of this HP OMEN 27 monitor is great. The monitor is suitable for brighter rooms as it can fight glare and its brightness is consistent among the bright window sizes. It is one of the highest brightness levels we have measured so far, similar to other TN monitors like the Acer GN246HL or the Dell S2417DG.
HDR is not supported.
TN monitors are notorious for their bad viewing angles, so the disappointing performance of the HP OMEN 27 is no surprise. At a few degrees off center, the black level raises and the image turns grayish, while a few degrees more and the colors start to shift. This is a very similar behavior to the ASUS VG248QE which also has a TN panel.
The situation is slightly better with the vertical viewing angles. When you look from above the monitor keeps its image quality for slightly higher off-center angles. However, when you look from below the image loses accuracy at very small angles. This causes the top edge of the screen to look darker when you sit close to the screen.
This is one of the best results for TN monitors we've tested so far, second only to Dell S2417DG.
The HP OMEN 27 has good gray uniformity, especially in the darker gray shades. There are some obvious uniformity issues but it is unlikely that you will spot any dirty screen effect. The image shows the top edge darker than the rest of the screen. This is because of the bad viewing angle from below, rather than a uniformity issue. This behavior is very similar to the Dell S2417DG.
Bad black uniformity. One of the worst black uniformity performances we have tested so far and the worst among TN panels just after Dell S2417DG. Backlight bleed is evident everywhere in the screen.
Great out of the box color accuracy for the HP OMEN 27. The Picture mode that we used is 'Custom RGB' since it allows for changing the white balance. However, the 'Native', 'Custom RGB', 'Gaming - Racing' and 'Gaming - FPS' Picture modes were all nearly identical out of the box.
The out of the box white balance dE is well below our threshold of 3, so it is very hard to spot the gray inaccuracies. The Color dE is also below our threshold of 3, but in this case, color inaccuracies will be easier to spot, although most people still won't notice them. The color temperature is very close to our target of 6500 K, and the average gamma is spot on our 2.2 target, although the curve does not quite follow our target curve. Dark shades look slightly darker whereas brighter colors are a little over saturated.
Excellent color accuracy post calibration for the HP OMEN 27, similar to the Dell S2716DG. The white balance dE and the color dE were brought down to below 1 and thus color inaccuracies are almost impossible to spot. The gamma curve now follows our target curve more closely even though the average value is slightly off our 2.2 target.
Note: The contrast wasn't listed in the OSD, but it was changeable via DDC.

s.RGB Picture Mode: Custom RGB (calibrated)
Adobe RGB Picture Mode: Custom RGB
Excellent coverage of the s.RGB colorspace for the HP OMEN 27. On the other hand, the wider Adobe RGB colorspace used by professionals in graphics and publishing has limited coverage which might not be enough for those editing photos in the Adobe RGB color space.
s.RGB Picture Mode: Custom RGB
Adobe RGB Picture Mode: Custom RGB
Excellent coverage of the s.RGB color volume mainly due to the excellent color gamut. On the contrary, the coverage of the Adobe RGB color volume that is used in the publishing media is not enough for those professionals out there.
HDR is not supported.
HDR is not supported.
No image retention is visible on this monitor. Even after 10 minutes of a high contrast static image, no retention is visible.
Even though the overall gradient performance is decent, this HP OMEN 27 has banding in most dark colors.
This is the worst performance of all the monitors we've tested until now.
Update 01/07/2019: The gradient score has been updated (6.8 -> 8.4), as it was scored incorrectly at the time of the review. The gradient photo is still valid, and shows good overall performance, with a few areas of bad banding in dark green and gray.
Excellent score in our color bleed test for the HP OMEN 27. There is some minor color bleeding when the monitor displays large areas of uniform color. In our test, this is depicted in the vertical columns image.
Excellent motion handling for the HP OMEN 27. The monitor has a very fast response time and a very short motion blur. The monitor does not use PWM to reduce brightness but it has the option to introduce flicker if you want to make the image crisper. The refresh rate is 144Hz and can be boosted even higher, and that, combined with G-Sync support, will please most gamers.
Excellent performace and almost instantaneous response time for the HP OMEN 27, just like the Dell S2716DG.The best results were obtained with Response Time set at 'Level 3 (default)' where the monitor has a little overshoot but it's barely noticeable in person. This means that there is very liitle blur on the screen when you move the mouse quickly or you display other fast action.
Excellent flicker performance on this HP OMEN 27, almost identical to Dell S2716DG. The backlight dims without flickering. There is some very small wobble but it shouldn't be visible.
The monitor has an option to introduce flicker to clear blur through NVIDIA ULMB which is the name of G-Sync's BFI implementation. The frequencies at which you can do it are: 120 Hz, 100 Hz and 85 Hz.
There is also a Pulse Width setting that changes the duration of each backlight pulse, similar to that of other G-Sync monitors like the Dell S2716DG. This makes motion appear even more clear but also decreases brightness even more.
There is more overshoot when BFI is enabled, and the overshoot cannot be reduced. You can see this in the BFI photo where there is more visible overshoot than the Response Time photo. You can not reduce overshoot as the Response Time section of the menu is disabled when BFI is on.
Excellent performance of the HP OMEN 27 on our refresh rate test, at par with rival monitor Dell S2716DG. The monitor has a very fast refresh rate of 144Hz that can be boosted to 165Hz through the menu. It has a very good support of the G-Sync variable refresh rate and will keep those gamers with NVIDIA cards happy.
The HDMI port is limited to 60 Hz and has no G-Sync support.
The HP OMEN 27 has an excellent low input lag that can satisfy most competitive gamers. The QHD resolution is very good for a 27-inch monitor and will provide you with enough detail to work on.
Lowest input lag possible at the center of the screen, when the monitor is displaying an alternative resolution at its native refresh rate. The non-native resolution tested depends on the native resolution of the monitor, following this pattern unless otherwise specified in the Input Lag text:
|Native Resolution||Non-Native Resolution Tested|
BFI Frequency Tested: 120 HzOver DisplayPort the only supported resolutions are 640x480, 800x600, 1024x768 and 2560x1440, and only 2560x1440 is capable of 144 Hz; this isn't usually a problem though because most graphics cards will upscale to 2560x1440 without you even knowing.
The HP OMEN 27 has a great QHD resolution which allows it to display a good amount of detail on its 27-inch screen. This is the same as rival monitor Dell S2716DG.
This monitor leaves you with mixed feelings regarding its features. On one hand it does not include any speakers or HDR10 support and unfortunately, the OSD is unintuitive and hard to use. On the other hand, there are some goodies hidden in the menus but they are not easy to find. The navigation buttons are also hidden out of sight and are hard to find, and their layout makes it difficult to tell them apart.
Here are some monitor features that you might find useful:
The buttons are very hard to use as they're on the back of the monitor and they can't be seen from the front. You have to reach underneath the monitor blindly and since they're flush with the back of the monitor, they can be hard to find. Furthermore, the buttons are wide with little space separating them so they're hard to tell apart when you're reaching blindly. And this, of course, leads to pressing the wrong button fairly often. Not one of the better control schemes we've seen on monitors so far.
We tested the 27" model (OMEN 27). The other models shown in the table below have different specs and our review isn't representative of them.
If someone comes across a different type of panel or if their HP OMEN 27 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 August 2017.
The Dell S2716DG is a bit better than the HP OMEN 27 mainly due to the better ergonomics that allow you to position the monitor to your liking. Other than that, the two monitors perform very similarly.
The ASUS ROG PG279Q is a significantly better monitor than the HP OMEN 27 in almost every usage. The ASUS has an IPS panel and thus better viewing angles than the TN panel HP. Also, the ASUS has better uniformity and better contrast ratio and this is great for many different usages.
The Samsung CHG70 is a much better monitor than the HP OMEN 27 in almost every usage. The Samsung has better contrast and overall better dark room performance. It also supports HDR and delivers better picture quality than the HP. The HP, on the other hand, has TN panel and a very fast pixel response time that leaves very small blur trail. Both monitors support variable refresh rate but through different implementations. The HP supports G-Sync whereas the Samsung supports FreeSync. So be careful to have a matching graphics card or gaming console.
The AOC AGON AG271QX is better than the HP OMEN 27. The AOC AGON AG271QX has better ergonomics and this is very useful no matter the usage. It also has better black uniformity that improves the quality of blacks in a dark room. On the other hand, the HP supports the black frame insertion feature that helps reduce blur during fast action.
