The HP Omen X 27 is one of the first 1440p 240Hz gaming monitors to be available on the market.
People who enjoy 240Hz gaming can now finally move past the lowly 1080p resolution and revel in crystal-clear details, provided they have the proper PC rig to sustain it.
Alas, the Omen X 27 uses a TN panel, so common drawbacks such as narrow viewing angles and inferior image quality are still present.
The HP Omen X 27 monitor sports a screen resolution of 2560×1440 which is for most people the ideal resolution for 27″ sized displays.
You get the perfect pixel-per-inch ratio of ~108 PPI (pixels per inch) resulting in vivid and crisp details as well as plenty of screen real estate without having to use any scaling.
Naturally, 1440p is also more demanding than 1080p.
If you want to get anywhere near 240FPS, you’ll need a high-end graphics card, and you shouldn’t expect to get such high frame rates in games other than the eSports titles.
Other panel-related specifications include a 300-nit peak brightness, a static contrast ratio of 1,000:1, true 8-bit color depth, 90% DCI-P3 color gamut, and HDR (High Dynamic Range) support.
While the colors are good for a TN panel display, they are still a far cry from color vibrancy found on equally-priced IPS or VA gaming monitors.
Further, the HP Omen X 27 can accept the HDR10 signal of compatible content, but it lacks proper display capabilities to notably improve the viewing experience.
HDR content gets a boost in peak brightness up to 400-nits, but the lack of 10-bit color depth, high contrast ratio, and color quality is evident. The display doesn’t even qualify for VESA’s entry-level HDR400 certification.
The backlight of the monitor is edge-lit and there’s a local dimming solution, however, there are only 16 dimming zones. Enabling local dimming will make blacks a bit darker, but due to the low contrast ratio, there’s an obvious lack of black depth and visibility of details in shadows.
What’s more, since there are only 16 dimming zones, they cannot quite keep up with fast-moving objects which will introduce noticeable trailing/glowing. So, for fast-paced gaming, make sure local dimming is disabled.
Overall, the image quality isn’t bad. There’s a notable improvement over the older 1440p 144Hz TN models such as the Dell S2716DG. However, don’t expect the IPS or VA levels of color and contrast quality due to the monitor’s specified wide color gamut, HDR support, and local dimming features.
These features are a bit misleading and unnecessary, but the image quality is decent for a TN panel while 1440p ensures crisp details without having to sacrifice CPU/GPU power for anti-aliasing.
While the image quality is a bit better as opposed to the previous-generation TN models, the 160°/170° viewing angles are still a bit of a problem.
As soon as you move and look at the screen from the sides or from below/above, the picture quality degrades. This isn’t an issue if you’re sitting directly in front of the screen, but it’s something you should have in mind.
Moving on, the HP Omen X 27 input lag performance is impressive with just below 3ms of delay at 240Hz which is imperceptible.
The response time speed is top-notch as well; you won’t encounter any prominent ghosting or trailing behind fast-moving objects.
There are four response time overdrive modes: Normal, Fast, Faster, Fastest. We recommend using either ‘Fast’ or ‘Faster’, as ‘Fastest’ introduces a lot of pixel overshoot.
Unfortunately, there’s no MBR (Motion Blur Reduction) technology of any sort available.
The HP Omen X 27 supports AMD FreeSync 2 HDR which provides a variable refresh rate (VRR) within the 48-240Hz/FPS (Frames Per Second) range for compatible graphics cards.
This technology effectively eliminates all screen tearing and stuttering with minimal input lag penalty (1-2ms). FreeSync works without any issues when used with compatible NVIDIA cards, even though the monitor isn’t certified as G-SYNC compatible by NVIDIA.
Note that the HP Omen X 27 display is not flicker-free. It uses PWM (Pulse-Width Modulation) to regulate brightness, and although the flicker is invisible to the human eye, those very sensitive to it may experience headaches after prolonged use.
Next to the power button, you will find four hotkeys for OSD (On-Screen Display) navigation, but no joystick which we would’ve preferred.
Luckily, HP has the exclusive Omen Command Center application which allows you to make all the important monitor adjustments there, among other things.
Useful gaming features include customizable crosshair overlays, an FPS counter, pre-calibrated picture presets (Gaming, Movie, Low Blue Light, etc), and customizable RGB lighting.
The RGB LED is facing the monitor’s stand, it’s subtle and actually practical, especially in the dark.
For the best image quality, we recommend using the ‘Native’ color temperature mode.
Design & Connectivity
The HP Omen X 27 1440p 240Hz gaming monitor has a fairly slim but sturdy design with ultra-thin bezels. It has a rather aggressive matte anti-glare screen coating which some users may find too grainy, but it’s tolerable.
Ergonomics include height adjustment up to 130mm, tilt by -3°/23°, and 100x100mm VESA mount compatibility via the provided adapter. You cannot swivel or pivot the screen.
Connectivity options include one HDMI 2.0 port, one DisplayPort 1.4 input, a dual-USB 3.0 hub, and a headphones jack. Note that HDMI 2.0 is limited to either 1440p 144Hz or 1080p 240Hz.
Price & Similar Monitors
The HP Omen X 27 price ranges from $600 to $650.
The only other 1440p 240Hz monitor currently available (not yet in the US) is the Lenovo Legion Y27GQ-25.
While the Lenovo has NVIDIA G-SYNC, it’s also significantly more expensive (~$1,000) and many users are complaining about its loud built-in fan.
So, if you want a 1440p 240Hz display, the Omen X 27 is definitely a more cost-effective option.
So, should you buy this monitor?
Well, for most people, we would recommend getting a 27″ 1440p 144Hz display with an IPS panel such as the LG 27GL850 instead.
It’s much cheaper and you get a lot better image quality and viewing angles while the performance is basically just as smooth since the jump from 144Hz to 240Hz is not nearly as noticeable as going from 60Hz to 144Hz – yet it’s significantly more demanding, especially at 1440p.
If, on the other hand, you want 240Hz as well as for your games to look better than they do at 1080p, and you have the budget to properly run 240FPS at 1440p, the HP Omen X 27 may not be the holy grail some have hoped for, but it will get the job done.
It’s certainly a better option than the 1080p 240Hz IPS models currently available including the Dell AW2720HF and the Acer XV273X which may offer better colors and wider viewing angles, but they have a lower resolution and the response time speed of their IPS panels simply isn’t fast enough for 240Hz.
