HP Omen 27i Monitor Tempts TN Gamers With 165Hz IPS


The HP Omen 27i input lag amounts to just ~3ms, which makes for imperceptible delay between your actions and the result you see on the screen.

Further, the response time speed is exceptional as well. There are four pixel response time overdrive settings, ranging from Level 1 to Level 4.

At 165Hz, we recommend using Level 2 as it efficiently prevents trailing behind fast-moving objects without adding too much overshoot. However, at lower refresh rates, Level 1 works better as it has less overshoot than Level 2.

If you are using a variable refresh rate (VRR), be it AMD FreeSync or NVIDIA G-SYNC Compatible, and your frame rate is fluctuating a lot, the Level 1 setting provides more consistent performance across the entire refresh rate range since it still looks very good at 165Hz/FPS.

The best option (Level 1 or Level 2) will most likely depend on your personal sensitivity to ghosting and/or inverse ghosting as well as on the frame rate you can maintain in certain games, so you should try both modes yourself and see what works best for you.

The HP Omen 27i monitor is certified as G-SYNC Compatible by NVIDIA, so you can expect flawless VRR performance up to 165FPS.

The supported VRR range is 48-165Hz over DisplayPort for AMD/NVIDIA cards and 48-144Hz over HDMI for AMD cards.

With the Xbox One and Series consoles, the range is 48-120Hz, and the monitor supports the 1440p 120Hz mode.

Below 48Hz/FPS, LFC (Low Framerate Compensation) continues to keep tearing at bay via frame rate multiplication (47Hz -> 94FPS, etc.).


The OSD (On-Screen Display) menu of the HP Omen 27i can be accessed via the directional joystick placed at the rear of the monitor.

Besides the standard image adjustment tools, such as brightness, contrast, and color temperature, there are a few noteworthy gaming features, including various picture presets, an on-screen timer, crosshair overlays, and a refresh rate tracker.

The backlight of the monitor is flicker-free, which in addition to the low-blue light filter mode and the matte anti-glare screen coating, allows for a comfortable viewing experience even after prolonged use of the screen.

Design & Connectivity

HP Omen 27i Monitor Design

The HP Omen 27i boasts a sleek and sturdy design with a height-adjustable stand up to 130mm, tilt by -5°/20°, and VESA mount compatibility (100x10mm).

It also has customizable (different colors and patterns) RGB lighting at the back, which can be useful as the light falls on your desk and can, for instance, illuminate your keyboard in the dark.

Connectivity options include DisplayPort 1.2, HDMI 2.0, a headphone jack, and a dual-USB 3.0 hub (one upstream, two downstream ports).

Due to the DisplayPort 1.2 bandwidth limitations, you are limited to 8-bit color depth at 165Hz. For 10-bit color, you will need to reduce the refresh rate to 120Hz or resort to chroma subsampling.

Since there’s no noticeable difference between 8-bit and 10-bit color in most games, it’s not a particularly big issue.

Price & Similar Monitors

If you don’t care for the sRGB emulation mode or the virtually unnoticeable 15Hz difference, and you prefer the design of the Omen 27i, it’s worth considering – otherwise, the 27GP850 is an overall better monitor for the money.

Keep in mind that there are two more HP monitors with similar names, the HP Omen 27 (without the ‘i’ at the end), which uses a TN panel with inferior image quality and narrow viewing angles – and the HP Omen X 27 with a 240Hz TN panel.

Overall, the HP Omen 27i is an excellent gaming monitor.

It offers a crisp image quality with striking colors thanks to its 1440p IPS panel, while the rapid response time, low input lag, 165Hz refresh rate, and smooth VRR performance ensure a responsive gaming experience.

We only wish it had an sRGB emulation mode – if it did, we are sure it’d be a much stronger rival to the more popular LG 27GP850 thanks to its attractive design.
