Design and Build
Backlit design of the HP Omen 27k gaming monitor.
The Omen 27k sports a practical, minimalist design with a black plastic casing, similar to monitors like the Gigabyte M32U. A distinguishing feature is the customizable bias lighting on the back, adding a subtle ambient glow, particularly noticeable when placed against a wall. HP’s branding is understated, with a small Omen logo on the bottom bezel and the signature Omen triangle on the base. The sturdy metal base provides stable support without consuming excessive desk space.
The stand offers tilt, pivot, and height adjustments, enhancing ergonomic flexibility. While swivel functionality is absent, the inclusion of a 100mm x 100mm VESA mount allows for monitor arm compatibility.
Connectivity options on the HP Omen 27k.
A notable drawback is the lack of cable management. Cables connect from the bottom and dangle visibly, detracting from the otherwise clean aesthetic. The low placement of the ports exacerbates this issue. Even a simple cable hook would significantly improve cable organization.
Feature Set

The Omen 27k surpasses expectations for a budget 4K gaming monitor with its comprehensive feature set. Beyond the expected 4K resolution and high refresh rate, HP includes several valuable additions.
The USB-C port with DisplayPort Alt Mode allows seamless connectivity with laptops and devices like the Steam Deck. The absence of power delivery limits single-cable solutions, but the integration with the built-in KVM switch is a significant advantage. This feature enables shared peripherals across multiple sources, simplifying multi-device setups.
Built-in speakers, while not audiophile-grade, provide a convenient backup when dedicated audio solutions are unavailable.
Connectivity and On-Screen Display

The Omen 27k offers a USB-C input alongside standard connectivity options, including DisplayPort 1.4 and two HDMI ports. Crucially, only one HDMI port supports HDMI 2.1 for full 4K resolution and refresh rate; the other is HDMI 2.0, potentially limiting performance. For optimal output, users are restricted to one HDMI 2.1 and one DisplayPort 1.4 connection.
Monitor controls are managed via buttons on the back, navigating a functional but visually dated on-screen display (OSD). Despite its appearance, the OSD provides extensive customization options, including eight color profiles and gain adjustments for red, green, and blue primaries, enabling basic monitor calibration.

Image Quality and Performance
Color gradient display test on the HP Omen 27k.
The Omen 27k delivers impressive image quality for its price, boasting a bright IPS panel with accurate color reproduction. Measured peak brightness exceeds the advertised 400 nits, reaching 436 nits, while the contrast ratio also surpasses the standard 1000:1 for IPS panels. Color accuracy is exceptional, outperforming some factory-calibrated monitors.
SDR performance is excellent. However, the DisplayHDR 400 certification limits the HDR experience. While the monitor achieves decent brightness, it falls short of true HDR impact. The claimed 10,000,000:1 dynamic contrast ratio is misleading, relying on a limited eight-zone local dimming implementation.

While local dimming is a welcome feature at this price point, it doesn’t deliver the dramatic contrast improvements seen in mini-LED displays.
Gaming Performance

The Omen 27k’s 144Hz refresh rate, FreeSync Premium, and G-Sync Compatible certifications ensure smooth and responsive gameplay. The 4K resolution on a 27-inch screen provides exceptional pixel density and sharpness. However, the IPS panel’s inherent response time limitations require careful overdrive setting adjustments. While the highest overdrive level aims for a 1ms response time, it introduces significant ghosting. Lower overdrive levels offer a better balance between speed and image clarity.

The Omen 27k is well-suited for immersive gaming experiences, prioritizing cinematic visuals over competitive performance. Users seeking higher refresh rates for fast-paced gameplay might consider lower resolution alternatives. A powerful PC is essential to fully leverage the monitor’s 4K capabilities.

The Omen 27k exemplifies the progress in gaming monitor technology, making 4K gaming more accessible than ever.
