27-inch FHD 180 Hz gaming monitor

The HP OMEN AV4K1AA-R is a 27-inch Full HD display running at 180 Hz with a 1 ms grey-to-grey response. It delivers 400 nits brightness, a 1000:1 contrast ratio and 16.7 million colours across 178-degree viewing angles. The edge-lit panel uses a 16:9 aspect ratio at 1920 by 1080 resolution.

Competitive players needing high refresh at 1080p

This monitor suits gamers who prioritise fluid motion at 180 Hz on a 27-inch screen. It is less suited for creators who require factory colour calibration, HDR certification or a wider colour gamut. Buyers wanting built-in speakers or USB hub connectivity should look elsewhere.

Adjustable stand and VESA 100 mounting

The stand provides height adjustment, pivot and tilt so the screen can be positioned for long sessions. An anti-glare coating reduces reflections in bright rooms. A 100 by 100 mm VESA pattern allows wall or arm mounting without extra brackets. DisplayPort and HDMI cables are the only bundled accessories.

Questions about this item

Does my graphics card need a DisplayPort or HDMI output to drive the 180 Hz panel?

Yes — the monitor accepts both DisplayPort and HDMI, so your GPU must provide at least one of those connectors to reach the 180 Hz refresh rate.

Will a VESA 100 x 100 mm arm I already own fit this screen?

The monitor uses the standard 100 x 100 mm VESA pattern, so any existing arm or bracket with that spacing will mount directly.

How can I confirm the panel is actually running at 180 Hz after I connect it?

Open your OS display settings or the GPU control panel and verify the refresh rate shows 180 Hz; the on-screen menu also reports the active timing.
