High-Speed Gaming Performance
The Q27G4XF is built with serious gaming in mind. It features a 180Hz refresh rate and an ultra-fast 1ms response time, minimising motion blur and ghosting during fast-paced gameplay. NVIDIA G-SYNC compatibility helps to synchronise the display with the graphics card output, reducing screen tearing and stuttering. HDR10 support further enhances the visual depth with richer contrast and more dynamic range in supported content.
Connectivity and Ergonomic Design
The monitor offers a practical set of connectivity options including one HDMI 2.0 port, one DisplayPort, and a headphone output. The ergonomic stand provides a wide range of adjustability, including height adjustment, tilt from -3 to 21 degrees, swivel up to 28 degrees in both directions, and a full 90-degree pivot for portrait orientation. A cable lock slot adds an extra layer of physical security in shared environments.

Good monitor at a great price!
I needed a second monitor for my home set up. This was on sale for Black Friday. I shose because of the rotating screen which meant I did not need a monitor arm. Worked out of the box Came with a DP & HDMI cable as well as an EU to UK plug adapter. Delivered on time from the Netherlands to Ireland, very well packaged with no handling damage.
