What reviewers say
Reviewers praise its detailed 4K image, vivid colour, strong contrast and quick response. They find the glare-reducing coating effective and the slim design well made. A powerful graphics card is needed to exploit 4K at 240Hz, while the lack of USB-C, speakers and other extras limits its versatility.
