Same summary

The BenQ RD280UG monitor with a 71.6 cm diagonal and a 3:2 aspect ratio is particularly suitable for business users who often work with multiple windows or large documents, thanks to its extremely large working area. The high UHD resolution provides a very sharp image, which is an advantage when reading small text or doing graphic work. The monitor is also suitable for home users who are looking for a versatile display for work, browsing or occasional multimedia. For the most demanding games, where an exceptional refresh rate and a very low response time are key factors, this model is not the best choice, but it offers enough quality for casual gaming and office work.
