Purchased new in 2017 and used at home for about 2-3 hours on weekends. Operation has been confirmed on both Mac and Windows 11. I used it for document work and photo viewing, and I didn't notice any problems with those uses. I am not a monitor expert, so I haven't inspected for minor details like dead pixels, but please understand. It has a built-in USB hub, and you can use multiple devices connected to the monitor by connecting only one USB cable. I connected a keyboard, mouse, and camera. The included accessories are the power cable, DP cable, USB hub cable, and HDMI cable, as shown in the 11th photo. There are minor scratches from installation. Please check the photos. To prevent damage, I will remove the stand for shipping and pack it separately.
