ASUS The monitor has no defects. I used it for about 600 hours. The reason for selling is that I need the money to buy a smaller 27-inch monitor. The size of the monitor did not suit me because I play a lot of shooter and competitive games. And of course, I updated it to the latest update as shown in the picture MCM105. I ordered the monitor on March 1st. It's been with me for about two months. Brand: Asus
