I got a portable ASUS monitor. I didn't use it for a month. When I finally went to use it to find it didn't work. I packaged it up and sent it ASUS for a warranty repair. I get a notice back that there is a scratch on the screen so the warranty is void. They didn't even examine why the monitor wouldn't turn on. They send a picture of the scratch and said too bad. By the way, we will fix it for you but it will cost you more than going out an buying another one. Runaway from ASUS products. You learn about a company when things go bad. ASUS is a terrible company.
