The monitor itself appears to work fine. There is only a simple sheets of instructions and a CD with a very basic manual. No drivers, no set-up during installation, Windows 8.1 doesn't recognise the model and thinks it is a simple PnP monitor. I queried this with Asus support - the website provides nothing other than a download of the useless manual - and it took many emails before they even understood the problem. They were unable to help, but did at least tell me where to send a formal complaint. Last time I ever buy Asus.
