Hi, when connecting the cable DVI-D - HDMI to boot into Windows -> "The current input timing is not supported by the monitor display. Please change your input timing to 2560x1440@60hz or any other monitor listed timing as per the monitor specifications.". Windows is loaded when it works. Not working only during loading is Windows. If you connect the cable miniHDMI - HDMI, all working and everything is displayed at startup. Because of this non-displayable Bios and DOS cable DVI-D - HDMI. It can be something to do with it?
Sorry for my English.
