great monitor. upgrade from U2410 i had before. connected with display port cable to 2012 MBP. the problem, when i turn the display off, the mac won't recognize that: - still runs on the faster GPU instead of Intel integrated - applications that i use on the display won't move automatically to laptop screen - laptop it behaves as if the display is still on sucks. anyone experiencing the same ? any workaround ? except pulling the display cable out ?
