Could not get 60Hz on 4K display

I have a Sapphire R9 290, had it for a while, worked fine. Recently I purchased a new philips bdm4065uc monitor and for the life of me I could not get it to display 60Hz, only 24Hz and 30Hz options are available to me. A quick troubleshoot:

- I have turned monitor setting to DP 1.2

- tried replugging the Graphics card and cables multiple times.

- tried to reinstall AMD drivers (currently on 16.6.1). I know the monitor works because when I uninstall all the AMD drivers, it can display native 4k@64Hz perfectly. Once drivers are installed, the options for higher refresh rate are gone.

- tried to patch pixel limit

- tried custom resolution, after setting it to 60Hz the system become super laggy


I believe this is a pretty wide spread issue, however I could not find any official recognition from AMD that it even exists. Please let me know if I'm missing something.
