    should I be able to get 60Hz refresh rate from my laptop's Radeon HD 7570M to an external 3840x2160 display over DisplayPort 1.2?


      I can run using 30Hz refresh rate over DisplayPort 1.2 to my new Philips 4K monitor, but the monitor says it works best at 60Hz.  But I can't seem to get that setting to work, or my older AMD card just doesn't support it.  Does anyone know if I should be able to run at 60Hz, and if so how do I get that from my graphics card?  (i.e. driver update?)

      Radeon HD 7570M

      not sure (FAL2SY2 A3245)?
