    low refresh rate Radeon E8870MXM


      I'm using AMD Radeon E8870MXM. Does this card support 60 hertz @ 4K resolution?
      When I set the screen resolution to 3840 x 2160, the screen refresh rate is stuck at 30 hertz. It can go up to 60 hertz at 1080p.

      But the monitor I'm using says it's optimized for 3840 x 2160 @ 60 hertz, so I think this must be an issue with the AMD graphics card?
