Hi all,

 

I have recently got myself a Sapphire R9 Fury and a LG 27MU67 4K monitor which supports AMD Freesync as well as 3840*2160 at 60Hz.

But for some reason I am unable to get 60Hz out of this setup for any resolution above 1920*1080.

I am getting "DisplayPort lower setting applied" warning, and I can only choose 3840*2160 at 30Hz.

The monitor is connected with the card with a Display port cable.

 

After all these methods I tried, the problem still exist:

  1. Delete driver/Re-install driver/configure with only one monitor plugged in (as I have a second HDMI monitor)
  2. Replace a new display port cable (tried 3 different cables)
  3. Update to the latest driver
  4. Restore to factory setting and re-install driver
  5. Unplug the card and put it back in
  6. Update monitor’s driver / turn on Display port 1.2 setting

 

I don't think it is the monitor's problem nor the cable's, because I was able to get 3840*2160 60Hz with my old Asus GeForce GTX670.

 

Please help, thanks!
