      For using RX480, I followed ubuntu community,

      drivers - AMD rx 480 on 16.04 mesa - Ask Ubuntu

       

      ===================================================================================

       

      And now, I have some problem in syslog;

      Mar 10 12:34:50 kvmhost kernel: [  300.468145] [drm:drm_add_edid_modes.part.23 [drm]] *ERROR* Unknown HDMI VIC: 0

      Mar 10 12:34:51 kvmhost kernel: [  302.327907] [drm:drm_add_edid_modes.part.23 [drm]] *ERROR* Unknown HDMI VIC: 0

      Mar 10 12:34:52 kvmhost kernel: [  302.676160] [drm:drm_add_edid_modes.part.23 [drm]] *ERROR* Unknown HDMI VIC: 0

       

      sudo dmesg | grep drm

      [ 1502.463789] [drm:drm_add_edid_modes.part.23 [drm]] *ERROR* Unknown HDMI VIC: 0

      [ 1502.804936] [drm:drm_add_edid_modes.part.23 [drm]] *ERROR* Unknown HDMI VIC: 0

       

      Moreover, I can't use 4K 60Hz.

      The monitor can support 4K 60Hz, I checked it.

       

      Could you give me a hand for fix it?
