Hi,
I'm trying to get xorg to display 4k. The context is:
FreeBSD 12.0-ALPHA8 r339084 amd64
ports r481640
AMD RX580 GPU
Asus X99 Extreme3 mobo
cpu: intel e5-2699v4
48GB RAM
Samsung UE48JU6410U monitor connected via HDMI
drm-next-kmod-4.11.g20180822
libdrm-2.4.93,1
xf86-video-amdgpu-18.1.0
xf86-video-ati-18.1.0,1
xf86-video-openchrome-0.6.0_3
xf86-video-scfb-0.0.4_7
xf86-video-vesa-2.4.0_2
linux_base-c7-7.4.1708_6 and all its xorg/mesa libs
/var/log/Xorg.0.log has this:
[ 3470.966] (II) AMDGPU(0): Printing probed modes for output HDMI-A-0

but further along we have this:

and
[ 3474.211] (II) AMDGPU(0): Printing DDC gathered Modelines:

[ 3474.211] (II) AMDGPU(0): Modeline "1920x1080"x0.0 148.50 1920 2008
2052 2200 1080 1084 1089 1125 +hsync +vsync (67.5 kHz e)
[ 3474.211] (II) AMDGPU(0): Modeline "800x600"x0.0 40.00 800 840 968
1056 600 601 605 628 +hsync +vsync (37.9 kHz e)
so would this indicate the card is 4k capable but the HDMI port on the
card is not? Or the port on the monitor? Or something else?
thanks,
