I've never used HDMI before, so I might be doing
This is Dell Latitude 3340 laptop with 10.1-release.
I connected an hdmi monitor to it.
On boot everything is shown on the laptop
screen, nothing goes to hdmi monitor.
In dmesg I see:
dmesg | grep -i hdmi
pcm0: <Intel Haswell (HDMI/DP 8ch)> at nid 5 on hdaa0
pcm1: <Intel Haswell (HDMI/DP 8ch)> at nid 6 on hdaa0
pcm2: <Intel Haswell (HDMI/DP 8ch)> at nid 7 on hdaa0
Is that all that's expected? Or should there be more?
There is also a usb cable from the laptop to the
monitor. I think it's something to do with the sound.
At least I see in dmesg:
uaudio0: <DELL DELL UZ2315H, class 0/0, rev 2.00/13.08, addr 2> on usbus0
where UZ2315H is the monitor model.
pciconf -lv|grep -i hdmi
returns nothing. Is that expected?
The monitor simply says there's no
input signal coming.
