Hi Daniel,
I hope you are well.
While searching for a new monitor I wanted to buy a miniHDMI->HDMI adapter or cable to connect it.
My Samsung laptop has a Intel HD graphics 3000 GPU and a miniHDMI connector.
Unfortunately, I have no idea how to get information about supported HDMI versions and or supported resolutions when there is *no* external monitor connected.
root# xrandr --listmonitors Monitors: 1 0: +XWAYLAND0 1366/293x768/165+0+0 XWAYLAND0
root# egrep -i 'hdmi|snb' /var/log/Xorg.0.log 101:[ 81.251] (II) modeset(0): glamor X acceleration enabled on Mesa DRI Intel(R) HD Graphics 3000 (SNB GT2) 105:[ 81.255] (II) modeset(0): Output HDMI-1 has no monitor section 176:[ 81.264] (II) modeset(0): EDID for output HDMI-1 180:[ 81.264] (II) modeset(0): Output HDMI-1 disconnected 337:[ 87.548] (II) config/udev: Adding input device HDA Intel PCH HDMI/DP,pcm=3 (/dev/input/event11)
I am here on Linux v5.15.10 and using KDE/Wayland 5.23.4.
Do you need further information?
Thanks in advance.
