I would like to use an external 4K monitor with my Thinkpad X1 extreme laptop with Intel 630 graphics and a GeForce GTX 1050 Ti card. There is no display on the external monitor when connected, probably because the HDMI output runs off the Nvidia card (?).
I followed the link from the Wiki article (https://endeavouros.com/docs/hardware-and-network/nvidia-installer/) and the Nvidia site indicated the Version 441 driver. I messed up the previous installation of Endeavour OS after activating the Nvidia driver led to a black screen, and I could not recover even after uninstalling the proprietary driver and using the Nouveau driver. I would like to use both screens if possible, but atleast the 27" 4K monitor alone if necessary. I have been following the discussions on this forum and I saw some suggestions to run ‘sudo nvidia-installer -b’ and one to install the Nvidia driver and optimus. I only have nvidia-installer-dkms installed on my system. Should I install nvidia-installer separately? The relevant output from xrandr is
Screen 0: minimum 8 x 8, current 3840 x 2160, maximum 32767 x 32767
eDP1 connected primary 3840x2160+0+0 (normal left inverted right x axis y axis) 340mm x 190mm
3840x2160 60.00*+ 59.97
…
VIRTUAL1 disconnected (normal left inverted right x axis y axis)
eDP-1-2 disconnected (normal left inverted right x axis y axis)
HDMI-1-1 disconnected (normal left inverted right x axis y axis)
DP-1-1 disconnected (normal left inverted right x axis y axis)

Thanks.
