I just picked up a decently used
LG 27" 27BK67U-B.
Looks identical to this model on Amazon, but my ports are arranged differently. It says resolution is 3840 x 2160.
The colors sure are more crisp and much brighter, compared to my old-ass Samsung that I have been using for years.
xrandr | grep connected and it outputs
eDP1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 340mm x 190mm
HDMI1 connected 1920x1080+1920+0 (normal left inverted right x axis y axis) 480mm x 270mm
How do I change display to 3840x2160?
EndeavourOS + bspwm on Thinkpad E590.
Enumerate the names of all your video outputs, and the possible resolutions for those currently connected to a monitor:
Choose the name of the output you wish to change the resolution of, and:
xrandr --output <OUTPUT> --mode 3840x2160
Note: If running from a text terminal, that is not running in gfx environment, you’ll have to add a
-d :0 parameter, i.e:
xrandr -d :0 -q
xrandr -d :0 --output <OUTPUT> --mode 3840x2160
I confirmed this is indeed a
2.0 HDMI cable. Was using an older one, but my roommate had an extra.
xrandr: cannot find mode 3840x2160
What’s the next step?!
do you use a DE like kde, gnome? system setting - display
I made sure this model laptop can output up to that resolution, and it looks like it can.
SO, now I am stumped
xrandr and arandr are both only showing max 1920x1080. And I verified that my HDMI cable is indeed a 2.0 so it should be able to handle it.
Even the laptop specs should handle it.
not fimilar with wm. sorry
The specs of your laptop are confusing:
On the one side it says it supports high res on HDMI (but only with 24 Hz):
but on the other side it says that the HDMI port is just 1.4b:
I suggest you try USB-c resp. DisplayPort.
