Rotating Display Screen
-
@brendan_c23 pi doesnt know. pi4 has hdmi1, left port , and hdmi2, right port.
no relation to tv source
my tv has 4 ports
i have pi 0, pi 3, pi4, and jetson nano on tv sourcesall pis think they are using hardware port hdmi1
-
@sdetweil How can I rotate the display 90 degrees clockwise?
-
@brendan_c23 i think you were doing it correctly, but not using right hardware port
-
@sdetweil HDMI-2 is the only option that comes up in the Screen layout editor. I just checked and I have the hdmi cord plugged into the main micro hdmi port on the pi and HDMI 1 port on TV.
-
@brendan_c23 is this a pi4?
main is the one next to power supply
-
@sdetweil yes and yes its plugged in the main next to power supply
-
@brendan_c23 hm that worked for me last time i tried (couple of months)
-
