Hello all,
I currently have a Raspberry Pi 4 connected to a waveshare 5.5 inch AMOLED display with the resolution 1080x1920. The display is not getting any output. I have the display touch plugin installed, and have tried turning it on and off repeatedly to no avail.
The following are the results of the command “cat /boot/userconfig.txt”
# Add your custom config.txt options to this file, which will be preserved during updates#
max_framebuffer_height=1920
config_hdmi_boost=10
hdmi_group=2
hdmi_force_hotplug=1
hdmi_mode=87
hdmi_timings=1080 1 26 4 50 1920 1 8 2 6 0 0 0 60 0 135580000 3
The following are the results of the command “sudo tvservice -m DMT”
Group DMT has 4 modes:
mode 4: 640x480 @ 60Hz 4:3, clock:25MHz progressive
mode 86: 1366x768 @ 60Hz 16:9, clock:72MHz progressive
(prefer) mode 87: 1080x1920 @ 60Hz 16:9, clock:135MHz progressive
mode 88: 1080x1920 @ 60Hz 16:9, clock:135MHz progressive
