==Step 1: Edit fb1 to fb0 in all these files:==
nano /etc/systemd/system/zynthian.service
nano /zynthian/zynthian-sys/sbin/splash-screen.sh
nano /zynthian/zynthian-sys/sbin/zynthian.sh
nano /zynthian/zynthian-ui/zynthian.sh
nano /zynthian/zynthian-ui/zynthian_gui_config.py
==Step 2: Edit boot/config.txt==
nano /boot/config.txt
Edit the following lines according to your screen or set to None and it will auto detect. Try None first if that does not work then put in screen width and height.
framebuffer_width=1024
framebuffer_height=600
comment out both lines
#dtoverlay=pitft28-capacitive,rotate=90,speed=32000000,fps=20
#dtoverlay=pitft28-resistive,rotate=90,speed=32000000,fps=20
If you are running the HDMI screen from the USB port add this line to the end of the file. changes the output voltage on all 4 usb combined from 600mA to double that, 1200mA. which is need for external hd or powering hdmi monitors. Note use a 2A power supply or greater.
max_usb_current=1
Add those lines at the end of the file suggested by the manufacture if None or framebuffer settings from above did not work. For example: 7" Waveshare display - the values below should be adjusted according to your screen
hdmi_goup=2
hdmi_mode=1
hdmi_mode=87
hdmi_cvt 1024 600 60 6 0 0 0
