@ian57 so I just make the code adjustments on the config.txt file by adding this line of code correct?
uncomment if hdmi display is not detected and composite is being output
hdmi_force_hotplug=1
uncomment to force a specific HDMI mode (here we are forcing 800x480!)
hdmi_group=2
hdmi_mode=1
hdmi_mode=87
hdmi_cvt=800 480 60 6 0 0 0
max_usb_current=1
