I don’t see anything obvious.

Try adding hdmi_force_hotplug=1 to the config.txt file
sudo nano /boot/config.txt

This may help

We are complete newbies to this where would I add this??? I really need a step by step of the computer side of it.

Try adding hdmi_force_hotplug=1 to the config.txt file
sudo nano /boot/config.txt

If you plug the SD Card into a PC, ignore the “must be formatted prompt” close that with the X. There will be a config.txt file on the fat32 Boot partition. You can edit that with a text editor and just add the hdmi_force_hotplug=1 line to the end of the file and save it.
On the Pi, you open a terminal window and run
sudo nano /boot/config.txt
then look for and change
#hdmi_force_hotplug=1
to
hdmi_force_hotplug=1
or scroll to the bottom and add the
hdmi_force_hotplug=1
Press ctrl and x, then answer y and hit enter to save the edit.

Any line in the config.txt file with a # at the beginning is treated as a comment and ignored. remove the # and that line is acted apone on boot up. The config.txt file is kind of like a PC’s BIOS setup. Sort of kind of.

Thank you for the reply we will give it a go tomorrow and let you know how we get off. Thanks once again.
