Hi Todd, it seems that your problem is basically the software. You mentioned that your better half is having a hard time dealing with the installed digital signage. I suggest you first contact the provider of the signage regarding the software, they should assign a technician to teach your better half how to use the software for the digital signage. However, if it turns out that they are of little help, you can go ahead and reach out to another provider, you can enquire if their software can be compatible with the already installed signages.
