Output information to multiple remote displays with the ability to edit?

Question

System administration

Greetings colleagues!
Maybe one of you has already implemented something similar, ready to learn from the experience.

Task:
Display different information on 3 information displays (TV - installed in different places) with the possibility of editing from several workplaces.
The task is to give employees information about what to do, in the morning 1 person enters the information - a senior mechanic, he distributes work among employees, then when the employee does the work, acceptance - Quality Control Department (second workplace for editing data) must change the status of the task so that the person can proceed to the next one.

Implementation options:
What I could think of so far - TV with thin clients, a remote connection to the TV channel through a session server, filling in information (for example, excel or Google spreadsheets).
What is not convenient:
1) Serial connection to the session of each TC and input of information.
2) Start up on the server and give access rights to sessions to people who are not competent in this.
3) If you remove the connection to the session, and give an RDP connection, in order to return the information output to the TV, you will need to relogin to the system with the shopping mall.

I really ask for your help.

Answer 1

Use web technologies. Let TK open a fixed URL, which contains up-to-date information. If the TV has a browser, then you can do without TC, I guess.
It remains to write the interface so that the senior mechanic is comfortable and understandable. Or take a ready-made solution and let him get used to what is. Maybe even Wordpress. Maybe a more specific solution could be suggested. But I am sure that it is the web that is optimal in this task. No RDP, etc.
In fact, bike something like a simplified service desk on the web. You can freelance.

driving information (for example excel or google spreadsheets).

If Google tables suit you, then you don’t even have to reinvent the wheel, just open the table with a browser. You can force a page refresh in the browser with an extension, for example https://chrome.google.com/webstore/detail/easy-aut...
