Github Issues Dashboard on Phillips Smart TV

So far we have used JIRA and Atlassian had a wallboard function to show all issues on the TV. GitHub does not have this feature and the browser on the Smart Tv is not supported. I have to solve this problem. I already tried Geckoboard but they have a problem with private repositories. We all have private repositories.

It is a Phillips Smart TV 2017 (No Android)

My biggest problem is, when I want to open the Github Dashboard, the issues are not loaded on the Smart TV Browser.

Does anyone have a hint for me how I can solve it?
