How to cast this app?

How can I cast this app? I have a new Samsung 4k tv.

Hi @sith21176! At this time it is not possible to stream to your Smart TV using a built in Chromecast. Our team is aware of the desire from the community and we will notify you when we add new devices.

In the meantime you can check out the available devices list here: What devices is DC Universe available on? – DC Universe Help Center
