If Duplecast is not supported on Panasonic TVs, that means you won't be able to use the Duplecast IPTV app directly on your Panasonic television. In such cases, you might want to consider the alternative methods mentioned earlier to access Duplecast's content on your TV, such as using external streaming devices or casting from a compatible mobile device.
Additionally, it's a good idea to contact Duplecast's customer support or visit their official website for any updates or information about supported TV platforms. They may provide guidance or recommend specific devices that work well with their service.
