• The ROKU will cast whatever a device will send it, the output depends on the initial settings you set on the ROKU and TV/monitor. Also depends on what the TV/monitor supports.

  I would recommend:

  • 
    Roku - Premiere Streaming Media Player - Black

• It streams from the web not a device so kind of you can. It sets automatically for the tv best picture ratio and hd version. But you can change it in the settings. So no it's not actually content aware but it sets for best available based on multiple factors
