A:AnswerYes. I am currently using the Roku Ultra device on this particular TV model, and it operates flawlessly.
The Xfinity Streaming App is definitely included in the Samsung App Store on this TV model as well.
A:AnswerI have checked the settings on this TV, and there does not appear to be an ambient mode built into the Smart Tizen operating system although a screensaver feature does exist.
I installed a Roku Ultra device onto this TV, and that device DOES in fact possess an ambient screensaver mode that allows for your personal photo stream, or one of the various themed screensavers that also display brilliantly on this TV model.
A:AnswerI don't thing so. I see a coax/optical/usb/hdmi.
You can get wireless conversion kits though. But also most sound bars can be connected with HDMI/coax/optical.
