my pc is hard wired through an HDMI cable, but I like the ability to let me pc do pc things and my tv to take care of the rest. the smart app is great when it works, but they made some negative changes and they need to be addressed. I'm not the only one having problems. I've been in touch with the help desk and gave them a solution. have to see if their tech nerds are smart enough to understand what a told them to do. a buffer clear is quite easy actually.
