Somehow while watching Sling, I leaned onto my roku remote and then all of a sudden I get a small screen to the right of the TV showing the current show and the guide was now the background. I never seen this option and I don't know how to make this happen again. Any help please and thank you.
Sorry I finally figured it out. I have a Onn Roku TV and holding the up arrow button for 5 seconds gave me the option to see the live Sling TV show at the bottom right corner while scrolling through the main channel guide in the background. I love this little feature, sorry again and hope this help anyone else.
