I bought a Windows 8 laptop a few years ago. Watching it's videos that played while it was configuring windows for the first time, I learned that it had widi (wireless display). It's demo said I needed an adapter for the TV called Push to TV. I got it at Best Buy for about $75. It took many calls to India but after some firmware fixes it worked great. It's video is hi def and surround sound gets sent to my surround sound box. Windows 8.1 then screwed it up but Windows 10 made it better again. I just got a Windows 10 tablet and it mirrors it's display to my TV perfectly. Your laptop or tablet need the proper hardware for it to work and I understand that some Android tablets have the ability also.
