The HP Pavilion Notebook 15-AU113TX comes with Windows 10 which has wireless display Miracast technology built in allowing you to wirelessly display its screen to a supported TV like the Samsung K4300 Joy Smart TV.
To start Miracast from the HP Pavilion Notebook 15-AU113TX, first go to Settings -> Display in Windows and select 'Connect to a wireless display'.
Select the Samsung K4300 Joy Smart TV that shows up on the right side of Windows as 'Samsung 4 Series (32)'. The wireless display connection process will then start.
