In case the main intention is to have two screens (like for example, Laptop and TV screens showing different browser tabs), then the HDMI/wireless route might be better. The reason being even if the Kite app for smart TV is made available in the future, to use it, we will require a separate wireless keyboard/mouse for using it and a separate keyboard/mouse (in-built or wireless) for using the laptop. Switching between keyboard/mouse to use the two different screens might not be very convenient (A possible solution could be Logitech Flow or some kind of KVM Switch that works with Smart TV’s OS).
Also, in case you are interested, there was some discussion related to this topic on this thread.
