For a variety of reasons,  the  Smart TV  features  on my 43 inch LG
are a royal PITA  -  I've been using my laptop  and connecting to the
TV with a  Display Port=HDMI cable.   The TV also has  USB sockets  -
is there any  significant difference in quality  between  HDMI and USB
cables  when used  for this  ?   I'm considering buying a  longer
cable  HDMI=HDMI    for my wife to use with her new laptop.
 I did try a google search but got lost-in-the-weeds.
  Thanks   John T.
