A friend is buying a new TV: a 55 OLED 4K Smart TV.
Here is the thing: He has digital recordings of dozens of movies on his laptop Windows computer and would like to attach the computer to the TV to see the movies.
What must he do, or what must he buy, in regards to the new TV to make this happen? Does an HDMI connection give him a TV picture and sound or is there more to it than that? Is there something special he must look for in the TV? (He does NOT want to have to make DVD recordings.)
