The U.S. organization Consumer Reports has put several products from Samsung and LG on its list of the best super-sized TVs.
From LG, these include a 77-inch OLED model, which ranked second, and from Samsung, a 75-inch neo Q-LED model, which ranked fifth.
The reviews covered a total of 59 products from a number of brands.
Consumer Reports also recommended some of the South Korean tech giants' mid- and lower-end models.
As of the third quarter of last year, Samsung and LG had a market share in North America of over 65 percent for TVs at 70 inches and larger.
