Tom's guide

Matthew Murray | February 2023
"The Sony Bravia X80K is an inexpensive LCD TV that turns out pleasing visuals and is armed with a number of other desirable features. Sony’s robust internal processing, results in generally better picture quality than you’ll usually get for this price. In practice, the X80K is satisfying to watch. You’re not going to get as sumptuous a picture as you may with other TVs from Sony or other companies, but we didn’t encounter anything that looked bad on it."
