If you want a TV that's slightly better for viewing in bright rooms, the Samsung AU8000 is a better choice. However, the Sony X77L offers slightly better performance for sports content and has voice command features for accessibility. The Samsung model may be slightly more expensive than the Sony, but it also has slightly better performance for general content, including movies and gaming. Both TVs are similar in their offerings for smart features, such as HDR support, although the Samsung does not support Dolby Vision while Sony does. Give Feedback

USA Today

Michael Desjardin | April 2023
"To put it directly: you’d never see a mid-range 4K TV hitting this black levels half a decade ago. AU8000 plays the part of a higher-end TV thanks to its sleek design. If you’re upgrading to a smart TV for the first time, the software is a great way to dip your toes in the streaming water."

Milton Clark | September 2023
"For an entry-level model, Sony’s X77L is a decent 4K TV. It’s color reproduction, along with crisp and clean picture images revealed plenty of detail and clarity thanks in part to Sony’s excellent video processing."
