The Sony X77L is generally less expensive, making it a budget-friendly choice, but it performs less well than the Sony X85K in most areas. If you have a tight budget and need a decent TV for various content, the X77L is a practical option. However, the X85K offers better picture quality, particularly in bright rooms and for watching sports, and it has superior performance for gaming. The X85K also supports HDR content more robustly, with Dolby Vision support, and has an additional HDMI port, which might be helpful if you have multiple devices to connect. If your budget allows, and you prioritize higher performance for a wide range of content including gaming, sports, and movies, and plan to use it in both bright and dark environments, the X85K is the superior choice.

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."
