The Sony X80K typically costs a bit more than the Sony X77L, but it offers better performance for bright room viewing, sports, upscaling, and motion processing. It also supports Dolby Vision, which can provide a better HDR experience if you watch content that takes advantage of it. However, if you're watching in a darker room, you might not see a big difference between the two, as neither are particularly strong in dark room performance. For gaming, while both have low input lag, the X80K is a slightly better choice, with a small edge in responsiveness and slightly better picture quality. In terms of audio, neither TV boasts great speakers. If sound is a priority, consider investing in a standalone sound system. The Sony X77L has one less HDMI port than the X80K, so if you plan to connect multiple devices, that may be a consideration. Finally, if cost is a concern, the Sony X77L is less expensive and may be the better overall value for your needs, especially if your viewing environment and content choices don't demand the X80K's advantages.

The Sony X80K (LCD) is good for sports, while the Sony X77L (LCD) is only fair.
The Sony X80K outperforms the Sony X77L in sports viewing mainly because it has better motion processing which leads to smoother action, a critical aspect for fast-paced sports content. While both models may struggle with reflections and have similar viewing angles, the Sony X80K’s advantage in handling motion justifies its superior performance for sports fans.

The Sony X80K (LCD) is good for cartoons & animation, while the Sony X77L (LCD) is only fair.
The Sony X80K is better at displaying a range of colors for cartoons due to its good color gamut compared to the poor color gamut of the Sony X77L, which limits its color variety. Despite both having very good colors out of the box, which means minimal adjustment is required for an accurate picture, the better color gamut of the X80K makes it superior for vibrant animated content.

The Sony X80K (LCD) is good for news, talk, & other TV, while the Sony X77L (LCD) is only fair.
The Sony X80K outperforms the Sony X77L when watching news and TV programs due to its better upscaling of lower-resolution content and higher score in colors out of the box, which means that it delivers clearer images and more accurate colors even without adjustment. Additionally, the X80K has a higher contrast compared to the X77L, providing a better visual experience with deeper blacks and more noticeable differences between light and dark areas, which is beneficial for viewing detailed content like news and talk shows.

Although they have very similar scores, PerfectRec considers Sony X80K (LCD) to have only fair picture quality, while the Sony X77L (LCD) has poor picture quality.
The Sony X77L exhibits poor picture quality due to its lower scores in color gamut and color volume, impacting the range and depth of colors displayed, while the same TV's poor black uniformity affects the consistency of dark scenes, particularly noticeable when watching in dark rooms. In comparison, the Sony X80K shows fair picture quality, as it has a better color gamut, which allows it to produce a wider range of colors, and although it shares a similar poor black uniformity with the X77L, its overall combination of qualities such as HDR brightness and colors out of the box leads to a somewhat improved viewing experience.

The Sony X80K (LCD) and Sony X77L (LCD) are both poor for gaming.
The Sony X77L's poor gaming performance is due to a slow response time, which can result in motion blur, while the Sony X80K, although marginally better, still has a fair response time and input lag, neither ideal for fast-paced gaming or competitive play. Both TVs also have a standard refresh rate of 60Hz, which is less than ideal for a smooth gaming experience as modern games often benefit from higher refresh rates.

The Sony X80K (LCD) and Sony X77L (LCD) are both only fair for bright room.
The Sony X77L and Sony X80K both have fair performances in a bright room due to their similar limitations in handling reflections and delivering high brightness, which are very important for that setting; however, while their color volumes and color gamuts are somewhat important, they also only provide fair performances, which does not help differentiate them significantly in this context.

"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."

"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."
