The Sony X77L is less expensive and may suffice for basic TV watching and some gaming, but its performance is not as strong as the Sony X90L, notably in picture quality and motion handling, which is important for fast-paced content like sports or high-quality movies. The Sony X90L, while more expensive, offers better overall performance, higher picture quality, and advanced features like a higher refresh rate which is beneficial for gaming and watching action-packed scenes. If you have a well-lit room, the X90L also has better brightness to counteract glare. If budget is a primary concern and your viewing habits are not demanding, the X77L is a practical choice, but for a premium viewing experience especially in brighter rooms or for high-quality content and gaming, the X90L justifies its higher cost.

The Sony X90L (LCD) is excellent for news, talk, & other TV, while the Sony X77L (LCD) is only fair.
The Sony X90L is superior for watching news and talk shows due to its excellent SDR brightness and advanced local dimming technology, which contribute to clearer images and better contrast.

Although they have very similar scores, PerfectRec considers Sony X90L (LCD) to be good for sports, while the Sony X77L (LCD) is only fair.
The Sony X90L outperforms the Sony X77L when watching sports because it has superior motion processing, which is essential for smooth action and less blur in fast scenes, and it also has a better response time, leading to less motion blur overall. While the X77L manages reflections well, which is beneficial in bright rooms, and offers wide viewing angles, the X90L’s advantages in motion handling are notable for sports viewing despite it being less effective in reflections handling and having narrower viewing angles.
