If you prioritize top-notch picture quality, especially for movies and gaming, and are willing to invest more, the Sony A90K is a superior choice with excellent overall picture, contrast, and dark room performance, but it might not be as bright in well-lit rooms. On the other hand, the Sony X77L is more budget-friendly and offers good performance for general content like news and sports, with better brightness for sunny rooms, but it sacrifices picture quality, especially in dark rooms and for vibrant colors. Both models are good for using as a monitor, but keep in mind that the A90K has higher quality motion processing and sound, whereas the X77L may require an external soundbar for a better audio experience.
