If you prioritize a better overall viewing experience for various content types such as movies, sports, and gaming, the Sony X90J is a superior option. It offers enhanced picture quality, better performance in both dark and bright rooms, and has a higher contrast ratio, which is beneficial for viewing in darker environments. For gaming, the X90J also has a higher gaming score and supports a higher refresh rate, making it more suitable for fast-paced action and reducing motion blur. However, if you are on a tighter budget and are looking for a TV that's easier on your wallet, the Sony X77L comes at a lower price point. It is capable of handling most content decently, but its performance in dark rooms and overall picture quality is not as impressive. Also, with fewer HDMI ports, it might limit the number of devices you can connect simultaneously. Both TVs lack HDR10+ support but do support Dolby Vision and HLG. The X77L has an IPS panel which usually provides wider viewing angles, making it a good choice for rooms where viewers are spread out. In contrast, the X90J has a VA panel with better contrast but narrower viewing angles. Neither of them has standout speakers or audio capabilities. In conclusion, choose the Sony X90J for a higher quality viewing experience across all types of content and a better gaming experience if budget is not the primary concern. Opt for the Sony X77L if cost savings are a critical factor and you're willing to compromise on picture quality and dark room performance. Give Feedback

The Sony X90J (LCD) is good for movies & TV, while the Sony X77L (LCD) is poor.
The Sony X77L's lower contrast, weaker local dimming, and poorer black uniformity compared to the Sony X90J, which has higher contrast, effective local dimming, and better black uniformity, make it less suitable for movies and cinematic TV where deep blacks and contrast are key. While both have good color accuracy, the X90J's better color volume and gray uniformity also contribute to a more immersive viewing experience.

The Sony X90J (LCD) is very good for gaming, while the Sony X77L (LCD) is poor.
The Sony X90J is better for gaming because it has a higher response time, ensuring smoother motion with less blur during fast-paced games, while the Sony X77L has a lower rating in this aspect, which can result in more motion blur. Additionally, the X90J has a lower input lag, providing a more responsive gaming experience, in contrast to the X77L, which, despite having a decent input lag, doesn’t match the performance of the X90J in this regard.

The Sony X90J (LCD) is very good for cartoons & animation, while the Sony X77L (LCD) is only fair.
The Sony X90J produces better colors out of the box along with a wider color gamut, which translates to more vibrant and accurate colors for cartoons and animation, while the Sony X77L, despite its fair performance, cannot match the color replication and richness due to its lower color gamut and volume performance. Additionally, the somewhat important factors like color volume and SDR brightness also favor the X90J, leading to a more immersive viewing experience in various lighting conditions compared to the X77L.

The Sony X90J (LCD) is very good for news, talk, & other TV, while the Sony X77L (LCD) is only fair.
The Sony X77L TV provides decent upscaling and SDR brightness which are very important for watching news and TV programs, but it struggles with color reproduction straight out of the box and has a limited color gamut affecting the vibrancy and accuracy of on-screen content. On the other hand, the Sony X90J excels in both upscaling and SDR brightness, ensuring clear and bright visuals, and it also offers better colors out of the box and a broader color gamut, resulting in more lifelike and varied shades which enhance the overall viewing experience for such content.

The Sony X90J (LCD) is good for bright room, while the Sony X77L (LCD) is only fair.
The Sony X90J is better suited for bright rooms than the Sony X77L, due to its higher brightness in both standard and high dynamic range content, meaning it can more effectively combat glare. Furthermore, the Sony X90J has better handling of reflections, which alongside its superior brightness, makes it a more favorable choice for well-lit environments.

Although they have very similar scores, PerfectRec considers Sony X90J (LCD) to be good for sports, while the Sony X77L (LCD) is only fair.
The Sony X90J is better for sports due to its superior motion processing and faster response time, which reduces trailing and blur in fast-moving scenes. While both TVs struggle with reflections, the X77L's better viewing angles make it more suited to wider seating arrangements, despite its lower performance in motion handling and slower response time.
