The LG UP8000 may be more suited for general use and offers a slightly better overall picture quality. It excels relatively in gaming and sports content, and performs decently in bright rooms. However, it won't perform as well in dark rooms due to its limited contrast and black uniformity. The Sony X77L, on the other hand, is superior for watching sports and has a higher quality sound that supports various formats, including voice commands for easier accessibility. Its picture quality in bright rooms is slightly better than the LG, but like the LG, it also falls short in dark room performance. Both TVs are similarly priced and have a 65-inch screen with LED IPS technology, ensuring wide viewing angles but only modest contrast levels. If better sound and sports viewing are priorities, the Sony might be the favored choice; for gaming and a marginally better overall picture, you may lean towards the LG. Give Feedback

The LG UP8000 (LCD) and Sony X77L (LCD) are both poor for movies & TV.
The LG UP8000 struggles with movies and cinematic content because it lacks local dimming, has only moderate contrast which leads to washed-out blacks, and while its color accuracy out of the box is good, its poor black uniformity can hurt dark scene performance. The Sony X77J also underperforms in movie viewing due to poor contrast and local dimming, which reduce the depth of blacks, though it boasts good color accuracy and slightly better black uniformity than the LG, yet still not enough to offset its fundamental contrast limitations.

The Sony X77L (LCD) and LG UP8000 (LCD) are both only fair for sports.
The LG UP8000 has a fair response time, which is critical for watching fast-paced sports without much ghosting or trailing, and it manages reflections decently, meaning glare should not be too distracting. However, the Sony X77L has a superior motion processing feature, which makes it better at displaying smooth action during sports, although both have just fair reflection handling which can impact viewing when there are lots of lights or windows in the room.

The Sony X77L (LCD) and LG UP8000 (LCD) are both poor for gaming.
The LG UP8000 has a fair response time but excellent input lag, which might be suitable for casual gaming but can still present motion blur with fast-paced games. Conversely, while the Sony X77L has very good input lag, it has poor response time, causing slow pixel transition that can lead to smearing, making it less ideal for fast gaming action.

Although they have very similar scores, PerfectRec considers Sony X77L (LCD) to be only fair for cartoons & animation, while the LG UP8000 (LCD) is poor.
The LG UP8000's poor performance when watching cartoons is due to its satisfactory colors out of the box and its poor color gamut, impacting the vividness and variety of colors. On the other hand, the Sony X77L fares better because, despite its poor color gamut which affects color range, it has very good colors out of the box, delivering better initial color accuracy and appeal for animated content.

The LG UP8000 (LCD) and Sony X77L (LCD) are both only fair for news, talk, & other TV.
The LG UP8000 delivers good upscaling for standard definition content, an advantage when watching regular TV programs, but its SDR brightness is just fair, which may not be ideal in bright rooms. The Sony X77L also offers very good upscaling with a slightly better SDR brightness, making it a better choice for well-lit environments, although its out-of-the-box colors are richer than the LG which could enhance the viewing experience right from the start.

Although they have very similar scores, PerfectRec considers Sony X77L (LCD) to be only fair for bright room, while the LG UP8000 (LCD) is poor.
The LG UP8000 struggles more with brightness and reflection handling compared to the Sony X77L, making it less suitable for bright rooms. Specifically, the UP8000 has lower SDR and HDR brightness scores and handles reflections less effectively, while the X77L has modestly better performance in these areas, along with slightly more vibrant colors, which contributes to its fair performance in bright environments.

Stratos Kampourogiannis | July 2021
"What we liked on this one was the very sharp 4K images it could display, its good up-scaling capabilities, nice viewing angles and extremely low input lag. Lastly the new webOS 6.0 is great even if it needs some time to get your bearings while the redesigned Magic Remote feels fresh even if functionality remains the same."

"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."
