If you prefer a TV that is generally better for gaming and sports content, the Sony X77L would be a good choice. However, it tends to be more expensive and might not perform as well in dark rooms. On the other hand, the TCL S450G is a more budget-friendly option with decent overall picture quality and is also slightly better for viewing in dark rooms. But, be aware that it may not handle reflections as well and could have a narrower viewing angle, which means the picture quality might degrade when viewing from the side. Give Feedback

The Sony X77L (LCD) and TCL S450G (LCD) are both only fair for sports, though the Sony X77L (LCD) is somewhat better.
The Sony X77L offers better motion processing compared to the TCL S450G, leading to smoother playback during fast sports action, but its reflections handling is not as strong, which could be problematic in a bright room. Both TVs show fair performance in gray uniformity, but the TCL S450G has a better response time, meaning it displays fast-moving sports with less blur; however, its narrow viewing angles could limit the view for groups spread around the room.

The TCL S450G (LCD) and Sony X77L (LCD) are both poor for movies & TV.
The Sony X77L suffers in movie and cinematic TV watching due to its low contrast, poor local dimming, and subpar black uniformity, all crucial for deep blacks in dark scenes. The TCL S450G also performs poorly for the same content, with insufficient contrast for a punchy image, ineffective local dimming, and inadequate black uniformity to prevent gray-looking dark scenes.

The Sony X77L (LCD) and TCL S450G (LCD) are both poor for gaming.
The Sony X77L and TCL S450G both have poor ratings for response time, indicating they might not handle fast-moving images well, which is a drawback for gaming. While the TCL S450G has the lowest input lag, making it more responsive to gaming inputs, both still fall short in performance for demanding gaming situations.

Although they have very similar scores, PerfectRec considers Sony X77L (LCD) to be only fair for cartoons & animation, while the TCL S450G (LCD) is poor.
The Sony X77L is considered fair for watching cartoons and animation because it displays colors very accurately right out of the box, despite having a poorer color gamut which could hamper the range of colors shown. On the other hand, the TCL S450G is rated poor in this area due to merely fair accuracy in colors out of the box and similarly limited color gamut, affecting the vibrancy and variety of colors necessary for animated content.

Although they have very similar scores, PerfectRec considers Sony X77L (LCD) to be only fair for news, talk, & other TV, while the TCL S450G (LCD) is poor.
The Sony X77L provides better upscaling and SDR brightness than the TCL S450G, which makes it more suitable for watching news and TV programs as it can better handle lower-resolution content and has higher brightness for day-time viewing. While colors out of the box and the color gamut are similar for both TVs, the Sony has an advantage with its upscaling and brightness, contributing to clearer and more vibrant images in a variety of viewing conditions.

Although they have very similar scores, PerfectRec considers Sony X77L (LCD) to be only fair for bright room, while the TCL S450G (LCD) is poor.
The Sony X77L provides a better experience in a bright room compared to the TCL S450G because it has higher SDR brightness, which helps maintain picture quality even in well-lit environments. Additionally, while both TVs have fair reflection handling, which means they may struggle with direct reflections, the Sony's superior brightness can help offset this drawback to some extent. Contrast, color volume, and color gamut do impact picture quality but are less critical than brightness and reflection handling in bright room conditions.

"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."

About Sony
Sony stands as a highly experienced and widely trusted TV manufacturer, earning a reputation that surpasses all others. A Japanese company, Sony has been making TVs for far longs than it has been making Playstation game consoles. Sony's high-end TVs are often regarded as the ultimate choice for videophiles, representing the epitome of quality, albeit at a premium price point. Renowned for their advanced and precise motion handling, as well as their cutting-edge local dimming algorithms, Sony consistently delivers unparalleled performance in these areas. They include Google TV software with all their TV sets, which grants access to the largest selection of apps available and they also include Bravia Core which is a movie streaming platform specifically for Sony TVs that offers higher picture quality by using more bandwidth.
About TCL
TCL, the highly recognizable TV brand from China, has firmly established itself as the second-largest manufacturer in terms of sales volume. Renowned for striking an impressive balance between affordability, picture quality, and design, TCL TVs deliver a compelling overall package. While they have traditionally excelled in the low-end and midrange TV segments, TCL has recently made remarkable strides in the realm of high-end televisions, introducing impressive models that rival top competitors. Most TCL TVs use Roku software which is very user friendly and easy to use, but they have a few other models that use Google TV which has the largest app selection, but is not as user friendly as Roku.
