The Sony X90K offers a significantly better overall picture quality compared to the TCL S450G. It excels particularly in gaming performance, making it a great choice if you're an avid gamer. The X90K also provides better performance in both dark and bright rooms, meaning it will handle a variety of lighting conditions well. However, the Sony X90K is priced in the upper midrange, and it costs notably more than the TCL S450G, which is a budget-friendly option. If keeping costs down is a priority, the TCL S450G might be appealing, but it will offer a lower picture quality, particularly in darkroom settings, and won't perform as well for gaming. Both TVs support the same HDR formats and have similar sound quality, though the Sony has a slightly higher speaker power. If you prioritize a higher quality viewing experience and gaming performance, and are willing to invest more, the Sony X90K could be the better choice. If budget is a concern and you are willing to accept a compromise on picture and gaming performance, the TCL S450G might be the way to go. Give Feedback

The Sony X90K (LCD) is good for movies & TV, while the TCL S450G (LCD) is poor.
The Sony X90K excels at watching movies and cinematic TV due to its higher contrast, effective local dimming, and better black uniformity, ensuring deep blacks and minimal blooming, which enhances dark scene depiction. In contrast, the TCL S450G struggles with these aspects, offering lower contrast and poor local dimming, which results in less distinct black areas and could diminish the viewing experience in dark scenes.

The Sony X90K (LCD) is very good for cartoons & animation, while the TCL S450G (LCD) is poor.
The Sony X90K delivers better color performance for cartoons and animations due to its good color accuracy out of the box and gamut, which leads to livelier and more vivid scenes. In contrast, the TCL S450G falls short with only fair color accuracy and a poor color gamut, meaning it may not represent the rich and varied colors typically found in animated content as effectively.

"As Sony’s next-to-flagship LCD TV, the X90K series delivers impressive performance for the price. The XR90K had fairly accurate out-of-box color. The TV’s multi-position stand lets you either set the screen flush with any stand its mounted on or elevate it to clear space for a soundbar. With the latter option, you get around 3 inches of clearance enough to accommodate most soundbars. The X90K’s excellent suite of gaming features ranks it up there with the best 120 Hz 4K TVs."

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.
