If you're looking for a higher performance TV and are willing to spend more, the LG QNED90 is the better choice. It offers better picture quality, gaming performance, sports viewing, and performance in bright rooms. Additionally, it supports a wider range of HDR formats including Dolby Vision and is better suited for dark room viewing.
On the other hand, if your budget is limited and you're looking for a TV that offers decent overall performance at a lower cost, the TCL S455 could be the preferred option. It has lower picture quality and gaming performance compared to the LG but is still a viable option for general viewing in various lighting conditions and is exceptional for enjoying dark, uniform scenes because of its impressive black uniformity. Both TVs have similar sound quality and a 65-inch screen size. Give Feedback

The LG QNED90 (LCD) is very good for news, talk, & other TV, while the TCL S455 (LCD) is only fair.
The LG QNED90 delivers a better experience when watching news, talk shows, and other TV programs because it has very good SDR brightness and upscaling, ensuring that lower resolution content is displayed clearly and visibly in most room settings. On the other hand, the TCL S455, despite being fair in upscaling, has only fair SDR brightness and poor color gamut, making it less ideal for vibrant and consistent color display in bright rooms, which could affect the viewing experience of such content.

The LG QNED90 (LCD) is good for bright room, while the TCL S455 (LCD) is only fair.
The LG QNED90 is better suited for bright rooms because it has 'very good' SDR and HDR brightness, which helps maintain picture quality in well-lit environments, paired with 'fair' reflection handling that can minimize the impact of lights on the screen. In contrast, the TCL S455, with its 'fair' SDR brightness and 'fair' reflection handling, may struggle to overcome ambient light, and its 'poor' HDR brightness means it won't shine as brightly when viewing HDR content.

"When it comes to HDR brightness it has very bright highlights and impressive HDR. In terms of design the QNED90 looks beautiful. The TV did great with fast response times, excellent reactions and instant rendering of all our commands. If you look for a good performing premium 4K TV the QNED90 ticks all the boxes."
"A highly affordable but reliably kitted-out 4K Roku TV that, while far from perfect, still punches above its price and delivers a great user experience. If you want to soup up movie night for a bargain, the 4-Series won’t let you down. You may never need to plug in a set-top box or streaming device."

Their TVs employ WebOS, a proprietary smart TV software that not only offers seamless functionality but also includes gaming-specific features, earning praise from players worldwide. Often regarded as the gateway to unparalleled viewing experiences, LG's mid-range OLEDs come highly recommended, making them a worthwhile investment for those willing to stretch their budget for superior quality.
About TCL

Renowned for striking an impressive balance between affordability, picture quality, and design, TCL TVs deliver a compelling overall package.
