Choose the LG QNED90 if you prefer better performance for gaming, a brighter screen for viewing in well-lit rooms, improved contrast in dark settings, and better color fidelity. It's more costly but offers a superior viewing experience for varied content, especially in diverse lighting conditions and for gamers who value low response times. Opt for the TCL S450G if you're looking for a more affordable option that still delivers satisfactory performance for mixed usage. While it won't match the LG in performance or features, it's a solid choice for casual watching and can suffice in both bright and dark rooms, albeit with some compromises in picture quality and motion handling.

The LG QNED90 (LCD) is only fair for movies & TV, while the TCL S450G (LCD) is poor.
The LG QNED90 provides a better experience for movies and cinematic TV due to its local dimming and black uniformity features which enhance contrast significantly, offering deeper blacks and minimizing blooming.

The LG QNED90 (LCD) and TCL S450G (LCD) are both only fair for sports, though the LG QNED90 (LCD) is somewhat better.
The LG QNED90 has good response time and motion processing, which are very important for sports, but fair reflection handling and a relatively wide viewing angle make it a decent choice for watching sports in various conditions. The TCL S450G has the best response time which is great for sports, but its motion processing and reflection handling are poor, and it has a narrow viewing angle, making it less versatile for group sports viewing or bright rooms.

The LG QNED90 (LCD) is very good for gaming, while the TCL S450G (LCD) is poor.
The LG QNED90's gaming performance is superior due to its very good response time and input lag, meaning the screen updates quickly and there's minimal delay between controller input and action on-screen. In contrast, the TCL S450G, while offering the best input lag, falls behind due to its poor response time, resulting in less fluid motion in fast-paced games.

The LG QNED90 (LCD) is good for cartoons & animation, while the TCL S450G (LCD) is poor.
The LG QNED90 is better for watching cartoons and animation because it has good colors out of the box and color gamut, which are very important for animated content.

The LG QNED90 (LCD) is very good for news, talk, & other TV, while the TCL S450G (LCD) is poor.
The LG QNED90 is well-suited for news and talk shows due to its very good SDR brightness and proficient upscaling, which ensures clear images even from lower resolution content. In contrast, the TCL S450G performs poorly with such content because its SDR brightness is low and upscaling capabilities are less effective, which may lead to less clear and less vibrant image quality.

"When it comes to HDR brightness it has very bright highlights and impressive HDR. In terms of design the QNED90 looks beautiful.

About LG
LG, a prominent TV brand from Korea, has played a significant role in popularizing OLED TVs. OLED technology is hailed as the future of TV technology. 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
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.
