If you prioritize overall picture quality, especially for movies and dark room viewing, the LG A1 OLED TV may suit you better, despite its higher price. However, in bright rooms, its performance is not as strong. The TCL S455 LCD TV is more budget-friendly and has a good picture quality for the price, although it may fall behind in terms of contrast and black uniformity compared to the OLED. For mixed usage like watching news or animation, both are adequate but the LG A1 generally outperforms the TCL S455. Give Feedback

The LG A1 (OLED) is very good for movies & TV, while the TCL S455 (LCD) is only fair.
The LG A1 excels in watching movies and cinematic TV thanks to its perfect contrast, efficient local dimming, and superb black uniformity, essential for a true cinematic experience, and benefits from good color accuracy and viewing angles which enhances the overall picture quality. In contrast, the TCL S455, while decent, falls short in delivering the same level of performance due to its lower contrast, significantly less effective local dimming, and weaker black uniformity, with colors and viewing angles that are not as impressive, reducing its overall appeal for movie watchers and cinephiles.

The LG A1 (OLED) is very good for sports, while the TCL S455 (LCD) is only fair.
The LG A1 is strong in handling reflections and has a wide viewing angle, making it suitable for watching sports in rooms with multiple seating areas and ambient light. In contrast, the TCL S455, while good for direct viewers, falls short in motion processing and has a narrower viewing angle, less ideal for sports-watching groups or brightly-lit rooms.

The LG A1 (OLED) is good for gaming, while the TCL S455 (LCD) is poor.
The LG A1 has excellent response time, which is crucial for gaming as it ensures fast on-screen action appears smoothly, and it features the best input lag performance, meaning there is minimal delay between a player’s actions and what is seen on screen. In contrast, the TCL S455, while offering the best input lag performance as well, has fair motion processing, which indicates less smooth transitions during quick movements in games.

GRAY UNIFORMITY

The LG A1 (OLED) is very good for cartoons & animation, while the TCL S455 (LCD) is only fair.
The LG A1 excels in displaying cartoons and animation due to its superior color accuracy out of the box and a wider color gamut, which means it can show a broader range of colors more accurately. Conversely, the TCL S455 has fair performance in these areas, unable to match the LG A1's color fidelity, making it less ideal for content that relies heavily on vibrant and varied colors.

The LG A1 (OLED) is very good for news, talk, & other TV, while the TCL S455 (LCD) is only fair.
The LG A1 excels in upscaling lower-resolution content such as standard news and talk shows to its native resolution, providing an improved viewing experience with good SDR brightness and color performance straight out of the box. On the other hand, while the TCL S455 is capable of upscaling content, its performance is more modest, and its lower SDR brightness and less accurate colors might not deliver the same clarity and vibrance in these TV programs as the LG A1.

The LG A1 (OLED) and TCL S455 (LCD) are both only fair for bright room, though the LG A1 (OLED) is somewhat better.
The LG A1 has impressive reflection handling and high contrast which benefits bright room viewing, yet its SDR and HDR brightness are only modest, meaning it may not overpower very bright room conditions. In comparison, the TCL S455 struggles more with reflections and has lower contrast, but similarly to the LG A1, it offers modest SDR brightness and even poorer HDR brightness, making neither TV ideal for very brightly lit spaces.

"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."

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.
