If you're on a budget, the TCL S450F is the more affordable choice and offers a better input lag performance, making it suitable for casual gaming or use as a monitor. However, the S435 is stronger in contrast, which is beneficial for watching movies but may not justify the higher price, especially given its overall fair picture quality and poor performance in bright rooms. Neither TV excels in handling reflections or local dimming, and both have a limited viewing angle. If your viewing environment is bright or you tend to watch from different angles, you might not find either TV to be ideal. Both support HDR, but for the latest formats like Dolby Vision and HDR10+, only the S450F has compatibility. Keep in mind, the S435 has slightly better sound with Dolby Digital Plus, whereas the S450F includes voice commands for accessibility. Give Feedback

"The TCL 4-Series is so inexpensive and capable you might start to question why there are any multithousand-dollar TVs at all. The 4-Series setup is intuitive and easy. If you're just looking for an easy-to-use TV with decent picture, this is an excellent place to start."

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.
