If you're looking for superior picture quality in dark rooms and enjoy movies or cinematic content, the LG A1 OLED TV may be the better choice, offering excellent contrast and black uniformity. However, it's not as bright as the TCL R646, so it may not perform as well in sunny rooms. On the other hand, if gaming is a priority for you, the TCL R646 offers better gaming performance and a higher refresh rate, which is great for fast-paced action. It's also a bit brighter than the LG, making it suitable for well-lit environments. Both TVs are in the upper midrange price bracket, with the LG A1 being slightly more expensive. Keep in mind that OLED screens like on the LG can be prone to burn-in with static images over time, whereas the TCL's LCD panel doesn't have this risk. Give Feedback

The LG A1 (OLED) is very good for movies & TV, while the TCL R646 (LCD) is good.
The LG A1 OLED's perfect contrast and black uniformity make it ideal for watching movies and cinematic content, providing deep blacks and a wide viewing angle, though its colors might need slight adjustments. The TCL R646 LCD, while also good for movies, has lower contrast and black uniformity but compensates with a brighter screen and decent local dimming, which might make it more suitable for well-lit rooms.

The LG A1 (OLED) is very good for sports, while the TCL R646 (LCD) is only fair.
The LG A1 is better for watching sports due to its OLED panel which provides excellent response time and motion processing, ensuring smooth action without blur, along with wide viewing angles that maintain picture quality when viewed from the side. The TCL R646, while good, has a lower performance in motion processing and narrower viewing angles, which can be noticeable during fast-paced sports but handles reflections just as well as the LG A1.

The TCL R646 (LCD) is very good for gaming, while the LG A1 (OLED) is good.
The LG A1 has an excellent response time, which is crucial for gaming as it determines how quickly the display can change pixels from one color to another, reducing motion blur. However, the TCL R646 offers a very good response time as well as a higher refresh rate, which makes for a smoother gaming experience, especially in fast-paced games, and it also has good input lag, ensuring minimal delay between a user's actions and what's seen on the screen.

The LG A1 has fair SDR and HDR brightness and very good handling of reflections, making it suitable for somewhat bright rooms but not the best in very bright environments. In contrast, the TCL R646 offers excellent SDR and very good HDR brightness, along with very good reflection handling, thus it performs better in bright conditions; both TVs have good color volume and very good color gamut, which contribute to vibrant image quality regardless of lighting condition.

In contrast, the TCL R646 LCD also offers good out-of-the-box colors and a good color gamut but may not deliver as broad a spectrum of colors or as accurate color reproduction as the OLED.

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.
