The LG A2 (OLED) is excellent for movies & TV, while the TCL R646 (LCD) is good.
The LG A2's OLED panel offers perfect black uniformity and contrast, making it excellent for watching movies and cinematic TV, particularly in dark rooms where these aspects are crucial. In contrast, the TCL R646, though still good, has slightly lower contrast and less effective local dimming, which may not render blacks as purely in dark scenes but performs better in brightness, making it more versatile in varied lighting conditions.

The LG A2 (OLED) is very good for sports, while the TCL R646 (LCD) is only fair.
The LG A2 OLED TV excels in sports viewing due to its excellent response time and very good motion processing, allowing for crisp and smooth action, with wide viewing angles and effective reflections handling enhancing group viewing. On the other hand, the TCL R646 LCD, while offering very good reflections handling and response time, lags behind in motion processing and viewing angles, which may result in blurrier images during fast sports and color shifts when viewed from the side.

The TCL R646 (LCD) is very good for gaming, while the LG A2 (OLED) is good.
The LG A2 has an excellent response time common in OLED technology, which is great for gaming, but is limited by a refresh rate of 60Hz, which could be a drawback for fast-paced games that benefit from higher refresh rates. The TCL R646, while having a very good response time not as fast as the LG's OLED's, supports a higher refresh rate of 120Hz, making it more suitable for gaming that requires quick screen updates, such as competitive multiplayer games.

The LG A2 (OLED) is very good for news, talk, & other TV, while the TCL R646 (LCD) is good.
The LG A2 OLED TV is very good for watching news and TV programs as it displays deep blacks due to its perfect contrast and handles upscaling of lower-resolution content well. The TCL R646, while it has slightly less contrast, shines with brighter screens in SDR content and also has a commendable performance at upscaling, making it a solid choice for daytime viewing and upscaling of standard definition content.

The TCL R646 (LCD) is very good for bright room, while the LG A2 (OLED) is good.
The LG A2 OLED is good for bright rooms due to its very good handling of reflections and decent SDR brightness, but its HDR brightness is only fair, which may not overcome intense sunlight. On the other hand, the TCL R646 with its LCD panel offers excellent SDR brightness and very good HDR brightness, which together with very good reflection handling makes it better suited for very bright environments.

Al Griffin | August 2022
"Movie fans will find a lot here to love, and the A2 series’ low prices compared with other OLED TVs will keep their wallets happy. Images had the deep blacks and detailed shadows typical of the best 4K TVs, while colors looked both fully saturated and clean. Also, the A2’s out-of-box picture performance in Filmmaker mode was mostly accurate, requiring only slight adjustments to optimize brightness, color, and contrast."

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.
