The LG A1 OLED TV typically comes at an upper midrange price and offers great overall picture quality, particularly for movies and series, thanks to its perfect black levels and wide viewing angles. It's an excellent choice for dark room viewing but isn't as bright for well-lit environments. The TCL R648 LCD TV, at a premium price, has a higher gaming score and better brightness for bright rooms but has a narrower viewing angle and may not deliver the same perfect blacks as the OLED. It also comes with additional features like better speakers and a more premium build. If gaming and watching in a bright room are priorities, consider the TCL R648; if you're more into movies and viewing in a dark room, the LG A1 may be more suitable for you. Give Feedback

The LG A1 (OLED) is very good for movies & TV, while the TCL R648 (LCD) is good.
The LG A1 OLED offers perfect contrast and excellent black uniformity which are crucial for a great movie-watching experience, especially in dark scenes, while its ample viewing angles ensure consistent picture quality across different seating positions. On the other hand, the TCL R648, with its high contrast and good local dimming, also provides a commendable cinematic experience, but the black uniformity and viewing angles are not as strong as the LG's, which may affect the picture quality when viewed from an angle or in very dark scenes.

The LG A1 (OLED) is very good for sports, while the TCL R648 (LCD) is only fair.
The LG A1 excels in watching sports due to its perfect black uniformity, wider viewing angles allowing clear visibility regardless of where you sit, and superior response time which minimizes motion blur. The TCL R648, on the other hand, performs less impressively in sports viewing as it suffers from more limited viewing angles and a lower motion processing ability, making it less ideal for fast-action scenes common in sports.

The TCL R648 (LCD) is very good for gaming, while the LG A1 (OLED) is good.
The LG A1 boasts an excellent response time which is vital for smooth motion in games, but its input lag is among the best, ensuring minimal delay between player input and on-screen action. Conversely, the TCL R648, while having a very good response time making it suitable for gaming, does not match the LG A1's minimal input lag which can offer a more responsive gaming experience.

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.
