If you're looking for superior picture quality, especially in dark rooms, and don't mind spending more, the LG C3 OLED is a clear choice with its excellent contrast and perfect blacks. However, if you're on a tighter budget and typically watch TV in a room with ambient light, the TCL R646 with its LCD display might serve you well. The TCL R646 also usually costs much less than the LG C3. Keep in mind that OLED TVs like the LG C3 can suffer from permanent burn-in when static images are displayed for long periods, which is a non-issue for LCD TVs like the TCL R646. Give Feedback

The LG C3 (OLED) is excellent for movies & TV, while the TCL R646 (LCD) is good.
The LG C3 OLED's perfect contrast and exceptional black uniformity provide deep blacks and high picture quality for movies and cinematic content, benefiting from OLED technology which ensures that local dimming is not necessary. On the other hand, the TCL R646, while still delivering good contrast and black uniformity with its miniLED backlight, falls short in local dimming performance compared to the LG C3, resulting in a less impressive movie-watching experience.

The LG C3 (OLED) is very good for sports, while the TCL R646 (LCD) is only fair.
The LG C3 OLED is favored for sports due to its superior response time and wider viewing angles, ensuring fast-moving scenes are clear and that the picture remains consistent from different seating positions. The TCL R646, while acceptable, has a slower response time and narrower viewing angles, making its sports-watching experience less optimal, especially for viewers sitting off to the side.

The LG C3 (OLED) is excellent for gaming, while the TCL R646 (LCD) is very good.
The LG C3 OLED is better suited for gaming due to its top-tier response time and input lag, meaning that it reacts to gaming actions almost instantly and maintains fluid motion, making it excellent for fast-paced gaming. On the other hand, while still very good for gaming, the TCL R646 LCD has slightly slower response time and input lag, resulting in a smallest delay during game play, but it remains a strong choice for gamers looking for a balance between performance and cost.

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.
