The LG QNED90 is an LCD TV that tends to be slightly more expensive. It has good overall picture quality, excels at gaming performance, and delivers decent results in bright rooms. It has reliable brightness for both SDR and HDR content, but its dark room performance is not the strongest due to lesser black uniformity. The LG QNED90 suits users who enjoy gaming and have varied viewing environments. The TCL R646 is also an LCD TV at a slightly lower price point. It too has impressive overall picture quality, with a slight edge over the LG for movie watching and cartoon content, and excellent performance in bright rooms. It has better contrast and black uniformity, making it superior for dark room viewing compared to the LG QNED90. This TV sacrifices some gaming features and has a narrow viewing angle. The TCL R646 is ideal for movie enthusiasts and those who prioritize picture quality in brighter settings. Give Feedback

The TCL R646 (LCD) is good for movies & TV, while the LG QNED90 (LCD) is only fair.
The TCL R646 (LCD) provides a better experience for movies and cinematic TV due to its outstanding contrast, effective local dimming, and excellent black uniformity, all of which are essential for dark room viewing. In contrast, the LG QNED90 (LCD) has fair contrast and good local dimming, but its black uniformity is just decent, meaning it might not perform as well in delivering true blacks in a darkened environment.

The LG QNED90 (LCD) is very good for news, talk, & other TV, while the TCL R646 (LCD) is good.
The LG QNED90 is very good for watching news and TV programs due to its high SDR brightness and impressive upscaling, which maintains clarity when enhancing lower-resolution content, while the TCL R646 is also good for these uses, as it combines very high contrast with excellent SDR brightness, but may not upscale lower-resolution content as effectively. Both TVs offer good colors out of the box and a wide color gamut which contribute to a vibrant viewing experience, and while they both have local dimming and decent contrast, the TCL R646 notably has a higher contrast, which can enhance the depth of images for such content.

The TCL R646 (LCD) is very good for bright room, while the LG QNED90 (LCD) is good.
The TCL R646 outperforms the LG QNED90 in a bright room primarily due to its better handling of reflections, which is very important for maintaining clear picture quality in well-lit environments. While both TVs have similar HDR and SDR brightness, making them suitable for bright rooms, the TCL's superior reflection handling gives it an edge despite the LG having a fair performance in this area.

The LG QNED90 (LCD) and TCL R646 (LCD) are both only fair for sports.
The LG QNED90 has better viewing angles and motion processing, which can make it preferable for sports with wide seating arrangements and fast action, but its reflection handling is only fair, making it less ideal in bright rooms. Meanwhile, the TCL R646 has very good reflection handling and response time, making it suitable for bright environments and fast-moving content, but its narrower viewing angles might limit the viewing experience for those sitting off to the side.

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.
