The LG UP8000 is a lower midrange-priced TV that is typically much less expensive than the TCL R646, which is an upper midrange-priced TV. The LG’s performance in bright rooms is reasonable, but it may perform poorly in a dark room compared to the TCL. The TCL offers superior overall picture quality and is better for dark room viewing but comes at a higher cost. If gaming is a priority, the TCL has a higher gaming score and supports a higher refresh rate, which is better for fast-paced content. For bright room usage, the TCL also scores higher and has better reflection handling. Both TVs support HDR, but the TCL additionally supports Dolby Vision, HDR10+, and has a higher brightness capability for HDR content, which can make HDR movies and shows look more impressive. If you're on a tighter budget, prefer to spend less, and need a TV that's adequate for a variety of content, the LG UP8000 could be a suitable choice. However, the TCL R646 may be the better option if you're looking for higher performance, particularly for gaming and HDR content, and are willing to pay more for these features. Give Feedback

The TCL R646 (LCD) is good for movies & TV, while the LG UP8000 (LCD) is poor.
The TCL R646 delivers a more immersive cinematic experience owing to its superior contrast, effective local dimming, and better black uniformity compared to the LG UP8000, which severely lacks in these critical areas for movie watching. Additionally, the R646's better performance in color reproduction out of the box, color volume, and gray uniformity also contribute to its suitability for movies and cinematic TV over the UP8000, which falls short, despite both having limitations in viewing angles.

The TCL R646 (LCD) is very good for bright room, while the LG UP8000 (LCD) is poor.
The TCL R646 excels in a bright room primarily due to its higher SDR and HDR brightness, which combats glare, and very good reflection handling, providing a clear picture even in well-lit conditions. In contrast, the LG UP8000 performs less effectively in bright environments because of its lower brightness levels and merely good reflection handling, which may result in a more washed-out image when viewed in brightly lit rooms.

"What we liked on this one was the very sharp 4K images it could display, its good up-scaling capabilities, nice viewing angles and extremely low input lag. Lastly the new webOS 6.0 is great even if it needs some time to get your bearings while the redesigned Magic Remote feels fresh even if functionality remains the same."

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.
