The rising China-based TV maker’s all-new 2019 lineup channels high-end Samsung and challenges midpriced Vizio in a bid for TV supremacy.

TV nerds like myself have waited a long time for details on TCL’s 2019 televisions, and now that the TV maker has finally unveiled its new sets, they don’t disappoint. Two new models — the high-end TCL 8 series with fancy mini-LED tech and an upgraded TCL 6 series that adds QLED color — are immediate contenders for the best TVs of 2019. And of course, every new TCL TV has built-in Roku TV, my favorite smart TV system.

TCL has become one of the most popular TV brands in the US, growing by more than 60 percent in 2017 and 2018 according to market research firm NPD, trailing only Samsung and Vizio in units sold. During that time, however, its growth has mostly come from entry-level models like the 3 series and 4 series — among my top choices for budget buyers — but not in midrange and high-end sets.

Now the company aims to broaden its appeal to video-quality aficionados and others willing to pay more. “With the 8- and 6-Series powered by the latest QLED color technology, there are few TVs available that can match their cinematic picture quality,” said Chris Larson, senior vice president of TCL.

That claim has merit. With the 2018 6 series, my Editors’ Choice among LCD TVs, the company demonstrated it can nail the sweet spot between price and image quality. The new versions look even better on paper. Here’s all the new 2019 TVs TCL announced today.
