Consensus

ReasonS to Buy

  • Outstanding picture quality
    • With up to 97.31% coverage of the DCI P3 color space, the QM850G TV offers sharp and accurate color reproduction, yielding pristine picture quality when watching dynamic content. This places it in the top 20% of its category in this regard.

  • Spectacular brightness and contrast ratio
    • The QM850G is great for daytime viewing, courtesy of its impressive 1620-nit brightness rating, placing it among other top TVs in the category. The display’s 5,531:1 contrast ratio is also well above average. This, plus its local dimming feature, gives you deep, inky blacks.

  • Rapid response time
    • Motion blur on the QM850G QLED is very hard to notice thanks to a rapid 6.6ms response time. This makes it among the best picks in its category for enjoying fast-action gaming.

  • Super low input lag
    • Gamers will enjoy the immediate relay of feedback when gaming on the QM850G TV thanks to its super low 14.3ms input lag. This, and its HDMI 2.1 ports, make it a highly considerable choice for competitive gaming, as it ranks highly for its low input lag compared to other certified, tested TVs.

Reason to Avoid

  • Disappointing viewing angles
    • Images have a significant deterioration in quality when viewed from the side, as brightness loss starts to occur at 32° off center.

The TCL QM850G offers a total of 1,080 local dimming zones to enhance its contrast, which is more than the 160 provided by the TCL Q750G. Also worth noting is that the two TVs have different contrast levels, as the QM850G has a 5,533:1 native contrast ratio, while the Q750G has a 9,614:1 native contrast ratio. This means that the Q750G offers way deeper black levels and is ideal for dark room viewing. Check out what else it has to offer through our TCL Q750G QLED TV review, but if you’d not mind a more basic alternative with a lower 720p resolution compared to the QM850G’s 4K resolution, then go ahead and check out our TCL 3 Series review.
