QM851G (65-inch)

The QM851G is TCL's brightness monster, a mini-LED with an unusually high zone count and quantum-dot color that competes directly with the Hisense U8N for the value-flagship crown. It can hit roughly 2,000 nits, making it one of the brightest TVs you can buy at any price, and it backs that up with Dolby Vision, HDR10+, and a 144Hz panel for gaming. The Google TV platform is the same as on most budget sets, which means it works well but is not the snappiest, and as with all aggressive mini-LEDs you will occasionally notice blooming. If your priority is maximum HDR impact in a bright room without spending flagship money, this and the U8N are the two to cross-shop.

How the Buy-timing Score is calculated

We combine today's price position within this product's own 12-month range, its distance from the all-time low, and the recent trend. The score reflects price timing and is the same in every market; only the displayed prices and retailers change. We never accept payment to change a score. Read the full methodology →
