LG QNED84B Mini LED 4K TV vs TCL QM6K Mini-LED TV

Both are Mini LED 4K sets with 120Hz-or-better panels and strong HDR. The LG QNED84B is the better all-rounder for movies and mixed use: Dolby Vision, Dolby Atmos, webOS, and a 144Hz VRR mode with Motion Booster 288 make it a serious gaming display too. The TCL QM6K leans on QD-Mini LED color, a matte anti-glare screen, and Google TV, and owners consistently praise its blacks and build. Pick the LG for Dolby Vision content and gaming features; pick the TCL if your room is bright and you prefer Google TV.

  • Choose the LG QNED84B if you watch a lot of Dolby Vision movies, game on a console or PC at high frame rates, and want webOS with Google and Apple home support.
  • Choose the TCL QM6K if glare is a problem in your room, you want QD-Mini LED color with up to 500 dimming zones, and you prefer Google TV.

Questions and answers

Which is better for a bright living room?
The TCL QM6K. Its matte screen cuts reflections, and reviewers single out the low glare. The LG is brighter on paper with Mini LED, but its glossy finish shows more reflections.
Which is better for gaming?
Both are strong. The LG lists 144Hz VRR and Motion Booster 288, plus three HDMI inputs. The TCL has a 144Hz native panel and Game Accelerator 240. Pick the LG if you also want Dolby Vision in games.
Does the TCL have Dolby Vision?
No. The QM6K lists HDR10 and HLG. The LG QNED84B supports Dolby Vision, so it is the better pick for Dolby Vision streaming.
Which has better sound out of the box?
The TCL, on paper. It uses an ONKYO system with a built-in subwoofer. The LG lists 174W output and Dolby Atmos. Either way, a soundbar improves both.
Is the LG worth stepping up to?
If you want Dolby Vision, webOS, and a wider choice of sizes up to 100 inches, yes. If glare control and Google TV matter more, the TCL covers those better.
Which lasts longer?
Neither maker publishes a lifespan figure. Owners of both report solid build quality. Panel uniformity and backlight failures are the usual long-term risks on any Mini LED set.
