TCL QM6K QD-Mini LED Google TV vs TCL S4 65" 4K Roku TV

The QM6K is the better TV for picture quality, gaming and HDR. Its QD-Mini LED backlight with local dimming, wide color and 144Hz native panel beat the S4's edge-lit, 60Hz panel on contrast, brightness and motion. The S4 is a basic 4K set with Roku's simple interface, and its 45,000-plus ratings show it is a proven, easy pick for a secondary room. Buy the QM6K for a main room or console gaming; buy the S4 for a bedroom or casual viewing where a simple smart system matters more than deep blacks.

  • Choose the TCL QM6K if you want strong contrast, bright HDR highlights and smooth 120Hz-plus gaming from a main-room TV.
  • Choose the TCL S4 if you want a simple Roku smart TV for casual viewing in a bedroom, kitchen or spare room.

Questions and answers

Which is better for gaming?
The QM6K. Its 144Hz native panel, VRR and Game Accelerator 240 give smoother motion and lower lag than the S4's 60Hz panel.
Which has better picture quality in a dark room?
The QM6K. Local dimming and Mini LED backlighting produce deeper blacks and less blooming. The S4 is edge-lit with no local dimming, so dark scenes look washed out.
Is the QM6K worth stepping up to from the S4?
Yes for a main room. You gain local dimming, QLED color, Dolby Vision, a 144Hz panel and much better sound. The S4 only makes sense if you want the simplest interface and casual viewing.
Which lasts longer?
Neither has a clear edge on lifespan. The S4 has far more owner ratings over more years, which suggests proven reliability. The QM6K is newer, so its long-term record is shorter.
Which is better for a bright room?
The QM6K handles reflections and bright HDR better thanks to its higher brightness. The S4 can look dim and washed out in a sunlit room.
Do both support voice assistants?
Yes. The QM6K runs Google TV with Google Assistant, Alexa and Siri support. The S4 runs Roku TV with voice through Siri, Alexa and Google, plus AirPlay.
