TCL S4 55" 4K Roku TV vs VIZIO VQM55C-10 55" Mini LED QLED TV

The VIZIO VQM55C-10 is the better picture for the money: Mini LED backlighting, QLED color and Dolby Vision give it deeper blacks and brighter highlights than the TCL S4's plain LED panel. The TCL S4 wins on simplicity and track record, with Roku TV's clean interface and a huge base of 4.4-star owner ratings. Both are 60 Hz 4K sets, so neither is a gaming upgrade. Buy the VIZIO for movie nights in a darker room; buy the TCL if you want the easiest smart TV and proven reliability.

  • Choose the TCL S4 if you want the simplest smart TV interface, Roku's huge app selection and a set with a long record of solid owner satisfaction.
  • Choose the VIZIO VQM55C-10 if picture quality matters most: Mini LED contrast, QLED color, Dolby Vision and a five-year warranty.

Questions and answers

Which has the better picture, the TCL S4 or the VIZIO VQM55C-10?
The VIZIO. Its Mini LED backlight and QLED layer produce deeper blacks, higher brightness and richer color, and it adds Dolby Vision. The TCL S4 is a standard LED set with good but not standout contrast.
Is the VIZIO worth stepping up to over the TCL?
Yes if you watch movies or HDR shows in a dim room, where the contrast and Dolby Vision show. If you mainly want a simple TV for streaming and broadcast, the TCL's Roku interface is easier and its owner track record is much larger.
Which is easier to use?
The TCL. Roku TV has a straightforward home screen, a short remote and quick app access. VIZIO's SmartCast works fine but takes more navigation and leans on its own free channels.
Which lasts longer?
The VIZIO carries a five-year warranty, which is unusually long and the stronger long-term bet on paper. The TCL has a standard one-year warranty, but its very large pool of owner ratings shows few complaints over time.
Are either of these good for gaming?
Both are 60 Hz panels, so neither suits high-frame-rate console gaming. The VIZIO's HDMI 2.1 ports are more future-proof for connections, but the refresh rate is the real limit on both.
Do both support voice assistants?
Yes. The TCL works with Siri, Alexa and Google Assistant through Roku, and the VIZIO supports Alexa, Google Home and Apple Home. The VIZIO includes a voice remote.
