Roku Plus Series 55" QLED Mini-LED TV vs TCL S4-Series 55" 4K Roku TV

Buy the Roku Plus Series if picture quality matters to you: its QLED panel with Mini-LED backlighting and Dolby Vision produces deeper blacks, higher brightness and better contrast than the TCL S4, and it adds Dolby Atmos sound and a hands-free voice remote. The TCL S4 is the safer budget pick for a second room or a casual viewer, with a huge track record of 10,000-plus owner ratings at 4.5 stars and the same simple Roku interface. Both run Roku OS with four HDMI inputs, so the real gap is the panel and audio, not the software.

  • Choose the Roku Plus Series if you want the better picture and sound in a bright room and will use the hands-free voice remote.
  • Choose the TCL S4 if you want a dependable everyday 4K Roku TV and the picture upgrade is not worth the extra spend to you.

Questions and answers

Which has the better picture for movies in a dark room?
The Roku Plus Series. Its Mini-LED backlight and Dolby Vision give deeper blacks and better contrast, while the TCL S4 has no local dimming and only HDR10.
Do both run the same smart TV software?
Yes. Both use Roku OS, so the home screen, app store and voice search work the same way. The difference is the remote: the Roku Plus remote works hands-free.
Which is better for gaming?
Neither is a gaming set. Both are 60 Hz with no HDMI 2.1 features listed, so fast console games will look similar on either. Pick the Roku Plus for the better HDR picture.
Is the Roku Plus Series worth stepping up to?
If you watch a lot of HDR movies or have a bright room, yes. The QLED panel, Mini-LED backlight and Atmos sound are real upgrades over the TCL S4.
Which lasts longer?
Neither brand publishes a lifespan figure. The TCL S4 has far more owner ratings, which gives a broader reliability picture, but both are entry-level to mid-range sets with similar expected service life.
Can I use an antenna with these TVs?
The TCL S4 lists a built-in ATSC tuner for antenna and cable. The Roku Plus Series specs do not list a tuner, so check before relying on over-the-air TV.
