LG QNED84B 65-inch 4K Mini LED TV vs TCL S4 65" 4K Roku TV

The LG QNED84B is the better TV for picture quality, gaming and HDR. Its Mini LED backlight, 120Hz panel with 144Hz VRR and FreeSync Premium, and Dolby Vision support put it well ahead of the TCL S4, which is a basic 60Hz edge-lit set with no local dimming. The TCL wins on simplicity and inputs: Roku TV is easy to learn, it has four HDMI ports and built-in AirPlay, and its huge owner base reports it as a reliable budget set. Buy the LG if the screen is your main TV and you watch movies or game on it. Buy the TCL if you want a cheap, easy second TV for a bedroom or a casual viewer.

  • Choose the LG QNED84B if you want strong HDR, deep blacks from Mini LED local dimming, and smooth 120Hz gaming with FreeSync and VRR.
  • Choose the TCL S4 if you want a simple Roku interface, four HDMI inputs and AirPlay at the lowest cost, and don't need high refresh or deep blacks.

Questions and answers

Which is better for gaming, the LG QNED84B or the TCL S4?
The LG. It has a 120Hz panel, 144Hz VRR, FreeSync Premium and low input lag, while the TCL S4 is capped at 60Hz with no VRR. For a PS5 or Xbox Series X, the LG shows smoother motion and less tearing.
Is the LG QNED84B worth stepping up to over the TCL S4?
Yes if you watch movies in a dark room or game seriously. Mini LED local dimming, Dolby Vision and the 120Hz panel are real upgrades you will notice. If the TV is for a bright bedroom and casual streaming, the TCL covers the basics.
Which TV is better in a bright room?
The LG QNED84B. Its Mini LED backlight pushes higher brightness and holds up better against window light. The TCL S4 is dimmer and its glossy panel shows more reflections.
Which one has a better smart TV system?
It depends on preference. Roku TV on the TCL is simpler and has a compact remote, which suits casual viewers. webOS on the LG is faster and supports more apps and voice features, but the menus are busier.
Does the TCL S4 support Dolby Vision?
No. The TCL S4 handles HDR10 only. The LG QNED84B supports Dolby Vision, Dolby Atmos and HDR10 Pro, so Dolby Vision content from Netflix and Disney+ looks better on the LG.
Which lasts longer?
Both are LED sets with similar panel lifespans, and neither has a clear reliability edge from the ratings. The LG has more complex backlighting, which adds parts that can fail, while the TCL's simpler design has fewer things to go wrong.
