Samsung M70H Mini LED 4K TV vs TCL S4 65" 4K Roku TV

The TCL S4 is the bigger screen: 65 inches against 55, and it runs Roku TV, which most people find the simplest smart interface. The Samsung M70H is the better picture and the better gaming set, with Mini LED backlighting, HDR10+ and a 48-60Hz variable refresh rate, where the TCL has no local dimming and plain HDR. Owners rate the TCL well for value and ease of use, but it is a basic edge-lit panel; the Samsung is the step up if picture quality matters more than size.

  • Choose the Samsung M70H if you sit close enough that 55 inches fills the wall and you want Mini LED contrast, HDR10+ and smoother console gaming.
  • Choose the TCL S4 if you want the largest screen for the room, four HDMI ports and the Roku interface with AirPlay.

With over 45,000 ratings averaging 4.3 out of 5, owners mostly treat the S4 as good value for the size. Praise centers on the Roku interface and easy setup; complaints tend to be about picture quality limits and sound.

Questions and answers

Which is better for a bright living room?
The Samsung M70H. Its Mini LED backlight pushes more brightness and holds contrast better in daylight. The TCL S4 is a standard edge-lit panel and washes out more in a sunlit room.
Which is better for gaming?
The Samsung. It supports variable refresh rate from 48 to 60Hz and a 120Hz motion mode, which reduces tearing and blur. The TCL S4 is fixed at 60Hz with no VRR, fine for casual play but not for fast shooters.
Is the TCL worth it for the bigger screen?
Yes, if distance is the priority. At typical couch distance the extra 10 inches is noticeable, and Roku is easier for a household to use. You give up contrast, HDR10+ and gaming features to get it.
Which lasts longer?
Neither has a clear edge in lifespan. Both are LED sets from major brands with similar panel technology. The Samsung adds Mini LED hardware, which is more complex, but failure rates on either are low.
Do I need a soundbar with either?
Both have modest built-in speakers, so a soundbar helps either one. The Samsung has 20W across two channels and Bluetooth for wireless audio; the TCL offers Dolby Digital Plus and an optical output for a wired soundbar.
Is the Samsung worth stepping up to?
If you care about picture quality, yes. Mini LED, HDR10+ and VRR are real upgrades over the TCL's basic panel. If you mainly watch cable and streaming in a bright room and want the biggest screen, the TCL covers it.
