Samsung M70H 43" Mini LED 4K TV vs TCL Q3K Series 1080p QLED Smart TV

The Samsung M70H is the better TV by a wide margin: 4K resolution, Mini LED backlight with local dimming, and three HDMI ports against a 1080p QLED panel with two. The TCL Q3K is a small, basic set that suits a bedroom or a secondary room where a 1080p picture is enough. Owners of both rate them 4.4 out of 5, but the Samsung's picture technology and Tizen platform put it in a different class.

  • Choose the Samsung M70H if you want a true 4K picture with Mini LED contrast, local dimming and a full smart TV platform for a main room.
  • Choose the TCL Q3K if you need a compact, simple 1080p smart TV for a bedroom, kitchen or spare room and 4K does not matter.

Questions and answers

Which is better for a main living room?
The Samsung M70H. Its 4K resolution, Mini LED backlight and local dimming give a sharper, higher-contrast picture than the TCL's 1080p panel.
Is the TCL Q3K good enough for a bedroom?
Yes. At 1080p on a compact screen, the picture is fine for casual viewing, and Google TV covers the main streaming apps.
Which has better contrast?
The Samsung. Mini LED with local dimming dims dark areas for deeper blacks; the TCL uses a direct LED backlight without local dimming.
Can I wall mount either TV?
The Samsung supports standard VESA mounting. The TCL Q3K is listed as not VESA compatible and is designed to stand freestanding.
Is the Samsung worth stepping up to over the TCL?
For a main TV, yes. You get 4K, local dimming, a third HDMI port and a fuller smart platform. For a spare room, the TCL is enough.
Which is better for gaming?
The Samsung, mainly for its 4K resolution and extra HDMI port. Both are 60 Hz, so neither targets high-frame-rate gaming.
