Our take on the Samsung 55" Class Neo QLED 4K QN70F Samsung Vision AI Mini LED Smart TV (2025)

The Samsung QN70F is a 55-inch 4K Neo QLED smart TV with a Mini LED backlight, Quantum HDR and the Tizen platform with Samsung Vision AI. It has a 120Hz-class panel with VRR and eARC for gaming and soundbars, plus AirPlay, Miracast and Alexa, Google Assistant and SmartThings control. It sits below Samsung's QN90 series: it lacks local dimming, so black levels and contrast in dark scenes are weaker than pricier Neo QLED sets, and its 20W speakers are modest. It suits buyers who want a bright, colorful Samsung 4K TV with gaming features without stepping up to the flagship line.

Questions and answers

Does the QN70F have local dimming?
No. The spec sheet lists no local dimming, so contrast in dark scenes is weaker than on Samsung sets with full-array dimming.
Is it good for gaming?
It supports VRR and eARC, which help with consoles and soundbars. It does not support HFR, so very high frame rates are capped.
What is in the box?
The TV, its stand, remote and power cable. A wall mount is not included, though the set is VESA-mountable.
Can I use AirPlay and Alexa with it?
Yes. It supports AirPlay, Miracast, Amazon Alexa, Google Assistant and Samsung SmartThings.
How does it compare with the QN90 series?
The QN90 line adds local dimming and stronger sound. The QN70F keeps the Mini LED brightness and color at a lower tier.
Do I need a soundbar?
The built-in 20W speakers are modest. Most owners add a soundbar over eARC for fuller sound.
