Samsung QN90B vs Q70B: Picture Quality​

As we've mentioned before in other reviews, the biggest highlight of the Samsung QN90B comes from its Mini LED lighting system, a backlighting method that puts down more and smaller LEDs in the screen and therefore provides more precise localized light control. This results in higher brightness and contrast. Its high peak brightness is enough to combat glare in bright rooms, giving high-quality image color even when viewed in daylight or with lights on.

To improve the viewing angle of the screen, Samsung added a wide viewing angle layer to the QN90B, but it also reduces the native contrast ratio. However, its excellent local dimming feature can greatly improve the contrast ratio and render deep blacks in dark scenes.

The Samsung QN90B offers impressive HDR brightness for a satisfying HDR experience whether watching movies or playing games.

The Samsung Q70B has excellent contrast and is capable of rendering deep blacks in dark scenes, but it does not have a local dimming function. For its price, the Q70B offers satisfactory brightness, enough to overcome glare in bright environments. It has good HDR brightness and color, providing satisfactory images for both games and movies.

However, the Q70B has a narrow viewing angle, and if you move away from the center of the screen, the TV's image color, contrast and brightness, etc., will be reduced, making it unsuitable for wide seating arrangements. On the other hand, the Samsung QN90B has a decent viewing angle, but the 43-inch and 50-inch models have poorer viewing angles because they lack a super viewing layer.

Samsung QN90B vs Q70B: Sound​

The Samsung QN90B TV has a good sound response frequency, and the built-in 4.2.2 60W speakers don't have many distortions. But the sound lacks some punch.

The Samsung Q70B has a built-in 2.0 20W speaker, so the speaker is not as loud as the QN90B and lacks bass.

If you want to get a better sound experience, you need a soundbar for your TV.
