The Samsung Q80T and Q74T are 2 mid-range 4K QLED TVs from 2020. From the Q80T, the series have been taking big steps in terms of image quality. For example, these TVs have Direct Full Array Local Dimming. This technology makes the black display extra deep and realistic. In combination with the high screen brightness, you see a strong contrast. In this article, we'll highlight the main differences.

Black levels and contrast

Direct Full Array local dimming

Samsung Q80T: Direct Full Array Local Dimming

With Direct Full Array Local Dimming, the backlight is divided into different zones. When the TV shows a dark image, only the areas behind this image dim. Behind the bright parts of the screen, the zones light up brightly. This way, the black display is extra accurate and you see a more powerful contrast between dark and light images. That way, a star shines brightly in a black sky. The Q80T has Direct Full Array Local Dimming 8x. The higher the number, the more local dimming zones, the stronger the contrast.

Dual LED

Samsung Q74T: Dual LED

The backlight of the Samsung Q74T isn't behind the screen, but at the edges. These lights aren't divided into zones, so the black display is less deep and accurate. This makes a star shine less brightly, while the sky looks dark gray instead of pitch black. To improve the contrast, the backlight has Dual LED technology. The TV analyzes the images you're viewing, after which it adjusts the color temperature.

Peak brightness

1500 nits

Samsung Q80T: 1500 nits

The Samsung Q80T has Quantum HDR 1500. This means that it reaches a peak brightness of 1500 nits. This particularly brings out the bright color tones of HDR images. An extra advantage is that you see more subtle details in clear images, like a cloud field in a radiant sky.

500 nits

Samsung Q74T: 500 nits

With around 500 nits, the peak brightness of the Samsung Q74T is slightly lower. When you view standard SDR images from a DVD or TV program for example, the differences with the Q80T are small. When you watch HDR images, the TV is less capable of realistically showing the brightest color tones and subtlest details in clear images.


Object Tracking Sound+

Samsung Q80T: Object Tracking Sound+

Object Tracking Sound+ is a new technology that makes the sound follow the action on the screen. The audio system of this TV has speakers that are directed upwards and downwards. For example, if you look at an image of a landing helicopter, the sound at the bottom of the screen becomes increasingly powerful. This provides an extra realistic movie experience. Note: the 49-inch model doesn't have this technology.

Adaptive Sound+

Samsung Q74T: Adaptive Sound+

With the Q74T, you don't have the Object Tracking Sound technology. Just like the Q80T, the TV does have Adaptive Sound+. This technology adjusts the sound to your usage situation. This is useful when you watch the news or a TV program at a low volume, for example. In this case, the TV automatically ensures that voices sound extra clear.


Thanks to the Full Array Local Dimming technology and the higher peak brightness, the Q80T delivers a stronger contrast than the Q74T. Especially HDR images look extra realistic because of this. Dark images are extra deep and show more subtle details, while bright colors look extra clear. In combination with the extra realistic sound reproduction, this TV is a more suitable choice for movie lovers.
