Samsung Q70T vs Q80T: Which is Better? [Review]

Samsung LED televisions are nowadays, the most likable TV’s. Because of their ultimate features and properties, they have become popular among people. If we talk about Samsung’s QLED series, you will be amazed to hear that there is a total of 7 series naming Q60T, Q70T, Q75T, Q80T, Q95T, Q800T, and Q950TS.

For getting your hands on the best Samsung TV between the Q70T and Q80T series, first, you need to select the size you want. Like when you read the above review you will get to know about the Samsung Q80T 49 inches model, it doesn’t have all that you need on your Tv. Like it has a simpler sound system, it doesn’t have the 120 Hz panel and it also lacks the Object tracking sound. But as we go up in models like 55 inches model of Q80T is better than Q70T as it has significant features including better improvements in picture and sound. Also, most of us love to watch movies in a dark room, for a better picture, purer black, and uniformity of illumination, then Q80T is the best option than Q70T as it will look more grater and a bit of flare appears when used in a dark room.
And for better sound performance again Q80T is the best option for you to choose.

But here we are about to review and focus on the two series i.e., Q70T and Q80T series. The Q70T series consists of 55 inches (QN55Q70T), 65 inches (QN65Q70T), 75 inches (QN75Q70T), 82 inches (QN82Q70T), 85 inches (QN85Q70T). While that Q80T series consists of 49 inches (QN49Q80T), 65 inches (QN65Q80T), 75 inches (QN75Q80T), and 85 inches (QN85Q80T).

Considering the interesting features of both series, let’s just review them so that if you’re interested in getting one you won’t be in difficulty after reading the review. Below there is complete detail about the similarities and differences between Samsung Q70T vs Q80T series.

Let’s just dig right into the similarities of both televisions. We have here a few main points of similarities between them and we discuss them in detail to help you understand the best in these two amazing technology items.

Difference between Samsung q90t vs Sony x950h.

Panel technology:

The first and foremost similar thing in both the Samsung Q70T vs Q80T is that they use the same panel technology named VA panel which is supported by Quantum Dot Technology. Because of the VA panel technology, they both have the best native contrast ratio, which helps in producing deep black color. As well are already familiar with LEF TV having VA panels that produce deep black. With the features, it also has a flaw as the VA panel is a wide viewing angle and unfortunately, the TV with VA panel technology has ultimate poor side viewing angle coverage. But for producing HDR image more colorful the Quantum Dot Technology support the VA panel a lot.

Motion technology:

Another useful technology is Motion technology. Both Q70T and Q80T have the same motion technology, except the inches model TV of Q80T (QN49Q80T). This model doesn’t have the technology present in it. Both the TVs have the Motion Rate 240 technology and at the same time native refresh rate 120 Hz panel. Including the VRR TECHNOLOGY (Variable Refresh Rate technology), which helps in improving the game experience by reducing the screen tearing.

By better smoothness of the motion, both Q70T and Q80T have BFI (Black Frame Insertion) mode. Coming on to the dimming frequency of Q70T which is 600 Hz and that of Q80T is 960 Hz, for changing this dimming frequency to 120 Hz you need to do some settings. For changing the dimming frequency of Q70T to 120 Hz, you must have to enter in “PC” mode and then in “Game” mode with enabling “Game Motion Plus”.

On the other hand, if you need to change the frequency of Q80T, you must have to enter “Natural “, “Standard “, “Dynamic “and “Game” mode. Also, by entering into “Movie” mode by setting the “picture clarity “to “Auto” and “Custom”, you can change the frequency to 120 Hz.
At the same time, you can change the dimming frequency to 60 Hz by turning on the “LED Clear Motion” mode on both TV.

Image processors:

Both the TVs Q70T and Q80T have enabled the same image processor in them named “Quantum Processor 4K”. The function of the image processor is to enhance the features of the image such as 4KAI Up-Scaling, Adaptive Sound, Adaptive Brightness, and Volume. It also enables the smooth running of the TV.


For the remote, both the Samsung Q70T and Q80T have Samsung Smart Controller TM 2050C. When we look back to the previous models, we found that the Q70R, Q80R, and other last year models also have a similar remote except for a change in the button. The remote looks very small but loaded with smart features having the microphone for voice navigation. This remote can control not only the devices which support HDMI CEC, but rather it can also control the devices which do not support HDMI CEC.

Differences between Samsung Q70T and Q80T

Blacklight technology:

As we discussed above in the similarities of both Q70T and Q80T are that it has the same VA panel technology but when it comes to backlight technology, their backlight technology is different. The Q70T uses the Edge-LED Lit backlight while that or Q80T uses a Direct LED backlight. Another feature is the local dimming feature that Q70T doesn’t have while the Q80T has the full array local dimming feature. The function of the local dimming feature is to improve the TV’s performance by improving the contrast ratio and minimizing blooming when the LED is placed in the darkroom with no lightening.

As we all know most televisions have dimming systems in them for dimming the frequency of the picture. Both these TVs use PWM (Pulse-Width-Modulation) dimming system. But that doesn’t mean that they use the same dimming frequency. For Q80T the dimming frequency is 960 Hz and for Q70T it is 600 Hz.

Ultra-Viewing Angle:

Screen Size q70tScreen Size q80t

Ultra-Viewing technology is designed to improve the side viewing angle of Samsung Q70T and Q80T series TVs. The Q80T by Samsung already has this technology except one of its models 49 inches (QN45Q80T), it doesn’t have the technology present in it. The IPS panel comes with a good side viewing angle but a poor native ratio that is why it is not the best for side viewing. Then we can say that the Q70T has both an excellent contrast ratio as well as a good side viewing angle.

Sound system:

As we are differentiating between the Samsung Q70T and Q80T, a major difference between both is their sound system. The sound system of Q70T differs from Q80T as the Q70T is equipped with the standard sound system which is 2.0 with 20 watts of the total sound input. While if we take a look at the sound system of Q80T, it is equipped with a 2.2.2 channel system with 40 watts of the total sound input. While one of the models from Q80T, the 49 inches (QN49Q80T) it has a 2.2 channel system with 40 watts of the total sound input.

Another major difference between both is their HDR numerical index. When we are talking about the HDR numerical index, we can say higher the HDR numerical index of the Samsung TV, the higher will be the performance of Tv. Hence HDR performance of any Samsung Tv relies on its HDR numerical index. The Samsung Q70T has HDR Output Quantum HDR while the other tv from the series Q80T has Quantum HDR 12X. But the 49 inches model (QN49Q80T) has Quantum HDR 8x.
