Samsung Q90T vs Q80T – Ultimate Comparison 2023

While purchasing an extravagant 4K QLED TV, the thought popped up in our minds, if it has to be a flagship gadget of the series or the economic representative can work too? I wrote this blog to compare Samsung Q90T vs Q80T by highlighting the features that might reflect both TVs’ performance.

Differences between Q90T & Q80T

Before we get into the differences, I’d like to mention that both LEDs are elite 4k sets with a couple of changes. But the question is: Do these televisions make sufficient modifications for the price? To get the answer, you’ve to stick to this article till the end!

Both TVs come in a posh and glossy black body, which gives aesthetically pleasing vibes. The front bezel is similar, but if you look at them from the side, you’ll notice that the Q80T is curvy from the back, while the Q90T is flat.

It does make a difference in mounting; indubitably, Q80T is a little deeper.

Another difference is the pedestal, also called the pedestal TV mount. It is a stand on which you can mount your TV. The two devices boast center mounting, which is excellent, but 90T has a curved or sneaker look while 80T is angular.

The Q80T is slightly shorter than the 90s because of the pedestal. That’s not a bad thing; it’s just a variance between two.

Sound System

Samsung QLED TVs have a splendid built-in sound system, which will convert your lounge into a movie theatre. Both of these gadgets get good power and supply appreciated sound. However, the Q80T boasts a 2.2.2 channel system, while Q90T has a 4.2.2 system.

In other terms, the 90s delivered a more rounded out and bulging sound than the 80s. The Bass of both TVs is similar, but I found the 90s sound more detailed in highs.

You can only notice this difference if you place them side to side, or else both have a boundless sound system.


Display-wise, the QLED displays by Samsung deliver top-end brightness and deeper darkness levels, which is better for your eyes’ health. When I compared both screens side by side, I got to know that greens and blues pop up more in the 80s than in the 90s. At the same time, the red seems more intense and prominent on Q90T.

Though both TVs bring 120 Hz total array panels, dimming zones are higher in Q90T. Samsung has not revealed the exact figures, but the Q90T displays HDR content better than the other model.

The HDR content refers to more detail of the picture, which improves the contrast ratio and dimming, and makes the device suitable for watching shows and movies. Most of you will not notice this unless you have the screens next to each other, which will not likely happen at home.

Input Power

Input Power or AC Input Power is the amount of energy a particular electronic device takes inside to perform. If a TV requires less input power to run, it means it is more energy-efficient.

Both of these flagship TVs by Samsung are power-efficient and will cut down your extra electricity cost.

Numerically, the AC input power of Q90T is 110VAC/60Hz, which is slightly lower than that of Q80T, which is 120VAC/50, 60Hz. In comparison, the Q90T is the winner because it is a little more energy efficient.


In the modern world, technology has evolved, and every day, you see a more innovative and sleekier design of gadgets. In this context, these Samsung televisions are streamlined, shiny, and lightweight.

The Q90T weighs 44.4 lbs. or 20.1 Kg without a stand and 53.8 lbs. or 24.4 Kg withstand. Contrarily, the Q80T weighs 39.5 lbs. or 17.9 Kg without stand and 46.3 lbs. or 21 Kg with stand.

But the question is: How heavy should a TV be? The weight of a TV differs with size and brand. A TV can weigh from 1 Kg to 50Kg and above.

Lightweight TVs are usually preferred because they are at low risk of falling from the wall and are thinner and more stylish. The 80s are lighter than the 90s!

Virtual Assistant Support

A virtual assistant is a contractor that provides services to the user and makes the device and application more convenient and suitable. It is built-in both TV models.

But I found a slight difference here that Q90T has Google Assistant and Amazon Alexa; however, the Q80T has Samsung Bixby with Amazon Alexa. All of those do work without a fault!

Input Lag

Input Lag is the time required to send an electronic signal to display the corresponding action. It is also called latency lag. If a device has more input lag, it’ll take a long time to display the frame, which is a disadvantage.

The Samsung Q90T and Q80T boast good input lag and perform quickly. Authentically, the 90s has 11ms input lag, and the 80s has 14ms input lag. Thus, the Q90T model is the winner. I suggest gamers consider the least lag time.


While buying a flagship device, people mostly go for large sizes to enjoy the picture along the right lines. Besides, if you’re looking for a smaller screen, then Q80T has got you because it is available in 49 inches too. Other available sizes are 55 inches, 65 inches, 75 inches, and 85 inches (in both models).


Which is better: QLED or crystal UHD?

QLED is better than crystal UHD because it is brighter and delivers improved color quality. I would highly recommend you to buy a QLED television to experience better results. However, the models which boast QLED are pricier than the ones with crystal UHD.

Which is the best TV brand, 2023?

While purchasing a TV, brand name does matter! Because a branded television comes with a moral warranty and substantial results. In today’s TV market, Samsung is the top name as it has good recognition and remarks. LG is also at its climax in the TV manufacturing industry list.

What are TV brands not made in China?

Mostly, American buyers don’t rely on Chinese-manufactured products. In this sequence, we have TV brands that are non-Chinese—for example, Samsung, Sony, VIZIO, and LG.


In both models, the features are enough to justify the cost! I noticed significant differences in sound system, light dimming, weight, HDR content, and size.

Which one is better? Overall, the Q90T model is somewhat better than Q80T in brightness, HDR performance, and display quality. However, it is pricier than the Q80T.

That’s all, folks!
