What is Quantum HDR explained: Quantum HDR 12x vs 24x

Let’s understand Quantum HDR technology today, because it’s a very interesting technology that many potential buyers just don’t understand.

In general, modern technology in TVs stagnates, I think it is obvious to everyone who at least slightly follows the changes in this industry. The last breakthroughs were in the mid-2010s and now manufacturers have to draw attention to new models with minor improvements and not always these improvements and new technologies are really important. So you need to figure it out if you want to spend your money wisely.

What is Quantum HDR explained

First of all, we should understand that Quantum HDR is a mix of two existing technologies: HDR and Quantum Dots.

You should understand that Quantum HDR is a mix of two existing technologies: HDR and Quantum Dots.

What is HDR? That’s the acronym for High Dynamic Range. HDR affects the two most important factors in TVs – contrast ratio and color accuracy. Contrast demonstrates how bright (or dark) an image on a TV screen can be, while color accuracy affects how similar the colors you get on the screen are to the real colors (i.e. those found in the original content).

The better these two factors are, the more natural and thus more pleasing to the eye the image you get on screen will be.

HDR increases the range of contrast and increases the accuracy of color reproduction. Thus, bright colors can be more vivid (people usually describe this as more “deep” colors) and also on how accurately the original color gamut of the picture will be rendered.

HDR increases the maximum color values for the three base colors: red, green, and blue. As a result, all the other colors that come from the mix of these base colors will also be brighter and more saturated.

Quantum means that the TV display is made using Quantum Dot technology.

In short, Quantum Dot screens (they’re usually named as QLED) are LED displays that use a different type of backlight. If the standard LED backlight is a huge number of diodes, which emit white light, in the QLED screens diodes emit a blue glow.

As a result, such TVs have higher brightness and contrast (I mean peak brightness of course), because the blue color is one of the three base colors, unlike white.

That is, Quantum HDR technology is a TV with QLED screens that have support for HDR technology.

What is Quantum HDR 12x

Now let’s talk about what Quantum HDR 12x and the other numbers behind the name of this technology mean.

It took me quite a long time, but now I know the answer and it was quite simple.
12x (as well as any other numbers after Quantum HDR) means the maximum (peak) brightness the TV can show you.

This is calculated by the formula X x 100. That is, Quantum HDR 12x means that your TV can provide peak brightness of 12×100 nits, which is equal to 1200 nits.

What is Quantum HDR 16x

Similar to Quantum HDR 12x, for Quantum HDR 16x the peak brightness will be 16 x 100 equal to 1600 nits.

This, in my opinion, is an excellent brightness, which will be enough for almost any viewer, but the manufacturers now do not stop at this value and offer Quantum HDR 24x and even Quantum HDR 32x.

Of course, the higher the peak brightness value, the more expensive such a TV will be, so keep that in mind.

What is Quantum HDR 24x

Using the same formula, we can easily understand that the peak brightness for Quantum HDR 24x will be 2400 nits (24 x 100).

Of course, the higher the brightness the better, but I don’t think you will be watching TV at maximum brightness, so think twice before buying such a TV.

In any case, if you have the money, such a TV will not be superfluous, you can make the brightness lower in any situation. However, the question is how much such a purchase will be impactful.

What is Quantum HDR 32x

TVs with these displays belong to the high-end class of expensive TVs, because their maximum brightness of 3200 nits.

Personally, I would be uncomfortable looking at a TV screen with such a high brightness, especially if you watch it with low ambient light.

However, if you are willing to spend the money, go for it. Just know that most of the time you will be limiting the brightness at 2000-2400 nits.

What is Quantum HDR 40x

I haven’t found any TVs with these tech specs yet, but I’m sure they will show up in the future. At least, QLED screens can give you peak brightness up to 4000 nits, but I don’t think that’s really impactful.

I don’t mean that you shouldn’t buy the brightest TV on the market, I just think we should use our money wisely, so don’t rush for the as high brightness as possible, as there’s a great chance you would never use it.

What is Quantum HDR 8x

Yeah, such TVs also exist. But the problem is that the peak brightness of 800 nits is quite low, so I don’t think you should buy a TV with such a display.

In my opinion, it’s better to take a look on Quantum HDR 12x/Quantum HDR 16x TVs, that’s the best displays now in terms of price/quality ratio.

Is there a difference between Quantum HDR and HDR?

Yeah, it is. The HDR is the name of a technology that’s enhancing your TV’s display brightness and color accuracy, while Quantum HDR means QLED TV with HDR support.

In fact, there’s no sense in HDR technology in LED TVs, as their peak brightness is around 1000-1200 nits, so HDR simply can’t impact the picture quality in the right way, so the only way to get HDR benefits is purchase QLED TV (Quantum HDR).
