Contrast ratio problem.

[EpicRocker]

Hello, Forum

 

My name is EpicRocker and I have a bit of a problem. I've been seeing lots of PC videos, peripherals, ect. I have noticed something rather odd and I can't seem to understand. I saw the Linus video on the Surface book (

here is the link. And I noticed something rather odd. When linus said that the screen had a Contrast Ratio of the Surface book was "1700:1" I was confused. Because the other day I saw a Tech of Tommorow video in which he talked about a monitor with 80m:1 contrast ratio. So, which one is it? Is the contrast ratio measured by Millions or the thousands. And if a 80m:1 if better than a 1700:1. I really can't get my head around it; and I want to buy the best monitor with the best contrast ratio. 

 

Sincerely, EpicRocker. 

 

Ps. Love your videos Linus. And I hope I can get and answer on the topic.

I can't believe no one has tried to answer this.

 

The difference lies in how the manufacture chose to advertise the contrast ratio of their screens.

The 80.000.000:1 contrast ration is dynamic contrast, while the 1700:1 is native contrast. 

 

Dynamic contrast is achieved by the monitor sensing what's being displayed and adjusting the backlight accordingly. This can in theory create a very high contrast ration.

In practice, however, it's not always that easy, since adjusting the backlight will ruin either the black or white elements in whatever is being displayed.

There is also little to no standard for how to measure dynamic contrast; rendering the numbers borderline meaningless.

 

Native contrast is the contrast ratio the screen is nativly capable of without backlight adjustments.

 

So, in real life you'll almost always be better of buying a screen with a high native contrast than one with a high dynamic contrast. 

 

Lastly, welcome to the forum.
