Nits are important for a variety of reasons. If you're looking for a display that you can use outdoors or in other well-lit areas, then you should look for one with a high nit rating. To put it simply, the higher the nit rating, the brighter and more visible the display will be in bright conditions. Meanwhile, candelas take into account the entire area that is emitting light. On the other hand, Nits and candelas are different because nits measure the brightness at one point. In other words, nits tell you how bright the light appears to be, while lumens tell you how much light is actually being emitted. Nits measure the intensity of that light. This means that the colors and contrast in the content have been specifically designed to take advantage of an HDR screen. In order to take advantage of this increased brightness, you need content that is also high-dynamic range (HDR). This results in a more realistic and lifelike image. On the other hand, an HDR TV has a much wider range of colors and can display more shades of each color. A regular old LCD TV has a limited range of colors and contrast that it can display. The difference between these two types of screens is significant. For example, a standard laptop screen might have a brightness of 200 nits, while an HDR TV can have up to 1,000 nits or more. The word “nit” comes from the Latin word “nitere” which means “to shine.” In other words, a nit is how bright a screen appears to one human eye. Candela, in turn, is the unit measurement for light intensity. What is a Nit of Brightness?Ī nit is a unit of measurement that equals one candela per square meter. In contrast, the sun is a lot brighter since it produces almost 409,000 lumens per square inch, or about 40.9 million candelas. But different types of light sources can produce vastly different numbers of candelas.įor example, a 100-watt lightbulb emits about 1,600 lumens, or 16 candelas. One candela is about the same intensity of light as that produced by a common candle. ![]() If you're wondering why it sounds a lot like candle, that's because the word comes from the Latin candela, which means "candle." It's basically the "brightness" of a light source in a specific direction. Here’s an in-depth look at these two measurements: CandelasĪ candela is the unit of measurement for light intensity in a particular direction. This basically means it’s a measurement of how bright the light appears to be when you are looking at it from a specific angle. Candelas and Nits are typically mentioned when talking about screen brightness and they both refer to the amount of light that is emitted from a certain area or a given direction. But what is a nit, exactly? How bright is too bright, and how do we measure it? Back to Basics: Candelas and Nitsīefore we delve into nits, we have to understand candelas first. If you've ever tried shopping for a TV or a similar device, you may have seen a unit of measure called "nit" thrown around. The higher the number of nits, the brighter the object or surface will appear.īelieve it or not, modern screens, including the ones on our smartphones, televisions, and laptops, are getting brighter. ![]() Understanding nits is important if you want to buy a new television or monitor, or if you want to know how bright your current display is.Nits is a unit of measurement that refers to the amount of light that is emitted from a surface or object.Black levels have a linear scaling with your brightness, so increasing your brightness from 100 nits to 200 nits will also make your black appear twice as bright. also use 100 nits or slightly brighter as a reference when calibrating and testing monitors.Īlso keep in mind that increasing your brightness will also raise black levels. Most reviewers like Rtings, DisplayNinja, Prad, etc. Many professionals recommend to set the brightness between 100 and 150 nits for SDR. You will have much less eye fatigue when you get used to a dimmer display. Many people think 100-150 nits is too dim, but let your eyes get used to it for an hour or so and they will thank you in the long run. Higher nits become more important for HDR content, where you want to hit the 1000 Nit mark for a "real" HDR experience (when combined with proper local dimming). It's not too dim for daylight use (even with a window directly opposed to the display) and not too bright for use in the evening/night. I calibrate all my displays to consistently end up at 150 nits. ![]()
