How to Determine Your Display's Brightness in Nits?: A Comprehensive Guide

Imagine sitting at your desk, working, or viewing your favorite show, and suddenly, the screen brightness is off. This occurs when the brightness seems too bright or too dull, making reading or focusing on work difficult. Have you ever wondered how to tell your display's nits? Nit is one of the units for measuring screen brightness, and if you know how to determine nits in your view display, you will be able to screen your perfect look.

In this guide, we'll break down everything you need to know about monitor brightness levels, screen luminance, and how to measure it accurately using different tools and methods.

What Are Nits and Why Are They Important?

Before discussing how to determine screen brightness, let's understand the term "nits." Nits are nothing but a measure of luminance or brightness in units to measure the amount of light that a display is emitting. When referring to the screen brightness in nits, it essentially means how bright the screen will go under specific conditions.


Knowing the brightness of your screen in nits is important as it affects how you will view content on your display. For instance, if you use your device when it's bright outside, for example, you require a higher number of nits to have better visibility whereas in a dark room, lower nits might be more comfortable. To break it all down, let's discuss how to check screen brightness in nits and why.

How to Check Your Display's Brightness in Nits

There are a few ways to measure your screen's brightness by nits measurement tools, and the choice that you will make depends on what you are exactly looking for and what equipment is available. Here is how you can go about it:

1. Check the Manufacturer's Specifications

One way of finding out your screen's brightness in nits is by reading the instructions or specifications included with the product. Manufacturers usually publish this information, so you do not have to measure it yourself. This is the most direct method if you need a quick answer.

2. Use a Colorimeter for Screen Brightness

If you are looking for something that is a lot more accurate, then a colorimeter for screen brightness would be your best choice. This device directly measures the light emitted by the screen in nits. With a colorimeter, it detects the color and brightness of each pixel on the screen and gives an exact reading.

There are many different models; while they might be a bit pricey, they are the best option if you're serious about monitor luminance measurement. A colorimeter will allow you to calibrate your monitor to ensure you're getting the right brightness levels for your specific needs.

3. Use Brightness Calibration Software

Another possibility is to use brightness calibration software that supports your computer. These utilities will refine your monitor's brightness calibration and provide you with a nits measurement for your screen. They are not anywhere near as accurate, but they can be a good and extremely cost-effective option if you only need minor tweaking.

4. Smartphone Apps (Approximate Measurement)

If one does not wish to spend money on professional tools, smartphone apps are available that can approximate the brightness of your screen. Such apps can give an approximate idea of your monitor brightness levels. However, such apps lack the sharpness of professional brightness measurement tools, like colorimeters or calibration software.

Steps to Calibrate Monitor Brightness

Now that you know how to check your screen’s brightness in nits, let’s talk about how to calibrate your monitor brightness for the best results.

1. Adjust the Brightness Manually

Simply adjust the brightness manually using your monitor's on-screen menu or computer's display calibration settings. Aim for a brightness level that suits your environment. If you're in a highly lit room, higher screen brightness units would be quite necessary. Dimly lit rooms may prefer lower brightness.

2. Use Calibration Tools

Once you have the basic brightness set, the appropriate brightness calibration software or a colorimeter will do the precise setting. This software tool will ensure your monitor shows the correct amount of color and light balance, so you're guaranteed a comfortable setting for either working or viewing content.

3. Test Under Different Lighting Conditions

Do not forget that the brightness of the monitor screen will appear differently depending on the surroundings. Try out the screen in several lighting conditions to make sure that the brightness works out well in all lighting. You may need to change the brightness depending on whether it is indoors or outdoors or in a dark room.

What Is a Good Nit Value for a Monitor?

Ideally, what is a good nit value for a monitor? It depends on how you're gonna be using it. For general indoor uses, a monitor with a brightness of about 200-300 nits is usually sufficient. However, if you're going to use your screen outside, or for HDR content, you want something with at least 400 nits. More nits mean better visibility in brighter environments, but they may not always be required indoors.

Why Does Your Monitor's Brightness Vary?

Do you ever notice that the brightness you set on your screen changes depending on the location? That is because perceived screen brightness is heavily influenced by ambient lighting. The same screen that was perfectly bright in a dark room may seem pretty dim when you switch to a bright location.

To combat this, you can adjust your display brightness standards using calibration software to ensure consistent visibility, no matter where you are.

Are Higher Nits Always Better?

Most people think that higher nits measurement means a better display, which is not always true. Many generally feel high nits improve the outdoor visibility of the screen while too much brightness can cause eye strain indoors. It's all about getting optimal screen brightness settings for your environment.


For instance, excessive brightness indoors can cause glare, making it harder to focus. On the other hand, low brightness can strain your eyes when viewing your display for long periods. Always aim to calibrate your screen to match your environment for the best experience.

Conclusion: Achieve Optimal Screen Brightness with the Right Tools

Understanding how to tell your display’s nits and using the right nits measurement tools ensures that your screen performs at its best, whether you're indoors, outdoors, or in between. Whether you're working, gaming, or watching videos, screen brightness plays a big role in comfort and visual quality.

If you want the best monitor brightness levels, consider investing in a colorimeter for screen brightness or using professional brightness calibration software. Make sure to adjust your screen's settings to suit your environment and preferences.

FAQs (Frequently Asked Questions)

Q1: What are nits, and why are they important for screen brightness?

A: Nits measure the brightness or luminance of a screen. Knowing your display's nits helps ensure the screen is visible in various lighting conditions and prevents eye strain.

Q2: How can I check my screen’s brightness in nits?

A: You can check your screen’s brightness by using manufacturer specifications, calibration tools like colorimeters, or brightness calibration software.

Q3: What is a good nit value for a monitor?

A: For general use, 200-300 nits is adequate, while 400+ nits is recommended for outdoor or HDR displays.

Q4: Can I use apps to measure screen brightness?

A: Yes, but smartphone apps provide approximate measurements, and they aren’t as accurate as professional tools like colorimeters.

Q5: Why does my monitor’s brightness vary between environments?
