Have you ever taken a photo or recorded a video of your computer screen, only to find that it looks weird, distorted, or even unrecognizable? You’re not alone. Many people have experienced this issue, and it’s not just a matter of poor camera quality or bad lighting. There are several reasons why computer screens can look weird on camera, and in this article, we’ll explore the main causes and possible solutions.
Understanding the Basics of Computer Screens and Cameras
To understand why computer screens can look weird on camera, we need to delve into the basics of how computer screens and cameras work.
Computer Screens: A Brief Overview
Computer screens, also known as monitors or displays, are made up of millions of tiny pixels that light up to form images. These pixels are arranged in a grid pattern, with each pixel consisting of three sub-pixels: one red, one green, and one blue. When these sub-pixels are combined in different intensities, they create a wide range of colors.
Computer screens use a technology called raster scanning to display images. Raster scanning involves scanning the pixels horizontally and vertically to create a complete image. This process happens rapidly, typically at a rate of 60 times per second.
Cameras: A Brief Overview
Cameras, on the other hand, capture images by recording the light reflected from objects. Digital cameras use a sensor to convert the light into electrical signals, which are then processed and stored as digital images.
Cameras can capture images in various modes, including still photos and videos. When capturing videos, cameras typically use a technique called interlacing, which involves capturing alternate lines of pixels to create a complete image.
The Main Causes of Weird Computer Screens on Camera
Now that we’ve covered the basics of computer screens and cameras, let’s explore the main causes of weird computer screens on camera.
Moire Patterns
One of the most common causes of weird computer screens on camera is moire patterns. Moire patterns occur when the camera’s sensor captures the grid pattern of the computer screen’s pixels, creating a wavy or distorted image.
Moire patterns are more likely to occur when:
- The camera is positioned at a shallow angle to the computer screen.
- The computer screen has a high pixel density.
- The camera’s sensor has a high resolution.
To minimize moire patterns, you can try:
- Positioning the camera at a 90-degree angle to the computer screen.
- Using a camera with a lower resolution sensor.
- Applying a moire-reducing filter to the camera lens.
Rolling Shutter Effect
Another cause of weird computer screens on camera is the rolling shutter effect. The rolling shutter effect occurs when the camera’s sensor captures the image in a scanning motion, rather than all at once. This can create a distorted or wavy image, especially when capturing fast-moving objects or scrolling text.
The rolling shutter effect is more likely to occur when:
- The camera is capturing video or fast-moving objects.
- The computer screen has a high refresh rate.
- The camera’s sensor has a slow readout speed.
To minimize the rolling shutter effect, you can try:
- Using a camera with a global shutter sensor.
- Reducing the computer screen’s refresh rate.
- Applying a rolling shutter correction filter to the camera footage.
Screen Reflections and Glare
Screen reflections and glare can also cause weird computer screens on camera. Screen reflections occur when light from the surrounding environment reflects off the computer screen, creating a distracting or distorted image.
Screen reflections and glare are more likely to occur when:
- The computer screen is positioned near a light source.
- The surrounding environment is brightly lit.
- The computer screen has a glossy finish.
To minimize screen reflections and glare, you can try:
- Positioning the computer screen away from light sources.
- Using a screen protector with a matte finish.
- Applying a glare-reducing filter to the camera lens.
Additional Factors That Can Affect Computer Screens on Camera
In addition to the main causes mentioned above, there are several other factors that can affect how computer screens look on camera.
Screen Resolution and Aspect Ratio
The screen resolution and aspect ratio of the computer screen can affect how it looks on camera. For example, a computer screen with a high resolution and wide aspect ratio may appear distorted or stretched when captured on camera.
Camera Settings and Angles
The camera settings and angles can also affect how the computer screen looks on camera. For example, a camera positioned at a shallow angle or with a wide-angle lens may capture more of the surrounding environment, creating a distorted or unflattering image.
Lighting Conditions
The lighting conditions can also affect how the computer screen looks on camera. For example, a brightly lit environment may create screen reflections and glare, while a dimly lit environment may create a washed-out or underexposed image.
Solutions and Workarounds
If you’re experiencing weird computer screens on camera, there are several solutions and workarounds you can try.
Use a Camera with a High-Quality Sensor
Using a camera with a high-quality sensor can help minimize moire patterns, rolling shutter effect, and other issues. Look for a camera with a high-resolution sensor, fast readout speed, and good low-light performance.
Adjust the Camera Settings
Adjusting the camera settings can also help improve the image quality. Try adjusting the exposure compensation, white balance, and focus settings to optimize the image.
Use a Screen Protector or Filter
Using a screen protector or filter can help minimize screen reflections and glare. Look for a screen protector with a matte finish or a filter that reduces glare and reflections.
Position the Camera Carefully
Positioning the camera carefully can also help improve the image quality. Try positioning the camera at a 90-degree angle to the computer screen, and adjust the camera settings to optimize the image.
Conclusion
In conclusion, weird computer screens on camera can be caused by a variety of factors, including moire patterns, rolling shutter effect, screen reflections, and glare. By understanding the basics of computer screens and cameras, and by trying out the solutions and workarounds mentioned above, you can improve the image quality and capture high-quality photos and videos of your computer screen.

Why do computer screens look weird on camera?
Computer screens can appear weird on camera due to a phenomenon called the “moire effect.” This occurs when the camera’s sensor captures the screen’s pixel pattern, creating an interference pattern that results in a weird, wavy, or distorted image. The moire effect is more noticeable when the camera is close to the screen or when the screen has a high pixel density.
To minimize the moire effect, you can try adjusting the camera’s angle or distance from the screen. You can also use a camera with a higher resolution or a screen with a lower pixel density. Additionally, some cameras have features that can help reduce the moire effect, such as anti-aliasing filters or moire reduction algorithms.
What is the moire effect, and how does it affect computer screens on camera?
The moire effect is an optical phenomenon that occurs when two or more patterns overlap, creating an interference pattern. In the case of computer screens on camera, the moire effect is caused by the overlap of the screen’s pixel pattern and the camera’s sensor pattern. This results in a distorted image that can appear wavy, striped, or discolored.
The moire effect can be more pronounced when the screen has a high refresh rate or when the camera is capturing a video. To reduce the moire effect, you can try reducing the screen’s refresh rate or using a camera with a higher frame rate. You can also use software to remove the moire effect from the captured image or video.
Why do some computer screens look worse on camera than others?
Some computer screens may look worse on camera than others due to differences in their display technology. For example, screens with a high pixel density or a high refresh rate may be more prone to the moire effect. Additionally, screens with a glossy or reflective finish may produce more glare or reflections, which can make them appear worse on camera.
On the other hand, screens with a matte finish or a lower pixel density may produce fewer reflections and less moire effect, making them appear better on camera. You can also consider using a screen with a special coating or filter that reduces glare and reflections.
Can I prevent computer screens from looking weird on camera?
While it’s not possible to completely eliminate the moire effect, there are steps you can take to minimize it. One approach is to adjust the camera’s angle or distance from the screen to reduce the overlap of the pixel patterns.
