FAQ:
What is LCD?
LCD stands for Liquid Crystal Display, which is a flat panel display technology commonly used in televisions, computer monitors, and mobile devices.
How does the LCD work?
LCD works by using liquid crystals that are sensitive to electric charges to display images on a screen. A backlight is used to illuminate the screen.
How to test a laptop LCD screen?
If you are experiencing issues with your laptop LCD screen, you can use this tool to test its performance and identify any potential problems.
To test your laptop LCD screen, simply navigate to the tool and click on the separated color buttons. The tool will then display the selected color at fullscreen mode.
If you notice any abnormalities or defects during the test, it may indicate that your screen is damaged or malfunctioning. In this case, you may need to contact a professional repair service or replace the screen altogether.
How does the tool on your website detect the real screen resolution of a device?
This tool detects the real screen resolution of a device by taking into account the device's pixel density. It multiplies the reported screen resolution by the device's pixel density to provide a more accurate representation of the resolution.
Why is it important to optimize a website for the viewport size of a user's device?
Optimizing a website for the viewport size of a user's device is important because it ensures that the website looks great and is easy to use on any screen size. This is particularly important for responsive website design that adapts to different screen sizes on desktop and mobile devices.

By using our tool, they can ensure that their website is optimized for the real screen resolution and viewport size of their users' devices.
What is viewport size?
Viewport size refers to the visible area of a web page in a browser window or device screen. It's determined by the size of the browser window or device screen minus any space taken up by the browser's user interface elements like the address bar, tabs, and toolbar. The viewport size can vary depending on the device and browser being used. As viewport size can impact how a website is displayed on different devices and browsers, developers use responsive design techniques to adapt layouts to different screen sizes and resolutions. By using flexible layouts and media queries, developers can create websites that look good and are easy to use across different viewport sizes.
What is native screen resolution?
Native screen resolution refers to the physical number of pixels on a display screen. It is the maximum number of pixels that can be displayed on the screen and is determined by the hardware itself. For example, a display screen with a native resolution of 1920 x 1080 can display a maximum of 1920 pixels horizontally and 1080 pixels vertically. This resolution is also known as the "optimal resolution" and is typically the highest resolution that a screen can display. When a screen displays an image or video at its native resolution, the image will look the sharpest and most detailed. However, if an image or video is displayed at a lower resolution, it may appear blurry or pixelated. Native screen resolution is an important consideration for anyone working with digital media, such as photographers, graphic designers, and video editors.
What are the differences between LCD and OLED display?
| LCD | OLED |
|---|---|
| Technology: Uses liquid crystals with a backlight. | Technology: Uses organic compounds that emit light individually. |
| Image Quality: Good color accuracy and brightness but limited black levels and viewing angles. | Image Quality: Superior contrast and true blacks with excellent viewing angles. |
| Power Consumption: Consumes more power due to a constant backlight. | Power Consumption: More power-efficient, especially with darker content. |
| Durability and Lifespan: Longer lifespan and resistant to burn-in. | Durability and Lifespan: Prone to burn-in and has a shorter lifespan. |
| Flexibility: Rigid and not suitable for flexible displays. | Flexibility: Can be made flexible and used in innovative designs. |
| Cost: Less expensive to manufacture and buy. | Cost: More expensive due to complex manufacturing. |
