How to find out your screen resolution?

A screen's resolution determines its display quality, based on the number of pixels it can display. It is essential for choosing a screen adapted to your needs, or for optimizing your visual parameters. Here's how to easily identify this information.

Understanding screen resolution

Resolution corresponds to the number of pixels displayed in width and height. For example, a resolution of 1920x1080 means that the screen displays 1920 pixels in width and 1080 in height. The most common resolutions are :

• HD (1366x768): Standard quality for basic screens.
• Full HD (1920x1080): Popular resolution for good image quality.
• 4K (3840x2160): For ultra-detailed display, ideal for professionals or gaming.

Check your computer settings

You can check your screen resolution directly from the operating system.

Windows :

1. Right-click on the desktop and select "Display Settings".
2. Under "Screen Resolution", you'll see the resolution currently in use, as well as the options available.

MacOS:

1. Click on the Apple icon, then on "System Preferences".
2. Go to "Monitors" and consult the "Resolution" tab.

Consult the documentation for your monitor or computer

If you still have the user manual or original packaging, the screen resolution is usually indicated. This is particularly useful for external monitors or laptops.

Search online by screen model

If you know the model of your monitor (e.g. Samsung LC27R500), do an online search. The technical specifications available on the manufacturer's website or on retailers' product sheets always mention the screen's native resolution.

Why is resolution important?

• For visual comfort: the right resolution guarantees better image quality, especially for professionals and gamers.
• For performance: A high-resolution display requires a high-performance graphics card.
• For compatibility: When buying a new screen or cable (HDMI, DisplayPort), knowing the resolution will help avoid incompatibilities.

To sum up, identifying your screen's resolution is a simple but crucial step towards optimal viewing and a pleasant visual experience.
