Understanding Your Display: What Is Screen Resolution?
When you ask, "what is my screen resolution," you are asking for the exact number of distinct pixels in each dimension that can be displayed on your current device. It is usually quoted as width × height, with the units in pixels: for example, 1920 × 1080 means the width is 1920 pixels and the height is 1080 pixels.

Display Resolution vs Browser Viewport
Many users looking to check their display device get confused between their display resolution and their browser viewport. Here is the difference:
- Display Resolution (Device Resolution): This is the absolute maximum number of physical pixels on your hardware monitor.
- Browser Viewport: This is the size of the actual usable content area inside your web browser.
