# Screen Resolution

**Shows, how many pixels can be displayed on the screen in total. These are so-called "CSS pixels", that were specifically introduced for web developers.**

- A rounding in steps of 10 is done.
- *"unknown"* includes accesses, for which no screen resolution could be determined.

> If you have adapted the scaling at your operation system's settings, this also has influence on the Screen Resolution shown as a result.

#### Example

The chosen screen resolution is 3840x2160. If a scaling of 200% is chosen, the screen resolution is shown as 1920x1080.

#### Procedure for determining the screen resolution

- For desktop devices:
  - The information about the screen resolution is submitted via the tracking pixel.
  - If the pixel can't read the screen resolution, the value *"unknown"* is submitted.
- For mobile devices (mobile phones and tablets):
  - If the tracking pixel submits the screen resolution of the device, this value is used.
  - If the tracking pixel doesn't submit the screen resolution of the device:
    - Mapp maintains for Intelligence an internal database with known screen resolutions of mobile devices (e.g. Samsung Galaxy S8 -> screen resolution is 2,960 x 1,440 px). If the mobile device and its screen resolution is listed there, this value is used for the screen resolution.
    - If the mobile device and its screen resolution is not listed in the database:
      - In some cases the screen resolution can be determined based on the operating system (e.g. some old versions of iOS only run on devices with a specific resolution).
      - If the screen resolution still can't be determined by this procedure, the value *"unknown"* is depicted.
