Waarom ziet alles op mijn scherm er wazig/korrelig uit?
The display resolution that is configured may not be the correct one for your screen. To solve this:
Go to the desktop and start typing Settings.
Klik op Schermen om het paneel te openen.
Probeer een aantal van de Resolutie-opties en selecteer die die het scherm er beter laten uitzien.

If you have two displays connected to the computer (for example, a normal monitor and a projector), the displays might have different optimal, or native, resolutions.
Using Mirror mode, you can display the same thing on two screens. Both screens use the same resolution, which may not match the native resolution of either screen, so the sharpness of the image may suffer on both screens.
Using Join Displays mode, the resolution of each screen can be set independently, so they can both be set to their native resolution.
