A foreign object, such as a paper

The Built-in Display has
bright or dark spots.

this is normal for a large display.
This is normal; do nothing.

enough to interfere with your
operation needs.

but have less resolution by changing your display
compression setting, (See Display Device submenu,
located under the Startup menu of the BIOS. (See
