Press <Fn> and the up-arrow key to increase brightness on the integrated
display only (not on an external monitor).
Press <Fn> and the down-arrow key to decrease brightness on the
integrated display only (not on an external monitor).

Making Images and Text Look Bigger or Sharper

NOTE: If you change the display resolution from the current settings, the image
may appear blurry or text may be hard to read if you change the resolution to one
not supported by your computer and display. Before you change any of the display
settings, make a note of the current settings so you can change back to the
previous settings if you need to.
You can enhance the legibility of text and change the appearance of images
on the screen by adjusting display resolution. As you increase resolution,
items appear smaller on the screen. In contrast, lower resolution causes text
and images to appear larger and can benefit people with vision impairments.
To display a program at a specific resolution, both the video card and the
display must support the program, and the necessary video drivers must be
installed.
NOTE: Use only the Dell-installed video drivers, which are designed to offer the
best performance with your Dell-installed operating system.
If you choose a resolution or color palette that is higher than the display
supports, the settings adjust automatically to the closest supported values.
To set the display resolution and refresh rate for your display, perform the
steps.
