How do I display the same content on multiple screens?

When all screens are detected, you can choose how Windows uses them. If you want to duplicate the screens and have the same image on both, make sure 'Duplicate these displays' is selected in the Multiple displays drop-down menu. It's much the same in both Windows 8 and 10.

How do you compare screens?

Look at the resolution offered by the LCD monitor.

The resolution number refers to the highest number of pixels the monitor can display. The higher the resolution number, the better quality picture you'll have on the computer monitor. A monitor should also be able to display different resolutions.

Adjust the monitor height so that the top of the screen is at—or slightly below—eye level. Your eyes should look slightly downward when viewing the middle of the screen. Position the monitor at least 20 inches (51 cm) from your eyes—about an arm's length distance. If your screen is larger, add more viewing distance.
