Display provides you with the ability to modify display orientation, brightness or contrast of a display device as well as turn your monitors on/off via the command-line.

It is meant to be a small footprint option for controlling various display aspects on supported display devices with an emphasis on power saving.

Display features many parameters for example:

To turn all the monitors off, you would use, display32 /power off, or to rotate the display orientation of monitor #2 by 90° counter-clockwise, display32 /device 2 /rotate 90.

If Display is used in a batch file, you can use ERRORLEVEL to check the completion code returned by the program. The possible return codes are listed in the table below.

0 - Success.

1 - Syntax error or help/registration information displayed.

2 - General failure.

3 - Unable to adjust brightness.

4 - Unable to adjust contrast.

5 - Unable to set display orientation or position.
