Selecting Screen Resolution 

4-1

4 Selecting Screen Resolution

Refer to your monitor documentation for its supported resolutions. If your 
monitor complies with automatic detection (DDC or display data channel), 
your monitor automatically uses the highest resolution and refresh rate that 
fits in the available frame buffer. If you want to select another resolution or 
refresh rate, use these instructions.

If your monitor does not comply with automatic detection, when you first 
turn the 

NC

 on, the display uses a default resolution that depends on the 

installed video cable and monitor capabilities. Your monitor might not 
support this setting or this setting might not provide the highest resolution 
and refresh rate that your monitor supports. 

The Boot Monitor provides a menu that selects the correct resolution and 
changes the dpi (dots per inch) setting for the monitor. 

Caution

If you are using third-party monitors, you might damage your monitor by selecting 
the wrong screen resolution. Make sure your monitor supports your selection. 

If you are using NCD monitors, you will get a blank screen if you select a screen 
resolution that is outside the range of your monitor. 

To change the resolution:

1. Turn on the system or reboot (if the system is already on).
2. After the Boot Monitor title and version number, messages similar to the 

following appear. Press the Escape key to interrupt the booting process 
and access the Boot Monitor prompt (>).
