Boot Display Device 

This option is used to set the boot display device. CRT1 represents the VGA on-board while 

LVDS and DVI are the display connectors on the external graphics card.   

Note: when choosing LVDS or DVI, please make sure the graphics devices 

supplied by EVOC have been installed on the motherboard; otherwise, there would 

be no display when booting or it is unable to boot.   

 

Flat Panel Type 

This option is used to set the resolution for the LVDS screens in use, including 

18-bit, 24-bit, single-channel and dual-channel, etc. Only when the LVDS graphics 

card supplied by EVOC is used and the Boot Display Device option is set to 

LVDS, is this option available.
