To connect a standard VGA monitor directly to the module's VGA output use connector J77A on COM Express®
miniBaseboard Type 2 or use a DVItoVGA Adapter to access the available VGA connection on DVI-I connector J8 on
ETXexpress® miniBaseboard. The DVI output is available through a Silicon Image SiL1364/A SDVO_B to single link DVI
PanelLink Transmitter
The default jumper configuration for J12 and J13 on ETXexpress® miniBaseboard enables DVI DDC Data usage with 5V
bus level voltage. To enable VGA I2C connection short pin 1 and 2 of J12 and J13. To change voltage level on DDC I2C

Note1: The default display configuration in the BIOS Display settings for most Kontron ETXexpress modules is set to
"CRT and LVDS". To use a DVI monitor directly the BIOS Display settings may be changed to "SDVO only" or
"CRT and SDVO". Newer BIOS revisions enable SDVO output automatically if no LVDS device is present.
Note2 It's strongly recommended to use a VGA monitor or LVDS display during Windows OS installation. Windows
may disable the SDVO output during installation.
Note3: The Intel® GMA driver may disable the SDVO output on platforms with Intel® chipsets. Press the default GMA
driver hotkey "CTRL+ALT+F4" when the reboot after driver installation has finished to enable Digital Display.
