PanelLink Transmitter

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.
