Using the Thunderbolt Port for Display Only
1. Restart the computer.
2. Enter the Aptio Setup Utility (BIOS) by pressing F2 at startup.
3. Use the arrow keys to select the Advanced menu.
4. Select Intel(R) Thunderbolt and press Enter.
5. Select Intel(R) Thunderbolt Technology, press Enter and select Enabled.
6. Select Security Level and press Enter.
7. Select DP++ only from the menu and press Enter.
8. Press F4 to save the change and restart the computer.
Setting the port to "DP++ only" will only allow display devices to connect to the port, and no data connec-
tions will be allowed. If you want to use the Thunderbolt port for display only then you must set this
as the security level, and DisplayPort 2 will then be turned off.
Ejecting Thunderbolt Devices
In order to prevent system problems make sure you do not simply pull the cable out from the Thunderbolt
port. The hardware must be ejected safely:
1. Go to the notification area of the taskbar and click on the Safely Remove Hardware and Eject Media
icon.
2. Click on Eject "Thunderbolt Device Name".
3. When you see the "Safe to Remove Hardware" message you can remove the cable.
