Lenovo T400 Dual Display Issue
A very quick one for those with a lenovo t400 laptop . there is a very common problem when using multiple displays with a docking station on the t400 where only the vga port will display a video signal.
3 Easy steps
1. Check your power manager settings , when you are running in battery saving mode the switchable graphics will be unavailable and you will not see any signal on your 2nd machine.
2. Run lenovo update to get the most recent video card drivers
3. Check Source on Monitor , and display options with FN + F7
