Using a StarTech.com switch (SV231DPDDUA), the secondary monitor does
not turn on.
Both DELL TFT-s are with displayport connected to the StarTech.com
switch.
The computers have 2 displayport outputs. 4 displayports go into the
switch to switch 2 monitors at once.
If computer boots up, it does not recognize the second monitor. The second
monitor is recognized under
windows, but it cannot be turned on: driver failure.
