I have have a HP Elitebook 8470p, when i use the displayport with an adapter for DVI, the monitor, a Pavillon 22bw shows "Monitor going to sleep". How can I fix that? PD: The VGA connection works fine
Verify that the settings on the monitor is either scanning for active port or is set for the DVI port. Today's monitors with multiple input ports require setting changes just like PCs.
