I have an HP ProBook 4740s and just bought a Samsung SD300 LED monitor for an extended display.
As soon as I plug the cable into my laptop (even with the monitor's power off), my laptop display goes black. The extended screen does not show my laptop screen info at all - so I have to unplug the cable to be able to do anything.
Severly frustrated! I have installed the driver provided on the DVD which came with the monitor.
Both Display adaptors are on the most updated drivers.
Please assist
Thank you
