I have two Dell Latitude d520 laptops one is working on a projector and one is not. The one that is not not working on the projector works on lcd monitor just not the projector. Any ideas what might cause this? All the settings look the same , unless there's something i'm not seeing.
ive tired :
-> updating bios
-> updating video card drivers
-> reghosting the pc
-> booting up without start up items
-> there is no dell quickset installed
-> checked power settings (by comparing laptops)
-> just out curosity could it be the distance between the laptop and projector?
-> can the same model of laptop give out different power?
