hi , just bought a MSI N210 PCI-E VGA card, plugged it into the PCI-E x16 Gen2.0/3.0 slot of my Asus P8B75-M LX Plus motherboard. connect all the cables ( VGA cable connect to the MSI card ) , power on the PC and ...... Presto !!! ..... nothing came on the monitor. plug VGA cable back to onboard port , display came out; figuring it might be the BIOS settings , i rebooted into BIOS, but unable to find the setting to turn off onboard display .... any ideas ?
