DEDICATED VIDEO CARD

If your PC has a dedicated video card this will be located in an expansion slot on the PC as shown in the image to the left . 

Many motherboards will have the same or similar connections on their back panel however these are disabled when you install a dedicated video card.

Motherboards may have a VGA 15 Pin Blue connection and this may not be on the dedicated video card . Connecting a VGA monitor to the connection on the motherboard will not work. If your monitor only supports VGA you will need either an adapter or cable to connect the VGA monitor . 

If you order a dedicated video card ( NVIDIA or RADEON ) you should make sure your monitor has either DVI , HDMI , Mini HDMI or Display Port Adapters. Older monitors and entry level monitors will today still only have VGA and will require an adapter or cable which is not supplied with the PC or with the monitor.

IMPORTANT
Once a dedicated video card in installed in a PC the video output connections on the motherboard are disabled . You will not be able to get a signal and will see an error such as NO SIGNAL on your monitor.
