Scenario

Your desktop computer comes with 3 DisplayPort ports to use in order to connect three computer monitors to them. Thinking that the setup is straight forward, you purchase three DisplayPort cables. After plugging each DisplayPort cable into their respective locations and turning on your computer you notice that two monitors are active and the third one is blank.

On your computer, you head over to your display options panel and try extending your desktop to the third monitor, only to find out that it still does not work.

Solution

You will still be able to use all three DisplayPort ports on your computer, you first have to see what available ports you have on your computer monitor. You should have any of the following ports: DisplayPort, HDMI, DVI, and or VGA port.

If your computer monitor does not have a DisplayPort, you will have to purchase a DisplayPort to DVI or VGA or HDMI Adapter. On your computer monitors, you can only use two of the same ports at the same time. Example below:

Monitor 1 (DVI Port / VGA Port )
– Use DisplayPort to DVI Cable

Monitor 2 (DVI Port / VGA Port )
– Use DisplayPort to DVI Cable

Monitor 3 (DVI Port / VGA Port )
– Use DisplayPort to VGA Cable

Alternatively, if your computer monitor only has a HDMI port and a DisplayPort, you will have to purchase two DisplayPort to HDMI adapters and one DisplayPort (Male to Male) cable.
