Support Article - Two monitors- how to add

You should be able to use two monitors with your new PC if you have a graphics card.

Please make sure that the primary monitor is connected to your gaming  graphics card via HDMI, DP (Display Port) or DVI (Digital Video)

You can then use one of the other 3 ports to connect another monitor

Some of the very high end GPU's only come with HDMI & 2 DP

On some of the very high end gaming cards you can also connect a 3rd monitor however you will get much lower frame rates in games because you have effectively tripled the amount of work your GPU needs to do. 

Also  if you wish you can also connect a further monitor to the connection on the motherboard however this will only be suitable for simple games or as a extra subsidiary display 

If you bought a PC without a graphics card then please connect your cable to the motherboard, you will only be able to use one monitor.
