3 displays don't work on graphics card

[krooyakkersanutookarieskkru]

My graphics card has VGA dvi and HDMI. I have them all plugged in but will only let me display two at a time. Windows shows all 3 but it forces me to set one as do not use this display. Is there any way to use all three at the same time.
