my 3rd display won't connect

[QuattroOMG]

Hello, i just bought my self a third monitor, i have one BenQ XL2720Z and 2 BenQ RL2455HM. I've always used 2 monitors but i decided to go for 3 monitors because my graphics card can handle it, and i like it to game on 3 displays. My graphics card is the AMD Radeon R9-255/2G with a DVI, DP & HDMI port i bought a DP to HDMI cable and put that one in my main monitor the BenQ XL2720Z. I use the DVI to DVI and HDMI to HDMI on my other 2 BenQ RL2455HM Monitors but one can connect while the other goes stand bye. What can i do!? i alrady re installed all my drivers etc. and in Eyefinity my 3rd display wont show up either. sorry for my bad english..

Hi,
"i bought a DP to HDMI cable'

Try with an active adapter like https://www.amazon.com/Cable-Matters-DisplayPort-Supporting-Technology/dp/B00EDT0072
