Question Need help with hooking up 4 monitors please

[Open_Philosopher]

I have 4 monitors,

• 240Hz Alienware AW2518H on Displayport
• 240Hz Alienware AW2518HF on Displayport
• 240Hz Alienware AW2518HF on Displayport
• 120Hz Alienware AW3418DW on HDMI

I’m using these on a GTX 1080Ti which only has 3 Displayports and 1 HDMI. The problem is that I don’t know which cable to use in order to get the full 120Hz on the 4th monitor since HDMI can't.
It's my first time adding in 4 monitors and didn't realize cables played an important part too.
If anyone could help me with this issue I’d be grateful, thanks.
