Solved! Stuck at 60 Hz

[VavrisX]

I recently bought Alienware AW2518HF which is a 240Hz monitor. I connected it to a laptop Lenovo Legion Y520 through HDMI cable 2.0. I did some research and the monitor has HDMI 2.0 port and the laptop has only 1.4 HDMI port. This should allow me to run at least 144 hz. When I try to change the refresh rate in windows or in Nvidia Control Panel it only allow me to put it in 60 Hz. Any ideas?
