Ideapad 500 15ISK external monitor low resolution

[tumaninalex]

I tried to plug in a BENQ monitor with native resolution 2560x1440, but I can choose only 1920x1080. I tried VGA port and HDMI port, no matter. The specification of Intel HD 520 says, I can set 4K.

Solved by buying another HDMI Cable. The old one was perhaps lower than 1.3
