Need to unlock my S5 with a broken LCD but it's pin locked

A

AC Question

The phone still works fine but the LCD is completely dead. My computer recognises it and it goes on makes noises etc.

I just need to figure out a way to unlock it. I've had a look online and my best bet looks to be to use an MHL to HDMI adapter with a USB and then use a mouse to unlock it. But I need some help really need the photos and videos from the phone
