Please advice me. I'm triyng to connect monitor to my HP USB-C dock for my HP Elite x3 via HDMI. But there is no pictures output. When I run Continuum app it doesn't see connection. HP Display tools dosn't see connection too. Dock is new one and working fine when I connect some hardware - mice, keyboard. Did this dock doesn't support video output for HP Elite x3 phone? Did I need to buy Cradle dock to my needs? Or do I need to use Dual-Mode DisplayPort cable?
