USB-C Port not connect to external display on HP Laptop 15-dw3000

[wolf1990]

I cannot get my USB-C port to connect to external display. The USB-C port will connect to a phone, but will not connect to USB-C to HDMI adapter or HP Thunderbolt docking station. At first I thought the USB-C port did not support external display, but my co-worker has the same model of computer and docking station with no issue. I can't seem to locate USB-C alt mode, which after researching, is what I need to do. Any suggestions?

There are dozens of machines as shown

They have similar ports

1 SuperSpeed USB Type-C® 5Gbps signaling rate; 2 SuperSpeed USB Type-A 5Gbps signaling rate; 1 HDMI 1.4b; 1 RJ-45; 1 AC smart pin; 1 headphone/microphone combo

As you can see, your machine It ONLY has 1  SuperSpeed USB Type-C® 5Gbps signaling rate port which does NOT support Alt mode nor Power Delivery. You can NOT use it to

• Charge your machine
• Connect to an external monitor with / without hub/dock/adapter
