Dear HP community,

@kratosx94 Here's the information about your device's USB ports:

2 USB 3.1 Type-C™ Gen 1 (Data Transfer up to 5 Gb/s, Power Delivery, DP1.2, HP Sleep and Charge); 2 USB 3.1 Gen 1 (1 HP Sleep and Charge); 1 headphone/microphone combo

As mentioned above, you only have 2 USB 3.1 ports that support display conversion via DP 1.2 Alt mode, if connected to any of the other USB 3.1 ports, the HDMI may not work, so please check the other ports and keep me posted.

Also, click here for details on how USB Type-C ports work.
And check with another adapter (USB to HDMI)

Hey there, thanks for your reply, the problem is already solved, i bought another USB C TO HDMI and it worked. I believe the old USB C TO HDMI was not comptable with my Laptop.
