My laptop is the following: HP Spectre x360 Convertible 13-ae092TU
Specs can be found here: https://support.hp.com/gb-en/document/c05966629
I've looked on OzBargain, eBay, and Amazon but keep reading the same mixed reviews of "some work with some laptops but not others". Where I'm stuck is finding one that will definitely work and is not too expensive. Can anyone help?
Your USB-C needs to support DisplayPort alt mode, looking at the specs below your safe as it supports DP1.2
External ports: 2 Thunderbolt™ 3 (Data Transfer up to 40 Gb/s, Power Delivery, DP1.2, HP Sleep and Charge); 1 USB 3.1 Gen 1 (HP Sleep and Charge); 1 headphone/microphone combo
