USB to HDMI not working


Thread Starter

Hi! I don't understand why, but my USB to HDMI cable isn't working.

I bought it from Amazon and in the description it said that it didn't need a drivers being installed.
Also, I think this is the problem but I'm unsure, it's classed in my device manager in "audio inputs and outputs" as Digital Audio Interface (3 - USB Audio). I don't know why it is in that section or how to move it out but that's one of my biggest issues.

I'm using the cable as I don't have a spare HDMI port in my PC - I'm using it for a third monitor. It's very annoying that it won't work, does anyone know how I could fix it?

Hi and welcome to TSG,

Can you post a link to Amazon showing the exact cable you bought please ?
