USB-C to HDMI not working?
I used to have a 3 monitor set up with an iMac, however, I have upgraded and build my own PC.
here are the specs:
Motherboard: ASUS Prime Z490-A
CPU: Intel i7 10700K
Monitors: 2 AOC 27B1H 27" LCD Monitors
1 MSI - Optix 27" LED Curved FHD FreeSync Monitor
I believe that is all the information needed to understand what's going on, I hope.
My main monitor, the MSI Optix, is connected via a Display port to HDMI adapter, Display Port connected to the motherboard, HDMI connected to the monitor, works fine.
my left monitor is connected to the HDMI on the motherboard, works fine.
However, for my right monitor...
At the time, due to the obnoxious prices of Graphics Cards at the moment, I am going to hold off for a while, so I have to work with the motherboard for now. I bought a USB-C to HDMI wire (j5create USB-C to 4K HDMI Cable) plugged it into the USB-C port and... nothing.
I tried drivers, plugging in and un-plugging, turning on and off, updates, nothing.
Should I try a USB 3.0 to HDMI instead to see if that works?

Macs with USB-C also have a "thunderbolt" interface sharing the connector and that can link to a display.
A standard non-thunderbolt USB-C port won't work with the same adapter.
A USB3 to HDMI unit should work OK; just make sure it's not one that is dedicated to a specific make or model of PC, rather than a universal one.

Macs used that TYPE of interface to do other connections, but that doesn't mean video will work, it is just not fed through the usb port on windows.
Yes, you will need a dual port video card to get it to work.

hate to break it to you, but USB is just a connection type. it will not output video unless the device is designed to do so.
in this case, the motherboard would need drivers for this. most motherboards do not do this. sorry.
just because a cable exists doesn't mean it will convert a signal by itself. only an ACTIVE cable converts a signal inline, and these usually require plugged in to a power source...
