Am I able to add another HDMI port to my HP Desktop M01-F0014

Am I able to add another HDMI port to my HP Desktop M01-F0014? 

I am trying to hook-up 3 monitors. I currently have 2 (one by VGA and the other by HDMI). I tried a USB to HDMI adapter for the third monitor but had no luck. My next though was to see if I was able to add another HDMI port but am unclear about which kind best suits my current hardware

@RossW2 -- is this your computer: HP Desktop - M01-F0014 Product Specifications | HP® Customer Support

That web-page states:

Graphics -- Integrated AMD Radeon™ Vega 3 Graphics
Expansion Slots - 1 PCIe x1; 1 PCIe x16; 2 M.2

So, you could add a graphics adapter card into the PCIe x16 socket.

Select a card that has multiple HDMI-output sockets.

I am not sure whether adding such a card will cause the motherboard to automatically disable the integrated graphics, but I suspect that this will happen.

I see nothing in the specifications for a USB-C socket, which you would need to connect to a monitor, via a USB-C-to-HDMI cable.

Maybe, if you add-in a graphics adapter card, it will have a DisplayPort adapter:

card --> DisplayPort cable -> DisplayPort input on monitor #1 -->  DisplayPort output on monitor #1  --> DisplayPort input on monitor #2 -->  DisplayPort output on monitor #2 --> DisplayPort input on monitor #3

Note that not all DisplayPort monitors have BOTH input and output ports for "daisy-chaining".

In your case, monitor #3 does not need an output port.
