Best option for extended display on HP Pavilion desktop

[BillC61]

I purchased 2 HP 27F 4K monitors to use with my recently purchased HP Pavilion Desktop and am unsure what is the best solution to get the highest quality output to my second monitor.  The desktop has 1 HDMI output and 1 VGA output as well as multiple USB ports.  The monitors have 2 HDMI inputs and a display port.  I see that there are adapters for VGA to HDMI and USB to HDMI but unsure as to what would provide the best results.  Any help would be appreciated.

Its specs

It has following ports at its back

• (1) RJ-45 Ethernet port
• (1) HDMI 1.4b/HDCP 2.2 port
• (1) VGA port
• (3) Audio ports (Line-in/Line-out/Microphone)
• (4) USB 2.0 Type-A ports
• (1) Power input port

No way you can connect two 4K monitors to it without an proper video card. For example

It ONLY has 180 W Smart AC power adapter therefore you need  new PSU. One example the RTX-2060 required 500W PSU

Thanks for the detailed information.  I didn't realize it would be that involved.  I had bought a USB C to HDMI adapter and plugged it into the USB C port on the front of my desktop but that didn't work.  Would I be able to use an VGA to HDMI adapter and still get the extended display just not at 4K or will that not work either.  Thanks.
