VGA output not working

[Stepenwulf]

VGA port not working and system does not detect a monitor. However, HDMI port does work. I'm trying to add second monitor. Can this system support two monitors?

What is your Pavilion Desktop 590 ? For example HP Pavilion 590-p0066 machine. Please view the following video

1. Make sure your cables are connected properly to the new monitors. Your PC should automatically detect them and show your desktop.
2. Right-click anywhere on the desktop on any screen and choose Display settings. Scroll down to Multiple Displays, click the drop-down menu and choose a display setting.
3. Choose one of the Duplicate desktop options to show the same things on multiple screens. Pick Extend desktop to extend your work surface.

Regards.

Thank you. I have a HP Pavilion 590 Series Desktop, 8th Gen Intel Core i5-8400,16GB DDR4, 256GB SSD Plus 2TB HDD,2GB AMD Radeon RX 550. 

I should have known this but I'm returning to the PC because of software requirements and forgot much of how to set up a desktop. Because I have a graphics card the internal vga and hdmi will not work. The Radeon RX 550 ports include a hdmi, dvi and display port and after speaking with the seller, can support up to three monitors. Display port to hdmi cable on the way!!
