Cannot Connect Dual monitors to OptiPlex 9020 Mini-Tower
I'm not super well-versed in computer hardware, but here is my issue.
Two Dell monitors were displaying correctly on OptiPlex 9020 Mini-Tower. The Mini-Tower has 3 DP interfaces, 1 VGA, and 1 DVI. Each monitor had 1 VGA port and 1 DVI port. One monitor was plugged into the DP interface on the Mini-tower with a DVI cable that used a DVI to DisplayPort adapter. The second monitor was plugged in using a DVI cable.
I'm switching these older monitors with two E2216H monitors, where each monitor has 1 VGA port and 1 DP. The only way either monitor will display is if it is plugged into one particular DP interface on the Mini-Tower (the same DP interface that the previous monitor used). Neither monitor will be recognized if plugged into the other two DP interfaces. Instead I get the message "Entering Power Save Mode". Right now I have one E2216H monitor plugged into that DP interface and it's displaying well. I've tried connecting the second monitor into the VGA interface and the DVI interface (using both a DP and a VGA adapter). Unfortunately, I keep getting the "Entering Power Save Mode" message.
Hopefully I gave enough information. Any help is appreciated. Thank you.

Models like the 9020 have a much easier way.
You download the cab file for your version of windows.
Then you unzip the cab file with 7zip
https://www.7-zip.org/download.html
Then you copy the extracted folder to the My Documents library
Then right click on the video in device manager and say UPDATE From my machine instead of update from the internet.
You do that for any missing drivers as well as overall saying scan for hardware changes.

2 monitors is not possible when you are using the default VGA driver.
You must have the INTEL GRAPHICS Driver to support more than 1 monitor.

Can I update the driver I have now to the driver that I need? Would I go to support.dell.com to scan for updates?

The microsoft display adapter driver does not support dual monitors.
You need the driver for your specific model.
