Optiplex 7050 MicroForm Factor Unable to Detect th Monitor

I had recently purchased this computer for the purpose of running three monitors. Upon booting for the first time, all three monitors showed that they detected input. However, upon that first boot, it got stuck in an infinite boot cycle. After several hours of troubleshooting with Dell Support, we were able to get it up and running by reinstalling windows. This is where the problem began. The DP on the motherboard and the DP that we had added to it while ordering both work, it is the HDMI on the motherboard that is not giving any output. We have tried a number of different cables and monitors and they were all unable to be detected in display settings. We have also tried updating the graphics drivers. I have come here in hopes to get this figured out. Thanks in advance for any ideas or help that you are able to provide!
