Monitor is not working with DisplayPort to HDMI adapter

I have a HP EliteDisplay E222 and it is not able to recieve signals using a HDMI to DisplayPort adapter. I have tried plugging in the DisplayPort side of the adapter into my computer and into my graphics card and both of them give me no signal and that makes
me think it is the monitors issue. However, when I plug the current monitor I am using into the HDMI side of the adapter (when the DisplayPort side of the adapter is connected to my computer) I also get no signal.

I have confirmed that the adapter works on my other computer but I just can not find out why it is not working on my main one.

I have tried:

1. Letting windows pick graphic card drivers (RX 570)
2. Installing the latest drivers
3. Taking the power cable out of my second monitor for one minute
4. Resetting the monitor
5. Turning off the power saving setting in the monitor
6. Turning power mode to high performance in Windows 10

Unfortunately my current monitor has no DisplayPort port. If it did, I could of connected the DisplayPort side of the adapter to it to determine if the graphic card is the problem or if the monitor is.

 

Monitor Recommendation for Dual Monitor with Displayport, HDMI, DVI

To go from HDMI on computer to DisplayPort on monitor, you need a powered adapter such as this:
Amazon.com: HDMI to DisplayPort Converter Adapter Cable with USB Power,QGeeM 4K x 2K HDMI to DP Adaptor for HDMI Equipped Systems,Compliant with VESA Dual-Mode DisplayPort 1.2, HDMI 1.4 and HDCP: Electronics

The USB-C on your XPS 15 9550 is the DisplayPort. If you want dual external monitors on the XPS 15 9550, the best combination is 1 monitor with HDMI and one monitor with DisplayPort. The HDMI monitor gets connected to the HDMI port on the computer with a simple HDMI cable. The DisplayPort monitor gets connected to the USB-C port on the computer with a USB-C to DisplayPort cable:

If you have two external monitors with HDMI, then one goes HDMI to HDMI with the simple cable, and the other goes to the USB-C port on the computer with either a USB-C to HDMI adapter, or USB-C to HDMI cable:

Amazon.com: USB C to HDMI, CableCreation USB 3.1 Type C to HDMI 4K Hub Adapter (Thunderbolt 3), DP Alt Mode, Male to Female, Compatible MacBook Pro/Chromebook Pixel/Dell XPS 13/Yoga 920/Samsung Note S9,S8, White: Electronics

The only difficult connection would be to connect a DisplayPort monitor to the HDMI connection on the computer, you don't want to do that.
