Windows 10: Why does my second monitor keep going in and out when I plug in my displayport?

When ever I plug my DisplayPort in my monitor shows picture then it doesn’t. It’s only with display port and I have tired multiple different cables and the issue still persists. It only happens when I plug in another monitor. Any idea how to fix please let me know because this driving me crazy! This only started recently.

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.

Windows 10 does not recognise second monitor

Hi Raffaele,

For us to sort out this problem with your dual monitors, we'd like to gather more information about what happened so we can address the issue appropriately. Below are a few questions we'd like to ask:

• Does the monitor on the laptop work if you disconnect the other monitor?
• Is the second monitor connected to the laptop using a DVI, HDMI, or DisplayPort cable?

While waiting for your feedback, we suggest that you disconnect the second monitor from the laptop and check if its own monitor is working. If not, restart the laptop and check again.

Update us with the result.

Regards.
