Problems with external display

I recently bought a new MacBook Pro (16-inch, 2019) and have since had issues with my external display. The display keeps disconnecting randomly and mostly I end up reconnecting the cable frequently. I have noticed that often the connection gets lost when I plug something into one of the other USB-C ports on my MacBook and sometimes just randomly. Is this a problem related to the display or my MacBook?

I have tried to use both USB-C to HDMI and USB-C to DisplayPort.

Also I have tried resetting NVRAM on my MacBook and the problem remained.

I looked for a driver from HP's website but it doesn't exist for Mac.

Have any of you had similar issues with an external display? Is there any solution?

Have you tried connecting the monitor to a different USB-C port especially on the other side of the laptop?

Is anything else plugged into the dongle used for the monitor? If so, then disconnect those items from the dongle.

Is anything plugged into the monitor? If so, disconnect them from the monitor.

Try an SMC reset.

Do you have another external display you can test with? Maybe a TV?

Hey, I tried USB-C ports on each side of my computer. The monitor is connected directly with a cable and not via any dongle. There was no problem like this with my old display. I have tried SMC reset now and will see if it helps.

Are these good quality display cables which can support a 4K display?

What type of devices are being plugged into the laptop that cause the display to go out? Does this happen if the devices are being attached to the USB-C ports on the other side from the monitor?

I don't have a lot of experience with USB-C connected displays. I do know that a lot of monitors tend to have some weird idiosyncrasies in general. Have you tried contacting HP for support or checking the HP website for documentation and FAQs about this monitor?
