Monitor is not migrated and changes brightness

[mackan73]

In the device manager the display shows the following event:

Device DISPLAY\HPN3616\7&235a3a51&a&UID260 was not migrated due to partial or ambiguous match.

I have the drivers HP Pavilion 27 Quantum Dot Display installed.

Have noticed some issues, among other things the brightness is changed now and then, and some strange colors if changing color settings on monitor. 

I have changed graphic card freom AMD RX480 to AMD RX5700XT, but got the same issue for both the old and the new one.

Also replaced the HDMI cable (included with the monitor) to a DisplayPort cable.

@mackan73  If you've connected an alternate monitor to your device and checked if that worked fine and the brightness doesn't change on its own, this could be a hardware malfunction,

And I suggest you reset the monitor to factory defaults using the below steps to resolve the issue:

Use the OSD menu to adjust the monitor screen image based on your preferences. You can access and make adjustments in the OSD menu using the OSD joystick on the monitor's rear panel.

To access the OSD menu and make adjustments, do the following:
1. If the monitor is not already on, press the power button to turn on the monitor.
2. To access the OSD menu, press the center of the OSD joystick.
3. Move the joystick up, down, left, or right to navigate menu choices. Press the center of the joystick to make a selection.

4. Check for brightness settings & if everything is set to manual, use the factory reset under management.

Yesterday, I did reset the monitor to factory default but it is still changing brightness now and then. I have tried factory reset a couple of times before.

A few weeks ago I brought my PC to my brother and used one of his monitors (Samsung), and did not have this issue then. Also, everyhting worked fine with my old monitor (Benq). But, both my brothers and my old monitor has no support for 2k resolution, HDR and freesynk.

Fill the web-form, to populate a case number and phone number for yourself!

Also, if you are having trouble navigating through the above options, it's most likely because the device is out of warranty, if yes? please send me a private message with the region you are contacting us from,

On the Swedish site, there s no sign-in and web-form on the contact page, unless you have a business.

For persons, there are only a virtual assistant and a FAQ.

There are links to agents, but only for laptops, destops, printers etc, i.e. not for monitors.

@mackan73 In that case, I suggest you contact the local authorized service center for HP and they should be able to help you out.

Got an answer from my  local authorized service center for HP today.

They say they cannot help me out with monitor issues. Only PC and tablets...
