Thank you for contacting us.
Before starting, please uninstall manually all the graphic drivers (OEM and Intel®) from device manager. Once that you delete them and the basic display driver is exposed, please reboot the computer and check again device manager to make sure that you got rid of them. Please do it while you have no internet access.
Since you own OEM Motherboard, the first thing to do will be updating the OEM customized drivers for your machine, found here:
You will need to look for the Intel HD Graphics 510 / 530 / 630 Driver released back in 27 Apr 2018, located as the second option from the bottom up.
If that does not give you positive results, please uninstall them again following the same exact process and then go ahead and perform a manual installation of the drivers by following the instructions on this video:

None of the OEM drivers or the latest Intel driver for that matter works for me. I have just verified it. They all give the same result. The display ends up showing 6-bit and poor color reproduction. I even downloaded the latest A07 driver CAB from here which contains an older driver from 2017. This does not work either.
What works is Microsofts default driver but it does not provide audio via DisplayPort. I have now reverted back to Dell's Precision 5520 OEM driver version 184.108.40.20664. This works as intended all though the driver is a bit old.
My issue is resolved with this workaround but obviously it would be nice to have an update driver from this year. Nevertheless, I will mark this as resolved now.
