I have been working with HP on an issue with our HP Elitebook 840 G4's where the monitors will occasionally go black for a few seconds when connected through a docking station. This appears to only be an issue when using VGA to DP adapters (we have tried several including HP brand ones). We have roughly 300 computers and a majority of our current monitors do not have DP port connections, so replacing monitors is not an option. They have given us several driver update and suggested sending the machines in however it effects several so I don't suspect all of the machines are having issues. In the last email they send the following,
"I checked with my resources and gone through the case thoroughly. I would like to keep you informed that VGA to DP adapter will not work since VGA is analog input and DP is digital input. You can connect directly to the DP port or directly to the port on the docking station.
You cannot use the adapter and it will have issues."
This can't be the case can it? The dock does have 1 VGA connection on it but most people use 2 external monitors. Is there any way to get these to work without issue? HP has basically said they can't help any further and the adapter will not work.
