Solved the deployment problems with an USB C adapter with the network cable connected to the adapter. And In the bios set the hard drive from Raid to UEFI. The resolution is still not correct but at least we can deploy new computers.
Hi forum, We use Microsoft SCCM for deploying our Windows 10 image to new computers.Bought multiple Latitude 5531 since we need a faster system. When we boot the laptop via PXE booting the resolution changes and looks way to zoomed In.After the image has been loaded, a small window should appeare that you can select an image or fill In a password.This does not happen on this model. We can deploy older models like the Latitude 7200 without any problem and this gets added In SCCM the same way like the newer model.Is there anyone that sees this same behavior? Note: I've found post below from a different Dell model that has the same problem. A bios update fixed that one but we are running on the latest version at the moment since today. [URL] Any advice what we can do to fix this? Tried all the steps people sayed In the above community post but no luck yet.
