After upgrading to Windows 10 the external display is not recognized. I have updated graphics display adapter driver, rolled it back, updated again. No luck. Bios update, everything else I could think of, no luck. I have a Lenovo Thinkpad T450, barely 3 months old. The display is connected via a ThinkPad Basic USB 3.0 Dock. Graphics are Intel HD Graphics 5500. Any help?
