After install KB4038788 update, on boot after shutdown (not after restart) the second monitor remains in stand by. On both system, I see the win logo and on login the right monitor go in stand by mode. One system is configurated with primary monitor on left and secondary on right, second with primary on right and secondary on left. In both system the right monitor start in stand-by. The only mode to reactivate it is on screen settings and deactivating/reactivating the second monitor.
In one system i have uninstall the update and it has returned normal, but in the other the uninstall procedure has not been successful.
Both graphic board are Radeon HD with default microsoft driver.
Any idea or suggestion to solve the problem?
Thank's in advance
