Well, I'm found workaround. Try to change external display mode to "Mirror for Buit-in display" and then reboot. After reboot, on initial login, external display may be black (no signal). Login and change back external display mode to "Extended display", check before that Rotation parameter is "Standard". Reboot your Mac again. After this manipulations, in my case, external display is in landscape mode again on initial login.
