I do have a somewhat similar problem, but mine started on Windows 10 and continued on Windows 11. For me, the problem is that my Surface Book 2 and Dock 2 randomly does not recognize my Samsung 49" curved monitor on startup or waking from sleep or lock.

I have contacted both Microsoft and Samsung about this, but no solution have been found.
