Also I have noted that I get no boot screen etc until the PC is booted into Windows.
DONT BUY same issue as Hazro's monitors seems they still have yet to get any testing done with certain GFX cards. This is a pure fail and everyone needs to take this into account before you buy.
This problem still exists on the Hazro monitors and they refuse to do anything about it blaming firmware on "some" GFX cards.
