I unplugged the speakers and all near power 'bricks', with no change in
focus.

The monitor is plugged in together with the PC into a power strip,
located about a meter below the monitor (on the ground actually)

But if the problem is magnetic/electrical interference, shouldn't I have
experienced the problem with my old monitor too?

Also, remember the unsharp picture occurs when I'm using high refresh
rates (85 Hz, 100 Hz, ...), and the picture is more or less OK starting
from 70 Hz to 60 Hz.

I also noted an unsharp picture, horizontally in the middle of the
screen, and vertically in the upper half of the screen:

An x means loss of focus.

Kind regards,

Okay - you seem to have eliminated the easy ones - so it is probably time
for the monitor to visit a service engineer.
