Given that switching the cables doesn't change the messed up display,
that really strongly points at the monitor failing. I assume that when
you switched the cables, the working monitor showed the other part of
the desktop. Do you have another computer to try the monitor on?
Assuming it's the monitor, is it realistically possible to replace bad
components (a cpu, memory, etc.) within the monitor, or are such
components available only to monitor manufacturers? If replacement is
possible, how can I determine which components are bad?
