Try tech support for the monitor. I had an analogous problem with a new
Samsung monitor and it also turned out to be a cable problem that I would
never have solved on my own. Oh, I think maybe it was tech support for the
video board.
Sometimes it's worth going directly to "the source" for tech support problems.
