I had the same issue as you describe, and fixed it by swapping to another
cable.  The 
poor connection was at the P3 side of the cable.  Once swapped out, I also
found that
my USB sound card was radiating a lot of noise as well.  I had to both swap
cables and
unplug the sound system to get to a nice flat display.
