I no longer have this horizontal band issue with my new computer upgrade!!!
this is a temporary computer and I will later update when I find a more affordable computer. maybe an Ivy Bridge I3 Processor and with the same HD 7450 Video Card.
I also have the option of testing the HD4000 Graphics that are built into the I7 3770. I will report back when I do this test.
