This band appears right from the laptop startup and runs through the logo too. The same gray screen appeared after about 10 minutes. Do you still see the same stripe on the screen in BIOS setup and it covers part of the image? I had what seems to be an inverter problem, no backlight at all very dark image and the external works perfectly. This affected not only the individual green box, but also the box containing the combined colors.
