I have about 10 7970?s that have applied a custom background image to. The custom background is white with colored text. Most of the phones display this correctly with the line appearance or assigned speed dial buttons readable with a solid gray bar and the button assignment in a white font. On three or four of the 7970?s you can not read the button assignment, the solid gray bar is missing and the white display text blends in with the logo. Where is the setting to change this? Why is it working on some but not all?
Thanks for the help
