just purchased this 2011 silverado 2500 and during my first drive the right side of the display fades out. it could fade just the right bottom corner or fade the whole right side so far the left side is always there but there is these wierd symbols that appear at the bottom of the display

 

Having the same problem with mine. Haven't figured it out so I will probably just replace it. I figure it's internal and there's not going to be a fix that I can do. Good luck
