Tilting the entire keyboard to get a better angle on the display is NOT a solution!
Ask any piano teacher... the angle your HANDS make with the keybed is the critical dimension to be able to play well and without fatigue. If you have to alter this to simply be able to see the display, someone in the R&D team goofed. Plain and simple.
