Gryphon Display.
 

Well started my truck today looked at my gryphon and the screen looks faded. I stop then start and it is still faded, I can not read the numbers very well. I have not adjusted a thing. Is something failing?

I've had this happen to me a few times, it's like the display settings are changed somehow without the user doing anything.
Also to much heat will make the LCD screen look lighter than normal untill cooler temps are reached.

You can go to the main menu, select [Settings] -> [Display Settings] -> [LCD Settings] -> [Adjust Contrast] and raise the contrast level a little bit. That should help darken up the display for you.

Take care.
