i just noticed that when i started my truck today that my gryphon's backlight was like dimmed or faded kinda look so i unplugged it and plugged it back in and it was bright again. Is this normal

 

i have had that with the contrast.... it get so dim you can barely see it... then when u go into the settings to adjust it, you push up 1, and it gets perfect again....

i have had to do that a few times so far... not sure if theres an update for it or not..
