I understand you are getting yellow hue on the main screen (bulit-in LCD) of the laptop.
This may sound like you have a hardware problem with LCD screen of the laptop because you are saying it looks great, this has to be handled by your computer manufacturer if indeed the screen has some issues.
If you like to change monitor position to default secondary monitor. See below for more information:
