Hi Elidapoca,
How old is your monitor?
Did you try using a different VGA cable to check if that works?
Have you hooked up another monitor to different cables to see if the same problem exists. If that works then you deffinatly have a bad vga port on your computer.
Also, check if there is a setting called Color Temperature.
What’s the model and make of your Monitor?
Go through your monitor installation guide and check if you’ve any settings on it.
I would also suggest you to contact your computer manufacturer.
