Asus MB169b+

Hello everybody,

I'm using the Asus MB169b+ (is a USB monitor) with my MacBook Pro (Retina, 13-inch, Mid 2014 with EL Capitan).

After installing the driver it works, but some colors are not so good.

I can't make a screenshots so I will try to explain with Google Maps as example; The gray color they use between the streets are not visible on the Asus screen but are on the MAC screen.

Another strange thing is that when I turn off 'Reduce transparency' in the 'Accessibility settings' the hover color in the menu bar is white and then I can't read the white text. (I use the dark color for menu's and windows).

Does anybody have an idea what this is and how I can fix it?
