U2414H cannot display white

I had just received my Dell U2414H monitor this week and used a for a week.

I am really frustrating that the monitor cannot meet my expectation very well.

As it is told to be a color calibrated monitor, I thought the panel of it will be much better than my old TN panel monitor.

However, when I receive my monitor, I immediately feel the panel is extremely yellow and cannot reproduce correct pure white color no matter how hard I try.

Also, even I use MS paint to make an white png image and display in whole screen. Not only the screen is yellowish, there are clearly some color shift from left to right. The left side looks yellow and the right side looks greenish.

It is very annoying as when I browsing through the web, all the websites looks yellowish especially on sites with white background like Google and Youtube.

Here is an image of the yellowish white compare to that of my old monitor (Camera cannot capture the difference but it is more noticeable by eye)

Here are those additional informations
