How to modify color display

Good Morning,

I am a photographer. My pictures straight out of my camera are great on my older 17in Dell. It has Vista as the operating system. In order to purchase Photoshop and Lightroom CC I had to have Window 10. I purchased a new 17in Dell, but the colors on the monitor and the actual pictures straight out of the camera ( from camera card) is not as good as the older Dell. Faded and not as brilliant . Can someone tell me how to correct the color on the monitor and for my pictures on the new machine.
