I'm so glad that my post has had a lot of interest! I found a good solution for me without having to calibrate this brand new Dell xps laptop. I could never find a way to simply tweak the saturation, until I changed a setting to put it into HDR mode. It worked like a charm. Now I have a different problem. When I use my GE hub to mirror the screen onto my old, large monitor using an hdmi cord,, it goes back to being oversaturated on the laptop! I wonder if that's because my old monitor doesn't support HDR mode.
