Colors look washed in PC Mode Samsung NU8000

[NYCKicks]

So as of recently I picked up a 55 inch NU8000 from Samsung. Netflix, Hulu, YouTube etc look fantastic. Colors are vibrant, blacks are deep black. The whole 9 yards.

However, when connecting to my pc, colors look so washed and just look horrible compared to the TV menu and so on.

My pc specs:

I7 3770k
Gtx 760
16gb ddr3

No idea what it could be.

There is a setting somewhere which sets the HDMI input to accept a HDR signal, on my TV it's called UHD Color. Make sure that's enabled for the HDMI port used and that in the Nvidia control panel the color space is set to RGB Full.
