And another monitor on this PC?
That's how you tell where the issue is.
Since about a week ago, my Samsung monitor (BX2031) display is very poor. Contrast is bad and the colour from all internet sites are all wrong. I attach some examples. In the one, the black and white is reversed.

My computer specs are:
Graphics card: NVIDIA GeForce GTX 260
Windows 10 Professional (x64) Version 1511
3,10 gigahertz Intel Core i5-2400
64-bit
Multi-core (4 total)
MB:H61M-P21 (MS-7680) 3.0
HDD's:
SAMSUNG HD105SI
WDC WD1003FZEX
I have tried what I could think of, changed the settings on the monitor as well as the computer, changed the cable, checked the ADSL connection, etc.
Could someone please give me advice?
