home windows 10 colors faded

Hi, I am hoping anyone can assist me please.

I’ve simply purchased a Dell Inspiron 3505 working Home windows 10, I am actually dissatisfied within the colors at the display. The whole thing seems washed out, very boring colors and the print is gray now not black so very tough to learn. It is evening time now and with the electrical lighting fixtures at the display is ugly to make use of.
I adopted recommendation at the Microsoft site assist pages and attempted to Repair Vintage Context Menu, through now not permitting this Immersive Context Menu to be loaded, however not anything modified. This greyed out glance it is simply terrible.
I might be very thankful for any assist please.
Thanks.
