I have two displays connected. A 1440p monitor and a 4K tv. The displaycal profile loader shows the correct resolution for my 1440p display but not my 4k tv. My 4k tv only shows 720p even though in my nvidia graphics card settings the proper 4k resolution is selected. If I switch my primary display it still shows incorrect resolution. This does have an effect on some applications because the max resolution that is select able is 720p. Only if I switch it so that a single display is used that displaycal loader shows the proper resolution.
