My screen res was fine before I got an upgrade.I upgraded my gpu to a gtx 1050 and also got a second monitor.Ever since I used the new Gpu and second monitor my main monitors res does not fit in the screen.
My main monitors default res is 1680x1050 and I have it on that but it stil does not fit everything on the screen.
The second monitors resolution is 1366x768.But when I choose that resolution it says "Not optimum mode,recommended mode 1360x768".
There is a clear cut of the screen(I cant see the full sircle of the windows sircle in the taskbar)(My taskbar is cut of).

Please help
