Hello, I have AMD Radeon HD 5700. I have three monitors plugged in; one in the displayport, hdmi, and dvi. My windows 10 recognizes all three but will not extend to the third monitor. When I choose "Extend desktop to this display" the pop up comes up asking if I want to keep or revert the changes but the third monitor still doesn't come on and when I click accept it says on the menu "The display settings could not be saved. Please try a different combination of display settings." Never get a reason why and if I unplug one of the other connections the dvi monitor comes on but I can never get all three on. How do I extend to all three displays at the same time? Thanks in advance.
