I moved my computer into another room and back into the same room, now the 3rd monitor isn't working. I'm using Windows 10, with an AMD FX-6300 black edition processor. When attempting to extend the display on Display Settings it says "The display settings could not be saved. Please try a different combination of display settings."
Driver: AMD Radeon HD 7800 Series
DirectX Driver Name: aticfx32.dll
Driver Version: 15.200.1062.1004
DirectX Driver Version: 188.8.131.524
I believe it's a Sapphire HD 7770. I'm using a DVI to DVI cable in the DVI port, a DVI to HDMI cable in the HDMI port, and a DVI to DVI cable with a DVI to DP active adapter. In this configuration, it worked before I moved the computer. I've got 2 HP W2072a 20" monitors and one AOC 20".
Here are the steps I've gone through:
- Restarted my computer
- Unplugged each input and plugged it back it.
- Able to use 2 monitors, but not all 3 at once.
- Uninstalled drivers and reinstalled.
- Uninstalled all AMD software and reinstalled.
Like I said, it worked before and I don't understand why it's not working now even after all the steps I'm going through.
