I have just bought a RX570 Graphic Card. I have two monitors: The first one has only HDMI port, instead the second one has only a DVI port. On windows 10 with AMD driver the DVI screen does not work!
Before you ask: cables works. I have a dual boot with Linux and both monitors works without any problems, also, Windows 10 with generic video driver is able to display on both monitors!
The problem is exclusively when windows 10 installs OFFICIAL drivers from AMD. Indeed, after installation the DVI monitor stop working.
There must be a issue with your drivers... I need a fast solution.
