Radeon hd 5700 monitor blank until connected HDMI device is started
- by kaido loor
Have win7, radeon hd 5700. When both PC monitor and HDMI device (Onkyo 607) are connected to Radeon card, the monitor diplays boot info, "starting windows, etc" but goes blank when "log into windows" should appear. Monitor comes back (w normal screen) if Onkyo and TV are turned on, not before. Multiple monitors is disabled. Really crazy. Any help appreciated. Generally, Onkyo can pick up HDMI signal ok, so at least smth works as intended.
