      Hi. First of all, I apologize my poor english. I am not good at English.

       

      I have Radeon PRO DUO. It's great VGA, I think.

      But after Cold boot, My monitor has no signal and I can't see bios logo.(only black screen)

      After one or two power on, off, I can get the signal. Sometimes, the VGA fan spin on full speed with no signal.

      Plus, sometimes, Screen stays black after waking computer from sleep mode.

       

      I inspected My PSU and mother board and I turned off the igfx device on bios. but it can't help me.

      I will take this vga to RMA, next week. But before RMA, I want to know why this happen.
