I have found an interesting black screen phenomenon. Sometimes when the PC wakes up, and almost always when I press delete key to enter BIOS, I get a black screen. I have discovered that if I move the mouse or hit the space bar enough the video comes up and all is well. As a last resort, especially when entering BIOS, if I cycle through the HDMI inputs back to the computer HDMI input, the BIOS screen comes up. When I get the black screen it does look like the computer is frozen, but using the methods I described here, the display comes up. It appears to be a computer to display HDMI issue, and not a real lock-up. |
