Strange displayport behavior
Posted: Thu Jan 03, 2013 3:12 pm
Hello,
I have the following strange displayport behavior ?
Did the following.
Only one pc is attached to the monitor and that is the displayport.
Restart the PC.
Go inside the motherboard bios, it dont matter stay in bios boot/configuration screen.
Turn off the monitor for 30 sec
Start the monitor again
The screen stays blanc no display nothing.
Disconnected the displayport cable.
Connected the displayport cable.
The screen stays blanc no display nothing.
Turned the monitor power off.
Turned the monitor power on.
The screen stays blanc no display nothing.
Turned the computer off.
Turned the computer on.
The screen works again.
When I follow the same test procedure on the hdmi port these issues do not occur.
Is this problem displayport, displayport-cable, bios, (driver) or display related ?
This issue also occurs inside a running windows 7 for some reason the displayport looses connection "OSD message on monitor about resolution not optimal" and the screen stays off; removing the displayport cable an attaching it again fixes this.
