Change primary monitor

[Cassius]

My syncmaster 940bf is stuck into standby. When powering it up the monitor takes a while to go online. When it goes into standby, because nothing is happening on the screen, it takes a while to snap out of it. It seems to safe this mode in some way, because even after cutting the power and testing it on a different computer it wont show an image or the menue. The standby LED just keeps blinking. When it goes on it works fine. It did not go out on me either. Only time I have issues is when powering up, the TFT does not show an image right away, but snaps out of it. When I am gone it goes into standby, because nothing is happening on the screen I guess. When I come back, unlike my CRT the tft takes a bit to out of standby. The led keeps blinking as if it is into standby and if I remove the cable the LED keeps blinking as if it was connected to a powered off computer, instead of showing the on screen menue.

Now it seems to be stuck into standby for good, the LED keeps blinking and I have no idea what the reason is. I think its some kind of error, because when it works, it works fine and it never went out on me while I was using it eiter. Can the TFT cable communicate with the hardware in some way, or is it just strictly for transferring the image signal?
