Is there any way to disable detection of the displays connected through DVI?

I have a mac mini and a panasonic plasma TV connected through a DVI->HDMI adapter. When i connect the TV to the mac, it detects the display and it's configuration. Everything works perfect. But when i switch off the TV and on again, the mac doesn't activate the video signal.
I have to disconnect and reconnect the TV to get a signal. Even a reboot doesn't help.

So, is there a way to let the mini think, that the display is still connected to the TV even when the TV is switched off? Or is this a hardware functionality of the graphics card?

QUOTE Thanks
