No, but I get a message from the pc to say it is going into power
saving mode but nothing happens.
Then some time later the 275t goes blank.

So what I think is happening because my monitor is plugged into a
laptop, is that the monitor has a mind of its own, and powers down when
it does not get a signal. i.e. it does not power down on getting a
command from the laptop.
When I move the mouse I get the screen back straight away.

I have an IBM 855 video card which I think is pretty basic.

xrandr -h does not indicate one.
