At work we have a PC connected to a Sony KDL-40W2000 TV.
The PC has a DVI output which is connected to a HDMI input on the TV via a
suitable cable.

If you turn the screen on , select the HDMI input and then boot up the PC
then we get a picture.
If you then turn the TV off to standby or off entirely , then turn it back
on we get nothing. You see the av-5 graphic on the screen and that's it.

We need to reboot the PC before the TV will display the picture again which
is a major pain.

Any suggestions?

This happens with both PCs we have tried , and also using Vista or XP.
It seems that the TV is after a "switch on" signal before it will display
anything.


Alex,

If this is a MediaCenter PC try pressing the windows menu key & see if
it show the start menu, if it does then a downgrade of driver (ATI)
fixed this for me (it was a problem with the overlay not being on the
primary display).

If not - see if your graphics drivers have a setting for allowing
hot-key change of resolution - ctrl+alt+numkeyplus or something like
that - and try switching resolutions down and back again.
