    HDMI connection to Toshiba flat screen output from HP, Windows 7 and Nvidia graphics. Excellent operation except that if I switch the LCD from the HDMI of the PC to another input, i.e. to watch TV or DVD etc. and then sometime later come back, the PC shows nothing but a screen full of "static". The desktop is gone, although I can still operate the computer (without video) so it is not locked - only the video output has failed.
    This does the same thing if I boot up without the LCD selected for the HDMI input from the PC or when I awake from sleep mode without the HDMI for the PC selected.
    Has anyone seen this, or aware of a possible fix?
