Monitor gets no more input signal after turning off and on (computer still runs)


P

Peter Swindon

In former times I could turn off my TFT monitor (with running WinXP computer).
After a couple of hours I returned and turned on the TFT monitor again.
After 2-3 seconds the TFT monitor detects the physical signal and the WinXP desktop is shown as intended.

Since a few days this does not work any more.
When I turn off and (after a while) turn on the monitor again there is only a message "no input signal"
and the screen remains black.

So there must be a settings changed. Most probably with ACPI or power management or driver setting.

How can I make the TFT monitor re-work again?

If you have multiple inputs (VGA, DVI, DPMI) on the *unidentified*
monitor then there should be on-monitor controls for selecting which
input to use. The auto-select may not be automatic at all. Instead
the 2-3 second lag you saw was merely the monitor waiting for a valid
video signal on whichever input to which the video cable is connected.
You may have to use the on-monitor menus to select which input to use.
