Screen goes to sleep after "no signal" message

Sounds like you have something overheating in the screen pull the back cover and blow it out.

if the message you recieve is no input signal if only means that you have a problem with your video card, the monitor is fine but you need to have your video card check

If it's not showing anything and goes to sleep mode, then did you try to select the proper input from the monitor's on-screen menu?
Otherwise I can't help you unless you are more specific - when does it go black, right away or after 10 minutes of watching a movie for example?...

This happens on monitors with a sleep type function. Make sure that the sleep mode is turned off and that it is set to never turn off inside of windows. Then the no signal error should not come on again.

monitor show "no input singnal" error masage when not gating any type of video singnal ,
so if u realy check your monitor wires for correctty plugged in .
then:-

Two possibilities:

either the video/mainboard of the monitor is defective; or
the video card/ CPU is the faulty.

A way to verify is to try the PC with another monitor or to try the monitor in another PC.

thanks

Have you recently installed a new video card? If not then you need to because the one you have is broke. If you can plug in another screen to see if that works and if it does then you should re-install the software (if any) that came with the new screen. If you need anything else please let me know.

Hi publicworker,

I had a similar problem whereas my monitor went to sleep mode after a few minutes. I'm running an HP LP 2065 in dual mode with another HP flat screen. However, I did resolve the issue after resetting the output settings.

How to do that:

• right mouse click on the desktop
• select graphic options
• output to
• extended desktop

Maybe some changings/modification will help you too.

It will do this when it's not getting a video signal from the computer. Make sure that the signal cable is firmly plugged in at both ends. Also verify that the computer is actually starting up. The monitor may not be getting a signal because the computer isn't sending any.
