External monitor does not Standby

March 23, 2011 at 01:18:05
Specs: Windows 7
I plugged in my external monitor to Vaio laptop. And I've set it to be as my primary monitor via ATI control central.

But the screen does not go into standby after I shutdown the laptop it gives me a no signal message.
So how can I make it standby ?

Thanks.

Is the display identified by Windows using the brand and model, or just plug and play?

Then you need to get Windows to identify the monitor by model. Post the model of the external monitor.

Download and install the driver for that display. Get it at the link below. You should have gotten a CD with the monitor.

So, do you momentarily see the no signal message and then the display is dark? If not, describe what does happen.

1. Shutdown laptop

2. Screen gives no signal message

3. It stays this way it does not stand by

4. So I just Shutdown the screen


In other words if the computer is OFF then the screen gives no signal unless I turn ON the laptop.

If you are completely shutting down the laptop then the monitor can't go into standby mode because there is no OS to control it. I think you will need to either use standby for the laptop or better yet, from an energy stand point just power down the external screen.

You understand that even if you get the external to go into standby it is still powered?

Yes. But What I do not understand is why does the external go into standby when connected to normal tower pc but does not work when connected to a laptop ? (And the part about the OS not controlling it why )

Are you stating that when using a desktop computer you can totally shut down the computer and the monitor will be in standby? I don't think so. Standby is a feature controlled by Windows. Once Windows is no longer running it can't control the monitor.

Are you sure you are totally shutting down in either instance?

Windows can only control the signal to the display when it is an external type. I think if you wait a while the "no signal" message may go away. The monitor will still be using some power. Best to shut it off completely.

The No signal message is being generated by the monitor itself.
Windows cannot make the monitor go into Standby mode when Windows has been Shut Down.
The laptop does not connect the video adapter to the external monitor, it's secondary display, after Windows has been Shut Down. It connects to the external monitor while booting the computer.

Simply switch off the monitor's power switch

yes "It connects to the external monitor while booting the computer." so is their a way to see my bios cause I need to dual boot using the external monitor. Cause As you said it only connects when windows is ON.

Why can't you select which operating system to boot from on the built in display ?
Is the built in display not working properly ?

The only thing you can set in any bios I've seen is which display is the Primary display, if you have a choice at all on a laptop.

On a desktop computer, you usually have at least two choices for which display is the Primary display, but I've never seen any Primary video setting at all in the few laptop bioses I've seen.
