What is the triggering signal to power on the monitor?

Monitors on standby mode change state when they receive a signal from graphic card. I would like to know what is the trigger signal for the BenQ monitor to power on, is it the horizontal, vertical, video signal, ...? This is because i have a monitor which remains in the standby mode even with signals present but i have no oscilloscope to investigate any further. Any help will be appreciated...

Monitor stays in standby mode(power save)

If the monitor will not power up to give an image on the screen, try to connect it to another computer and see if it works. that will eliminate hardware failure of the monitor.

Check the vga cable connection from the computer graphics card to the monitor and make sure the connections are tight.

Then test the computer with a known working monitor, if it fails to work, the graphics card on the computer is at fault.

If replacing the graphics card does not work, try clearing the CMOS on the computer.

The screen is black and a blue box in the middle that states "analog out of range. 67.0kHz/60Hz

Try to see if this works on another computer first, if it does, then it assumes the monitor is ok.
Then as the computer boots up, boot to safe mode by pressing F8 and once in that state, set the display to a mode that the graphics card will support.
If none of the full colour options work, the graphics card may be incompatible, try changing the graphics card.

Monitor all plugged in all cables fine when pc boots up monitor power light come on and screen says "no audio visual signal" help!

Does your computer have more than one location where the video-cable can be connected?
If so, connect to that alternate location.

Try connecting the monitor to a laptop, to see if the laptop can send a signal to the monitor.
You might have to "toggle" the laptop (internal-screen-only / external-screen-only / both-screens)
to activate the external screen.

Monitor goes dark

If the power light turns yellow, there is no signal being received by the monitor from your computer's graphics card. The screen will shut off (go into idle mode), which is a low-power state, that saves energy. Check that the cable on the back of your computer is plugged into the right graphics card (many PCs come with more than one, these days). There may be one built into the computer's mainboard, and another one may be on a separate graphics card located somewhere else on the machine. Only one of these will work on startup. If one doesn't work, try the other.

Hello we had our power go out yesterday. we thought there was a problem then with the monitor so we purchased a new monitor. When hooking up the new monitor it is doing the same thing the light is blinking...

This monitor is connected to a computer ?
If so then it is going into "sleep" mode because it is not receiving a signal from the computer.

If the power went out whilst the computer was on then there may have been damage to the computer.

If you have another computer (or a friend with one) you can connect your monitor to it to see if it works.

Monitor has power but says not receiving signal and frequency out

Hi, this might be a cable plugged out from your graphics card or from your monitor. Check that first. If the cable fits ok, try changing it with another one to see if it is ok or broken. If it wont do anything, it probabbly needs to go to service for mainboard replacement. Something simillar happened to me too.

My monitor gets switched off when i connect to cpu,the moment i disconnect it from cpu,its switches on automatically.what may be the problem?

One of two things:

1.) Your video card is 'stuck' in standby mode, which in turn sends a signal putting the monitor in low power 'standby' mode as well. When you disconnect it, the monitor returns to normal 'on' mode. Rebooting the PC should correct this issue.

2.) Your resolution or refresh rate are set outside the range supported by the monitor. When you connect the monitor, it starts receiving a signal that it can't display, so it simply turns off. You'll need to reboot the PC and press F8 quickly to bot into safe mode and correct the monitor settings.

Can't see screen to install diver for HP Compaq WF 1907

My friend just purchase this monitor yesterday. When she plugged it in to the back of the tower she received the same prompt u have mentioned. I was able to repair it because she simply did not realize that I had installed a new graphics card into her pc a few months ago. When u do this, you have to hook your monitor into the area where the new graphics card was installed. You can not plug your monitor into the same onboard card that u have previously plugged your monitor into.
Let me know, if by chance, u did install a new graphics card.
Hope this was helpful :)
