Monitor Turns Black - Won't turn back on when moving mouse

My monitor turns off whenever I leave it idle for more than 2 or 3 minutes. But it will not turn back on when I use the keyboard or move the mouse. It will only sometimes turn back on when I either hardboot the computer or unplug the computer entirely.
What's wrong? How can I fix it?

It is probable that the ROM system, called BIOS (Basic Input/Output System), is set to not wake your computer by moving the mouse or pressing a key on the keyboard.

I do not know which BIOS your computer is running so I can only give a general answer.

When your machine is starting up, look for a message that says "Press F2 to enter BIOS" or something like that. Your machine may have a different F key assigned to enter BIOS.

There should be a setting in there that allows you to change the values for waking the monitor. It should say something like "Use keyboard and Mouse to wake up computer", it won't say those exact words, but something like that. If the value is set to disabled, then enable it. Then save your changes and exit (Usually by pressing F10)

Be careful when in BIOS. Changing settings you do not understand can make your computer behave erratically or stop functioning altogether.

SOURCE: Monitor goes to white at cpu shutdown

The problem is in the "soft switch" technology: On some of Sylvania's newer monitors they have incorporated what is called "soft switch" technology. This allows your ATX power supplied computer to turn your monitor on and off using it?s software controls. Therefore, your monitor?s light will always stay on blinking even when your computer is off. The monitor in normal operation consumes about 80W of power; in the "OFF" state it will be reduced below 8W. The "OFF" mode of the monitor can be controlled by the PC input signal or by pushing the soft-power button to disable the PC signal control for manually turning off the monitor screen. Thus, when the monitor is in soft-power "OFF" mode it still consumes a very small amount of power. For the purpose of making it noticeable to the user that the monitor is in soft-power "OFF" mode, we designed the power indicator to provide for a slow blinking signal (every 2 seconds). If you need to totally turn off the power, then the power cord would have to be unplugged. The same is true of the PC itself, but the PC does not provide for notification while in "OFF" mode. Your monitor looks like it may be in need of repair, contact info: PTI Technologies Inc. 7372 Doig Dr. Garden Grove, Ca 92841 Phone: 714-799-3899 Fax: 714-379-6290 Hours: Mon - Fri 8:00am to 6:00pm PST

SOURCE: When I power off my LCD Monitor

If this has happened to two monitors on the same computer, then i dont think the problem is with monitors, i think the problem is with the graphics on the computer, i suggest uninstalling the driver for the graphics card in device manager and then restart the pc to see if that makes any difference. The divice manager in in the properties of my computer icon, just right click and choose properties, then device manager.

My computer works normally but my monitor suddenly turns dark. I try to turn off the power (monitor) and when I turn it on back, it turns to normal. but few minutes later, the problem goes back. This...

Does this happen when you leave your computer idle for few minutes? If so,then the Pc is
simply turning off your monitor to save power when you don't use it.And you can turn it back
on simple by hitting keys on your keyboard or moving the mouse to and fro.However if you
would like to disable/change this option the please do the following.

If you are using Win XP,then

1.Click the windows Start button,then click Control Panel,click Performance And Maintanance
and then click Power Options.

From the window that opens,choose the time period after which you would like your monitor to
get into power saving mode (the default is 5 mins) or choose 'Never' from the drop down box
next to where it says 'Turn off monitor'.Then click the apply button and finally the ok button.

If you are using Win 7 or Vitsa,the please follow the following link to learn how to disable this option.

Yes. Do not turn the monitor off by its power switch, let the computer do the work for you. Alot of times when people use the power switch to turn off the monitor, the computer sees that all of a sudden the monitor has been disconnected from the pc. when that happens the pc sees it as a device beimg unplugged and removes that certain device from the pc's list of things that should be connected, and when you turn it back on the pc sees it again and starts loading drivers for that new part(monitor)

My monitor turns itself on and off with no prompting

Go into the control panel and check the system settings. You might have it set to turn the monitor off after a low number of seconds of use. If you have it set for 30 seconds, if you don't use the keyboard or mouse for 30 seconds, the monitor will shut off. When you start to use it again, it will come back on.

Monitor turning off

If I understand you problem correctly, your monitor is turning off when it remains idle? Does it come back on when you use the keyboard or move the mouse? If so, then this could just be caused by the computer's power-save settings. This can be adjusted by right clicking on the the desktop and selecting propeties. Go to the screensaver tab and click on the power button. From here, you can either set the "Turn Off Monitor Time" to never, or to a greater period of time.
