There are many reasons. Here are a few in no specific order:
1) the computer is off
2) the computer is in standby
3) the computer is in screen saver mode
4) the computer is in hibernate mode
5) the video card the monitor is hooked up to is not the primary video controller (check BIOS/CMOS settings, hook the monitor to the other video controller till you fix the issue)
6) there is something wrong with the computer (power supply, video card, RAM, motherboard, processor) and the computer is not POSTing.
7) the monitor isn't hooked up to the video card, check the connector
8) the computer is in a resolution or refresh rate that is too high for the monitor. Boot in safe mode and adjust the resolution and/or refresh rates.
9) the monitor cable is broken internally.
10) the monitor itself is defective.
To eliminate the monitor itself as the cause of the problem, hook it up to a known working system. If it works, look at issues 1-8.
Otherwise, probably time for a new monitor.

Why should you enter safe mode when troubleshooting problems with a monitor in Windows XP?
There would be no reason to do this. I have fixed graphical settings and problems without ever going into safe mode. If the problem is with the monitor itself, then safe mode would have no effect. And if it with your display settings, you need only adjust these settings without the need for safe mode. Try checking for driver updates for your video card too. This can help get a monitor working.
When troubleshooting problems with a monitor in Windows 2000 why would you enter Safe Mode?
Safe mode loads the Standard VGA driver, its not somewhat a monitor troubleshooting step but rather a step taken to resolve driver issues. If your monitor displays the first part of the boot process then blanks out while loading the OS it is recommended your boot into safe mode to try & resolve display issues.

Why would a monitor remain in power save mode after installing a Radeon 9250 graphics card?
Monitor Stuck in Power Save ModeFirst I would check your bios there should be a option to enter setup when you power up you PC. If you have an on board video that was being used prior to installing the new card, it may still be selected in your bios, you will have to connect your monitor to the onboard port then make the changes to bios. It should be as simple as choosing to turn off onboard video card. if this isn't the solution then try the following.I would suggest updating drivers before installing a new video card however if you already have the card in and have yet to install the drivers, a possible work around is to boot into windows safe mode hold f8 after turning on power this should bring up a boot menu choose safe mode, from there you should be able to either update drivers (not sure if this is possible in safe mode) or choose a generic video display adapter then restart and update drivers.
I must start my laptop in safe mode for the monitor not to black out.if not started in safe mode it may stay on for a couple of minutes or second literally and may even reach the desktop.how to fix?
Keep it on charge and press the power button. Keep pressing and releasing F8 frantically then stop and press the arrows until it's on "Safe mode with networking" then press enter BEFORE 30 seconds.To stop it blacking out, angle the screen. After a while of angling the monitor doesn't black out. (the same thing happens to me)
When you start a Window based system in safe mode with standard VGA drivers at what resolution does the monitor operate?

Changed resolution on your computer now monitor is blank?
You changed resolution to a mode that your monitor cannot handle.Restart in Safe Mode; to do this (in Windows), restart the computer, and press F8 before you see the windows logo. You may need to press it several times.You should get a menu, and one of the choices is "Boot computer in safe mode". Boot in safe mode, then once your computer is booted, change the resolution to 640x480, then shut down and reboot again (returning to normal mode). You can then set the resolution and colors back to where you want them (and where they work).

If the monitor is an older one, it may not be capable of displaying the resolution the video card is set for. Try booting Windows in Safe Mode, and setting the screen resolution to the lowest numbers. To boot in Safe Mode, press the F5 key repeatedly as soon as the BIOS program begins to run.
