SOURCE: monitor goes to sleep no input signal only 1 mo old

Normaly the monitor is not picking up the signal from the PC, it could be VGA cord is not connected, faulty, or the video card is faulty,or the monitor is not compatible to the PC. It could be one of my suggestions. Trouble shoot by connecting your monitor to another working PC and see what happens.If not the VGA cord is faulty and not picking up signal from the PC. Hope it helps.

SOURCE: monitor goes to sleep and never wakes up

I have called HP Technical Support 6 times about this issue and have logged at least 14 hours into the issue. The things they have done are turn all sleep settings in the "Power Options" in the control panel to "never". The problem persisted. Today, they sent my problem to the complaints department, so maybe they will have the authority to do something for my 5 week old setup.

For me, the monitor was in the "other devices" part on the device manager (go to start menu and type device, and the device manager will show up). I went to HP's website to the support and drivers spot and found a patch for the My Display program. This will allow you to uninstall your monitor, just right click the monitor under "other devices" and click uninstall. After you uninstall, restart and your computer will recognize the and put it under "monitors" in the device manager with the updated drivers. After I did this, the monitor hasn't gone to sleep.

I have a acer.x223w when,it powers up the.screem stays black, n i get a blue blinking light on.the bottom


I disagree with ikkenom only due to the symptom of the flashing blue light. This would indicate to me that the monitor is not getting any display signal and is in sleep mode at least the is what happens on my Samsung monitor. Used to be that they use a two color led in the monitor, green when ON and getting display signal and amber or orange when in sleep mode. I would check the computer by trying a different monitor. If you have a second monitor, great, if not, maybe a friend will let you bring your computer over and try the computer with their monitor. Could also be a display adapter setting. Do you get any change when you first turn on your computer? i.e. Do you get the BIOS or manufacturer screen when first turned on? Also if you disconnect the monitor cable from the computer and power cycle the monitor, do you get a No Signal display for a few seconds before the monitor goes black and the blue light starts flashing?

Let me know what happens with the testing above or if you need further instructions to carry out testing.

Thanks, Jim

I have my acer p205h 20 inch monitor hooked up to my tobshiba laptop and it works great except it will not go into sleep mode when laptop goes into sleep mode the monitor goes to there is not signal check...


Unfortunately, this is a standard problem, as when your laptop goes into sleep mode, it shuts off power to the secondary monitor, without giving it the signal to go into sleep mode. You could try digging around your settings, but most likely you'll just need to turn off the monitor when you're not using it.

I changed some setting for the computer resolution and now my monitor just says no input signal..the hard drive turns on and then goes into sleep mode and says no input signal. How can i fix this problem?


Possible reason is that input signal goes out of range that probably a Screen refresh rate that the monitor cannot handle. Instead of bursting into flames, the monitor shuts itself
down as a protection feature. Look at the monitor manual if you got one.

Safe Mode should allow the monitor to work in the problem account.

Try this.

Boot in Safe Mode (see below)
Switch users to the problem account
Right click the desktop
Select Properties
Click the Settings tab
Click the Advanced button
Click the Monitor tab
Select: Hide modes that this monitor cannot display
Select a different Screen refresh rate
Click Apply twice and then Click OK

Or try this:-
power on the system and press and hold F5.
When a screen appers with some option, try to find a option something realted with VGA setting.
Click that option and let pc start normally.
It will surely work

The monitor starts up displaying no signal


This means that the monitor is not receiving a video signal from the computer. When it doesn't receive a signal, it goes to sleep. You should check to make sure that the video cable is tightly connected, and also, if you have another monitor around, connect the other monitor to the computer and see if it works. It's possible that your monitor has malfunctioned.

My Computer boots and montitor says Going to sleep and flashes VGA : NO signal and goes off


Check under "Power Options" of the control panel of Windows that "Turn off Monitor" is set to "Never" Also check under the advanced tab of "Power options" that "When I press the sleep button on my computer" its set to "Do Nothing"

This will most likely solve your problem. the sleep button may be stuck on the keyboard causing the pc to quickly go into sleep mode
