Question about Acer AL1917W LCD Monitor

1 Answer

"No signal" error message, then monitor turns off, then on again

Every time I am on the computer (and I only use it for internet at the moment) my monitor comes up with a little error message: "no signal"-it stays there for around 60 seconds before switching the monitor off. The monitor stays off for about 5 seconds and then comes back on. After about 30 seconds the "no signal" error comes back on, and the cycle continues. The computer keeps running (i.e. you can still type and hear sounds) and I've checked all the cords and connections. Also haven't installed any new software recently, but I pretty well use it just for internet. It's not my normal computer so I don't really know much about the system itself, but it seems like a simple enough problem to fix...if only I knew how! Any help would be much appreciated.

LG Monitor worked fine. I put it to sleep I started my computer later that day and monitor has message -D-SUB No Signal Will to into save mode shortly.


No mystery here, if you can read "-D-SUB No Signal" then it's just your LG Monitor letting you know that everything is OK with it, but you still might want to unplug your computer so it will properly wake up from snoozing. Sorry to tell you this, but it will probably happen again. So turn off that sleep feature as recommended by screen experts. Remember this feature was concocted more than 30 years ago for computer monitors that have long since been discontinued.

I've got a Scanport H21 monitor that the green light comes on but has a black screen. Can not dring up a menu or "VGA IN" message.


I am in computers. This is either a #1. display that is going out. #2. the video card fails some times, #3. or the monitor is not plugged in all the way. #4. The VGA cable is not firmly attached to the Momputer/monitor. Your VGA IN message that the computer does not have its signal to the monitor that the connection to the computer is good. God Bless

How do I turn my computer computer monitor on


the signal out of range error is usually down to the screen resolution being output from the graphics port is not supported on the monitor.
if the monitor won't turn on and all the leads are in the right place then it's probably broken.

When turned off for the night, it takes forever for monitor to turn on, the lights on the power button constantly change colors before the screen will work. Is this computer or monitor related?


Hi,
Maybe your monitor's having trouble getting power. Try plugging it out, and then in again. If that's not working, call you're monitor's manufacturer (if you don't know the number, try searching on the internet). Or maybe that's not the case. Maybe your PC takes time sending the signal to monitor. Call the computer's manufacturer (if you don't know the number, try searching on the internet). Hope that helps,
Daniel

Screen saver displaying unwanted message


This happens on monitors with a sleep type function. Make sure that the sleep mode is turned off and that it is set to never turn off inside of windows. Then the no signal error should not come on again.

Screen shows message "no input signal" and monitor goes to sleep.


monitor show "no input singnal" error masage when not gating any type of video singnal ,
so if u realy check your monitor wires for correctty plugged in .
then:-

Two possibilities:

either the video/mainboard of the monitor is defective; or
the video card/ CPU is the faulty.

A way to verify is to try the PC with another monitor or to try the monitor in another PC.

thanks

NO signal error


Hi sir,

Hope this will give you ease of mind and or hints. The No Signal error screen message is normal it depends how much delay it responds to (design or default time delay) the video card down to CPU and control units. The blank screen can be resolved by turning off the screen saver(s) you have and even to BIOS mainboard setting; disable the "turn off monitor after how many seconds" or related menu, etc.. Hope you can manage to enter BIOS maiboard setup.

Best regards,
