The monitor will display that message until the computer starts and outputs a valid signal to the monitor.
If the computer is on and you still get that message, then you may have a bad video card/video circuit or a bad cable between the computer and monitor.

The monitor turns on but says "no signal"


Usually this means either your cable isn't connecting properly to your computer or there is a compatibility problem between the monitor and the computer. Are you getting the "no signal" message AFTER you have connected the machine to a working/ turned on computer? Because the monitor will ALWAYS say "No signal" if it isn't hooked up to anything. Also, you will want to verify that none of your pins (from the end of the cable) is missing, and that your cable is firmly seated into the port on your computer. Other than those things, you really need to say a lot more than just, "The monitor turns on but says 'no signal'" for anyone to be able to assist you.

When i plug up the L1975NW lcd monitor what should show up ?


"no input" means that there is no signal from computer or the monitor cable is unplugged. When you first turn on monitor it usually does a self test and then looks for signal. Not connected to PC will give a no signal. If it is connected but PC is off (not unplugged) then it should go into standby as you vid card will be sending a standby signal to any monitor connected. Sometimes the Plug and Play monitors need to register before it will recognize a standby signal from PC, so plug it up and boot up PC. Then shutdown normally, your monitor should go into standby when the PC shuts down.

When my computer says check signal cable what does it mean?


Your monitor is telling you that it thinks it is not receiving a video signal from the computer. You need to verify which of three components is not working, the computer, the cable, or the monitor.

The first thing to do, obviously, is to check that the cable connecting the computer to monitor is good. You will need some extra components to do the checking. I'm going to assume that the cable is detachable at both ends.
First you can try replacing the cable with different one. If the replacement cable works, then it's the cable.
Secondly, you can try different monitor. If you connect this in place of the first monitor, and it works, it's a faulty monitor (needs repairing or replacing).
Third try a different computer with the original cable and monitor, if it all works it looks like the video on your PC has malfunctioned. (This might also be your conclusion if a system comprising a different cable and monitor fails to work with the original PC)
You might just be able to verify the cable by testing the connectivity of all the wires in the cable with a meter, if you knew the pin out of the cable at both ends.
If you find out the computer is getting a signal out, there could be many causes for that, each having its own solution (or not as the case may be)

My acer monitor p191w will turn on acer logo comes on goes black then a screen comes out saying no signal then turns of light turns yellow ...tried restarting monitor nothing


Connect the monitor to a different computer, to see if the monitor works at all.

Connect a different monitor to your computer, to see if your computer really is "sending" a video-signal through the "data" cable. If not, then either the data-cable or the video-card inside the computer is faulty.

Monitor says "no signal"


try to unplug the blue cable and the power cable, then hold the power button for 3 seconds. Reinsert back the blue cable and the black cable then turn it on.If it is no signal in spite of the CPU turned on, contact AOC with regards to monitor since the power supply is busted inside of it..

Says No Signal but I clearly just pluggd it in and turned it on, and yes my computer is on


The "no signal" message is telling you there is no output from the computer. The output signal switches on the monitor, so if not there, check your cables and connections. If you have another monitor, try connecting it instead, and see if it works.This is an unusual problem, so keep trying. Connect the monitor to another computer, such as a laptop, and see if it works. If the monitor on another computer works, obviously it the first computer. If the first computer works with the second monitor, it's the first monitor.

When i turn my monitor on it goes on and shows the acer logo then says no signal and just goes off and this just happened one day i have never had any other problems with it before


If you monitor shows no signal that means it is not connected to the computer properly and not getting any video signals from the computer. You need to check the vga cable properly Try removing the cable from both ends and and reseat the cable. Try another VGA cable. If you are using a Graphic card make sure the card is connected properly

Out of range


You can try removing signal cable from pc.If it still says "Out of range" most probably main logic card or interface board as it is known in the lcd monitor could be defective.If on the other hand removing the signal cable gives message No signal ,cable not connected,try connecting monitor to another working known pc.If it still doesn't work the interface board in the monitor is defective.
