It is telling you that it is not getting the video signal from your PC video card. Did you trythis monitor with another PC yet? This monitor has 3 years warranty so please find out if it is still under warranty first before we open it up to look inside. Are also using DVI to VGA adapter?

My acer is no signal.why


To help you troubleshoot no signal issue on monitor, please make sure monitor power cable and VGA cable are connected properly from both end of the cables.

If issue persists, make sure you reconnected to the same graphics output. Some PCs have a connector (or connectors) for graphics on the mainboard and another connector (or connectors) on a discrete graphics card.
You could try swapping the Monitor, Cable, then Graphics over for good ones if feasible.

If issue persists, it is suggested to contact Acer Support Center from the link given below:

Monitor stopped working - says No signal


Hi Paul,

This problem is often the result of a loose video cable connection on the computer or an incorrect video signal selection. Most monitors use a cable with "VGA" connector on the end that mates to the computer video port. Other modern computers make use of an HDMI (like the ones used to connect a TV to a BluRay Disk player) or DVI connector instead - either way if it is loose you will get the same "No Signal" message on screen. Make sure these connectors are making good contact with the port on the computer by seating them fully (or better yet - remove and reinsert). In the case of the VGA connector, most have two screws to hold them in the port - you should make sure both are threaded all the way in. You do not need to crank them down, finger-tight is more than enough.

Many newer - flat screen types in particular - do not have the video cable permanently attached. Instead, they use the same cord and connector arrangement found on the computer. It is possible that the connector has become loosened on the monitor end - especially if the monitor is moved / adjusted frequently. You should check the connections at the rear of the monitor just as you checked at the computer, too.

When satisfied that the connections at the computer and monitor are good, check the monitor again. If the message is still present, the monitor may be able to select between an analog input and a digital input via a menu item accessible from the monitor. Check your monitor manual for instructions to change inputs if unsure. If you are using the "standard VGA cable" (the one with the two screws) you should select the analog input. If you're using an HDMI cable, you should select the digital input. If you're using an DVI connector the input may be either analog or digital. When making a change, wait 5 to 10 seconds between toggling between the analog / digital selections to allow the monitor to sync the signal for proper display.

If you're still unable to display the desktop, it is possible that that someone has changed the BIOS options to select a different video card (if more than one is installed) or that the cable is defective.

I hope this helps and good luck!

How to solve "signal cable disconnect" error?


Do you mean the video cable?
If so remove the video cable/connector from the computer and reconnect it and tighten the locking screws.
If the monitor also have a video connector do the same with this connector.
Boot up your computer and if you still get this error message then the video cable maybe faulty. Try a different video cable and if the problem still not resolved then the problem maybe the video card.

The Hannspree monitor shows start-up along with my computer monitor,but once it gets on desktop, the Hannspree monitor says "no signal input check video cable", but all the cables are connected...


If you have more than one monitor connection it may be outputting the signal to the other connector.

Try booting into safe mode ( tap F8 key untill the menu shows, use the arrow key and enter to select)

if all goes well restart the computer and monitor should work.

No signal message on your LCD monitor screen means that your monitor is not receiving any signal from your PC graphic card. This problem "no signal" have nothing to do with the drivers installations. Have you check whether your graphic card is faulty or your cable connection properly connected/secured? ie VGA (D-sub). As far as I know there are no parallel connectors for PC Monitor connectors only, VGA(D-sub), DVI or HDMI cable interface.

Try to connect your monitor to another PC, just to test whether the LCD monitor is functional.

Hope it helps.

that means your monitor is working fine, just check your video connection on both ends of the monitor and PC.

It shows "check signal cable",


Hi, Hopefully you are seeing this error on the screen of your monitor. If that is the case,
do the following steps.
1 Shut down the computer. To do this, without looking at the monitor, hold the on/off button to your computer in for about 5 seconds. The computer should then shut down.
2 Shut off the monitor.
3 Unplug the video signal cable, the thick one that goes between between the computer and the monitor and then re-insert it observing not to bend any pins. There are two end screws that you will have to be loosened, although they may have not been tightened in the first place. When you reinsert the cable, hand tighten those screws.
4 If there is a similar connector on the back of the monitor, repeat step # 3.
5 Make sure that the signal cable is firmly attached to both the computer and the monitor. 5 Turn on the computer and see if it has solved the problem.
If it does not, examine the cable for signs of damage along it's length.
If it is damaged, replace it. you should be able to get a cable for stores like Best Buy, or possible from a friends old stack of cables.
Hope this helps,
Mark
