Re: input not supported
IT sounds like the monitor got fried.. sometimes if the monitor is in the on position as the power comes back, the monitor gets an unexpected sure which can sometime damage the circuitry. You may be out of luck. You're only other option is to try using the monitor on another computer to see if it's just a weird connection issue.

Acer produces a number of LCD computer monitors. Acer's monitors range from 17 inches to 27 inches. Some monitors offer wide-screen viewing, embedded speakers, high-definition visuals, and various display connection ports. Acer computer monitor problems include common issues such as dead pixels, error messages, and blank screens caused by incorrect connections. Some reviewers have also detected image problems with DVD playback on some models.
"Input Not Supported" Error Message Acer computer monitors such as the G24 may issue an "Input Not Supported" error message when users set the display resolution too high. The G24's maximum display resolution is 1920x1200 with a 60Hz refresh rate. Maximum resolutions vary according to the specific monitor model and according to the capabilities of the computer's video card. b> "Input Out of Range" b> Some Acer computer monitors may report an "Input Out of Range" error message due to incorrectly set monitor refresh rates. Much like the display resolution, each monitor also has specific monitor refresh rates with which it is compatible. Blank Screen or "No Signal" Error b> Like other monitors, Acer computer monitors feature color-coded power indicator lights. If the power indicator light shows green, the contrast or brightness levels may be set too low and should be adjusted via the OnScreen Display. If this does not rid the monitor of a black screen, the monitor may be experiencing hardware failure. The "No Signal" or "Check Cable message" may indicate a problem with the monitor's cable connection with the video card. This error may also appear on a blank screen backdrop if the monitor is plugged into the incorrect port on the computer or if the computer is frozen and needs to be rebooted. Faulty power cords or outlets may cause the screen to be black and to show no power indicator color. b> Image Issues b> Some review sites such as CNET have reported problems with streaking and ghosting during DVD playback on some Acer computer monitors such as the AL1931. (A "ghost" is an identical offset image as the primary or desired image.) Unstable or unclear image issues may be caused by incorrectly programmed VGA timings or incorrectly installed monitor drivers. b> Dead Pixels b> Dead pixels and sub-pixels can cause a variety of display enjoyment problems. Acer will only accept returns on LCD computer monitors that have "more than four (4) defective pixels per million pixels." Further, the central area of the monitor may have no more than one defective pixel. Acer does not differentiate in warranty terms between pixels and sub-pixels. Hope this helps.
this is all i could find from the internet.
You can try a power reset to see if that helps. To do a power reset, unplug the power cable and press and hold the power key for 10 seconds. Then, release the power key and plug the monitor in and attempt to use it. If you are still unable to get a proper display, We would suggest contacting technical support to inquire about warranty repair options. Many of our monitors carry a 3 year warranty, so there is a chance you may still have warranty left.
If you remove the cable from the computer does the gren light change to Amber? Do you have a input button on the monitor?If you do,press it until it selects the correct input sometimes it may change and select the incorrect input.The last thing you may try ,if you listen carefully you may hear a low humming noise coming from the monitor this is will indicate a faulty power supply.If this is so you will have to replace the monitor
I will assume that you have checked out the power cables and external cables. If this is the case you will usually notice an indicator light from your monitor. Universally it is yellow or orange when it has power, then turns green when it detects input from your computer. If the Led light doesn't turn green even when your laptop is already booted, your culprits would be your iMac's video controller or your monitor's input cables.
When your computer is starting up, hit F8 and you'll see the safe mode, safe mode with networking, etc. screen...You should see a choice that says "enable vga mode". Select that and windows will start and the os will select a screen resolution for you. After that, everything will work fine...I hope.
Frontech external Miracle TV tuner not working with LCD(ACER 15") monitor. Error msg "input format not suppoting". But CRT monitor (samsung 14") is working with the same.
Pl give advice email@example.com
OK try booting up in "Safe Mode" Press F8 just after Turn on, when and if ya boot into safe mode then adjust your Video settings to say 1024x768x32bit and then reboot, if all good then when you are at the desktop, then adjust the settings to whatever you require... maybe 1280x1024x32bit.. Ya all good.
If this doesn't work.. try the Monitor on another PC.. see if it works... if it does.. then maybe ya Video card is going/gone "Toes up" if not, then ya got a fault in your monitor, usually some sort of Power Supply problem or the like.
i think the probelem is monitor resolution out of range . try the system resolution changes and connect the monitor then the issue is solved 80% or other problem is monitor hardware damages cheack the whole hardware components
