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.
I believe the max resolution this LCD can support is 1440 x 900 / 75 Hz. If you set your display resolution higher then that, you will receive the input signal out of range error. Your LDC turns off to protect it self from the invalid settings. If you can not change it back once your PC boots to windows, you may have to do it in save mode by pressing F8 once you power on your PC and before the windows loading screen starts. Regards,Chris
When does the screen go blank? Also what do you have plugged into it this most likely just because your input signal may be set at to high a resolution or frequency. Once I have more information I can assist you further. Thanks, Lee
Ive seen this on other monitors. Look for a 1 and 2. Some monitors do NOT auto detect a signal, and this one might not. Look for a way to set the monitor from Digital input to VGA input. Try that and see.
Its possible that your computer maybe having a driver conflicting with your monitor. My suggestion would be reinstall the software that came with your monitor. If you don't have that go to the companies website that produced the monitor and download the newest monitor drivers. As well for an extra double check, make sure that all wires connected to the monitor and the computer are in place. (might check your monitors energy saving setting)
I suspect the invertor supplying power to the Xenon backlight tubes has failed.
This can be reapired but may not be cost effective.
Ask for a quote from your local computer specialist but keep in mind the cost of a new monitor.
