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.
If you get the same thing with an externe monitor then your Video card is dead. sometimes it's separate from the motherboard, if it's the case it might cost you 150 USD to replace it (used on ebay). If not sell it for parts... Cheers
Try putting on an external monitor, if the external monitor stays on while the laptop lid goes out, your laptop monitor (lid) is going out (yes it happens quite a bit).
If the external monitor goes off also, Check all your power settings and video settings for the laptop (power setting can be found with the screensaver section of the desktop settings) - if all that is as it should be - it means it is your video card, and since the video card is mounted (intigrated) on the motherboard, there is not much more to do than replace the motherboard or get a new laptop.
This is the issue with the monitor.This is a hardware issue.Please connect the notebook to external monitor and check .If it is working fine then it is the issue with the LCD of notebook
If not then this is the issue with the video card.
And ckeck the power cables tooi think this is the issue with the monitor of the notebookAny how you can try to install the latest version of video drivers
