Acer AL 1912 (black) resolution issue

Intermitten resolution problem. When the monitor first turns on, colors and resolution are fine. After a while (no definite, fixed timeframe) images change into an almost photo negative look. Areas that should be dark or shadowed are now white or magenta with vertical black bars running through them. Sometimes it corrects itself, especially if we close IE or windows that were open and leave just the desktop is showing. Sometimes turning the monitor off for a while and then back on works for a bit. Looking to solve a problem With my ACER AL1912. T first it runs normal and after a few minutes its starts to turn grainy and greenish color. Sometimes it also gets a dying effect of slowly fading to dark with a vertical strip near the middle or sometimes ofset to the right. it will come and go. I've check all wiring and nothing seems to help. I've even installed a new video card for gaming purposes. and tried other dvi cables to see if it was an issue. Problem still persists. Any help would be good. Not wanting to take the monitor apart if necessary.

[u][b]LCD Monitor Shadow Effect[/b][/u]
This problem is best described as the LCD monitor "Shadow Effect".
The solution to this very simple. No software or hard ware changes required.
The cables that are connected to the LCD monitors are causing the problem. Its also called as electromagnetic noise or electrical noise.
[u][b]Solution: [/b][/u]Keep the two cables - (power cable and moitor display cable), that are connected to the LCD monitor as far away as possible with each other and also away from other electrical cables.
Thats it. Your shadow effect is fixed.
Thank you.

Sansui no signal


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.

Friend,
On the monitor go to settings and shift the screen to the left till the display is correct. However, please check for other resolutions after you have shifted. May be the monitor is not geared up to take on 1280 X 1024. Check that as well.

Check your connections to the PC. Make sure that they are nice and secure. If there is a resolution problem setting it should display the boot process and then go blank after starting the operating system.

Screen Goes Blank


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.
