Tip & How-To about Acer AL2216W LCD Monitor

Acer AL2216W DVI not working after connecting to a laptop

I have had an issue on 3 separate occasions where 3 separate Acer monitors would give me a no signal error after being plugged into a laptop. I have found that taking them apart, and then unplugging the main power line from the power supply to the mainboard seems to correct this issue. It may be some kind of power spike that causes this. I am not really sure though. just thought I would post something about it since I couldn't find any posts about the same issue but it has happened to me 3 times. Figured someone out there might find this helpful.

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.

my acer aspire t180 give one error code beep (which is repeated) no signal to the monitor, and I just take of the ram and cleaned but still with the problem


your desktop graphics chip may be faulty. Please plug your monitor to another system to check whether it shows. If it got signal on the monitor then problem is in your system

monitor not working it lights up and says acer then it says no signal and goes blank


There are two common reasons for that problem. 1) Your video card on your pc may be having issues. 2) Your monitor is not working properly
Here is a test to isolate the problem to the monitor. Plug it into another pc or laptop VGA or DVI slot and try to power it on again. If it works then you know for sure it's your video card giving trouble. Either gone bad or needs the drivers to be updated/uninstalled and reinstalled.
If it doesn't work then you're looking at some monitor repair or potentially a new one. However since you said you saw the Acer logo, it's a positive sign it's not really your monitor as it would not work all together if it had an issue.

Acer X1700 won't connect to monitor; monitor doesn't get signal from computer.


Is the monitor getting power? Does the power button light up? Check all your connections. Power from wall to monitor. Video cable from PC to Monitor. Do you have another computer or laptop you can try plugging into the monitor? If two machines don't work on the same monitor, it's either the monitor or the video cable itself.
Hope this helps! If so, please give a rating!
