Monitor develops lines and quits responding

After about five minutes the monitor develops lines in which you can see the various colored pixels. The keyboard doesn't respond nor does the monitor change. after about 30 seconds the monitor responds to normal. Is this a loose connection or the beginning of the end for this computer?

Have a purple line that runs down the screen on my s27a950d monitor. is there a solution to this?


You can use this pixel test, this test for dead pixels, but it will also help with stuck pixels,move through the colors, look at each color to see if the line remains on each color, then switch between colors as fast as you can, do this at least 5 times cycling through the colors. If this does not help I think you will have to go to the MFG website and check your warranty. If you don't have one or it's expired and you end up buying a new one, make sure you check newegg.com, one of the best places around for computer parts.

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.

Montor has colored lines on left side


Are we talking thin vertical lines that run all the way from the top of the screen to the bottom? If so, this usually indicates a failure of the chip controlling that line of pixels.Unfortunately, there is no easy repair for this and the screen will need to be replaced.

What does it mean by dead cells?


I assume this is related to your LCD monitor.
I think you mean dead pixels. The LCD monitor has tiny pixel elements, one for each red, blue, green color and each one of these colored pixels are turnes on by a transistor. When a transistor fails then the colored pixel it controls does not light up. This is a dead pixel and it shows up as a tiny black dot.
If the screen displays a blue screen, a dead blue pixel will appear as a tiny black dot in the blue screen.
You normally would not notice a few dead pixels unless they are grouped together.

Laptop will boot up but only shows color lines/pixels


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...
