Picture pixelation


TV manufacturers know that a certain percentage of TV's will end up with dead pixels. I believe there is an app called UDPixel that can fix dead pixels on monitors and TV's. Google it.

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 monitor is very blue suddenly. Is this the monitor issue and how do I fix it.


That could be the monitor or the video card, or even the cable connecting them.
If the RED signal dies, you are left with green and blue - so everything goes green/blue.
Check the connections at the video card and at the monitor.
Either try another monitor on your computer, or try your monitor on another computer to determine which is at fault if the cable isn't the issue.

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.

I have a nvidia geforce 9500 GT graphics card it has two dvi ports and a s video out i plugged a s video cable in it that has a female connecting end on the other end and u can plug the red and blue and...


It is because when the operating system starts it switches to the resolution, color depth and refresh rate set in the OS. One or more of these settings is not compatible with the TV.
Read your TV manual carefully and find what it supports.
Connect only a computer monitor to your computer, set it to the display settings supported by the TV and shut down.
Connect the computer to your TV, cross you fingers and turn it on.

Good luck!

Computer works for a bit then the whole screen turns to pixels. we bought this pc brand new about 3 months later started showing images pixel up, noe the whole screen turns to pixels..and cant see nothing...


Well, the first thing you can try is replacing the monitor cable or monitor, and that is less expensive. If it still gives you trouble, you may need to see about replacing the video card; there are modestly priced, reliable ones that are relatively easy to install, yourself. I'd recommend installing the new VC after taking out the old one, just because your system will be happier. Then see if after any of these steps, the monitor isn't working better.
If it still presents a problem, it may be an issue with the motherboard, which means basically replacing the whole system, for the cost and time involved, depending on your motherboard.

Monitor Shows pixelated colors then flashes no input and turnsoff


If it is a desktop, try another monitor and see if you're gonna get the same problem. If its a laptop, connect an external monitor to it. If the other monitor shows the same thing, it means to say that there's just something wrong with your video card. If that's the case, you might as well uninstall and reinstall the video driver. If in the other case, the other monitor's fine then definitely its your monitor. if there's a reset button or a factory reset button available on your monitor then reset it. If the same thing happens, get it replaced.

No signal from computer to monitor 8/13/08!


I had the exact same problem!! Drove me crazy for days. Couldn't find any answers online, contacted Gateway tech support and they told me my warranty was expired but they'd be happy to discuss my issue for $2 per minute. Gateway can **** it!!

At first I thought the problem might be a malfunctioning NVIDIA card, a problem with my DVI cable, or the monitor itself. But, after turning off the computer, unplugging the DVI cable, replugging the DVI cable and restarting the computer, I noticed I could get the firmware flash screen to show, including the BIOS menu boot and the Gateway system reinstall screen to show. As soon as the Windows flash logo would display, however, the monitor would drop out and display the dreaded "No Signal" error.
This indicated the problem was a software one and not hardware! The cable, monitor and video card were all working fine. Then I remembered that Windows installed its automatic update a few days prior. In fact...

THE PROBLEM TURNED OUT TO BE A WINDOWS UPDATE INSTALLED A FEW DAYS PRIOR.

After succesfully booting into safe mode (F8 during the flash/bootup screens), I went to Add or Remove programs in the control panel, clicked on the "Show Updates" box on the top, and uninstalled the Windows update from a few days prior to the occurance of the error. After a reboot the problem was solved.

I hope this will help anybody else struggling with this error!
