Monitor Problems (maybe something else)

I am currently having problems with multi-colored pixels popping up on my monitor while it is on. The pixels pretty much stay, and more pop up the longer the computer is on. When I drag windows, the pixels create 'lines' on the screen.

Is this a monitor problem, power supply, or video card?

Sound like the video card is at fault,
when it happens , unplug the vga cable ,the monitor should go to a osd menu with or without the pixel,
plug back in to card is it still there or changed ,

sounds like the vga card is getting hot , fan may not be working.

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.

Fuzzy screen on Gateway FPD1975W TFT LCD Monitor


With the pixels acting up and the monitor having the same problem on any computer that its connected to. The screen itself is bad and since there are no replacement screens for that monitor, you would have to buy a new monitor or get it replaced if its under warranty.

Screen is now a weird color


The problem might be in the cable. Try to reconnect it to your machine. Also try to set your color settings on the monitor itself, so that all the colors are equal.

Monitor problem


You didn't specify the card you are running but here is how I would approach the issue.

#1 refurburished Monitors have at a minimum a 90 day warranty, so be prepared to call Dell Tech Support and troubleshoot if my information doesn't help, if the monitor is defective, then they will have to exchange it.

#2 The optimal Resolution is 1680 x 1050 60 hz, you need to ensure that setting (You didn't specify, so I mentioned it)

#3 Sometimes color issues are caused by cabling issues. Try both DVI and VGA connections, see if there is any difference between them (digital or analog, the picture should look the same) If one looks ok, the other doesn't. then it may be a bad cable.

#4 Does the issue occur on more than one system. If it does, then the monitor is bad. If you have individual pixels stuck on (Red, Green or Blue) and you have more than 6, that in itself is justification for replacement.

#5 If all the above doesn't work, contact Dell Tech support for an EXG

Red pixels on the Srceen


Dead or stuck pixels are not uncommon in LCD displays, and the less you pay, the more likely it is to happen (as a general rule) Most manufacturers will a dead pixel warranty, ranging from 7 days to lifetime.

Read your warranty carefully, and speak to the place where you bought your display.

I hope that helps, if you have any further problems, please add them ass comments to this question. If I have been able to answer your question (or not) please click on one of the ratings buttons to let everyone know how I did.

Flickering, sparkeling, ghosting, you name it. Related to electricity in house?


No, it is not the electricity in your house, I had the same problem. Send it back to Samsung and get a new one. I have had to send my monitor back 4 times!

Monitor problem


I have had similar problems. It would appear that the power supply is at fault, not the monitor.
