Bad Pixels in a TFT are small white dots on the screen caused by broken pixels. Means you could have a bad LCD. _________________ Owner & Administrator

ok, I was just wondering that, because I was at my friends house, and there were a bunch of little white pixils dancing around the screen.
Thanks! |

Perhaps you mean the Tango? Ratataa!
If they seem to be moving around the screen, you have a videocard problem. But if they are staying in one place and flickering, it will be the TFT. _________________ Owner & Administrator

an FYI for those others that wonder about the number of dead pixels deemed "acceptable.
T.H. did a piece on the issue, and the one thing to keep in mind is to verify the class or rating of the Monitor prior to purchase.
| Quote: | The standard also defines four levels of quality. Class 1, the highest, allows no defects at all. Class 4, the lowest, allows up to 262! Fortunately nobody refers to it. Apart from some exceptions, all manufacturers refer to Class 2. If they do not specify, the monitor is Class 1 by default and you can have it changed at the smallest pixel defect.
The standard distinguishes four types of defective pixel.
Type 1: number of always-lit pixels.
Type 2: number of always-unlit pixels.
Type 3: other defects, particularly on sub-pixels and the RGB cells making up pixels (lit or unlit). This means red, green and blue pixels lit the whole time. Experience shows that this is undoubtedly the most common defect.
To find the total number of defective pixels allowed, add up the defects of Types 1, 2 and 3.
Type 4 (Fault Cluster): the number of defective pixels in a square of 5 x 5 pixels on a panel.
Lastly, the standard stipulates the number of errors allowed per million pixels on the panel. More dead pixels are allowed on a 17" screen than on a 15" one. |

| One stuck sub-pixel is very common for 19" LCD's, right? I have one blue sub-pixel that is always "off" - but I only noticed it after running one of those test programs. From what I gather, if all I have is one dead sub-pixel on my monitor, I made out like a banshee luck-wise. |
