Although LED and Plasma TVs are there in the market, but one can still see that the market of LCD TVs and monitors. If you are planning to buy a new or may be a second hand LCD monitor or TV, it is very necessary for you to check if there are any dead pixels.
In this little post, you would find a way by which you can check if that particular LCD is in perfect condition or not. Since these ways would use a nifty tool, you can easily put them to practice if you are testing LCD monitors. If you want to try them out on LCD TVs, then see if you can connect them to your computer, so that you can make use of these ways.
What Is A Dead Pixel?
Before we actually get into finding dead pixels, I would like you to understand what exactly a dead pixel is. And other names used for it. If we are talking about a 1080p LCD screen, then it would have 1920 pixels horizontally and 1080 pixels. And that’s some number, right? Finding one or few imperfect pixels out of them is definitely a huge task.
But if you can make use of the below mentioned ways, then finding dead (imperfect) pixels won’t be a huge task. These defective pixels are also known as stuck pixels, dark pixels or dark spots.
One thing you need to check is the rules set by the manufacturer. Some manufacturers treat it as a replacement issue only if it has more than 4 dead pixels (one meant for each corner). Just get those things sorted out and go for a replacement.
How To Find Dead Pixels Of LCD Monitor Or TV
Its a pretty simple service to check the dead pixels. And the fact that you need not install any thing to use this service makes it a pretty good option. All you need to do is get on to this service, choose the color. It has 9 colors, and just by using your arrow keys, you can change the colors and see if any of the pixels is defective. Its pretty simple!
This is a freeware (not a web service) which is actually a ready to use program (does not require you to do any installation). All you need to do is launch this program and see if any part of your display screen shows weird colors. Its homepage is pretty explanatory and I do not think you will really need any help because its all about spotting dark / strange spots on your display, which won’t be very difficult.
There are more number of such services like LCD DeadPixel Test, but the fact that all of them are the same i.e. check for defective pixels on different colors.
Once you find any dead pixels, do check the manufacturer policy to see if those many number of dead pixels would make that monitor / TV eligible to get replaced.
Good Luck!
