Thanks for your reply.
Actually i went to LG showroom yesterday night and saw 3D tvs also.. they showed me one plasma tv of 42inch which was amazing.. what a 3d quality..
today i did research on plasma tvs and found that they have one big problem of "Burn in"!
Can you please tell me about it more?
I also noted that plasma tvs are cheaper than LEDs!! please let me know some more info on this.. Reply appreciated.
^ burn in means using a device in a particular way so that it can "settle" in its best performance mode.
think of it like this :
you have a knife, but its slightly dull. you use it with a knife sharpener (you are "burning in" the sharpened of a knife so that it becomes more sharp)
now, you have a better performing knife.
however, in your case, the performance of the will not get worse with performance; the "burn in" is permanent.
burn-in is very subjective... you might not notice much change, or you might get a large boost in performance... depends on what unit you get.
I believe there seems to be a slight misunderstanding of the terms. There are 3 terms you should be aware of with TVs, particularly with Plasmas: Break-in, Burn-in, and Image Retention
What Doomgiver is describing is not burn-in, rather it is break-in. When you first get a plasma screen, you must "break-in" your TV. That generally involves leaving the TV on for several hours a day for a total of anywhere from 100-200 hours to let the phosphors (it's what makes each pixel give off light) settle-in. Essentially, the picture that you see when you first get your plasma screen will not be the same picture you will see 100-200 hours later. The fresh phosphors generally burn brighter when you first get the TV (thus distorting the image quality a bit), but lower down to normal levels as you use your plasma TV continuously. After the break-in period, the picture quality will not change. Note that you can even "break-in" an LCD TV.
Burn-in and image retention, on the other hand, are potential problems with plasmas. They both occur when a static image (whether on a part of a screen like the HUD for an FPS or the full screen when you leave your TV on pause) is left on the screen for an extended period of time and that static image can be seen even after the image changes. So if there was a big PAUSE sign on the TV for a long time, even after you un-pause the movie, you will see a faint PAUSE sign on the TV. This typically happens if you leave static images on the screen without properly breaking-in your plasma TV. The difference between a burn-in and image retention is that burn-ins are permanent, whereas image retention will go away over time. Fortunately, burn-ins are not very common with modern plasma screens -- they were big problems for the first generation of plasma TVs. Image retention, on the other hand, is still very common with plasmas. Fortunately, all plasma TV these days come with a program to "wash out" the image retention. Depending on the severity of the image retention, it can take anywhere from a few hours to a few weeks for it go away fully.
I hope this clears everything up! If you have any more questions, let me know!
LG WRman Sherlock, out!
