frequently as needed.
Also if you can get into the set's service menu there is an aging function that allows you to select from a variety of built-in test screens including a full white screen and the scrolling white bar as well. There you can leave it running indefinitely, whereas the standard scrolling white bar function times out after 15-20 minutes.
So it has a feature to prevent Image retention but you guys claim that image Retention isn't a problem....Seriously??
I will say that I have IR problems with my LCD TV but its an older model(2008) and it is a Proscan (read this as a cheap TV.)
The problem is said to be much less likely on LCDs from what I have read in my extensive searching about my own issues with IR. What LCDs Don't suffer from and this should be pointed out to people considering buying a plasma.....Burn in(which I am sure is as unlikely for a plasma to get as getting an LCD with IR problems) The potential for burn-in(no matter how small) scares me away from plasma. My colors might become slightly off on a greyish screen for a day or two sometimes BUT it can't be permanently burned into my screen (unless I left the same image on for maybe 10,000 hours or something like in a business setting(billboards and such). and my LCD while it may be old(1080i Model) The picture is Gorgeous.
My ultimate point is IR should be a MAJOR consideration for a normal user. I actually have had to turn my brightness and contrast down slightly to keep the problem to a minimum, the result of which is being unable to use my TV to the fullest. Does it matter that these TVs have the brightest brights and the darkest darks if you can't safely use it to its full potential.
If you only watch movies on disk with no logos then for sure completely ignore the potential problem IR poses. Otherwise take some time do you research and make sure you get a brand that has a low occurence of IR.
The picture can be a 100 on a scale of 1 to 10 but if there are after images and crap all over the place trust me its gonna stop looking sexy.
Since discovering the IR issues in my TV I have had to greatly alter my viewing habits, I have to constantly think about what is on my screen and it really takes away from the joy of having a beautiful HDTV. If you are a normal user who plays video games too long, watches cable, note that both styles of TVs have this potential(more likely with plasma) and that it can really get away from just enjoying your set.
This post is not to say that this is an issue for these TVs as I do not own one,(however the fact that features have been included to treat it or prevent it definitely lead me to believe its an issue) the point of my post is to stop you guys from claiming IR doesn't happen. It is a concern for both LCD and Plasma TVs.
EDIT: One thing of note however:
LCD screens basically have 0 chance of Image persistence(LCD equivalent of IR) when they are new and the chance increases with age. Plus side is I don't have to do anything special with my TV to fix it(all white image will make it go away a lot quicker though) it will go away with the tv off.
Apparently for Plasma it is the opposite and the chance goes down with time (From what I have read on this thread) but if you get it you must spend hours or days running content intended to get rid of the problem(if you can at all.)Edited by Will Frommelt - 9/6/12 at 2:17am
