After years of reading this forum, this thread finally got me to join and reply.
I'm on my second Panny plasma. I purchased my newest one in late Sept (a 55ST50). My older one is 5 years old. I babied that one until 750+ hours before I dared think about gaming. I only had one instance of IR from a HUD. It went away after about a week. After the 1000 hour mark it saw heavy gaming sessions. IR was never an issue. Yes, I have run white screens to check.
Enter my new Panny. I've babied the heck out of it too. I will until I hit the 1000 hour mark. I zoom in to get rid of station logos, black bars, you name it. But on the other hand, I've run DNice's settings since the hundred hour mark. They don't have the contrast all the way down or anything of that nature. At about 750 hours now - and after pushing hard to get there - I had my first gaming session this week. It handled 12+ hour days of nonstop static white HUDS without the slightest IR - Assassin's Creed Huds for those of you wondering.
Now, at the moment, I do have IR from the game but it is my fault. My last night of gaming, during a mission with low lighting I switched off my original custom setting to the factory gaming mode. It is a torch. Other times when I've switched, I switched back as soon as the mission was done. This time I forgot for about 5 hours. This time I did get IR. At first it was pretty noticeable. After going through the same freakout I had 5 years ago, I decided on a course of action.
The scrolling bar did nothing to eradicate it. Regular tv watching was helping but it was slow going. In the end I went with running a Pixar movie on a loop. After about 20 hours of constant play the IR has reduced by about 75%. I expect it will be gone by tomorrow. Will I game again? Oh yes. But I won't leave it in torch mode again. Up until that point it had no problems. Once I hit 1000 hours, I will stop worrying about station logos and the like.
Would I buy the Panny again? Absolutely.
For those that say why baby it? Most people I know baby their high dollar much loved items when they're new. I don't see how a TV is any different. For pity's sake, people buy 600 dollar smart phones that are super slim and then put them in a massive otterbox complete with a thick plastic coating over the glass out of fear of them being scratched or dropped. That's considered being smart. Doing what you can to limit problems - such as with plasmas - is being just as smart to my way of thinking.
