I just received a 65VT60 yesterday that I ordered through Amazon. I was not really planning to purchase a new TV to replace my existing Panasonic 54G10 which I love. I had planned to go 2 more years and then upgrade to a larger plasma. However, with the recent significant price drops on the VT series and Panasonic stopping production of Plasma televisions, I did not want to miss out and have regrets later.
I've read a lot of posts here in AVS about the new series of Panasonic plasmas having extreme IR or burn-in. The one general trend I find surprising is the very high contrast settings that I see being posted here and in other threads. When I got my first plasma in 2009 every piece of advice I read said to immediately reduce the contrast to 50 or lower for the first few hundred hours. I ran that G10 set initially at a contrast setting of 38 for approximately the first 300 hours of use. I even watched some 4:3 content (not much though) and played video games during that span. I never had any significant, long-lasting IR. Only very temporary IR on occasion that went away very quickly when switching to different content. I had Chad B come and calibrate that television when it had roughly 350 hours on it, and even after doing the full calibration my contrast setting was (and still is) only set at 56, and it looks superb. To this day I have played video games on that set for extended time periods (GTA 5 recently) and have watched NFL football all day on Sundays, and I have never had an IR problem.
Now, I do have the TV in a fairly darkened, light-controlled room so I don't need the image that bright or super-punchy to be able to comfortably view it. Others who have the TV in brighter rooms probably need to have a higher-contrast setting. Maybe I just got lucky with that panel too, and obviously the VT60 series are different plasmas from my older G10. It just appears to me that many folks are running their contrast extremely high, which by everything I have ever read contributes significantly to causing IR/burn-in. I immediately put my VT60 in THX cinema mode and dropped the contrast down to 38 and kept the brightness at 50. I then ran the VT60 yesterday for several hours, including a little 4:3 content, stations w/ logos, and played some video games with my son. I looked for IR and never saw any, even when I ran the screen wiper looking for it in the white background. It's still early, but I plan to do the same thing with this panel that I did with the G10, which is to keep the contrast down around 40 for the first few hundred hours, and then get it professionally calibrated sometime next spring.
