Quick question about the settings, I've had my panel for a week now and have left the settings all quite low as suggested when it was installed, but when is the best time to start to tweak the settings? I heard that after 200 hours viewing was the best, which brings me onto my next question. How do you find out the hours the plasma has been running, I believe that there is a facility in the menu to display this but I can't find it, is it possibly in the service menu? I'd appreciate any help with this and any pointers as to how other forum members have there 435 settings. Al.
