had my gt30 for a while now so fully run in although the picture quality is great i have always found the picture a bit dull until i turned this system on and now has given me a very bright and vivid picture to which i like all i would like to know will this setting give me any issues with image retention or reduce the lifespan of the panel because of the more dynamic picture obviously i like the way the picture is but if it is going to cause any issues with the tv in the future then i may have to think about not using it
