Hi My 436 has been running for 343 hrs now, so im looking for changing my settings. I looked back at some old threads from27-10-05 and noticed some ISF settings as follows HDMI, colour-0. contast 34. brightness 0. Pro adjust settings were, dnr off. dre off . Blk level on. cti off. gamma 3. acl off. It was also said that pure cinema was set to adv, but when I try to use this setting the tv says that setting can not be used. Any ideas. Thanks........ Mike.
