Hi, I thought I would try to do some calibration today after having my set for about a week now. I only have thw NTSC version of Avia so I thought I would try the THX Optimiser on Monsters Inc. While adjusting the constrast usin gthe 8 white boxes even with the constrast on full the boxes did not lose their definition. So my question is, how do you set the constrast? Cheers Paulh.
