The 5020 & 6020 doesnt have the same offsets as previous non elite models. This was an issue for some that swayed them to the elites. I highly recommend reading up before attempting any changes in the SM. Search the avs link Adam provided for exacts. See D Nice's night time settings for a good place to start. Day or ambient light viewing will affect settings to much to warrant any use of others ISF settings. You can always pick a cal disk and make adjustments in the home menu.
