I turned off all of the lights (something I never do) and set my CUSTOM settings to your "night" viewing settings . . . . just to see what it looks like. Wow . . how do you watch an HD program with such low fL from the TV?? Much of the lowlight details are just not there?? Not complaining but wondering?? The good news is that you will NEVER have IR with those settings!
If you use my Custom settings, make sure that you have your sunglasses on . . .
