I have a Toshiba 42HDX82 HD capable RPTV. Lot's of adjsutments possible
I am the one doing the adjsuting and my husband gets annoyed sometimes.
I researched and bought the thing, I know how it is supposed to look, so I am always trying to make it look the best. He did not do any of the research so he has no idea that it can be any better through adjustment than any analog TV could, so he does not understand why so many adjustments are necessary.
Your wife will get it only when you take the time show her the difference. Do this some time other than when a movie she wants to watch right now is on. Show her how to make adjustments so she can make what she watches when you are not there look good too. Explain why programming on each channel will be different every time. Explain about DVD's and how each director shoots movies differently and about aspect ratio's and such.
Also, learn to decide when it matters to adjsut and when it does not, and back off a little if you can.
Good luck,
Dee
