That was true in Ansel Adams's time, but not today. Today, a display or a camera with more pixels has more resolution (whether you like it or not there are now two separate definitions of the word: - 1) how many distinct details can be perceived and 2) how small are the details that can be perceived)
I was not aware Mr. Adams shot digital, I thought he felt with film grain and that is very, very different form pixel structure.
Resolution comes from the source and is never even to the pixel structure of a sensor. Same goes for the monitor. Between the MTF and Kell Factor the resolution never equals the pixel structure when going from an analog capture to a digital medium and back again.
