If you ever wondered whether you will see a big improvement when going from analog TV to digital and to high definition: the answer is yes.
The difference between analog 480i and digital 480i is simple: all the noise is gone. Picture looks nice and clean on digital. That was expected.
When switching to a channel with 1080i (resp. 720p), details increase a lot. Everything looks crisp. Expected too.
When switching back to digital 480i the picture does not look nice any more. Everything is a bit fuzzy. And going back to analog 480i it is getting close to unwatchable: fuzzy and lots of visible noise. I did not expect this step back to be that harsh.
It’s easy to get spoiled. Did not take more than one afternoon.
