Answer 1

It depends what distance you are from the screen and on how good your eyes are.

Put your face right up against your tv or monitor. You should be able to see individual pixels.

Now move back. At some point you won’t be able to see individual pixels any more. At this point a higher resolution telly is of no use to you.

** It’s not quite so simple as higher resolution can be used to make sharper edges that you will notice, even past the point of no longer being able to see the individual dots, but the same idea still applies – back off until you can no longer tell the difference.
