Have an old 42" plasma which has served me well but is a little long in the tooth. Currently sitting about 7" from the TV. May be rearranging and/or moving in the near future which would lengthen the distance. Have seen the graphs showing I'm currently in the "4K is worth it" territory for a screen of 55" size at my distance. Am between Sony's W800C or Samsung's J6300 for a 55" 1080p, or Sony's X810C for a 4K. Debating whether 60" is worth it for me. Curious as to anyone's thoughts on size, resolution, or models.
