Hoping to replace current 46" Sony KDL-HX750 with a 55" 1080p HDTV. Not interested in investing in Ultra 4K because of the need for a new AVR, cables, etc.. When Ultra 4K becomes mainstream I will go for quality not low end. Since that is some time away I choose to stay with 1080p. Please recommend your choice of the best 55" 1080p.
