We've got a 52" Samsung LCD in the den and 40" sets in 2 of the bedrooms. All 3 sets are 1080p, 120Hz and they all produce very nice, clear pictures. The den has 3 large windows and even with the bright sunlight the picture is still good.
I wanted another set for the family room downstairs so I went out on Friday and bought another Samsung with the same features.
I don't watch much TV myself and seldom, if ever watch sports, but these 4 Samsungs seem really good and offer everything I need.
The nature shows in HD are incredible.
