I use a 55" Curved Samsung 4K TV. The DPI is similar to a 24" 1080p in a 2x2 configuration. The curve provides a similar effect to turning 2 monitors toward the viewer. I don't use the height very often, as I have progressive lenses and have to really look up to see the top. But I can lean back for watching a full screen video quite comfortably. IMHO it's fantastic. For those that can still see a difference in Hi-DPI an 8K 55" would be for them. I really don't need it though and this thing costs about $600 at Wallmart.
