Four feet wide
The 49-inch display, which is 47.2 inches wide, is roughly the size of two typical 16:9 27-inch displays (23.5 inches wide) side-by-side. Sign me up!
Its profile is a little deeper than smaller displays.
Controls and power
Unlike the other displays in the line, the 49 incher has a power button underneath rather than on its back.
Glowy and round
Though it's not as functional as the typical display with square VESA-compatible mount, I think this one looks cooler.
Because it doesn't rotate -- that would be a hoot -- it's harder to access the connectors on the 49-inch model than usual. It's a little disappointing that despite the extra room it doesn't add more USB connectors.
Like the others, the 49er has two down-firing speakers.
32 inches is actually quite big, but compared to the 49 it looks practically Lilliputian.
The 32-inch pivots vertically. You're looking at the bottom.
I like this base design better than Samsung's usual solid disc.
All three displays have two USB 3 ports, audio outputs, an HDMI, and a DisplayPort connector. The 49-inch model adds a Mini DisplayPort
The 27-inch model (shown here) as well as the 32 have traditional 16:9 aspect ratios.
The two smaller display have this very robotic looking articulated stand. The 49 can only move up and down, with the ability to tilt the display a bit.
The two smaller monitors have a power button on the back right.
