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!
Deep
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.
Connectors
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.
Speakers
Like the others, the 49er has two down-firing speakers.
32 inch
32 inches is actually quite big, but compared to the 49 it looks practically Lilliputian.
The underneath
The 32-inch pivots vertically. You're looking at the bottom.
The stand
I like this base design better than Samsung's usual solid disc.
Controls
Cryptic icons
27-inch profile
Connections
All three displays have two USB 3 ports, audio outputs, an HDMI, and a DisplayPort connector. The 49-inch model adds a Mini DisplayPort
Aspect ratio
The 27-inch model (shown here) as well as the 32 have traditional 16:9 aspect ratios.
Bottom
Jointed stand
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.
Power
The two smaller monitors have a power button on the back right.
