VidyoPanorama displays and that the equipment rack should be within 15 ft. (4.57 m) of the displays (if you
want to avoid using cable extenders).
Display Size
So now that you have an idea of the room size you need, what size should you select for your displays?
Vidyo recommends that you select at least a 50" display, but if you often have more than four participants in
a conference, displays measuring 60" to 65" provide the best experience. Vidyo also recommends using
LCD displays. LCD displays are generally superior to plasma displays; they weigh less and use less energy.
The following table provides general guidelines for viewing distances for various display sizes:
16:9 Display
Diagonal Screen Size
50"
55"
60"
65"
Note that in many cases the acceptable viewing distance is much farther than the recommended seating
distance. For example, a 65 in. display can be viewed up to 16.3 ft. (4.96 m) away, which is beyond our 7 ft.
(2.13 m) to 12 ft. (3.66 m) ideal seating range. However, the extra distance allows an additional row of
people to see the displays. These additional meeting participants may not appear full-size at the remote
locations, but they will be able to see and participate in the conference.
To make it easier for you to visualize a room, let's use an example. Suppose you have six 55" displays and
you want to mount them on one wall with a credenza below them. You will need a wall that's at least 15'-3"
(4.64 m) wide and 8'-10¾" (2.70 m) high to accommodate the credenza and displays (as well as the camera
and speakers):
In a typical conference room, you will have a table, chairs, and perhaps some collaboration tools, such as a
whiteboard and a ceiling-mounted visualizer. You should leave enough space behind the participants for
them to move their chairs out from the table as well as walk behind the table. You also need to leave room
for the door. Therefore, our room with the six 55" displays would require a minimum 14 ft. ¾" (4.28 m) room
depth and 21 ft. (6.40 m) room width as you can see here:
Recommended Viewing Distance
6.3 ft. – 12.5 ft. (1.92 m – 3.81 m)
6.9 ft. – 12.8 ft. (2.10 m – 3.90 m)
7.5 ft. – 15.0 ft. (2.28 m – 4.57 m)
8.1 ft. – 16.3 ft. (2.46 m – 4.96 m)
