create 3D; but when they're merged so as to be viewable on a standard video monitor, there may be smearing of the pixels.
2. Wireless monitors
Wireless technology has been very slow to take off, probably because
some of the earlier wireless displays operated on a narrow band
between 4.9 and 5.9 GHz, which is in the frequency range of many
other electronic devices, including mobile phones. That resulted in
lots of interference, and so hospitals and ASCs shied away.
New wireless video monitors for medical purposes now operate
between 3.1 and 4.8 GHz, which avoids interference between video
displays and other equipment in the OR. However, these systems tend
to have a 30-foot (10-meter) range — and chances are, you have more
than 1 OR within that kind of range. This means there may be interference if you use wireless displays in several abutting ORs. As such, I'm
not aware of any facilities that have employed wireless displays in all
their ORs. The biggest advantage, though, is a crucial one: Wireless
video monitors get cables off the floor.
A small caution: To transmit the signal wirelessly over the available
bandwidth, images will be compressed somewhat. It might not be significant in practice, but it's inevitable that there will be some degradation in the quality of video displayed.
