Easy, although I find myself having to
reboot my router.
I use this at home with my iPad.
No experience with this at work, but
we will implement.
Latency is good to great, meaning
high motion video is acceptable.
$100 for Apple TV + Apple Device

Perhaps the most platform agnostic
solution. Small applets that are quickly
installed are available through…
Any OS – Android, iOS, Windows.

Chrome, IE, Safari.
Expensive: $1300
Personal experience:
Incredibly easy for the end user.
Limited to bench testing, but worked
extremely well.
Setup is a little more involved in that it
does not have a wireless NIC, but rather
connects by Ethernet to the wireless

Screencast AV by Belkin
Nothing to install on the PC. This is a virtual
HDMI cable.
Latency is outstanding. High motion video is
This solution is a transmitter that one connects
to the HDMI port of their PC, and a receiver
that one connects to the flat-screen display.
The transmitter requires power.
Super easy for anybody that is capable of
connecting an HDMI cable.
Reminder: HDMI only.
The transmitter has four HDMI inputs, meaning
that if you have a display lacking enough inputs
then this solves your problem.
This solution operates completely
independently of the NIC or WiFi.

$35 it is dirt cheap and it
includes a 6 ft. HDMI cable.

Avior Wireless HD Kit by IOGear
This is another transmitter\receiver solution.
Accepts wide variety of inputs – e.g. HDMI, VGA, DVI (with DVI to VGA adapter),
separate audio pins.
Outputs include component and S-Video, which are particularly useful for connecting
to a projector.
The transmitter will broadcast to as many as four receivers.
Nothing to install.
Not subject to wireless NIC or wireless network issues.
Calls to the help desk “I’ve connected to the thing-a-majig with the grey cable, and
pushed the button until the HDMI…”
Cost is $450-ish.
May be in limited supply.
Requires power for the transmitter.
+ Miracast
is wireless multimedia streaming standard
promulgated by the Wi-Fi alliance.
+ There are many recievers that claim Miracast compliance.
+ Results vary… widely.
Some devices simply never accept the connection – e.g. my Toshiba
Symbio Blu-Ray player.
Some devices accept connections from Android devices – e.g. my
Panasonic Blu-Ray BDT330 player.
One device accepts connections from Android and Windows devices –
you’ll have to wait for the next slide.
+ The
holy grail… a Blu-Ray player with quality Miracast. Until
+ Microsoft’s impending dongle is a Miracast device.
Push2TV by NetGear
Works really well with Android and
Windows 8.1.
Lists at about $60.
Smaller than a deck of cards, but much
Draws power through a USB port,
meaning that if your flat panel has a USB
port you can piggy back the power for the
Push2TV device off of the TV.
Firmware makes a big difference, check
and update the firmware.
Latency is meh. High motion video and
people subject to motion sickness are a
bad mix.
It is dependent on the wireless NIC. If
there are any problems with the wireless
NIC then they might make themselves

advice: Avoid loading up
any Wi-Di drivers that don’t
land on your device by way
of automatic updates.
Additional Wi-Di drivers seem
to muck up the wireless NIC
in my experience.
