remember what a big deal cordless phones were in the 80s and 90s
well it wasn't too long before engineers expanded this untethering idea to other
gadgets so nowadays we've got 2.4 gigahertz gaming headsets bluetooth
christmas lights and enough lte signals flying through the air to make any
passing extraterrestrials think that we communicate solely through some kind of
primitive form of hieroglyphics but one modern device has lagged behind
the others in this era of wireless keyboards wireless mice and wireless
networking our monitors seem to be the
one thing that still needs a long clunky
cable running across the desk so what gives
well for starters this observation isn't completely true there are wireless
display standards that have been around for quite some time and i'm not talking
about features like casting where your
phone or your device just sends an instruction over wi-fi for your tv to
access a youtube video or whatever i'm talking about real ways to connect a
display and have it show anything you'd like just as you would with the wired
monitor that might be sitting on your desk right now
one currently popular option is miracast
this is essentially an HDMI connection over wi-fi that works if you're using a
computer or other device that has wi-fi built in
the nice thing about miracast is that it doesn't need to go through a router
rather it forms a direct connection from your computer to your display so you can
use it even if your wireless network is slow or if there isn't one available at
all in Windows 10 simply click connect in the action center and that will cause
your system to scan for available miracast displays click the one you'd
like to connect to and you are all set
in theory although there are displays with
miracast baked in as well as HDMI adapters that enable it miracast isn't
compatible with everything Android devices dropped support for it some time
ago mac and iOS users instead have to use airplay which by the way does
require a proper wi-fi network and for devices without wi-fi at all like a
desktop pc well no luck there either
so if you want some more flexibility you might want to look at a standalone
wireless display kit that lets you plug an HDMI connected transmitter into your
pc or your source device even a camera for example and an HDMI receiver to your
display these devices often use standards that
transmit data quickly enough to avoid the huge loss NVIDIA quality through
compression that can be a big problem with wi-fi based solutions
so then with all those benefits and both miracast and standalone kits even
supporting 5.1 surround audio just like
a physical HDMI cable why aren't we all using them right now well it turns out
you're gonna run into issues no matter which wireless display implementation
you choose even if you go for a low compression non-wi-fi solution because
wireless connections are nearly always slower than their wired counterparts and
wireless display tech is no exception it's more difficult for these signals to
carry the higher amounts of data needed for a high-res picture so want 4k well
get ready to spend a lot of money if you can find something at all
and of course we haven't even gotten to the elephant in the room the slow
elephant in the room lag because these compressed wireless
signals require extra processing at both ends you'll probably experience more
latency with a wireless display this means that you'll have small delays when
you do anything like move your mouse or type a sentence which might be fine for
writing an email or giving a powerpoint presentation but it can be so bad as to
cause desync issues with video playback and it's almost guaranteed to be a
killer for gaming making matters worse many wireless HDMI
kits perform best over very short distances and with a direct line of
sight between your source device and your display making them once you factor
in that you have to run a power cord to them anyway so you're not going full
wireless actually a lot more work to set up than
you might have initially imagined so then unless you really need a display
in a spot where you just can't run accord to it i wouldn't bother investing
money in extra equipment to make your setup wireless
for now besides this gives you an opportunity to
practice good cable management which i know is everyone's favorite part of
setting up their battle station do you find yourself racing against the
clock as a freelancer it's challenging but thanks to the internet there's never
