how many of you have dreamt of a world with no wires
not managed not hidden away just
gone well we've made some progress wireless
keyboards and mice depending on the model are almost indistinguishable from
their tethered brethren wi-fi six is blazing fast under ideal conditions but
wireless displays that can run both at a
high enough resolution and refresh rate for gaming can only be found in unicorn
fantasyland and hey
did you see that i knew it holy crap hold on a second here it is
look at this we finally found it we found the
entrance unicorn fantasy land baby
wait this isn't unicorn fancy land how did this message from our sponsor
get in here ridge wallet bridge mullet has redefined the
traditional wallet with its compact frame and rfid blocking plates keep your

Intel y-die or wireless display technology first launched way back in
2010 and allowed video to be transmitted from your pc to certain hdtvs but while
it was low latency it wasn't anywhere near good enough for competitive gaming
and it got discontinued in favor of miracast anyway like wide-eyed miracast
piggybacks on the same hardware as your device's wi-fi network connection that
means it's fairly ubiquitous these days there's tons of devices that support it
but it also means that both image quality and latency are limited to what
you can do over Wi-Fi so they suck but the game i'm running right
now this ain't no game folks one moment please the game i'm running right now is
at 4k 30 hertz with no compression on
paper that is a whopping six gigabit per
second of raw data that is well beyond the theoretical maximum of even the
latest wi-fi 6 routers and adapters so
how do peak do now i would like to begin by stating
that the company that sent us these wireless HDMI kits has done an excellent
job of trying to look as sketchy as humanly possible their site is nearly
impossible to find unless you google the product's name specifically the logo on
their facebook page looks like it was scaled in ms paint their twitter account
has actually been temporarily restricted and the two reviews of this product on
the official website were not only both posted on exactly the same date
but one of them was even written by the general manager of peak dude amazing
product it really works the same way like HDMI cable that runs in a minute
there's also basically zero technical explanation for how exactly it works
with simple claims of a 60 gigahertz band running at 3.96 gigabit per second
requiring no installation or internet
wow fortunately we're Linus tech tips so we
don't need no stinking specifications and the tech that they're using is
called y gig or 60 gigahertz wireless
now at 4k 30 hertz they are nearing the
7 gigabit per second speed limit of the first generation
802.11 ad which actually led us to
believe that it might this one right here not this one might be a very early
product using the 802.11 a y
second generation y gig standard but given that it was scheduled for a
working group approval in september 2020 and that there have been other products
making similar performance claims since back in 2019 it seems unlikely but i
mean hey 1080p 60 ain't bad let's actually flip
over to this one for a minute to continue our demo
i guess this is a good way for us to demo the simplicity of the setup hey
there we go
is there supposed to be a light on the other one oh bloody hell i plugged it into the
onboard HDMI
30 hertz pretty rough 60 i mean
console kids would have given anything for 60 FPS not that long ago
you know what there's just no other way to put it this is impressive you know
like look ma no lag
oh wow i still can't aim but that's a whole separate issue honestly though
guys i don't expect you to take my word for it i'm hardly a counter-strike pro
but you don't have to because due to a miscommunication with my writer we
actually have an excess of evidence for how well it works we used both our
high-speed camera and NVIDIA's ldap display latency tester to validate
peakdoes claims and if we look at both the average click click-to-photon
latency of the peakdoe and a regular old
copper HDMI cable they are shockingly similar but the impressive thing isn't
the speed at which the data is being
beamed radio waves through air are actually faster than electronic signals
through a wire like as logitech loves bringing up about their light speed
wireless the impressive thing is the seemingly
negligible processing delay like clearly
it's a pretty difficult thing to nail down because most wireless HDMI dongles
that i've tried in the past add 10 or even tens
of milliseconds of latency and this one
it just doesn't of course
that doesn't mean that it's a perfect experience i mean
here's something you can do with a wire
look at that picture perfect around the corner
whereas with the peak dough i mean it's as simple as taking something like
this cute little pillow from ltteststore.com
and well actually no seem to handle that okay okay how
about this water bottle from ltteststore.com
you told me it was going to break it ploof what if i put it in front of the
receiver oh oh there it goes
okay now let's try it let's try the water bottle this is it's a good quality
water bottle let's wireless transmissions right how
is that working why is my hand blocking it and the water bottle oh it needs both
the point is it's fairly easy to stop
now 802.11 a y is supposed to deliver
massive improvements to both range and data rates enabling transmission rates
of 20 to 40 gigabit per second and
ranges in excess of 300 to 500 meters
that is absolutely incredible and could allow 4k
high refresh rate or 8k video transmission but until we see some
actual products it might as well be in unicorn fantasyland the real question
though is if y gig has been around for over a decade and you get basically the
same latency results as you would with one of these why are we still using
cables like cave people this article from pc world called it pretty well back
in 2013 when they said it's not going to replace your wi-fi anytime soon 60
gigahertz wireless has a naturally shorter range than your typical wi-fi so
that mini one we showed you guys only gets to five meters of range and costs
200 us dollars and to get the 25 meter
advertised results of this one which i'm calling the chungus you need high gain
beam forming phased array antennas to boost the power we don't know how much
this one's going to cost in north america because peakdoe is
peak random when it comes to communication
but it does 4k so it's higher bandwidth it has a built-in usb hub with power
delivery so you can single cable dock to your laptop with it and it has the same
negligible latency performance as the other one so i would have said not cheap
except that the pricing you win on what was it like aliexpress or something
uh yeah andy found it for 218 us dollars so i don't know why the other one even
exists anyway let's start walking shall we and see how far we make it okay let's
go on uh flow plane you guys aren't subscribed to Floatplane yet you gotta
get on flow plane there's definitely lots of exclusives lately so go check it
out here let's play an exclusive all right david versus golinas
do we have a tape measure by any chance or are we just winging it ah okay
is this still working i mean this has got to be like 10 meters at this point
how far are we wait yeah 25 meters is pretty far
holy bananes
it's yup it's pretty far away hold on a second still going fine just fine wow
that's freaking awesome like this is really far i see why we uh decided to do
this outside oh no it's working perfectly it's just
the video that stopped oh no i dropped the wi-fi oh
yeah all right fine we'll just here we go
it's still working um
hello can you stop working at some point please
this is a lot of wireless HDMI here
is it dead yet come on
oh there it goes oh that's definitely 25
meters that's nutty i mean no wonder the thing has a fan in the
back to keep the transmitter cool this right
here ladies and gentlemen active cooling on your HDMI cable
kind of wish i could take it apart and see what makes it tick but there
wasn't any obvious way to get it apart without like
damaging it and there's another big disappointment that hopefully peakdoe
can address in the future despite this unit being rated for 4k 30 hertz which
it works great for what it can't do is
1080p 120 hertz even though
theoretically that has the same bandwidth requirements we tried manually
changing display settings for NVIDIA control panel and it tries fails and
reverts back to 60 hertz every time if they could fix that 1080p 120 would make
this easy to recommend for gamers who want to have their tv across the room
from their pc with no wires or have a
projector up in the ceiling without running an HDMI cable lots of things
actually and clearly it can be done the
htc vive pro vr headset runs at a whopping 2880 by
1690 hertz but for whatever reason
pretty much no one has bothered to bring high refresh rate wireless to the
desktop though that isn't the end of the world for pikto there are lots of other
applications that you could use it for like sending a camera signal to a
monitor or when you want crisp and precise demonstrations on a bigger
screen without the hassle of staying plugged in since the latency really does
feel comparable to a cable but there's a huge asterisk and that's the
interruptions or choppiness that we noticed either when obstructing the line
of sight or if the transmitter and receiver aren't aligned very well now
the big 4k unit does improve significantly on the small one but
without knowing the cost of this thing it's hard to recommend simply going out
and buying it it's definitely cool technology though
and that is why we decided to make a video about it
it actually works really well you know what else works
this segue to squarespace squarespace is great no joke we actually use it both
our linusmediagroup.com and ltxexpo.com websites were built quickly using
squarespace and they're super easy to maintain if we need to make quick
changes if you haven't heard already squarespace is an all-in-one platform
that makes it easy to get your website up and running quickly if you have a
home business you definitely need one you can use it to sell things you can
choose from tons of different templates just find the one that makes the most
sense for you and run with it and if you trip while you're running and hit your
face on the ground don't worry squarespace offers webinars a full
series of help guides and you can even contact their 24 7 support team to help
you build your site just go to squarespace.com forward slash LTT and
get 10 off today i mean who knows guys
maybe you've got a perfect use case for something like this i mean it would be
pretty cool to stick a nook or something on the ceiling and just have it transmit
to a monitor for the ultimate wireless setup they've even got battery-powered
monitors you could like trip people out pretty good like there's no computer if
you guys enjoyed this video by the way make sure you check out our our wireless
gaming mice actually faster video because the results might surprise you
