1
00:00:00,080 --> 00:00:08,639
how many of you have dreamt of a world with no wires

2
00:00:04,240 --> 00:00:10,080
not managed not hidden away just

3
00:00:08,639 --> 00:00:14,400
gone well we've made some progress wireless

4
00:00:12,960 --> 00:00:18,240
keyboards and mice depending on the model are almost indistinguishable from

5
00:00:16,080 --> 00:00:24,800
their tethered brethren wi-fi six is blazing fast under ideal conditions but

6
00:00:20,880 --> 00:00:27,119
wireless displays that can run both at a

7
00:00:24,800 --> 00:00:32,719
high enough resolution and refresh rate for gaming can only be found in unicorn

8
00:00:30,400 --> 00:00:36,399
fantasyland and hey

9
00:00:33,840 --> 00:00:40,800
did you see that i knew it holy crap hold on a second here it is

10
00:00:39,440 --> 00:00:46,640
look at this we finally found it we found the

11
00:00:42,640 --> 00:00:49,600
entrance unicorn fantasy land baby

12
00:00:46,640 --> 00:00:53,440
wait this isn't unicorn fancy land how did this message from our sponsor

13
00:00:51,199 --> 00:00:56,719
get in here ridge wallet bridge mullet has redefined the

14
00:00:55,199 --> 00:01:00,399
traditional wallet with its compact frame and rfid blocking plates keep your

15
00:00:58,879 --> 00:01:04,879
wallet bulge down and use offer code Linus to save 10 and get free worldwide

16
00:01:02,559 --> 00:01:04,879
shipping

17
00:01:11,760 --> 00:01:19,119
Intel y-die or wireless display technology first launched way back in

18
00:01:16,479 --> 00:01:25,360
2010 and allowed video to be transmitted from your pc to certain hdtvs but while

19
00:01:22,640 --> 00:01:29,439
it was low latency it wasn't anywhere near good enough for competitive gaming

20
00:01:27,520 --> 00:01:34,640
and it got discontinued in favor of miracast anyway like wide-eyed miracast

21
00:01:32,560 --> 00:01:39,439
piggybacks on the same hardware as your device's wi-fi network connection that

22
00:01:36,720 --> 00:01:43,600
means it's fairly ubiquitous these days there's tons of devices that support it

23
00:01:41,840 --> 00:01:48,799
but it also means that both image quality and latency are limited to what

24
00:01:46,159 --> 00:01:52,640
you can do over Wi-Fi so they suck but the game i'm running right

25
00:01:51,759 --> 00:02:01,119
now this ain't no game folks one moment please the game i'm running right now is

26
00:01:57,119 --> 00:02:04,479
at 4k 30 hertz with no compression on

27
00:02:01,119 --> 00:02:07,040
paper that is a whopping six gigabit per

28
00:02:04,479 --> 00:02:13,200
second of raw data that is well beyond the theoretical maximum of even the

29
00:02:08,640 --> 00:02:14,480
latest wi-fi 6 routers and adapters so

30
00:02:13,200 --> 00:02:19,599
how do peak do now i would like to begin by stating

31
00:02:17,840 --> 00:02:24,720
that the company that sent us these wireless HDMI kits has done an excellent

32
00:02:22,319 --> 00:02:29,280
job of trying to look as sketchy as humanly possible their site is nearly

33
00:02:27,280 --> 00:02:33,040
impossible to find unless you google the product's name specifically the logo on

34
00:02:31,680 --> 00:02:38,319
their facebook page looks like it was scaled in ms paint their twitter account

35
00:02:35,360 --> 00:02:42,720
has actually been temporarily restricted and the two reviews of this product on

36
00:02:40,720 --> 00:02:47,680
the official website were not only both posted on exactly the same date

37
00:02:45,680 --> 00:02:50,959
but one of them was even written by the general manager of peak dude amazing

38
00:02:49,760 --> 00:02:56,080
product it really works the same way like HDMI cable that runs in a minute

39
00:02:53,200 --> 00:03:01,120
there's also basically zero technical explanation for how exactly it works

40
00:02:58,400 --> 00:03:07,599
with simple claims of a 60 gigahertz band running at 3.96 gigabit per second

41
00:03:03,680 --> 00:03:08,720
requiring no installation or internet

42
00:03:07,599 --> 00:03:14,000
wow fortunately we're Linus tech tips so we

43
00:03:11,599 --> 00:03:19,120
don't need no stinking specifications and the tech that they're using is

44
00:03:15,599 --> 00:03:22,239
called y gig or 60 gigahertz wireless

45
00:03:19,120 --> 00:03:24,400
now at 4k 30 hertz they are nearing the

46
00:03:22,239 --> 00:03:29,360
7 gigabit per second speed limit of the first generation

47
00:03:25,799 --> 00:03:31,360
802.11 ad which actually led us to

48
00:03:29,360 --> 00:03:37,519
believe that it might this one right here not this one might be a very early

49
00:03:34,080 --> 00:03:40,159
product using the 802.11 a y

50
00:03:37,519 --> 00:03:43,840
second generation y gig standard but given that it was scheduled for a

51
00:03:41,519 --> 00:03:47,519
working group approval in september 2020 and that there have been other products

52
00:03:45,680 --> 00:03:52,319
making similar performance claims since back in 2019 it seems unlikely but i

53
00:03:51,200 --> 00:03:56,319
mean hey 1080p 60 ain't bad let's actually flip

54
00:03:55,120 --> 00:03:59,599
over to this one for a minute to continue our demo

55
00:03:58,159 --> 00:04:05,120
i guess this is a good way for us to demo the simplicity of the setup hey

56
00:04:02,640 --> 00:04:05,120
there we go

57
00:04:07,519 --> 00:04:14,760
is there supposed to be a light on the other one oh bloody hell i plugged it into the

58
00:04:11,200 --> 00:04:14,760
onboard HDMI

59
00:04:16,160 --> 00:04:20,959
30 hertz pretty rough 60 i mean

60
00:04:19,600 --> 00:04:25,120
console kids would have given anything for 60 FPS not that long ago

61
00:04:23,840 --> 00:04:28,560
you know what there's just no other way to put it this is impressive you know

62
00:04:26,880 --> 00:04:32,240
like look ma no lag

63
00:04:30,479 --> 00:04:36,000
oh wow i still can't aim but that's a whole separate issue honestly though

64
00:04:34,160 --> 00:04:40,080
guys i don't expect you to take my word for it i'm hardly a counter-strike pro

65
00:04:38,080 --> 00:04:43,919
but you don't have to because due to a miscommunication with my writer we

66
00:04:41,600 --> 00:04:48,960
actually have an excess of evidence for how well it works we used both our

67
00:04:46,160 --> 00:04:54,080
high-speed camera and NVIDIA's ldap display latency tester to validate

68
00:04:51,440 --> 00:04:58,960
peakdoes claims and if we look at both the average click click-to-photon

69
00:04:55,680 --> 00:05:01,919
latency of the peakdoe and a regular old

70
00:04:58,960 --> 00:05:07,759
copper HDMI cable they are shockingly similar but the impressive thing isn't

71
00:05:04,560 --> 00:05:10,240
the speed at which the data is being

72
00:05:07,759 --> 00:05:15,120
beamed radio waves through air are actually faster than electronic signals

73
00:05:12,800 --> 00:05:17,280
through a wire like as logitech loves bringing up about their light speed

74
00:05:16,320 --> 00:05:22,880
wireless the impressive thing is the seemingly

75
00:05:19,759 --> 00:05:24,320
negligible processing delay like clearly

76
00:05:22,880 --> 00:05:29,360
it's a pretty difficult thing to nail down because most wireless HDMI dongles

77
00:05:26,720 --> 00:05:33,919
that i've tried in the past add 10 or even tens

78
00:05:30,880 --> 00:05:35,280
of milliseconds of latency and this one

79
00:05:33,919 --> 00:05:39,919
it just doesn't of course

80
00:05:37,440 --> 00:05:45,520
that doesn't mean that it's a perfect experience i mean

81
00:05:41,840 --> 00:05:45,520
here's something you can do with a wire

82
00:05:46,479 --> 00:05:53,199
look at that picture perfect around the corner

83
00:05:50,320 --> 00:05:56,479
whereas with the peak dough i mean it's as simple as taking something like

84
00:05:55,039 --> 00:06:00,800
this cute little pillow from ltteststore.com

85
00:05:58,479 --> 00:06:03,919
and well actually no seem to handle that okay okay how

86
00:06:02,319 --> 00:06:06,919
about this water bottle from ltteststore.com

87
00:06:09,039 --> 00:06:13,860
you told me it was going to break it ploof what if i put it in front of the

88
00:06:13,039 --> 00:06:19,280
receiver oh oh there it goes

89
00:06:17,759 --> 00:06:22,400
okay now let's try it let's try the water bottle this is it's a good quality

90
00:06:21,039 --> 00:06:27,600
water bottle let's wireless transmissions right how

91
00:06:25,199 --> 00:06:31,759
is that working why is my hand blocking it and the water bottle oh it needs both

92
00:06:29,840 --> 00:06:34,520
the point is it's fairly easy to stop

93
00:06:33,520 --> 00:06:40,560
now 802.11 a y is supposed to deliver

94
00:06:38,319 --> 00:06:45,840
massive improvements to both range and data rates enabling transmission rates

95
00:06:42,400 --> 00:06:49,440
of 20 to 40 gigabit per second and

96
00:06:45,840 --> 00:06:50,400
ranges in excess of 300 to 500 meters

97
00:06:49,440 --> 00:06:56,160
that is absolutely incredible and could allow 4k

98
00:06:53,599 --> 00:07:00,160
high refresh rate or 8k video transmission but until we see some

99
00:06:57,919 --> 00:07:04,880
actual products it might as well be in unicorn fantasyland the real question

100
00:07:02,639 --> 00:07:08,560
though is if y gig has been around for over a decade and you get basically the

101
00:07:06,960 --> 00:07:13,759
same latency results as you would with one of these why are we still using

102
00:07:10,880 --> 00:07:18,720
cables like cave people this article from pc world called it pretty well back

103
00:07:16,000 --> 00:07:23,599
in 2013 when they said it's not going to replace your wi-fi anytime soon 60

104
00:07:21,759 --> 00:07:27,919
gigahertz wireless has a naturally shorter range than your typical wi-fi so

105
00:07:25,680 --> 00:07:33,919
that mini one we showed you guys only gets to five meters of range and costs

106
00:07:30,400 --> 00:07:36,160
200 us dollars and to get the 25 meter

107
00:07:33,919 --> 00:07:40,479
advertised results of this one which i'm calling the chungus you need high gain

108
00:07:38,639 --> 00:07:44,000
beam forming phased array antennas to boost the power we don't know how much

109
00:07:42,800 --> 00:07:47,039
this one's going to cost in north america because peakdoe is

110
00:07:46,240 --> 00:07:52,160
peak random when it comes to communication

111
00:07:49,759 --> 00:07:56,400
but it does 4k so it's higher bandwidth it has a built-in usb hub with power

112
00:07:54,240 --> 00:08:01,919
delivery so you can single cable dock to your laptop with it and it has the same

113
00:07:59,440 --> 00:08:06,879
negligible latency performance as the other one so i would have said not cheap

114
00:08:04,720 --> 00:08:12,240
except that the pricing you win on what was it like aliexpress or something

115
00:08:09,360 --> 00:08:16,080
uh yeah andy found it for 218 us dollars so i don't know why the other one even

116
00:08:13,440 --> 00:08:20,240
exists anyway let's start walking shall we and see how far we make it okay let's

117
00:08:17,919 --> 00:08:24,080
go on uh flow plane you guys aren't subscribed to Floatplane yet you gotta

118
00:08:21,759 --> 00:08:28,560
get on flow plane there's definitely lots of exclusives lately so go check it

119
00:08:26,000 --> 00:08:33,200
out here let's play an exclusive all right david versus golinas

120
00:08:31,599 --> 00:08:38,399
do we have a tape measure by any chance or are we just winging it ah okay

121
00:08:36,080 --> 00:08:43,440
is this still working i mean this has got to be like 10 meters at this point

122
00:08:40,800 --> 00:08:47,680
how far are we wait yeah 25 meters is pretty far

123
00:08:44,640 --> 00:08:50,000
holy bananes

124
00:08:47,680 --> 00:08:54,880
it's yup it's pretty far away hold on a second still going fine just fine wow

125
00:08:52,959 --> 00:08:59,920
that's freaking awesome like this is really far i see why we uh decided to do

126
00:08:57,839 --> 00:09:04,560
this outside oh no it's working perfectly it's just

127
00:09:02,240 --> 00:09:09,279
the video that stopped oh no i dropped the wi-fi oh

128
00:09:07,040 --> 00:09:14,320
yeah all right fine we'll just here we go

129
00:09:10,399 --> 00:09:14,320
it's still working um

130
00:09:14,560 --> 00:09:21,279
hello can you stop working at some point please

131
00:09:18,000 --> 00:09:24,880
this is a lot of wireless HDMI here

132
00:09:21,279 --> 00:09:24,880
is it dead yet come on

133
00:09:25,279 --> 00:09:30,399
oh there it goes oh that's definitely 25

134
00:09:28,640 --> 00:09:33,120
meters that's nutty i mean no wonder the thing has a fan in the

135
00:09:32,320 --> 00:09:38,000
back to keep the transmitter cool this right

136
00:09:35,440 --> 00:09:41,839
here ladies and gentlemen active cooling on your HDMI cable

137
00:09:40,080 --> 00:09:45,760
kind of wish i could take it apart and see what makes it tick but there

138
00:09:43,760 --> 00:09:50,000
wasn't any obvious way to get it apart without like

139
00:09:47,440 --> 00:09:53,920
damaging it and there's another big disappointment that hopefully peakdoe

140
00:09:51,680 --> 00:10:01,120
can address in the future despite this unit being rated for 4k 30 hertz which

141
00:09:57,519 --> 00:10:04,240
it works great for what it can't do is

142
00:10:01,120 --> 00:10:06,640
1080p 120 hertz even though

143
00:10:04,240 --> 00:10:10,720
theoretically that has the same bandwidth requirements we tried manually

144
00:10:09,279 --> 00:10:16,720
changing display settings for NVIDIA control panel and it tries fails and

145
00:10:13,920 --> 00:10:21,360
reverts back to 60 hertz every time if they could fix that 1080p 120 would make

146
00:10:19,279 --> 00:10:26,320
this easy to recommend for gamers who want to have their tv across the room

147
00:10:22,880 --> 00:10:28,480
from their pc with no wires or have a

148
00:10:26,320 --> 00:10:34,240
projector up in the ceiling without running an HDMI cable lots of things

149
00:10:30,959 --> 00:10:36,800
actually and clearly it can be done the

150
00:10:34,240 --> 00:10:41,839
htc vive pro vr headset runs at a whopping 2880 by

151
00:10:38,600 --> 00:10:43,680
1690 hertz but for whatever reason

152
00:10:41,839 --> 00:10:47,839
pretty much no one has bothered to bring high refresh rate wireless to the

153
00:10:45,440 --> 00:10:51,920
desktop though that isn't the end of the world for pikto there are lots of other

154
00:10:50,399 --> 00:10:55,920
applications that you could use it for like sending a camera signal to a

155
00:10:53,600 --> 00:10:59,680
monitor or when you want crisp and precise demonstrations on a bigger

156
00:10:58,240 --> 00:11:04,399
screen without the hassle of staying plugged in since the latency really does

157
00:11:02,079 --> 00:11:08,720
feel comparable to a cable but there's a huge asterisk and that's the

158
00:11:06,800 --> 00:11:13,120
interruptions or choppiness that we noticed either when obstructing the line

159
00:11:11,120 --> 00:11:19,040
of sight or if the transmitter and receiver aren't aligned very well now

160
00:11:16,079 --> 00:11:22,800
the big 4k unit does improve significantly on the small one but

161
00:11:21,279 --> 00:11:26,320
without knowing the cost of this thing it's hard to recommend simply going out

162
00:11:25,040 --> 00:11:30,000
and buying it it's definitely cool technology though

163
00:11:28,560 --> 00:11:33,920
and that is why we decided to make a video about it

164
00:11:31,680 --> 00:11:38,000
it actually works really well you know what else works
