 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 6 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 if, 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 Fantasyland, baby. Wait, this isn't Unicorn Fantasyland. How did this message from our sponsor get in here? Ridge Wallet. Ridge Wallet has redefined the traditional wallet with its compact frame and RFID blocking plates. Keep your wallet bulged down and use offer code LINUS to save 10% and get free worldwide shipping. Intel Y-Di 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 Y-Di, 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 PeakDo. Amazing product. It really works the same way like HDMI cable but wireless. 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 YGIG or 60 gigahertz wireless. Now at 4K 30 Hertz, they are nearing the seven 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 AY, second generation YGIG 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, 1080p60 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? Here we go. Wah. 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 LDAT display latency tester to validate Peek-Doh's claims. And if we look at both the average click-to-photon latency of the Peek-Doh 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. 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 a corner. Whereas with the Peek-Doh, I mean, it's as simple as taking something like this cute little pillow from lttstore.com, and well, actually, no, seemed to handle that okay. Okay, how about this water bottle from lttstore.com? You told me it was gonna 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 a good quality water bottle. Let's wireless transmissions, how is that working? Why is my hand blocking it in the water bottle? Oh, it needs both. The point is it's barely easy to stop. Now, 802.11AY 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 YGIG 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 gonna 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 beamforming phased array antennas to boost the power. We don't know how much this one's gonna cost in North America because peak dough 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 price in you in on what was it like Ali Express or something? 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 a flow plane. You guys aren't subscribed to flow plane 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 Galinus. Do we have a tape measure by any chance or are we just winging it? Oh, okay. Is this still working? I mean, this has gotta be like 10 meters at this point. How far are we? Wait, yeah, 25 meters is pretty far. Holy bananays. It's, yup, it's pretty far away. Hold on a second. Still going fine, just fine. Wow, that's fricking awesome. This is really far. I see why we decided to do this outside. Oh, no, it's working perfectly. It's just the video that stopped. Oh no, I dropped the wifi. Oh, yeah, all right, fine. We'll just, here we go. It's still working. 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 damaging it. And there's another big disappointment that hopefully Peek-Doh 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 through 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 wanna 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 1600, 90 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 Peek-Doh. 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. Actually works really well. You know what else works? This segue to Squarespace. Squarespace is great.
