    These sponsor Segues are getting smoother each video, Im impressed.

    • Pseudocode

      the only way it would be better is if LTT was actually sponsored by Segway

      Not gonna lie they had me in the first half

    • VanCamelCat

      Actually, not everybody feels that way. Recently, I have been stopping Linus vids mid way because there are waaaaaaaay too many sponsors per video and they are NOT usually done well anymore. That being said, this specific video showed that there's still a chance the sponsor segways will keep being fun like they used to be. Maybe kist lower the quantity and increase the jok quality a bit and people like me will stop skipping them or closing the vids all together because of them.

    hey linuis in the website it says it can do 120 hz PeakDo 4k Station Pro $399.00 $329.00 Application: Extend PC/Mac/Android/iPad audio/video signal to an external HDMI display such as to monitor/projector without wire. Technology: 60Ghz technology loads a massive amount of data from the signal source to display without any process. Spec: Picture Quality: High Resolution Mode: 3840*2160 @ 30Hz Balance Mode: 1920*1080 @ 60Hz "High Refresh Rate Mode: 1920*1080 @ 120Hz" Range: 100ft Latency: less than 1ms response time. Installation: Plug and play, it works the way how traditional HDMI cable works, but wireless

    Linus you should resource a company and make a wireless transmitter for 1080p 120hz

    Of interest if u look on the peakdo website right now the are selling a 4K version and a 4K pro version which has the 1080p 120 ghz display option. Seems they are watching!

      refractive index or most often the dielectric constant. You referred the latency to the velocity factor. It is not right. PLEASE TALK TO SOMEBODY BEFORE YOU SHOOT VIDEOS.


    face it, you don't watch linus tech tips just for the tech tips, but also for the smooth segues

  • AliciaBrownSugar

    Not gonna lie, I liked that segue into your sponsor, haha. Really thought you were gonna show the wireless HDMI adapter.

    like cmon that sponsor, seriously !! i hit the like jus for that he got me this time.

  • Lizardo

  • taiiat

    this has a long way to go for gaming. 1080p120? that's basically budget thesedays. at the cost of this sort of Hardware, the person that's going to be buying it, probably has a Computer that can do 1440p240. so, there's quite a ways to go yet.

  • Travis

    look at a chart of the radio spectrum, see how Fn huge the area is jus the US alone uses, n youll see y products like these arent more plentiful or cheaper, theirs jus not that much spectrum we have access to

    it looks like ur demonstrating how bad 20 year old tech is when u show how easy it is to mess the signal up its still cool tho

    Linus! You are wrong again. Speed of information is the group velocity or the derivative of the dispersion relation. It is not the phase velocity which is directly affected by the refractive index or most often the dielectric constant. You referred the latency to the velocity factor. It is not right. PLEASE TALK TO SOMEBODY BEFORE YOU SHOOT VIDEOS.

    You talk a fair bit of physical interference but next to nada on wireless interference. Which frankly is stupid for one very obvious reason: Multi-monitor setups. Even assuming this is only used for "wireless HDMI" the moment you have two of em in relatively close proximity (as you would with 2-3 monitors) then you're gonna drop bandwidth by interference alone. You already see this with WiSA speakers, Xbox Wireless and standard 5Ghz connections. The phone ain't gonna give a damn, it'll auto-switch to 2.4Ghz if it gets bad enough but your controller or speaker might start dropping like mofos when you're watching 4K video on your phone via the 5Ghz. So no this is never gonna be a replacement for HDMI, even with refinements. It's gonna be a companion which in certain scenarios will be the better choice but otherwise nope.

    They can "disappear" the wire connecting pc & monitor all they want, you still have to plug the monitor into the wall socket. I'd rather have a gaming monitor that was powered through the display cable off the PC's power supply.

    I prefer to stay with wires as much as I can, because it is safer if all that signals run through the wires rather than through my body. Because there is literally NO investigations of how all of these hundreds of our wifi, bluetooth, and other signals going through our body at the same time impacts our overall health DURING THE LIFETIME because all of these technologies are relatively too young to have such statistics, and new wireless technologies appears and release too fast to be completely proved if they are thuly harmless. We need decades of observation to measure it. So better be a little bit old, use good old wires at least on your desktop PC, because you certainly will not regret it if in next 10-20 years medics and scientists operating the 20-30 years of statistics will prove that too many wireless networks over the years will increase a risk of cancer for example, or some other diseases. I better be less mobile but more healthy.

    I think with a few adjustments where the signal is not pinpoint but spreads in a wider range and also imagine if you have a wall mounted HDMI though out your house. I wonder if you could have multiple displays going from once computer?
