Intel Wireless Display: From Your Notebook To The Big Screen

QoS, Protected Media, And Conclusion

Wireless technologies are anything but bulletproof. Many “best-effort” technologies will sacrifice quality as the link degrades. This doesn’t seem to be the case with Wireless Display. Intel recommends using the laptop in the same room as the Netgear adapter, but I was able to walk across the house with the notebook playing Microsoft’s Fighter Pilot clip in HD without losing connectivity or overall quality. What did change was the network utilization, which spiked up to 50%. Simply sitting on the desktop from that range roughly doubles network utilization versus same-room range. This is an example of the headroom Intel built into Wireless Display, should the technology need to cope with range or interference issues.

Protected Media

There’s another rub to take into consideration here. You can play all of the YouTube content, Hulu-based movies, and MP3s you want. But you cannot play content that requires HDCP, including standard DVDs or Blu-ray discs. Wireless Display reports itself to the operating system as an unprotected HDMI port, and given its wireless nature, I can’t imagine the technology ever becoming a protected video path.

Conclusion

I’ll start with what Wireless Display is not. It’s not a replacement for the HTPC you already have in your theater room. It’s not lossless, meaning whatever content you play on your HDTV will not look as good as it did on the notebook. And Wireless Display isn’t completely bulletproof. It relies on a wireless adapter shared between two networks, and it is possible to saturate.

What Wireless Display is, however, is an easy-to-use mainstream capability that you get as a “free” value-add when you buy one of the three notebooks selling at Best Buy (it’s bundled with Dell’s Studio 15z, Sony’s VAIO S-series, and Toshiba’s Satellite E205). Wireless Display is also being enabled by resellers building notebooks on Intel’s Spring Peak platform, which gives you more room to pick the components you want in a laptop. The adapter is available on its own for about $100 bucks, if you want to add other displays to the PAN.

You have to be comfortable with the quality (lossy MPEG-2 compression) and the usage model (fire up a video clip, kick back, and watch). Wireless Display fares amazingly in a conference room, where a presenter can throw PowerPoint up on a projector and flip through slides. It’s also great for home videos or picture slide shows—the big screen sure beats everyone crowded around a little laptop.

HDCP prevents playback of DVD and Blu-ray content, and that’s a real bummer. But I’ve enjoyed using Wireless Display for catching up with the few shows I watch on Hulu, and for families that are only really looking to sit down and watch TV together, this technology is a cool, convenient addition to a current-gen hardware platform that we weren’t expecting when we first took a look at the Mobile Core i5 and Core i3 processors.

    what an epic fail... a locked tech that requires you to use an intel laptop with locked software? arrg!

    I wanted this to stream from my desktop to my TV in the other room. Now they tell me that if I want to buy this I have to buy an intel laptop with their "HD" video (lowest performing video card on the market)

    this sucks.

    getting there, now give me a wireless card for my desktop coupled with an HDMI to wifi plug thing-a-majig to plug into the back of my t.v. so i can do this without buying another computer, adding to my already 5 computers under one roof. honestly, how hard can it be?

    Am I to be expecting to see desktop monitors all with wireless connection in another 6 months??? ;0

    But good idea... now I can take my 55" TV to my bathroom! xD

    Seems like a nice bonus, but not a real viable option because of all the restrictions. With some nice improvements, this could be a cool technology.

    I still prefer my Kodak HD MediaServer I picked up for $50 on woot. Streams anything I want from my media server (dvd and bluray if I choose) either wireless or hard line and is connected to my TV via HDMI. Picture so good I cant complain although it did take some tweaking of my network to run smooth. Had to reposition my wireless router to be more central in home. Stupid cheap ass Verizon ActionTek router sucks so I may upgrade to a new router soon.

    Best $50 I ever spent.

    Besides the already mentioned locked tech in Intel laptops, it only has 2-channel audio? That's definitely not what I have in mind when I think of "Home Theater" at all. No thanks.

    It is interesting tech. Too bad it is tied to intel's crappy integrated gfx.

    The 0.5 second delay kills any usefulness. (Visible at 2:40 in the video). Useless for gaming, useless for webrowsing or office apps - anything that requires mouse-screen coordination.

    Only useful for watching vids (assuming the sound is encoded and sent with the video).

    Crap, I saw that too and I passed on it. I now regret it because I can't find a cheap HD media player for that price anywhere now!

    Correct, and that's something I harp on several times in the piece. This is *only* useful for those folks who'll be watching video (and yes, on page two the encode/decode process is described in more detail--it's an MPEG-2 stream).

    I don't think this technology holds much for now. Maybe in the future when cheaper laptops can easily output 1080p over wireless.

    All this device seems good for is watching hulu and giving slide shows...which begs the question why not just use cables directly attached to the TV? So many Blu Ray players have Pandora, Youtube, and Netflix. It is only a matter of time before they get Hulu.

    It just seems too costly for its limited to use. For the extra cost of a laptop capable of even producing and streaming bluray or HD content (which this thing cant even do), you could buy or build a cheap HTPC - Case Closed!

    I have been using this for wireless audio and video to my HDTV for a while and it's awesome without the limitations of "just your notebook". Just plug the usb in and you're good to go on any pc/notebook. Only prob is that you'll have to wait for the next gen to get 1080p. Intel's version is probably more refined/newer though?

    If you have a large, distributed office where the presenting employees all have these laptops, and all conference rooms have these netgear devices, and there are a lot of presentations going on, this might be useful. But even the syncing would be a nuisance because you'd have to sync up each time you entered a different conf room.

    I like the Win 7 "push to" concept better. If I can find a screen as easily as I can find a printer (assuming IT has made that process easy), and I can push to that screen as easily as I could print to a printer, that would be good for presenting. Otherwise, I'll stick to a VGA connector.

    To be fair, the benefit of Wireless Display would be that it's a feature being enabled on compatible notebooks "free of charge." It's debatable whether the inclusion of Netgear's adapter is driving up the price of Core i5/i3 notebooks, but even if the full cost of the device is wrapped into the total cost, it's still $100 vs. $179 for the Warpia setup. Best-case scenario, it's a value-add for the folks buying these notebooks. More than anything, for me, it's interesting to know *how* the technology works, where its strengths lie, and identifying it's clear and present limitations!

    I do not understand the need for this device. Just buy simple media player (CinemaTube, O!Play and etc) plug it to the TV and stream video. That's all

    If you can get it for "free" with your notebook purchase, why would you buy the media player, though? =)
