In order to prevent multiple threads asking the same question, please post all questions concerning WirelessHD/SiBEAM here.

Thanks.

Before posting, reference this post:

WiHD on the other hand is also a technology to stream data from the laptop to your TV. It is made by a whole bunch of electronic companies, and it is a direct competitor to Intel`s solution, which is? Yes WiDi (Do not forget this now). WiHD is also available for Bluray players, Cameras, audio equipment to stream data to TVs wireless, not just from laptops to TV.
Ok that said, the requirements for this technology is:
You need a transmitter AND a reciever. According to the manual and the part list, M17x R3 will later have the option to add-on a SiBEAM WiHD card which acts as the transmitter. It is not included today. Here is a video of a guy testing it out
YouTube - Alienware M17x WiHD Demonstration
Anyhow, you can buy WiHD kits to be able to stream data from the laptop to the TV for those who do not have add-ons like the WiHD card. Here there are several options available. From big boxes to small USB plugs. Here is a few kit examples:
IOGEAR Wireless HD Kit GWAV8141K Review
IOGEAR - GUWAVKIT2 - Wireless HD Computer to TV Kit
The first one supports video streaming up to 1080p while the last one only up to 720p. Some new HDTVs today have an integrated reciever so you won`t need a reciever, only a transmitter. Probably the benefit of having many big electronic companies working together to incorporate this technology.
With WIHD you can also do other stuff with your laptop while streaming data to the TV.

The difference between WiDi and WiHD is that WiDi use the Intel wireless cards to transmit the data from the laptop to the TV, while WIHD use a transmitter to transfer the data.

For those looking for part#'s for the Wireless HD (if you did not order the system with it),

Ah, cool.

I thought I duped something in the M18x forum.

Any chance of a merging of the old scattered stuff to this thread?

[BatBoy]

Merging will kill the timeline of the thread. Just go ahead and re-post. No worries. I'm still debating if each should have their own thread based on model. Thoughts welcome.

im confused so what exactly is SiBEAM ?

Yeah, I know about all that. Can certainly be confusing for a board with this many members.

Thanks!

This should be cool for now. Unless there is some kind of difference that isn't obvious.

Ok i thought i might as well post this now

Its been confirmed that the M14x has the wireless HD slot under the battery it also has 2 antennas running from that.. Can some one from the UK Confirm that the British M14x has this slot as well with the 2 antennas

ok correct me if im wrong here. But sandy bridge proc + intel wifi card = 1080p wireless transmission with that push2tv adapter.

So why spend 300 dollars on this when the laptop can already wirelessly transfer video?

Does the built in intel version have a lot more then the 10ms input lag?
Does it not work with the wireless internet active at the same time?

Basically what are the benefits of spending 300 for this wireless hd when intel already supplies wireless hd?

[HerrKaputt]

I'm very interested in seeing what this technology can offer.

Every new AW owner who posts their experience on this will get +rep from me

there is lag i have both the Push2tv 1000 and Push2tv 2000 the 2000 has less lag than the first but you sure wont want to do much in the way of gaming. Not that the intel gpu is much of power house in the 3d department. I have not attempted 3d but i dont see why it wouldn't work the lag is a barrier for sure.

I have watched high bit rate h264 video over the 2000 at 1080p have have not noticed any lag in the video. The 2000 at least lets you do extended desktop while the 1000 only does display mirroring.

I have to honest i never expected it to work room to room but it it does. I hear the Sibeam has to have line of sight.

Widi took a hell of alot of jimming to work on a fresh windows install. It really only wanted to work in intel only mode with no ati drivers loaded at all. It was bloody hell trying to keep switchable graphics working and have the Widi outputting video.

Oh btw you can still use wifi while using WiDi. Even dual band (ie 5ghz push2tv + 2.4 wireless)
