Wireless GeForce Graphics Card Announced 202

arcticstoat writes "PC gamers who are sick of being constantly distracted by whirring fans could now have a helping hand from a new wireless graphics card. Galaxy sub-brand KFA2 has announced a graphics card with no display outputs. Instead, the KFA2 GTX 460 WHDI uses a wireless link to send the display output from your PC to your screen, whether that's a conventional monitor or the HD TV in your lounge. You just need to attach the bundled receiver to the back of your chosen screen and you're done. With a wireless keyboard and mouse, you could place your PC at the other end of the room, letting you crank up those fans without having to listen to the whirring next to you."

      The article does say that

      The WHDI standard supports HDCP 2.0, so it can route protected content (Blu-ray films, for example) without a problem.

      However, the device outputs uncompressed / unmodified video. This means if the video is protected or encrypted, it will be safe, otherwise you're sending out in the clear.

    • This is the major difference between PC and console gaming. The PC game GUI is designed to be seen from a distance of less than 1m whereas console games are designed to have the player sat well past that distance away from the screen.

      • Saying that, though, I bet for the same price (or a little more) than you'd pay on decent air cooling for your gaming rig + this card, you could water cool the whole thing and have it make less noise than your mouse moving over the desk surface.

        So long as you're taking this into consideration while building the machine, it's probably true. If it's an upgrade then the wireless video card might make more sense. Or, you know, a cooled, filtered, muffled enclosure.

        This is the major difference between PC and console gaming.

        Other differences include 2. cost per player and 3. selection. PC multiplayer is usually LAN or online, and setting up a LAN party is far more expensive than buying extra controllers. In addition, not all developers have the clout to get their games onto the consoles.

    It claims to "intelligently" determine what parts of the frame are important to the eye.... No thanks, I'll prefer the compressed video. I'm not too interested in a compressed compressed video. from the FAQ on

    How does the Video Modem Work? The WHDI video modem takes the uncompressed HD video stream and breaks it into elements of visual importance. The various elements are then mapped onto the wireless channel in a way that gives elements with more visual importance a greater share of the channel resources, i.e. they are transmitted in a more robust manner. Elements that have less visual importance are allocated fewer channel resources. The result of this unique video-modem approach is that any errors in the wireless channel are not noticed as they only affect the less visually important bits. Very high rates of video information can be transmitted because the human eye can tolerate the errors that fall on the less important bits. Traditional wireless technologies (such as WiFi) do not differentiate between the least important and most important information, and thus cannot deliver the bandwidth or robustness of WHDI

    Input lags of over 50ms, here we go!

    • 50ms? When I ping my desktop from my laptop over WiFi the results says 1ms.

      If you use a regular USB mouse, then the polling rate is 125hz or 8ms of input lag. The fastest 1000hz mice are 1ms then. Your video card is also set to render 3 frames ahead by default which can be between 0-50ms there (this can be set to 0 though). And finally, unless you are using a CRT, your LCD probably adds somewhere between 5-50ms of framebuffer input lag.

      I really don't see how 1ms of wireless lag will be noticeable.

        Pinging is all fine and good, but try to transfer a, lets say, 1920x1080, 24bit color frame over WiFi, first with then without compression, then measure how long did that take. Now do 60 frames consecutively. If you can fit it in 1ms, without encryption and even with some form of compression, I'll be very, very impressed, then ask how long since you came from the future.

    If display can be detached from computers, then forget about tablets, notebooks, or even smartphones. You have "the box" somewhere in your house and from any place you can have alternate input and output devices to work with it, you want a tablet? something to work in a desk? Using your tv set? All can have the same computer behind, and you could use the best interface for what you need to do.

    If that becomes portable or wearable, same could go for mobile computing, and you could interact with the IO device you have with you, be smartglasses, something of the size of a phone or a tablet, or even some kind of sixth sense [] technology

    • Yes, this is probably the best use for this technology today; you carry the display and wireless input device(s) and the computer sits in one place. If the display is big enough to sit on a desk but small and light enough to be carried around then you win, otherwise, there is no point.

      I agree that reality overlay is the desired goal; I don't see any reason you couldn't use this technology for a HMD, although for now you're going to need an external pack on a lead.

      The kiosk segment is covered by low cost ultra-portables. All you need is a power cord and you can load the videos via USB or Wifi. And they would not be using your whole available spectrum for video.

    The first thing that came to mind was potential use with a laptop. You could switch from built-in video to this for 3D gaming and use your HDTV for the picture (being that 1080p is as large as almost all laptops ever get anyways).

    Done correctly, you could manage to have a $400 budget laptop for normal use and when you want to play games, sit it on your coffee table, sync it up, and presto. No need to spend $1300 on an Alienware or similar rig.
