KFA2 Announces Cable-Free Graphics Card

KFA2 Announces Cable-Free Graphics Card

With no need for display cables, this card could enable you to remove the noisy PC from your desk.

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 ‘WHDI’ part of the card’s name comes from the fact that it uses Amimon’s wireless technology – WHDI stands for Wireless Home Digital Interface.

The standard uses the 40MHz channel of the unlicensed 5GHz radio frequency band to deliver uncompressed 1080p video at 60Hz wirelessly. The card uses five aerials, which KFA2 says will provide ‘the most robust and highest quality HD wireless connection for in-room and multi-room applications.

WHDI has a range of 30m (around 100ft for those still working in Imperial), and can work through obstacles and walls. This, says KFA2, provides a ‘hassle-free way to connect sources anywhere within a room or enable multiple connections.’ The WHDI standard supports HDCP 2.0, so it can route protected content (Blu-ray films, for example) without a problem.

Aside from having aerials rather than display outputs, the card is a typical GeForce GTX 460 1GB affair. It supports Nvidia’s PhysX and CUDA technologies, and it's DirectX 11-compatible.

At the same time, KFA2 has also announced its single-slot GeFore GTX 460 1GB card, the GTX 460 Razor. This card also boasts the typical clock speeds, despite its single-slot cooler. The GPU runs at 675MHz (with the 336 stream processors operating at twice that rate), while the 1GB of GDDR5 memory runs at 900MHz (3.6GHz effective).

Both cards are due to be on sale soon throughout Europe, and both are backed by a two-year warranty.

Are you intrigued by the possibilities of a clutter-free desk for your gaming kit, or are you just salivating at the thought of squeezing a battery of GTX 460 Razor cards into your folding farm? Let us know in the forums.

A long HDMI cable and wireless mouse/keyboard is cheaper i guess

Will wait for range and lag (if any) info, before getting one but very very tempted for my media pc setup!!
Pilgrim72 12th January 2011, 12:36 Quote
*If it works* it could be good to see this wireless technology in a smaller spec graphics card, such as one that might be used for media playback and light internet use. Since decent media pc cases are quite expensive, being able to hide a larger and cheaper case somewhere else in the house could be a definite advantage.

Again though, I would need some pretty solid guarantees about the performance before risking the viewing experience on wireless. Does it have a cable backup or is it wireless only?
Pilgrim72 12th January 2011, 12:38 Quote
Just seen Obiwan's post - and I gotta agree. I bought a 5m HDMI cable from Amazon for £3.50 delivered and it delivers fantastic quality and is long enough to be hidden away and the pc tower to be almost in another room. Perhaps this card will mainly interest those peoploe who still think you need to spend £60 upward to get an HDMI cable longer than 6 inches!

:o)

i'd rather this WHDI setup was sold as an add on, that way it could be used one any pc with a graphics output on it, even laptops. That would be awesome.

Only problem with the media pc thing is getting the remote receiver somewhat near the tv.

Great idea. Lag could be a problem for an HTPC as synchronising it with the sound from the speakers may be tricky. Would be nice to see this sold as an add on though rather than an all-in-one card.
schmidtbag 12th January 2011, 13:23 Quote
this is a really great idea, however, wouldn't there be a slight lag in the frame rate? also you would need wireless speakers, but some people who have surround sound would be all set for that anyway.
maverik-sg1 12th January 2011, 13:28 Quote
The whole WHDI interface is appealing, for gamers I guess subject to lag, but it offers alternative media streaming around the house - just take the TV dongle and your wireless keyboard to any TV.

I guess the limitation will be the keyboard/mouse range versus the WHDI.

excellent company KFA2 :D found my new fav graphics card company since BFG quit, incidentally, it's all the same group of people based in Wales.


think of the possibilities: desktop gaming PC upstairs, TV downstairs. want to watch something that's on your computer? no problem, tune in to wireless signals of your PC, and use your phone to VNC into your computer to control mouse+keyboard.

it would be a fantastic secondary PhysX card. that have side function of beaming video to your TV.
tozsam 12th January 2011, 13:42 Quote
This would be perfect for my HTPC as I use a projector in the livingroom which is suspended from the ceiling, so using HDMI cables (as I do at the moment) means they are impossible to hide without chasing strips out of the wall then replastering with the cable inside.
l3v1ck 12th January 2011, 13:51 Quote
That would be sweet. The noise reduction potential is awesome.
All they need now is a remote on/off switch for the PC.
GRE66 12th January 2011, 13:52 Quote
A novel idea based on a decent GPU but will it be reliable and constant? Can the receivers be baught seperately? Would be nice to have a central PC that could boost the graphics on a lap top or lower spec pc.Would this work? What sort of price? I also noticed an IPhone in the picture, will it be compatible with mobiles,android and Iphone etc?

The 460GTX Razer will be epic for the folders.

Cupboard 12th January 2011, 14:13 Quote
I don't see the issue with lag for an HTPC. It is HDMI, so the lag with affect both the audio and video feeds. Plug it in to a receiver near the TV and you're fine.
Unknownsock 12th January 2011, 14:24 Quote
This would be awesome for casually gaming in my living room, rather having to move my massive tower everytime..

Although I'd prefer to see this as a stand alone unit. Also depends on the speccs.

It shouldnt only transmit HD but a usb 2.0 signal aswell, that would be awesome...
Kingsley813 12th January 2011, 14:38 Quote
Just perfect. Because I do a lot of arch-vis, I rely a lot on networked rendering. This would allow me to keep all my monitors in the same room, and just stack the PC's in the spare room together, without excessive space. And of course, the CUDA capability is useful, as there are not many (good) render engines which use the OpenCL language, leaving my 5870 idle....

All round, quite interesting!!

Multiple Screens? Would be good to have a multi screen option that would share the same connection.

Yeah, lag is the only thing I'm worried about here. However, for a HTPC build, this could be perfection in the making. Only gaming would really suffer from lag.

Not at all. It's for anyone who wants to be able to stick their computer case completely out of view or even out of the same room they are working in (say in a closet). Perfect for a HTPC where you don't want the added noise of fans in the same room you are watching a movie in as well. Don't take such a limited view on this idea. It really is much more useful than you think.

It could be useful for people like me that use a long HDMI cable to watch films and play games using my HDTV as second monitor, or to stream movies to another room.

Wireless? That's convenient for people who want to spy on your computer screen.
[USRF]Obiwan 12th January 2011, 15:45 Quote
HTPC? I have a Xtreamer for that. Small, noiseless, power friendly and plays anything i throw at it. It can be used wireless and through lan. So there goes the overkill HTPC use for this card out of the window.

I can try it for my game pc but since my living room is 7x5meters I think its pointless. And a HDMI wire would be more then adequate. And playing games I strongly believe it will lag a few milliseconds. Besides that my Game PC is very quite (Water cooled) So there goes the second use for this card out of the window.

In the end its all gimmick but not actually usefull. For less money you could buy a Xtreamer /playon whatever lowcost mediaplayer for "htpc" use pland 10meters of hdmi cable if you want tay some games.

You may have a room thats 20 meters long but i wonder if the range of the wireless mouse/keyboard would reach that.

Good point! Will there be some built in hardware encryption between the card and receiver?

Wouldn't it just use WPA2 like every other wireless device?

I wonder why you can't get fibre optic nodes for broadcasting video? The bandwidth that'd represent would be huge, also it'll be free from interference and allow cable runs of several kilometres. In case you ever needed to place your computer in the next town :p

because, my little OpAmp (your avatar) they would be really expensive.

there are long and expensive HDMI cables that claim to be fibre inside, but why buy them if you can go wireless for cheaper?

Has anyone else done the maths of this?

1920 pixels wide * 1080 pixels high * 60 fps * 24 bit colour = 3Gbit/sec

3Gbit/40MHz = 75 bits/second/Hz

That's an insane spectral efficiency.

HDMI sockets don't have fibre channel transceivers in, so that sounds suspect. Unless there's something moulded into the plug ends?
Andy Mc 12th January 2011, 19:27 Quote
So whats the input lag between the card and the screen like then? As I can only really see this benifiting a media PC/tv PC and not a gaming PC.
Picarro 12th January 2011, 19:49 Quote
Oh man. I'd throw this in my pc and place it in the server room. It would be awesome to have a totally clean screen + kb/mouse combo hanging on the wall with a small table. Appeals to my nordic sense of design .. :D



Edit: Just a thought - how does this differentiate from having a wireless HDMI transmitter coupled to your graphics card HDMI output, and then the receiver plugged in your screen?

I second that. Does anyone know how many screens can be supported? I assume at least two?

LordPyrinc 13th January 2011, 00:46 Quote
Interesting concept, although I would prefer to have a device not integrated into the graphics card itself. Perhaps a device that plugs into the ports of the card. That way it would be easier to swap video cards or move the device to another pc if needed with little effort. That way you could also send the signal from a laptop to another display device.

This is definitely a start and could lead to some cool applications/enhancements in the future.

This would be the biggest problem i think. The card can transmit over miles for all we care. Unless my wireless remote/keyboard or whatever goes that far too, it's uses are a tad limited. Maybe as someone suggested, HTPC here to projector back there.

Unless some company out there makes a wifi keyboard? Keyboard with a ping.. That could get laggy...

It is called "Angel Hair cable (tm)" and its made for audiophile (idiots) with to much money to spend on non factual proven to be better wires.

The difference is, you could plug the Transmitter into anything, while this thing is stuck to your card, so you have to buy a new one soon :D
