The Galaxy GTX 460 WHDI Graphics Card

In most ways, the Galaxy GTX 460 WHDI is just a normal graphics card with a few things both internally and externally that would make it stand out from the crowd at a LAN part. 


The outside of the box makes sure you realize that some wireless things are happening here with the WHDI logo prominently displayed. 



Through the magic of Guile's Sonic Boom, video will be transferred to your TV

The WHDI card is a bit longer than your standard GTX 460 card and you'll see why once we tear off the cover.  The metal cover is a bit loose feeling and surely helps with some shielding for the transmitter antennas below it. 

The card still requires a pair of 6-pin PCIe power connectors to operate. 

Looking at the connections on the card you see a couple of standard ones: a dual-link DVI output and a DisplayPort connection.   There are five standard antennae connections that look familiar to anyone that is seen a desktop WiFi card or a motherboard with WiFi built on and those will indeed be used to transmit the WHDI data to the receiver.  The mini-USB connection there is used to flash the firmware on the WHDI chip; very forward looking of Galaxy and handy for users going forward. 

These are
five antennas...

...and here they are attached to the Galaxy GTX 460 WHDI card. 
Insert Cthulhu reference here. 

The back side of the card doesn't really reveal anything about the secrets within but removing the cover might.  What the back does reveal is the lack of an SLI connection on this card - disappointing considering doubling up the performance of the GTX 460 would take away any issues of the best quality gaming at 1080p resolutions.  

Under the hood we see the GTX 460 GF104 GPU and the 1GB of GDDR5 memory that all cards of the same chip contain but it is the tangle of wires and shielding to the left that is more interesting.

The AMIMON 2120 transmitter chip is located in the image above, sticking out just below the silver shielding panel, attached to the riser card.  This complicated mash-up of technology is what is required today to transmit as much as 3 Gbps of bandwidth throughout a home, or in this case, just to the receiver box Galaxy includes. 

Included in the box with the Galaxy GTX 460 WHDI card are your standard allotment of accessories including a pair of power adapters, DVI-to-VGA converter, instructions and driver disc.  The two USB cables are used for firmware updates of the logic on the WHDI card and receiver as well as another neat feature we'll mention below. 

To complete the WHDI connection you'll need the receiver shown above.  A small box that measures about 6" x 4" without the stand includes the AMIMON 2220 receiver controller and outputs and HDMI connection to your desired monitor, TV, receiver, etc.  Galaxy did include a 6' HDMI cable as well.

I purchased a Galaxy 460 from Newegg. I was able to get the DVI output to work but could not find a standard HDMI cable to fit the HDMI input on the Galaxy 460. When PCPerspective tested the Galaxy 460 what type of cable did you use to connect to the HDMI input. I cannot find any standard HDMI cable that connects with this card. I RMA the first card back. I just received the second card and I still have the same problem. Galaxy is no help on this problem. Do you guys remember what type of cable you used to test your Galaxy 460 WHDI card. Thanks so very much for your help.

you need a DisplayPort to HDMI adapter. you can find it on Google:) the port you're trying to fit an HDMI cable into is a Displayport,not HDMI.

You can use a DisplayPort to HDMI adapter or accomplish the same thing for much less using a simple DVI to HDMI adapter. Since DVI uses the same TDMS signal as HDMI and DVI is capable of HDCP.

With the Display Port, Wireless HDMI, and DVI, you have the potential of 3 HDMI outputs with this card. Great for a triple plasma gaming rig?

Up to a maximum operating in the same place a few possible?

very nice review. I do have a question. Did you try the 3d Vision with a DLP projector. I feel the 3D vision may work at 720p 120 Hz.

This may be a silly question, but how does the sound work? Is it integrated into the graphics card and I gotta get rid of my current sound card? I want the wireless solution but I don't fully understand how to rig it up.

It outputs sound just like a wired HDMI 1.4 connection would. It is not a replacement for your PCs sound card but a way to stream audio at the same time as the video.

I am not sure what I am missing here. With the price and at a 40 foot distance (or even at 100 feet) what is preventing one from just buying a HDMI cable (50 or even 100 feet) and some USB for the keyboard and mouse? I am sure that with the length of USB there could be some issues with lag, but I am sure that any lag would not be outside any that you may have experienced from time to time.

This would allow you to connect a PC to a TV for under $100US for 100feet and half that for 50 feet.

Is there an additional interface that this brings to the table that allows one to physically connect to a TV or isn't it just a matter of getting these 3 things to the TV.

Granted, you would need a device to get the keyboard/mouse connected to the TV, but surely that is already out there.
