Wireless Gaming, Blu-ray and General Usage
Now that we had everything installed and working, it was time to really put this new hardware to the test.  Can the WHDI technology live up the claims on near zero latency, streaming through walls with an uncompressed video stream?

The first test was to see if Blu-ray was working up to our standards – both in terms of image quality and also just WORKING with the questions about HDCP coming to mind.  As you can see here I was watching the Ironman Blu-ray without any problems with copy protection or image quality; I did connect the GTX 460 WHDI directly to the same TV with a DVI-to-HDMI cable and did my best “close up” test and couldn’t see any different in image quality, colors or noise levels.

As for the audio, you should know that any format that can be transmitted from the GTX 460 to the TV is supported here with the wireless connection as well, including the uncompressed LPCM 7.1 channel offering for bit-streaming audio. 



In this short, and almost completely useless video (obviously you can’t see image quality in a YouTube clip), we show the 50″ Panasonic VIERA Plasma TV sitting next to the Galaxy WHDI receiver.  Unfortunately for you all, this review was delayed a couple of hours as I “accidentally” caught myself watching this movie in several instances throughout the testing phase. 

Other than video playback, the other primary use case for buyers of this card is for PC gaming on a big screen TV while keeping the computer further away or in a different room completely.  The image quality was great in my experiences I spent a couple of hours playing Left 4 Dead 2 and Metro 2033.  L4D2 had no problem running at maximum settings at 1920×1080 though with Metro I backed off on the image quality a bit, but kept the 4xMSAA because of the larger pixels on a TV.  The experience was just as good as being connected with a cable and neither I, nor any of the other people that stopped by to see the rig in action, noticed any mouse/keyboard lag. 

It would seem that the near-zero latency claim is as accurate as we can test.  Just to double check ourselves we had the audio output from PC connected speakers rather than from the TV with HDMI audio can never saw lip-sync issues with dialogue.

Finally, the range of this card needed to be tested.  Due to the constraints of our PC Perspective office space and my desire to NOT take the TV/receiver combination out in the snow, the furthest apart we could get the two WHDI components was about 40 feet with three walls between them, direct line of sight.  You can see the arrangement in the panoramic photo above: the TV is in the bottom left of the image on the floor with a Windows desktop being displayed and the PC running it is located WAAAAY back in the office on the right next to the smaller TV. 

In that situation we again sat through a good 40 minutes of the Ironman Blu-ray and played some games and noticed zero changes in the appearance, quality or sync level.  While I didn’t quite test the range quote of 100 feet, I think 40 feet is a pretty good distance to cover with this implementation.  The walls between these rooms were interior walls, nothing built out of concrete or anything like that, so your mileage may vary but for most configurations I think the Galaxy WHDI card will live up to its claims.
