I have literally had two directly opposing replies on this from different providers, so over to the experts...

If you understand the question thank you for reading. I think I'll get the best reply here but Mods please do move if you don't

I have one PC, I want access points on ground and third floor of house so I have been looking at KVM and other ways of moving things around. My most likely set-up will be the PC itself downstairs, and the remote station upstairs. The PC outputs video through a DVI output, and (via an external DVI to HDMI adapter) will also output full video and audio from the DVI output. The card is ATI Radeon 4870 x2.

Since upstairs is for gaming on plasma TV/Projector, the remote video signal must by of this "full-fat" AV type i.e. video plus audio.

Ok so - I have found some excellent KVM solutions that carry DVI + USB over a dedicated Cat 5e/6 (which I could easily install). One supplier says since HDMI audio is interleaved in the overall signal he cannot see why his tx/rx extenders would not cope, but the other one (who came across as more helpful and quite knowledgeable) said that his were not specced for this so he thought they probably wouldn't.

OR - if HDMI over IP is not 'laggy' I'll just run the AV (HDMI) signal over IP through my gigabit LAN and get a USB extender - but remember, this is for gaming. Res would be 1920x1080 @ say 60Hz, audio 5.1, not "lossless" or 7.1.

As I haven't built any of it yet, while cost of components is a factor, cost of wiring etc. isn't really since I am building the LAN anyway

I won't even start yet thinking about handshaking and compatability groan

EDIT - I answered part of this for myself; it seems HDMI over IP is not noticeably laggy - but it uses compression not full HDMI bandwidth so there may be blocking etc. in final video output. A good resource for people who are interested is here http://justaddpower.net/VBS-Suite-fo...-products.html

Hello RoughRider

How much Lag you can cope with tends to vary from person to person - a bit of experimentation is probably in order before you bolt anything in place.

What audio system are you planning to use in the upstairs gaming room and how is the signal to be shared in the gaming room between the sound system, a TV and a Projector?
