How to stream office desktop activity to tv in living room? Best option?

[americanspirit]

I'm not even sure what the correct terminology is, so I can't even Google a query It's really quite simple and I bet there are a lot of options. Basically I am running XBMC on my Ubuntu 14.04 desktop in my office. I'd like to transmit the audio/video to my TV in the next room over. Other than running a 50ft HDMI what are my options?
The TV is "smart" (though I never use the feature) and I have an old Google Logitech Revue hooked up to it now.

a straight shot of hdmi is argueabley the best quality solution however....

if you have cat5e ran you could use a hdmi to cat5 adapter...

you could also look into the plair (or airplay/miracast) to stream over wifi...

there is also such a thing as wireless hdmi with special addapters but the range is bad and quality degrades with distance...
