Connect gaming PC to large-screen TV in the next room

[McBainUK]

I have a fast gaming PC in one room with DVI out and a plasma TV in the next room. What are my options for connecting them up?

Currently I'm thinking a long DVI cable and a long 3.5m stereo cable but it seems a shame to need to run 2 cables through the house every time I want to play.

Any single cable or even wireless options?

Hardware used:
Graphics card: XFX HD 5770 1GB
Motherboard: ASUS M4A77TD PRO 770 (with built-in sound)
TV: Panasonic Viera VIERA TXP42S20

Forget any wireless solution for audio/video. They're slow, have a very high latency, the quality is ugly.

As i can see, you're used plasma has 3 different hdmi inputs. Why not just using a hdmi cable, which transports audio analog to videosignals?

I see a "ATI HDMI Output" listed under Audio Devices in Device Manager. So you say a HDMI cable connected to the graphics card will carry sound too? If so that would be a good solution with only one cable

Yep, this one is it.

How long a run are you talking? HDMI starts to fall apart after a few metres (so I've read), and you can start to get "sparkles" in the picture. I've never seen it though, having only used HDMI over very short distances, so I don't know how much of a problem it is.

At home i have a standard 08 / 15 hdmi cable over a distance of 15 metres without any problems. No need for 200 $ cables or boosters. 15 meters are the standard if using cat 2 cables (or often wrong called HDMI 1.4 cables which has nothing directily to do with the category)

How long a run are you talking?

Will need 15 meters. They seem to about £20. eg.

From what I've read online, you need an ATI-specific DVI-to-HDMI converter to send the sound over the HDMI cable from an ATI video card.

his hd5770 almost surely has an HDMI port, so no need for a converter of any sort.

It's got 2
