More modern stuff with HDMI can use sound though this, so only need one lead.

I can personally recommend the HDMI route, I have a Sapphire HD5770 GPU, which has 2 DVI-D, a DP and a HDMI connection on the back of it... I have set up my Media Player to use the "ATI High Definition Audio Device" as it's default sound device and all videos get played via the TV and anything else comes out of the computer speakers via the default on-board sound card..

Is much better than watching on the TV and the sound coming from your computer desk ;)

I will however make one statement against the idea, and that is to not use it as a monitor via HDMI.. I find it very difficult the read anything on my 42" TV.. the definition of lines etc, and font is pretty appalling on my TV, having said that it is an old Panasonic Viera.. but this still also occurs on my http://www.ebuyer.com/product/165288 standard computer monitor when I plug that in via HDMI also.. So am assuming this is just one of the downfalls of HDMI over DVI-D.

Hope this helps
