Dual Link / Single Link / Cables

[tinners]

in a big way.

I have a Hyundai Q321 LCD and shortly to have a HTPC with Nvidia 6150 and want to connect the two using DVI. I will use the HTPC for DVDs and DivXs initially, eventually HD content.

Now I dont think either of these items supports dual link dvi - anyone know ?

Whatever the case can someone recommend me a cable of around 2m (sadly the 3m ones are too long). What difference will there be on my 32" screen from my HTPC depending upon the cable type I get. e.g. between a £20 cable and a £60 cable.

Thanks
