Slight carry-over from a previous thread re expensive HDMI cables. Best advice for anyone who is still on the fence; take a look at what the professional market is doing, then order this HDMI cable, certified by HDMI to 2160p and resolutions up to 2560x1600 for £17.50 + vat. Who knows, it may become really useful when your TV can support that kind of resolution.
If the price tag puts you off, worry not, there are lower spec versions around too, for those resolutions mere mortals can support (1080p)...
