smithdom:Thanks for the pointer to this product. I've just ordered the hdmi to dvi version of the cable to see what my laptop looks like on my 42PZ80B. For £3.99 it's got to be worth a punt! I'll report back on speed of delivery and whether or not the cable works.
Hmm, probably shouldn't quote myself, but it may help put this post into context.
Cable arrived today. Minimal packaging, just a jiffy bag and a plastic bag within. Post and packing probably cost less than £1 so that leaves £3 for the cable itself. Cable looks fine physically - no obvious quality issues. HDMI end of cable fits positively in the front HDMI socket on my TV, at least as secure as my other HDMI leads (QED included), although that isn't saying much.
Cranked up my PC and TV display worked straight away. Booted Ubuntu, then Windows and set screen resolution to 1920 x 1080 on both. Desktops on both too big for display at first, then found the option to switch off picture overscan on the TV and all fits fine. TV reports 1080p input. Windows desktop not as crystal clear as my LCD computer monitor, but perfectly servicable. Cranked up Bio Shock and set res to 1920 x 1080, and this looks stunning, easily as good as my monitor. DVD from PC looks OK, but I wouldn't expect it to match my BD35, and it doesn't.
I have no other DVI to HDMI cable to compare this cable with, but I have to say that it appears to do the job. On the basis of this I would definately try one of their regular HDMI leads if I ever needed another.
