Works perfectly.
I have a VGA cable from MY graphics card to my monitor.
An the DVI to HDMI cable from the DVI port of my graphics card to my T.V.
Please bare in mind despite one end being HDMI because the main connector is DVI it only carries video not audio. So u'll have to use seperate speakers or your monitor ones.
To set up, You then need to go to control panel, display, display settings, then select mutiple displays, instead of extended display to have both screens the same.
Quality is great an very good length more than enough for me but i ordered it over 3 Metres to make sure it'd reach.
Now i can watch all my movies on my 42inch LG T.V
Also have to commend amazon's delivery speed.
Used the free super saver delivery method ( 2-4 working days ). It got shipped wednesday evening, an arrived thursday morning ( 1.20.2011).
Amazing delivery speed an great product.
Five Stars.
