This is a high quality, 2.0M long, brand new, RoHS compliant, sealed lead which will give a good quality analogue signal.
Please note - your television must be capable of tuning to "analogue" signals to be able to use this lead with your computer. Since the conversion of terrestrial TV signals to digital, many new flat screen TV's do not now have an analogue tuner.
To check, go into the tuning menu of your TV and select "setup" or "tune channels" (they all use a slightly different description for the same thing). If your TV can tune analogue signals, it is shown in the tuning options available when you start the tuning process.
