This device, when plugged into my HP Pavilion Notebook, does exactly what I wanted it to do: output VGA to the VGA-to-Composite/S-Video convertor I have been using for years and so onwards to my defiantly non-HDMI TV set.And I needed the Audio output: the Pavilion shuts off its own headphone output (as well as its own speakers) when the HDMI cable is inserted.I did try it with a Roku 3, but the screen kept freezing during activation (which never completed), even when I used a 2.1A 5V USB charger to power the device. Perhaps that particular Roku 3 was defective.Note that the bulk of the advertising stresses attaching this to a computer, not a TV device. And, with a computer, it works very well indeed.
