HDMI to VGA

There are plenty of connectors, cables, adapters or converters that a signal from HDMI to VGA Convert (as advertising). However, it should be clear to everyone that is a HDMI signal to a digital signal and a VGA, an analog signal.
The plug, cable or couplings offered only work if it is possible to switch the output of the HDMI signal to an analog PC output. I've never seen anything like it.
Therefore, one needs to either case a converter or transformer. Since the offers are varied and often there are products or devices that do not work so simply. As example would be the required power supply of the converter, which may not be sufficient by the HDMI cable and will have to be extended by a lack of mini USB cable (if at all a connection is available). Eventually, the resolution of the converter is not enough or the conversion itself is miserable. Audio is missing from many completely. The misconduct of the converter can be in every device in the customer reviews read (1-2 stars). You just have to make sure that the recommendations were not written because of incorrect use of the converters, for example, was searched and bought a HDMI VGA Converter VGA to HDMI converter.
To the offered here was currently nothing to read (new product from Amazon), but who had the main features. Own power supply or adapter as a side dish (goes with me but also without), high resolution and reasonable price segment. It was also important, which is output in the HDMI audio source separately to stereo mini-jack on the converter. I have a notebook has (Dell) the only one HDMI output and a Samsung TVs only VGA (SCART). The converter offered works perfectly so far. Long-term test or experience is lacking.
