My purpose: connecting my small media center with HDMI port on my aged in dignity Beamer with AV connection. Funktnionierts? Yes, without any additional power source converts the converter to the digital HDMI signal into an analog signal. The image quality is very good for my 800x600 video projector. In addition, the sound in stereo quality output, creating a connection to the home theater system was possible. All good? Not quite. The unit is warm (but not hot), the audio signal seems a little low and the image was on my Beamer initially too large. The display control my media center but I could adjust the image size, so I had no disadvantage thereof.
