    Two Issues, otherwise great

    Pros: Good Quality
    Low Price

    Cons: Occasional flickering occurs (unlplugging and replugging the HDMI cable seems to fix it)
    Does not pass HD Audio codecs like Dolby TrueHD and DTS-MA (This is a limitation of the adapter type, not a problem with the product)

    This cable is great but experienced one issue with the actual product. I received some occasional flickering when using the adapter. Unplugging and replugging the HDMI cable seemed to fix it, but I don't know it will continue to occur.

    I was aware the adapter would pass audio, however, did not realize it was unable to carry HD Audio formats such as Dolby TrueHD and DTS-MA. LPCM up to 7.1 channels, however, works fine. Can't knock the product as this seems to be a limitation with adapters like this one.

    Our engineers are very satisfied with these. If they are happy with them then we continue to use them. The price & quality are good as well.

    Bought three of these a few weeks back and have had no issues. I bought these to use with display emulators (dummy plugs) for Virtual Desktop.
