KB01095 - What HDCP version does the AT-UHD-SW series support?


The AT-UHD-SW family is capable of passing HDMI signals up to HDCP 1.4. Please note any device in the system path will be analyzed for its HDCP compliance, therefore if using a mix of HDCP 1.4 and HDCP 2.2 devices, the sources will default to seeing the system as a being HDCP 1.4.

This means using sources or content that require the connection to be HDCP 2.2 (such as a 4K media streamer) and directly connecting this source to the Atlona switch, with a display directly connected to the Atlona’s output, will cause the source not to pass video. If your source can negotiate a signal at a lower resolution/HDCP format, this may help you get video to pass. Due to the fact that HDCP analyzation is done by the source, you may want to try connecting the source directly to your display, lowering the resolution it’s outputting to 1080p and reconnecting back to the Atlona switch to see if video is able to pass (at lower resolutions). If video passes, you can leave the source at 1080p and enjoy HD video. If you are unable to get video to pass and get the same HDCP message, it appears your source will not pass video unless the entire system path supports HDCP 2.2.

There is no way to change the AT-UHD-SW’s HDCP compliance, however, Atlona will be releasing HDCP 2.2 compatible products in the near future. For more info, please sign up for our newsletter.
