I frequently use the CAC-1080 for professional multi-monitor installation projects.

Recently, I noticed that newly purchased CAC-1080 adapters have an additional “Rev.A” label attached to them.

When I used these Rev.A units alongside older CAC-1080 adapters, I observed slight differences in color reproduction and brightness between displays.

To investigate further, I analyzed the output signal from the Rev.A units using an HDMI analyzer. The results indicated that the lower 4 bits of the video data appear to be missing. In addition, I observed significant jitter on the TMDS clock. Depending on the monitor being used, this can lead to frequent blackouts or signal instability.

Because of these findings, I am beginning to wonder whether these Rev.A units might differ from the original product design, or potentially even be counterfeit products.

Has anyone else experienced similar issues with CAC-1080 adapters marked “Rev.A”?

Any information about hardware revisions, firmware changes, or manufacturing differences would be greatly appreciated.
