@SteveWilkinson83 We appreciate you taking the time to post on our Community forum!
We are sorry to hear that you experienced difficulty with our CDP2HDFC. We typically see this behavior if the host’s USB-C port does not support DP Alt, which is video out capabilities. Can you please provide the full make and model of the computer being used? This will help confirm if this is the case or not.
Thank you in advance, and we look forward to hearing from you!
