Hi @jiedesheng,

Thanks for using Zoom SDK. What is the “card” you are referring to? Are you experiencing the same resolution if you are running the Zoom Windows Client on the same machine and same network?

Thanks!

Hi @jiedesheng,

Thanks for the reply. What is the “card” you are referring to? Could you provide the SDK log for us to further investigate?

Thanks!
