Due to resolution mismatch, streaming will fail when attempting to stream at 4K. If the input source resolution is 4K@60, while the connected monitor supports a maximum resolution of 1080p@60.
We recommend using the same resolution on both the input and output sides, either 4K@60 or 1080p@60.
If you do not have a 4K-supported monitor, configure the pipeline to stream from a 4K input source to a 1080p output. Please follow the commands below to configure this setup.
