The TE30 endpoint was upgraded to the latest firmware version (V100R001C10SPC300) and when the Air Content Sharing client was used it was discovered that the presentation shared to the remote side could not be seen properly (the image was scrambled).
The Air Content Sharing client support coded transmission resolutions of 720p and 1024 x 768 pixels and a maximum frame rate of 15 fps.
If a higher value is set on the computer/laptop used to share a presentation the device will not support it thus the image will be scrambled
Changing the resolution to the recommended one (1024 x 768) solved this particular issue.
Since Huawei has multiple endpoints and each of them have different performances, please see below a list with resolution that can be supported on Huawei endpoints
