【WebexMeeting】 I would like the quality of the material delivered through the switcher not to drop.

【WebexMeeting】 I want to make sure that the quality of the materials delivered by the switcher does not deteriorate.

We are using it for training.

For delivery reasons, we use a switcher to switch between PowerPoint and other materials. The machine looks like a TV station.

We don't use the sharing function of Webex.

When I used the switcher to display PowerPoint, the quality of the image deteriorated and small letters became blurred and unreadable.

Does this mean that the image quality is being delivered at a reduced level? Is there any way to improve the image quality?
