Set your display resolution so that it is equivalent to or lower than the resolution of other attendees' screens. In general, setting your resolution to 1024 x 768 pixels allows most attendees (even notebook users) to optimally view your shared application or document.
Size your application to be about the same size as the web collaboration window in the meeting room.
Don't cover your shared application with other windows. However, if you do, attendees will see a frozen image of the application you were sharing until the application is uncovered.
Keep in mind that sharing high color or textured slides take up more bandwidth than plain white background slides.
Presentation and application sharing support 24-bit color for all users who have the ability to view it. Keep in mind that for users who have less than 56k bandwidth, the system automatically detects a low bandwidth connection and defaults to 8-bit.
Allow a few seconds for other attendees' screens to update after making a change or moving to another page.
Avoid constant scrolling through your application. When you do need to move your document, use the Page Up and Page Down keys on your keyboard. Attendees can scroll through the visible portion of your document from their own desktops for better viewing.
Use simple meeting etiquette by verbalizing your intentions and requests. For example, let people know that you will be enabling collaboration. Likewise, let the meeting host know that you would like to take control of a document.
